System Applications
Water Loop Application
Commercial systems typically include a number of
units connected to a common piping system. Any unit
plumbing maintenance work can introduce air into the
piping system; therefore air elimination equipment is a
major portion of the mechanical room plumbing. In piping
systems expected to utilize water temperatures below
50°F [10°C], closed cell insulation is recommended on
all piping surfaces to eliminate condensation (extended
range units required). Metal to plastic threaded joints
should never be used due to their tendency to leak over
time. All SmartSource units include flush mounted FPT
water connections integral to the unit corner post, which
do not require a backup wrench.
A thread sealant is recommended to minimize internal
fouling of the heat exchanger. Do not over tighten
connections and route piping so as not to interfere with
service or maintenance access. Hose kits are available
from Daikin in different configurations for connection
between the unit and the piping system. Depending
upon selection, hose kits may include shut off valves,
P/T plugs for performance measurement, high pressure
stainless steel braided hose, “Y” type strainer with blow
down valve, and/or “J” type swivel connection. Balancing
valves and an external low pressure drop solenoid valve
for use in variable speed pumping systems may also be
included in the hose kit.
The piping system should be flushed to remove dirt,
piping chips, and other foreign material prior to operation
(see "Cleaning & Flushing System" on page 29. The
water flow rates should be kept at approximately 3 GPM
per nominal cooling ton (a 10°F temperature rise in
cooling). To ensure proper maintenance and servicing,
P/T ports are imperative for temperature and flow
verification, as well as performance checks.
Water loop heat pump (cooling tower/boiler) systems
typically utilize a common loop, maintained between 60 90°F [16 - 32°C]. The use of a closed circuit evaporative
cooling tower with a secondary heat exchanger between
the tower and the water loop is recommended. If an
open type cooling tower is used continuously, chemical
treatment and filtering may be necessary.
Ground-Loop Application
CAUTION
The following instructions represent industry accepted
installation practices for closed loop earth coupled heat pump
systems. Instructions are provided to assist the contractor in
installing trouble free ground loops. These instructions are
recommendations only. State/provincial and local codes MUST be
followed and installation MUST conform to ALL applicable codes.
It is the responsibility of the installing contractor to determine and
comply with ALL applicable codes and regulations.
CAUTION
Ground loop applications require extended range equipment and
optional refrigerant/water circuit insulation.
Pre-Installation
Prior to installation, locate and mark all existing
underground utilities, piping, etc. Install loops for new
construction before sidewalks, patios, driveways, and
other construction has begun. During construction,
accurately mark all ground loop piping on the plot plan
as an aid in avoiding potential future damage to the
installation.
Piping Installation
The typical closed loop ground source system is shown
in Figure 2 on page 9. All earth loop piping materials
should be limited to polyethylene or equivalent per
International Ground Source Heat Pump Association
(IGSHPA)
Figure 1: Polyethylene fused piping
Galvanized or steel fittings should not be used at any
time due to their tendency to corrode. All plastic to metal
threaded fittings should be avoided due to their potential
to leak in earth coupled applications. A flanged fitting
should be substituted. P/T plugs should be used so that
flow can be measured using the pressure drop of the
unit heat exchanger.

Earth loop temperatures can range between 25 and
110°F [-4 to 43°C]. The water flow rates should be kept
at approximately 3 GPM per nominal cooling ton (a 10°F
temperature rise in cooling).
Test individual horizontal loop circuits before backfilling.
Test vertical U-bends and pond loop assemblies prior to
installation. Pressures of at least 100 psi [689 kPa] should
be used when testing. Do not exceed the pipe pressure
rating. Test entire system when all loops are assembled.
Calculate the total volume of fluid in the piping system.
Then use the percentage by volume shown in Table 6 on
page 10 for the amount of antifreeze needed. Antifreeze
concentration should be checked from a well mixed sample
using a hydrometer to measure specific gravity.
Figure 3: Flushing the loop
Flushing the Earth Loop
Upon completion of system installation and testing, flush
the system to remove all foreign objects and purge to
remove all air.
Antifreeze
In areas where minimum entering loop temperatures
drop below 50°F [10°C] or where piping will be routed
through areas subject to freezing, antifreeze is required.
Alcohols and glycols are commonly used as antifreeze;
however your local sales office should be consulted
to determine the antifreeze best suited to your area.
Freeze protection should be maintained to 15°F [9°C]
below the lowest expected entering loop temperature.
For example, if 30°F [-1°C] is the minimum expected
entering loop temperature, the leaving loop temperature
would be 22 to 25°F [-6 to -4°C] and freeze protection
should be at 15°F [-10°C]. Calculation is as follows: 30°F
- 15°F = 15°F [-1°C - 9°C = -10°C].
All alcohols should be premixed and pumped from
a reservoir outside of the building when possible or
introduced under the water level to prevent fumes.

Ground-Water Application
Open Loop - Ground Water Systems - Typical open
loop piping is shown in Figure 4. Shut off valves should
be included for ease of servicing. Boiler drains or other
valves should be installed in the supply and return lines
to allow cleaning of the heat exchanger. Shut off valves
should be positioned to allow flow through the coax via
the boiler drains without allowing flow into the piping
system. P/T plugs should be used so that pressure drop
and temperature can be measured. Piping materials
should be limited to copper.
WARNING
PVC or CPVC should not be used as they are not compatible
with the POE oils used in HFC-410A products and piping system
failure and property damage may result.
IM 1139-8
Water quantity should be plentiful and of good quality.
See "Water impurities, result & recommended water
system application" on page 13 for water quality
guidelines. The unit can be ordered with either a
copper or cupro-nickel water heat exchanger. Consult
Table 8 on page 13 for recommendations. Copper
is recommended for open loop ground water systems
that are not high in mineral content or corrosiveness.
In conditions anticipating heavy scale formation or
in brackish water, a cupro-nickel heat exchanger is
recommended. In ground water situations where scaling
could be heavy or where biological growth such as iron
bacteria will be present, an open loop system is not
recommended. Heat exchanger coils may over time lose
heat exchange capabilities due to build up of mineral
deposits. Heat exchangers must only be serviced by
a qualified technician, as acid cleaning and special
pumping equipment may be required.

Water Quality Standards - Table 8, Water impurities,
result & recommended water system application"
on page 13 should be consulted for water quality
requirements. Scaling potential should be assessed
using the pH/Calcium hardness method. If the pH
<7.5 and the calcium hardness is less than 100 ppm,
scaling potential is low. If this method yields numbers
out of range of those listed, the Ryznar Stability and
Langelier Saturation indices should be calculated. Use
the appropriate scaling surface temperature for the
application, 150°F [66°C] for direct use (well water/
open loop); 90°F [32°F] for indirect use. A monitoring
plan should be implemented in these probable scaling
situations. Other water quality issues such as iron
fouling, corrosion prevention and erosion and clogging
should be referenced in Table 8 on page 13.
Expansion Tank and Pump - Use a closed, bladder
type expansion tank to minimize mineral formation due
to air exposure. The expansion tank should be sized to
provide at least one minute continuous run time of the
pump using its draw-down capacity rating to prevent
pump short cycling. Discharge water from the unit is not
contaminated in any manner and can be disposed of in
various ways, depending on local building codes (e.g.
recharge well, storm sewer, drain field, adjacent stream
or pond, etc.). Most local codes forbid the use of sanitary
sewer for disposal. Consult your local building and
zoning department to assure compliance in your area.
www.DaikinApplied.com
11
Water Control Valve - Note the placement of the
water control valve in Figure 4. Always maintain water
pressure in the heat exchanger by placing the water
control valve(s) on the return line to prevent mineral
precipitation during the off-cycle. Pilot operated slow
closing valves are recommended to reduce water
hammer. If water hammer persists, a mini-expansion
tank can be mounted on the piping to help absorb the
excess hammer shock. If a field provided motorized
valve and actuator is utilized, ensure that the total
‘VA’ draw of the valve can be supplied by the unit
transformer. For instance, a slow closing valve can draw
up to 35VA. Units are furnished with a factory-installed
50 VA transformer. An optional 75VA transformer is also
available. A typical pilot operated solenoid valve draws
approximately 15VA (see Figure 45 on page 48).
IM 1139-8
System Applications
Flow Control - Flow control can be accomplished by
two methods. One method involves simply adjusting
the field-provided ball valve or flow control valve on
the return line. Measure the pressure drop through
the unit heat exchanger, and determine flow rate from
Table 7. Since the pressure is constantly varying, two
pressure gauges may be needed. Adjust the valve until
the desired flow of 1.5 to 4 gpm, per ton [5.7 to 15.1 l/m,
per kW] is achieved. A second method of flow control
requires a flow control device mounted on the outlet of
the flow control valve. This device is typically a brass
fitting with an orifice of rubber or plastic material that is
designed to allow a specified flow rate. On occasion,
flow control devices may produce velocity noise that
can be reduced by applying some back pressure from
the ball valve located on the discharge line. Slightly
closing the valve will spread the pressure drop over both
devices, reducing the velocity noise.

Water System Quality
The cleaning, flushing and chemical treatment of a water
source heat pump system is fundamental to efficient
operation and the life expectancy of the system.
Potential system problems produced by the use of water
fall into three general categories:
1. Scale formation – Mineral deposits which result from
the crystallization and precipitation of dissolved salts
in the water. The deposits form an insulating barrier,
reducing the heat transfer rate and impeding the
circulation of fluids due to increased pressure drop.
2. Corrosion – Decomposition of the metal caused
by absorption of gases from the air. Corrosion may
occur in any metal component of the system.
3. Organic growths – Slime and algae which form
under certain environmental conditions, and
can reduce the heat transfer rate by forming an
insulating coating or can promote corrosion by
pitting.
The system water should be evaluated for degrees of
impurity, with testing available from independent testing
labs, health departments or state agencies.
Table 8 on page 13 is a list of water characteristics,
the potential impurities and their results and the
recommended treatment.
Avoiding Potential Problems
As shown in Table 8 on page 13, all water contains
some degree of impurities which may affect the
performance of a heat pump system. The use of a cupronickel coil can help avoid potential problems. Water flow
rates should:
• Be high enough that the temperature rise through
the heat exchanger does not exceed 12° F when
operating in the cooling mode.
•
12
Not exceed 4 GPM per nominal ton. Flow rates that
have velocities of 10 feet per second or more may
cause pipe erosion and heat exchanger failure.

2. Cupro-nickel is recommended if iron bacteria is high, suspended solids or dissolved oxygen levels are high.
3. If the concentration of these corrosives exceeds the maximum tabulated in the cupro-nickel column, then the potential for serious
corrosion problems exists.

Supply & Return Piping
Pre-Installation Considerations
All units should be connected to supply and return piping
in a two-pipe reverse return configuration. A reverse
return system is inherently self-balancing and requires
only trim balancing where multiple quantities of units with
different flow and pressure drop characteristics exist in
the same loop.
A direct return system may also work acceptably, but
proper water flow balancing is more difficult to achieve
and maintain.
• The piping can be steel or copper.
Note: Polyolester Oil, commonly know as POE oil is a
synthetic oil used in many refrigeration systems.
POE oil, if ever in contact with PVC/CPVC will
coat the inside wall of PVC/CPVC pipe causing
environmental stress fractures.
It is recommended that PVC/CPVC piping is not
used in the installation of the loop system, as system failure and property damage could result.
Supply and return runouts usually join the unit via short
lengths of high pressure flexible hose which are sound
and vibration isolators for both unit operating noise and
hydraulic pumping noise.
•
One end of the hose should have a swivel fitting to
facilitate removal for service.
Note: 1. No unit should be connected to the supply
and return piping until the water system has
been cleaned and flushed completely, see
"Cleaning & Flushing System" on page 29.
After the cleaning and flushing has taken
place, the initial connection should have all
valves wide open in preparation for water
system flushing.
2. Hard piping is not recommended since no
vibration or noise attenuation can be accomplished.
3. Supply and return shutoff valves are required
at each unit. The return valve can be used
for balancing. When used it should have a
“memory stop” so that it can be closed off,
and reopened to the proper position for the
required flow.
4. Do not over-torque fittings. The maximum
torque without damage to fittings is 30 foot
pounds. If a torque wrench is not available,
use as a rule of thumb, finger tight plus one
quarter turn.

Discharge Air Conversion
Installation Considerations
1. Locate the unit in conditioned space and avoid
installation in corrosive environments. Allow
clearance for easy removal of the filter and access
panels, and enough space for service personnel to
perform maintenance or repair.
2. Remove the Styrofoam shipping block under the fan
housing before start-up. Figure 6.
3. Make sure that sufficient access has been provided
for installing and removing the unit, including
clearance for duct collars and fittings at water and
electrical connections (see Figure 10).
A straight discharge unit may be converted to an end
discharge by doing the following:
Note: The information covered in this section of the
blower assembly orientation is typical of Daikin
units. Regardless, if you are changing end to
straight or straight to end the blower assembly
has to turn 90 degrees and simultaneously rotate
180 degrees to achieve the proper orientation.
Not all Daikin units will have the same air discharge location but will have the same general
results when following the instructions.
DANGER
4. Unit condensate drains are not internally trapped.
External trap is required. Allow adequate room around
the unit for condensate piping.
Hazardous Voltage! Disconnect all electric power
including remote disconnects before servicing.
Failure to disconnect power before servicing can
cause severe personal injury or death.
5. If the unit is installed in a confined space, provisions
must be made for return air to freely enter the face of
the unit’s air coil.
Figure 6: Horizontal unit foam shipping block
CAUTION
Sharp edges can cause personal injury. Avoid contact with them.
6. Turn off power to the unit at the breaker box.
7. Remove the top panel by removing the screws
around the perimeter of the top securing it to the
lower cabinet (Figure 7 on page 15).

Ductwork and Attenuation
Discharge ductwork is normally used with these
conditioners. Return air ductwork may also be required.
All ductwork should conform to industry standards of
good practice as described in the ASHRAE Systems
Guide.
A field supplied discharge duct system will normally
consist of:
• a flexible connector at the unit
•
a 10 ft. length of insulted duct
•
and a trunk duct teeing into a branch duct with
discharge diffusers as shown in Figure 14
With metal duct material, the entire branch duct should
be internally lined with acoustic fibrous insulation for
sound attenuation. Glass fiber duct board material is
more absorbing and may permit omission of the flexible
boot connector.
As a general recommendation, the acoustic fibrous
insulation should be at least 1/2 inch thick over the
entire duct run (Figure 14). For better sound attenuation,
line the last five diameters of duct before each register
IM 1139-8
with a one-inch thick sound blanket. Elbows, tees and
dampers can create turbulence or distortion in the
airflow. Place a straight length of duct, 5 to 10 times the
duct width, before the next fitting to smooth out airflow.
Diffusers that are located in the bottom of a trunk duct
can also produce noise. For this same reason, volume
control dampers should be located several duct widths
upstream from an air outlet.
For Hotel, Motel, Dormitory or Nursing Home
applications that use a single duct discharge, a velocity
of 500 to 600 fpm is suggested. These applications
typically have static pressures as low as 0.05 inches of
water and duct lengths approximately six feet in length.
The discharge duct must be fully lined and have a
square elbow without turning vanes. Return air for these
applications should enter through a “low” sidewall filter
grille and route up the stud space to a ceiling plenum.
For horizontal heat pumps mounted from the ceiling,
an insulated return plenum is sometimes placed at the
return air opening to further attenuate line-of-sight sound
transmission through return openings.

Installation
Return Air Filter Rack Assembly &
Duct Collar Connections
Return air ductwork can be connected to the standard
filter rack, see Figure 16 on page 19. The unit comes
standard with a 2" (51mm) thick factory-installed
throwaway filter, mounted in a 4-sided combination
filter rack and return air duct collar. Filters can be
easily removed from either side by interchanging the
removable filter door to the right or left side and rotating
the filter rack assembly 180 degrees. Do not use sheet
metal screws directly into the unit cabinet for connection
of supply or return air ductwork, especially return air
ductwork which can hit the drain pan or the air coil.

Ventilation Air
Ventilation may require outside air. The temperature of
the ventilation air must be controlled so that mixture of
outside air and return air entering the conditioner does
not exceed conditioner application limits. It is also typical
to close off the ventilation air system during unoccupied
periods (night setback).
The ventilation air system is generally a separate
building subsystem with distribution ductwork. Simple
introduction of the outside air into each return air plenum
chamber reasonably close to the conditioner air inlet is
recommended. Do not duct outside air directly to the
conditioner inlet. Provide sufficient distance for thorough
mixing of outside and return air. See "Operating Limits"
on page 48.

Piping
Condensate Drain Connection
A field provided condensate trap must be installed on
each water source heat pump. Condensate removal
piping must be pitched away from the unit not less than
1/4" per foot. The vent should extend at least 1-1/4"
above the unit condensate fitting. A vent is required after
the trap so that the condensate will drain away from
the unit. The vent can also act as a clean out if the trap
becomes clogged. To avoid having waste gases entering
the building, the condensate drain should not be directly
piped to a drain/waste/vent stack. See local codes for
the correct application of condensate piping to drains
Figure 36: Unit condensate drain pipe trap detail
1-1⁄2" (38mm)
2. Do not locate any point in the drain system above
the condensate drain connection of any unit.
It may be necessary to manually fill the trap at system
startup, or to run the unit for sufficient time to build a
condensate seal. The condensate trap and condensate
piping drainage should be free of any foreign debris.
Debris can prevent proper drainage and unit operation
and result in condensate buildup.
Optional
Field- Installed Vent
1⁄4" Per Foot
(21mm Per Meter)
1-1⁄2"
(38mm)
Note: Improper trapping can lead to several problems. If the trap is too tall, negative pressure will
prevent drainage, causing condensate backup. If
the trap is too short the seal will be destroyed or
nonexistent, producing the same effect as a nontrapped system.
1. Each water source heat pump is provided with
a 3/4" FPT flush mount fitting for connection of
a condensate drain. A complete copper or PVC
condensate system can be used. Copper or steel
condensate piping should be insulated to prevent
sweating. In most applications the use of PVC
prevents sweating of condensate drain.

Piping
Cleaning & Flushing System
3. Shut off supplemental heater and circulator pump
and open all drains and vents to completely drain
down the system. Short circuited supply and return
runouts should now be connected to the conditioner
supply and return connections. Do not use sealers
at the swivel flare connections of hoses.
1. Prior to first operation of any conditioner, the water
circulating system must be cleaned and flushed of
all construction dirt and debris.
If the conditioners are equipped with water shutoff
valves, either electric or pressure operated, the
supply and return runouts must be connected
together at each conditioner location. This will
prevent the introduction of dirt into the unit. See
Figure 38.
4. Trisodium phosphate was formerly recommended
as a cleaning agent during flushing. However,
many states and localities ban the introduction of
phosphates into their sewage systems. The current
recommendation is to simply flush longer with warm
80°F (27°C) water.
Figure 38: Supply & return runouts connected together

2. Fill the system at the city water makeup connection
with all air vents open. After filling, close all air
vents.
The contractor should start main circulator with
the pressure reducing valve open. Check vents
in sequence to bleed off any trapped air, ensuring
circulation through all components of the system.
Power to the heat rejector unit should be off, and
the supplementary heat control set at 80°F (27°C).
While circulating water, the contractor should check
and repair any leaks in the piping. Drains at the
lowest point(s) in the system should be opened for
initial flush and blowdown, making sure city water
fill valves are set to make up water at the same
rate. Check the pressure gauge at pump suction
and manually adjust the makeup to hold the same
positive steady pressure both before and after
opening the drain valves. Flush should continue for
at least two hours, or longer if required, to see clear,
clean drain water.
www.DaikinApplied.com
29
5. Refill the system with clean water. Test the water
using litmus paper for acidity, and treat as required
to leave the water slightly alkaline (pH 7.5 to 8.5).
The specified percentage of antifreeze may also be
added at this time. Use commercial grade antifreeze
designed for HVAC systems only. Do not use
automotive grade antifreeze.
Once the system has been filled with clean water
and antifreeze (if used), precautions should
be taken to protect the system from dirty water
conditions. Dirty water will result in system wide
degradation of performance and solids may clog
valves, strainers, flow regulators, etc. Additionally,
the heat exchanger may become clogged which
reduces compressor service life or causes
premature failure.
6. Set the loop water controller heat add setpoint
to 70°F (21°C) and the heat rejection setpoint to
85°F (29°C). Supply power to all motors and start
the circulating pumps. After full flow has been
established through all components including the
heat rejector (regardless of season) and air vented
and loop temperatures stabilized, each of the
conditioners will be ready for check, test and startup, air balancing, and water balancing.

Jumper Configuration Settings
WARNING
Figure 40: Configuration jumpers location
Proper antifreeze/water solution is required to minimize the
potential of fluid freeze-up. Jumper JP3 is factory set for water
freeze protection with the jumper open. Operation at fluid
temperatures below 32°F with anti-freeze protection requires JP3
to be field configured for the jumper closed. If unit is employing
a fresh water system (no anti-freeze protection), it is extremely
important that JP3 jumper setting remains in the open position
(factory default setting) in order to shut down the unit at the
appropriate water temperature to protect your heat pump from
freezing. Failure to do so can result in unit damage, property
damage and will void unit warranty.

MicroTech® III SmartSource Unit
Controller
Table 18: MicroTech III SmartSource unit controller fault &
status LED's
The MicroTech III SmartSource unit controller allows
thermostat, Daikin sensor and DDC standalone operation.
The R (24VAC) terminal is used to operate thermostat
inputs G, Y1, Y2, W1, W2, W3, W4 and TB1-1. The C
(0VAC) terminal is used to control inputs U, E and O.
No external power sources may be used to operate
the MicroTech III controller. All units must be properly
grounded per local code requirements.
NOTICE
For information on sequence of operation and troubleshooting refer to OM 1149-xx.
Remote Reset of Automatic Lockouts
The Remote Reset feature provides the means to
remotely reset automatic lockouts. There are (3) means
to reset an automatic lockout condition:
• Using the thermostat create 2 demands for capacity
within 30 seconds
•
Press the Room Sensor or Thermostat Timed
Override/Reset Button for more than 10 seconds
•
Turn the unit power off

Note: Mode/faults are listed in order of priority.
When the cause of the fault condition has been cleared,
and the unit transitions from not requiring any capacity
to needing any capacity twice within 30 seconds
(accomplished by user manipulation of the Heat/Cool/
Auto/Off switch on the thermostat), an alarm reset
equivalent to a tenant override button reset is generated.
The intelligent reset counter and the 24 hour timer are
cleared when this type of alarm reset is generated.
Note: This feature only applies to thermostat controlled
systems.
For room sensor controlled units, pressing the “Override”
or “Reset” button for more than 10 seconds will apply a
ground signal to the tenant override in(screw terminal
connection at TB1 pin 4) will clear the lockout alarm
once the cause of the fault condition has been cleared.
A unit power cycle can also be used to clear an
automatic lockout if the conditions causing the fault have
been cleared.

Start-up
Information for Initial Start-up
†† Set thermostat to “Heat.” If the thermostat is the
automatic changeover type, set system switch to
the “Auto” position and depress the heat setting
to the warmest selection. Some units have built-in
time delays which prevent the compressor from
immediately starting. With most control schemes,
the fan will start immediately. After a few minutes of
compressor operation, check for warm air delivery
at discharge grille. If this is a “cold building” start-up,
leave unit running until return air to the unit is at least
65°F (18°C).
Measure the temperature difference between
entering and leaving air and entering and leaving
water. With entering water of 60°F to 80°F (16°C to
27°C), leaving water should be 6°F to 12°F (3.3°C to
6.6°C) cooler, and the air temperature rise through
the machine should not exceed 35°F (19°C). If the
air temperature exceeds 35°F (19°C), then the water
flow rate is inadequate.
CAUTION
Units must be checked for water leaks upon initial water system
start-up. Water leaks may be a result of mishandling or damage
during shipping. Failure by the installing contractor to check for
leaks upon start-up of the water system could result in property
damage.
Check, Test & Start Procedure
NOTICE
Complete the "Water Source Heat Pump Equipment Check, Test
and Start Form" on page 38.
Check As Completed:
†† Open all valves to full open position and turn on
power to the unit.
†† Set thermostat for “Fan Only” operation by selecting
“Off” at the system switch and “On” at the fan switch.
If “Auto” fan operation is selected, the fan will cycle
with the compressor. Check for proper air delivery.
†† Set thermostat to “Cool.” If the thermostat is an
automatic changeover type, simply set the cooling
temperature to the coolest position. On manual
changeover types additionally select “Cool” at the
system switch.
Again, many units have time delays which protect
the compressor(s) against short cycling. After a few
minutes of operation, check the discharge grilles for
cool air delivery. To insure proper water flow, measure
the temperature difference between entering and
leaving water. The temperature differential should be
10°F to 14°F (5°C to 8°C) for units in cooling mode. It
should be approximately 1½ times greater than the
heating mode temperature difference. For example,
if the cooling temperature difference is 15°F (8°C),
the heating temperature difference should have been
10°F (5°C).
Without automatic flow control valves, target a
cooling temperature difference of 10°F to 14°F (5°C
to 8°C). Adjust the combination shutoff/balancing
valve in the return line to a water flow rate which will
result in the 10˚F to 14°F (5°C to 8°C) difference
www.DaikinApplied.com
39
†† Check the elevation and cleanliness of the
condensate line. If the air is too dry for sufficient
dehumidification, slowly pour enough water into the
condensate pan to ensure proper drainage.
†† If the unit does not operate, check the following
points:
a. Is supply voltage to the machine compatible?
b. Is thermostat type appropriate?
c. Is thermostat wiring correct?
†† If the unit operates but stops after a brief period:
a. Is there proper airflow? Check for dirty filter, incorrect fan rotation (3-phase fan motors only), or incorrect ductwork.
b. Is there proper water flow rate within temperature limits? Check water balancing; back
flush unit if dirt-clogged.
†† Check for vibrating refrigerant piping, fan wheels, etc.

Cooling Refrigeration Cycle
When the wall thermostat is calling for COOLING, the reversing valve is energized and directs the flow of the
refrigerant (hot gas) leaving the compressor to the water-to-refrigerant heat exchanger. Here the heat is removed by
the water and the hot gas condenses to become a liquid. The liquid then flows through a thermal expansion valve
(TXV) and then to the air-to-refrigerant heat exchanger coil. The liquid then evaporates becoming a gas, at the same
time absorbing heat and cooling the air passing over the surfaces of the coil. The refrigerant then flows as a low
pressure gas through the reversing valve and back to the suction side of the compressor to complete the cycle.

2. This is not a normal or continuous operating condition. It is assumed that such a start-up is for the purpose of bringing the building space
up to occupancy temperature.
Motorized Isolation Valve
The motorized valve kit is available as a factory-installed
and wired option or may be ordered as a field-installed
accessory.
Wired as shown in Figure 45, the motorized valve will open
on a call for compressor operation.
The motorized isolation valve actuator (ISO) has both a
24V power connection and a 24V end switch connection.
Install the supplied wire harness into plug H8 on the
main control board. Run wires between the ISO actuator
and the supplied wire harness ends.
Connect N.O. & N.C. actuators as shown on the
schematic. The end switch should be wired in series with
the 24V compressor signal wire. Connect the end switch
wires as shown in the schematic. The end switch will
close when the valve is fully open.
Note: For detailed installation instructions for the fieldinstalled motorized valve, refer to IM 1151.

Maintenance
General Maintenance
1. Normal maintenance on all units is generally
limited to filter changes. Units are provided with
permanently lubricated motors and require no oiling
even though oil caps may be provided.
2. Filter changes are required at regular intervals. The
time period between changes will depend upon
the project requirements. Some applications such
as motels produce a lot of lint from carpeting and
linen changes, and will require more frequent filter
changes. Check filters at 60-day intervals for the
first year until experience is acquired. If light cannot
be seen through the filter when held up to sunlight
or a bright light, it should be changed. A more critical
standard may be desirable.
3. The condensate drain pan should be checked
annually and cleaned and flushed as required.
4. Record performance measurements of volts, amps,
and water temperature differences (both heating
and cooling). A comparison of logged data with
start-up and other annual data is useful as an
indicator of general equipment condition.
Charging
Due to the zeotropic nature of R-­410A, it should be
charged as a liquid. In situations where vapor is normally
charged into a system, a valve should be installed in the
charging line to flash the liquid to vapor while charging.
Note: Because a water source heat pump operates
under a wide range of water and air temperatures, the values printed below are to be taken
as suggested pressure and temperatures. All
Daikin water source heat pumps are designed for
commercial use. The units are designed for both
heating and cooling operation and fail safe to
cooling. The reversing valve is energized for the
heating mode of operation

Notes: 1. All information above is based on ISO standard 13256-1
and tested at these conditions.
2. Operating conditions shall be within the limits established in
Table 26, and Table 27 on page 48.
5. Periodic lockouts almost always are caused by
air or water problems. The lockout (shutdown) of
the unit is a normal protective result. Check for
dirt in the water system, water flow rates, water
temperatures, airflow rates (may be a dirty filter),
and air temperatures. If the lockout occurs in the
morning following a return from night setback,
entering air below machine limits may be the cause.
Lubrication
R-410A should be used only with polyester (POE)
oil. The HFC refrigerant components in R-410A will
not be compatible with mineral oil or alkylbenzene
lubricants. R-410A systems will be charged with the
OEM recommended lubricant, ready for use with R-410A.

Damper Maintenance
Greenheck’s dampers are designed to be trouble free
and hassle free under normal operation. Dampers are
to be installed square and straight so as to prevent
binding during operation. The following annual damper
maintenance suggestions will help to insure proper
damper operation and increase the life expectancy of
the damper.
Foreign Matter
Over the course of time, dirt and grime may collect
on damper surfaces. The damper surfaces should be
cleaned to prevent hindrance to airflow.
Moving Parts
Make sure that parts such as linkage, bearings, blades,
etc. that are intended to move freely, can do so.
Lubricating these components can prevent possible
rusting and unnecessary friction increase. Use only a
moli-spray oil or similar graphite based oil as regular
lubricating oil will attract dirt.
Bearings. Synthetic, oil impregnated , and ball bearings
without grease fittings require only minimal grease.
Closure
Remove foreign materials that may be interfering with
blade closure or effective sealing of the blades with
each other or with the frame.
Operation
While operating the damper through its full cycle, check
to see that the blades open and close properly. If there
is a problem, check for loose linkage, especially at the
actuator. Tighten the linkage where required.

Other Installation Considerations
Ductwork and Noise
Flex Duct
Connections
Fiberglass ductboard is a better choice than metal
ductwork for reducing fan noise and is highly
recommended for low sound applications. Where metal
duct is used, sound transmission can be reduced with
flexible duct connections between the fan and the duct.
Sound and Location
The location of these fans must be taken into
consideration before installation. In critical sound
installations, insulated ductwork, flexible duct
connections or placing the fan in a remote section of
ductwork are solutions to meeting the required fan
sound levels.
Filters
The addition of an intake filter is highly recommended
for these fans, even in clean air environments excess
dirt can accumulate on wheels and motors causing
reduced performance and imbalance.

General Maintenance Suggestions
Ceiling exhaust fans require very little maintenance, but
since small problems over time left unchecked could
lead to loss of performance or early motor failure, we do
recommend that the unit be inspected periodically (once
or twice a year).

ENERGY STAR® Models
ENERGY STAR® Certified models include:
SP-A70, 90, 110, 125, 190, 200 and 250,
SP-A50-90-VG and SP-A90-130-VG,
SP-B70, 80 and 90.
The fan motor and wheel should be checked for dust
and dirt accumulations. Dirt buildup can lead to loss of
performance and motor overheating. Cleaning can be
accomplished by brushing off any dust that may have
accumulated. Even filtered units can accumulate buildup and should be checked when cleaning filters.
The motor should be checked for lubrication at this
time. Lubricate only those motors which have an oil hole
provided. A few drops of all purpose oil (SAE 20) will be
sufficient.

Vari-Green® Motor
The Vari-Green Motor is an electronically commutated
(EC) motor that uses AC input power and internally
converts it to a DC power supply which provides an
80% turndown capability and increased energy savings.
Features, Operation and Wiring, and
Troubleshooting
Features
Soft start – All motors
feature soft-start
technology which
eliminates inrush current
at start-up. The motors
will reliably start at any
speed setting.
Overload protection – If the motor becomes
overloaded, it will automatically reduce its speed until it
is no longer overloaded. This means that the motor will
never operate in the “service factor” which is possible
with many AC motors.
Locked rotor protection – If the motor ever encounters
a locked-rotor scenario, the motor will automatically
shut itself down. It will try to restart up to 3 times, and if
after the 3rd time the motor will still not rotate, the motor
will not attempt to start again until power is cycled.
NOTE
When using a clamp meter to measure input amp
draw, the meter must be capable of reading a
non-linear current. Erroneous readings will occur
otherwise.
Thermal protection – The motors have a one-shot fuse
thermal protector. This is meant to protect the motor
from a severe temperature rise. Additionally, the motors
have on-board temperature sensors which will reduce
the speed of the motor should it become too hot. The
fuse is used as a last resort to prevent a fire.
WARNING
To reduce the risk of fire or electric shock, do not use
this motor with any solid-state speed control device.
RPM measurement – The motors have a small shaft
extension on the end of the motor to measure motor
RPM with either a contact or optical tachometer.

These motors will accept a 0-10 VDC control signal for
speed control. From 0-1.9V, the motor will be off, and
will operate in the 2-10V range. 24 VAC/DC power is
also required for operation. The motor will consume
0.7VA at 24 VAC or 25mA at 24 VDC. A factory mounted
transformer is available to supply this voltage.
(See Fig. 1)
Dial on Motor – A small screwdriver can be used to
make the speed adjustment. To increase the speed,
rotate the dial clockwise. To decrease the speed, rotate
the dial counterclockwise. There is no need to connect
the control wires.
0-10 VDC signal – The dial on the motor must be
rotated fully clockwise to achieve the full speed range.
If this is not done, the dial will act as a maximum speed
limiter.
From 0-1.9V, the motor will be off, and will operate in
the 2-10V range. 24 VAC/DC power is also required for
operation. The motor will consume 0.7VA at 24 VAC
or 25mA at 24 VDC. A factory mounted transformer is
available to supply this voltage. (See Fig. 1, page 2)
A low voltage wiring harness is needed to supply the
0-10V signal to the motor. This harness is available from
the factory if conversion is necessary.

Troubleshooting
Operation and Wiring
Motor does not operate
- Potentiometer and 0-10V Input
1. Check all wiring connections to ensure they are
correct and secure.
2. Verify that all voltages are present at the motor,
including 24V and 0-10 VDC, if applicable.
3. Make sure that the fan wheel will rotate freely and
there are no foreign objects in the wheel. If fan wheel
does not rotate freely, disconnect power from the
motor and adjust the wheel or housing until the
wheel can freely rotate. Apply power and the motor
should restart.
4. If motor has both the dial on the motor and 0-10 VDC
control option, control wiring issues can be tested
by disconnecting the control wires from the motor.
The motor should then operate using the dial on the
motor for speed control.
Motor will not reach maximum speed
1. Make sure dial is rotated full clockwise, if applicable.
2. Make sure motor is receiving 10 VDC, if applicable.
3. There are some motor/fan combinations
where the motor may not reach nameplate
RPM. See Max RPM table on page 11 for the
maximum motor speed for your application.
Factory Mounted Transformer (Fig. 1, page 2)
A factory mounted transformer is available to supply
24 VDC power to the motor when the 0-10V signal
is by others. This transformer has the capability to
power a remote device if desired. The power available
to a remote device is 400mA at 24 VDC. If the remote
device is powered by a different source, connect the
analog output to the 0-10V and COM terminals of the
transformer. This will pass the signal through to the
motor.

Features
Speed control These motors can be
controlled by either
a dial on the motor
or a 0-10 VDC signal
for remote control.
Soft start – All motors feature soft-start technology
which eliminates inrush current at start-up. The motors
will reliably start at any speed setting. There will be up
to a 30 second delay between the application of power
and the motor starting. The motor will "rock" back and
forth upon startup as part of its normal operation.
Overload protection – If the motor becomes
overloaded, it will automatically shut itself down. The
maximum programmed motor speeds have been
selected to prevent this from happening in normal
operation.
Locked rotor protection – If the motor encounters a
locked-rotor scenario, it will automatically shut itself
down. It will try to restart up to 3 times, and if after the
3rd time the motor will still not rotate, the motor will not
attempt to start again until power is cycled.
Thermal protection – The motors have an automatic
reset thermal protector. This is meant to protect the
motor from a severe temperature rise.
RPM measurement – The motor RPM can be
measured by removing the cooling fan cover and using
a contact or optical tachometer. Be sure to replace the
cooling fan cover when finished.
Reversible rotation – The motor direction has been
pre-set at the factory for the rotation of the fan but can
be reversed if necessary.
Operation and Wiring
These motors can be controlled by either a dial on the
motor or a 0-10 VDC signal for remote control. The
motor will be supplied from the factory with the correct
accessory depending on what was ordered.
Dial on Motor - Turn the dial with your fingers to adjust.
To increase the speed, rotate the dial clockwise. To
decrease the speed, rotate the dial counterclockwise.
Turning the dial full Counter Clock Wise will turn the
motor off.
0-10 VDC Signal - From 0-1.9V, the motor will be off,
and will operate in the 2-10V range. This motor does not
require 24V power for operation.

Wiring
1. All high and low voltage wiring connections are made
inside the motor control box at the factory. Normally,
there is no reason to enter the control box of the
motor. If there is a need to enter the control box,
disconnect power and wait at least five minutes to
allow the capacitors to discharge.
2. The motors are factory wired for the ordered voltage.
If the factory wired voltage does not match the
desired voltage, the voltage can be changed, with
exception of the 2HP motor (310420), which is
208‑240V only.
115V: Connect 115 VAC to L1, connect Neutral to N.
The L2 terminal remains empty. Connect ground to
grounding stud.
Dial on Motor - the dial
is factory-wired into the
low voltage terminal block
inside the control box.
The wires are connected
as shown.

Troubleshooting
These motors have a diagnostic red LED on the circuit
board inside the control box, or on the exterior of the
control box, that will be solid (not flashing) when power
is applied to the motor and the motor is operating
normally. The LED may be solid even if the motor is not

may be commanded to be off with a 0-1.9V VDC signal.
1. If external LED is not present, to view the status of
the LED the control box cover must be removed
while power is applied to the motor. If the control
box cover is removed while power is applied,
extreme care must be taken not to touch any of the
components inside the box.
2. If a fault occurs, the LED will blink a specific number
of times to identify the fault that has occurred. The
fault indications are as follows:

Remote Dial
Installation Overview: The remote dial is provided
with the fan, shipped loose for remote installation.
It also includes a factory mounted 24 VDC transformer.
1. Disconnect power to the fan.
2. Identify where the remote dial will be mounted.
3. Mount a standard single-gang 2x4 junction box.
4. Run a 3-wire control cable from the remote dial to
the fan motor compartment. The maximum distance
from the fan to the remote dial is 100 feet. If a greater
distance is required, signal loss may occur and cause
the fan to operate erratically.

3. When the LED is blinking, it will consecutively blink
from 2 to 9 times, followed by a pause, and repeat
the blink sequence. It is best to count the number
of flashes 2 or 3 times to ensure accuracy.
4. Under most fault conditions the motor will
automatically restart. If a motor overload fault occurs
more than 10 times in one hour, the motor will shut
down and require a power cycle to reset.
5. If the fault persists, consult the factory.
Remote Dial with Min/Max Setting
Remote dials (P/N 385803) are capable of setting
minimum and maximum voltage limits. Setting voltage
limits will require a multi-meter. To set a voltage span:
1. Install and wire remote dial as previously instructed.
2. Install multi-meter probes into the red (0-10v) and
black (ground) connectors.
3. To set maximum voltage limit, apply power to the
motor, transformer and remote dial. With remote dial
set to zero (0), hold the Upper Limit button down and
turn the dial until the desired voltage is displayed on
your multi-meter. Release button to save max voltage
setting.
1. Verify the motor is wired for the correct voltage.
4. To set lower voltage, turn remote dial back to zero
(0). Hold down Lower Limit button while turning
dial to desired voltage on your multi-meter. Release
button to set minimum voltage limit.
2. Verify that the dial on the motor is properly
connected to the control board - or - verify that
the 0-10 VDC wires are properly connected to the
control board.
5. To reset to default (0-10v) limits, hold both Upper
and Lower limit buttons down simultaneously until
the LED indicator lights up. Then release buttons and
default levels will be restored.
Motor does not operate
3. Verify that the Status LED is solid red.
4. Verify that a jumper is in place between terminals
9 and 10. The motor will not run without this jumper
in place.
NOTE: Upper voltage limit must be set prior to
setting lower voltage limit. Upper and lower limits
can only be within 0.5v of each other.
5. Verify that the two yellow wires coming from the
motor are in place on terminals 5 and 6.

Two Speed Control
Troubleshooting - Two Speed Control
Installation Overview: The two speed control is factory
mounted to the fan and may be set to provide any
two speeds the application requires. It also includes a
24 VDC transformer. A green LED will be illuminated
when the 2-speed control is powered.
1. Check all wiring connections to ensure they are
correct and secure.
1. There are two methods of toggling between speed A
and speed B:
a. Dry contact input - this utilizes an external
switching device such as a relay or SPDT switch
to toggle between the two speeds.
• Connect terminal “A” to “COM” for speed A.
• Connect terminal “B” to “COM” for speed B.
If no contact is made between either terminal the
motor will be off.
2. Verify AC line voltage is present at the motor and
2-speed control.
3. Verify 24 `VDC is present at the 24V and COM
terminals of the "Motor" terminal block.
4. Measure DC voltage between the 0-10V and COM
terminals of the "Motor" terminal block. This voltage
should match the dial position of the active dial.
a. If using dry contact input - ensure contact closure
is connecting the proper terminals.
b. If using AC digital input - disconnect connector
from 2-speed control and measure voltage
between L1 and Neutral or L2 and Neutral.
b. AC digital input - this input allows an AC voltage
signal to be fed directly into the 2-speed control
to change speeds.
• Send 115-230V AC to L1 OR L2 for speed B.
• Send 115-230V AC to L1 AND L2 for speed A.
If no voltage is applied to either terminal, the
motor will be off.
c. DO NOT CONNECT BOTH DRY CONTACT AND
DIGITAL INPUTS SIMULTANEOUSLY.
2. To test fan operation before the external control
devices are installed, a jumper wire can be
connected between the COM and A or B terminal on
the dry contact input for fan operation.

Section 1
Receiving Inspection
After unpacking the terminal, check it for shipping damage. If any shipping
damage is found, report it immediately to the delivering carrier. Store units
in a clean, dry location prior to installation.
Also, inspect damper rotation of the unit by rotating the damper by hand
to check for free movement, and ensure there is no damage or binding of
the damper. If controls are connected to the damper, release the manual
clutch (most controls are equipped with this) and rotate the damper by
hand. If there is any restriction to the rotation of the damper, contact your
Titus rep and inform them of this issue.
caution
Do not use the flow sensor, connecting tubing, or damper
shaft linkage as a handle to lift or move assembly. Damage
to the flow sensor or controls may result.
Supporting the Assembly
The diameter of the inlet duct “D” in inches must be equal to the listed size
of the terminal; e.g. a duct that actually measures 8 inches must be fitted
to a size 8 terminal. The inlet collar of the terminal is made 1/8 inch smaller
than listed size in order to fit inside the duct (see Figure 1).
note
Do not insert duct work inside the inlet collar of the
assembly.Inlet duct should be installed in accordance
with SMACNA guidelines.
The outlet end of the terminal is designed for use with slip and drive
duct connections. A rectangular duct the size of the terminal outlet
should be attached.
Inspect the Aerocross inlet flow sensor for shipping damage, and
ensure that the high (green) and low (red) tubes are attached. Provide
at least 1½times the inlet duct diameter of straight duct for optimum
control accuracy. For more information on our Aerocross, see the
Aerocross Flow Sensor Application Guide.
AssemblyMany basic single duct terminals are
light enough to be supported by the duct work
itself. Where heavier accessory modules, such as
DDC controls, coils, attenuators, or multiple outlets
are included, the terminal should be supported
directly. Straps screwed directly into the side of the
terminal, threaded rod through the optional hanger
brackets (see Figure 1), or the method prescribed
for the rectangular duct on the job specifications
may be used.
Important: If equipped with pneumatic controls,
the terminal must be mounted right side up. It must
be level within+ or -10 degrees of horizontal, both
parallel to the air flow and at the right angle of air
flow. The control side of the terminal is labeled with
an arrow indicating UP. The first letter of the model
number (P) indicates pneumatic controls. Most
electronic units (A-analog controls and D-digital
controls) can be installed in any orientation. Check
with the local TITUS representative for verification.
Duct Connections
Slip each inlet duct over the inlet collar of the terminal.
Fasten and seal the connection by the method
prescribed by the job specification.

Section 1 - General Information
Field Wiring
All field wiring must comply with the local codes and with the National
Electrical Code (ANSI/NFPA 70-1981). Electrical, control and piping
diagrams are shown on the exterior labeling or on the diagram on the
inside of control enclosure cover. All electric heaters if provided by TITUS
are balanced by kW per stage. The installing electrician should rotate these
heater stages by phase in order to help balance the building electric load.
Control Start-up, Operation
Detailed information regarding power, accessory and communications
connections, start-up and operating procedures for the controls
provided by TITUS are available from your local TITUS representative.
For specific information on controls by other manufacturers, contact that
manufacturer’s local branch or dealer.
Important: Units with digital controllers may incorporate specific
communication addresses based on Building Management Systems
Architecture, and original engineering drawings. Installing the
terminal in a different location than noted on unit label may result in
excessive start-up labor.
