AIR-COOLED DIRECT EXPANSION UNIT - VERSION
AX
All models have a single refrigerant circuit, and in some cases two
circuits.
See the DIGIT on the previous page.
The compressor pumps the hot refrigerant gas into the outdoor
condenser.
The liquid refrigerant then flows to a liquid receiver installed in
the indoor unit, to ensure a constant flow of refrigerant to the
thermostatic valve and subsequently the evaporator.
Here the liquid refrigerant absorbs the heat from the environment and changes state, becoming a gas, then returning to the
compressor: the cycle is then repeated.
To ensure the correct discharge pressure of the refrigerant, we
suggest to select a unit provided with fan speed control.
Valves for isolating the refrigerant circuit are supplied as standard
to assist the routine maintenance operations.
The Scroll compressor is fitted with a non-return valve to prevent
the migration of liquid from the outdoor condenser in the summer, and unwanted flows of refrigerant during start-up.
A second non-return valve, on the liquid line to the outlet of the
condenser, to be fitted by the installer, is recommended during
operation in winter, to prevent the migration of the refrigerant
charge from the liquid receiver to the outdoor condenser, with
consequent low pressure alarms. The units are provided, as standard, with centrifugal fans.
Air-cooled condenser, outdoor installation
The indoor unit can be connected to different types of outdoor
condensers, standard or low noise versions, with special treatments on the coils.
For the corresponding information refer to the manual on outdoor air-cooled condensers.
Note 1: the outdoor units and condensers are supplied separately
Note 2: the indoor unit is delivered charged with nitrogen at
near atmospheric pressure. The outdoor condenser, on the other
hand, is supplied pressurised with dry air (around 3 bar.)
Note 3: the customer is considered responsible for making the
correct connections between the indoor and outdoor unit, as
clearly indicated in the Installation manual, and for ensuring the
gas and oil charges, where necessary.

WATER-COOLED DIRECT EXPANSION UNIT VERSION AW
All models have a single refrigerant circuit, and in some cases two
circuits. See the DIGIT on the previous page.
The compressor pumps the hot refrigerant gas into the indoor
condenser made from braze welded steel plates. The liquid refrigerant then flows to a liquid receiver installed in the indoor unit, to
ensure a constant flow of refrigerant to the thermostatic valve
and subsequently the evaporator. Here the liquid refrigerant
absorbs the heat from the environment and changes state,
becoming a gas, then returning to the compressor: the cycle is
then repeated. To ensure the correct discharge pressure of the
refrigerant, we suggest to select a unit provided with pressostatci
valve. Remember that circulation pump is NOT selected, nor provided from Climaveneta. The units are provided, as standard, with
centrifugal fans.
Water condenser
The units are fitted with an internal braze welded steel plate heat
exchanger.
During installation, a pressure control valve should be fitted (available in the price list) to manage the condensing pressure.
(See the User and Maintenance Manual)
This circuit works with primary water or with a closed circuit
connected to an external Dry Cooler or an evaporative tower.
For “closed” circuits, the water should be mixed with antifreeze
to prevent frost during the winter, with consequent damage to
the systems: see the installation manual to calculate the required
percentage of antifreeze fluid.
The Dry Coolers are supplied as an accessory (see the price list),
while the antifreeze fluid and fluid circulating pump are generally
supplied by other companies.
For “open” circuits, mechanical filters are required to protect
against impurities and prevent the braze welded plate heat
exchanger from blocking.
To reduce energy consumption (pump), a valve should be fitted to
close the circuit when the indoor unit is off.
Note 1: the water-cooled indoor units (AW) come with the
refrigerant circuit completely charged and tested in the factory
before being delivered.

FREECOOLING UNIT – VERSION AF
All models have a single refrigerant circuit, and in some cases two
circuits. See the DIGIT on the previous page.
Each refrigerant circuit includes the compressor and a pressurebalanced thermostatic valve (or electronic valve) to ensure stable
superheat temperatures. A liquid indicator is fitted before the
thermostatic valve to display the gas charge.
A dewatering filter is installed on the liquid line to keep the circuit clean and free of dirt.
The refrigerant circuit is also fitted with high and low pressure
switches. The low pressure switch has automatic reset, while for
safety reasons the high pressure switch has manual reset. Remember that circulation pump is NOT selected, nor provided from
Climaveneta. The AF units are provided, as standard, with radial
fans EC.
Condenser
Each unit is fitted with one (for single circuit units) or two (two
circuit units) condensers made from braze welded stainless steel
heat exchangers. Each condenser is fitted with an HP8 automatic
valve to control the condensing phase. In addition, the condensers
are oversized in order to limit pressure drop (and minimise the
power input of the circulating pumps).
The units generally work via closed circuits with dry coolers
cooled by the outside air. To prevent the formation of frost, the
fluid used inside the closed circuit should always contain a percentage of glycol, as indicated in this manual, based on the average
minimum temperature reached in the place of installation in the
coldest periods.
The cooling fluid must be circulated by pumps (not supplied as
standard). Suitably-sized dry coolers are available as options.
Water circuit
The unit is fitted with a 3-way modulating valve to control the
flow of cooling fluid to the indoor exchanger on the freecooling
units. The opening and closing signal is generated and completely
managed by the electronic controller on the air-conditioner, so as
to maintain the desired conditions and ensure maximum energy
saving.

DUAL FLUID UNITS – VERSION AD (air-cooled)
& AT (water-cooled)
All models have a single refrigerant circuit, and in some cases two
circuits.
See the DIGIT on the previous page. Each refrigerant circuit
includes the compressor and a pressure-balanced thermostatic
valve (or electronic valve) to ensure stable superheat temperatures. A liquid indicator is fitted before the thermostatic valve to
display the gas charge. A dewatering filter is installed on the liquid
line to keep the circuit clean and free of dirt.
The refrigerant circuit is also fitted with high and low pressure
switches. The low pressure switch has automatic reset, while for
safety reasons the high pressure switch has manual reset. The AD
and AT units are provided, as standard, with radial fans EC.
Version AD (air-cooled)
A non-return valve should be installed on the liquid line between
the indoor unit and the outdoor unit by the installer.
The units are supplied separately from the outdoor condenser
and are pre-charged with nitrogen. The customer is responsible
for the connection between the two indoor and outdoor units
and for the emptying and charging operations. For these operations, follow the instructions provided in the installation manual.
Outdoor air-cooled condenser
The air-cooled condenser should be selected from the models
available in the vast range provided by the manufacturer
Water circuit
The unit is fitted with a 3-way modulating valve to control the
flow of cooling fluid to the indoor exchanger so as to maintain
the desired conditions.
In the DUAL FLUID units, the two circuits, direct expansion DX
and chilled water CW, never work at the same time.The direct
expansion circuit DX is used as backup to the chilled water circuit CW. Activation set points for the two circuits are available
and are described in the User Terminal manual.

ACCESSING THE MAIN COMPONENTS
I
A
The air-conditioner is accessible from all sides by removing the
various panels.
The front and/or side panels are opened in 2 different ways:
FRONT PANELS
All the front panels are hinged and fitted with locking latches and
seal.
All the front panels are opened and closed using a tool (typically a
screwdriver) to open and close the latches.
Once the latches have been opened, the front panels can be
swung open and then removed vertically to simplify the service
operations on the air-conditioner, especially where there is little
space available.
Opening the front panels provides access to all the components
in the air-conditioner involved in routine maintenance.
The number of front panels depends on the capacity of the airconditioner.
SIDE PANELS
All the side panels are accessible and removable.
Nonetheless, these do not need to be removed for routine maintenance operations. This means that, if necessary, a series of units
can be installed next to each other.
The side panels are fastened by screws.
These are accessible directly on the side panel by removing the
black plastic caps.
electrical panel
BACK PANELS
Fastened by normal self-tapping screws, these are not accessible
as when installed the back of the unit is against the wall

INSIDE PANELS
The compartment that contains the fans and the heaters is protected and insulated by a metal plate.
This is for safety reasons, so as to not have to shut the unit down
during normal maintenance operations.
WARNING: before restarting the air-conditioner, always
check that all the panels have been correctly replaced.

POSITIONING THE AIR-CONDITIONER
The air-conditioner can rest directly on the floor, perfectly level,
with a maximum difference in height of 5 mm between the ends
of the base: incorrect levelling may cause the condensate to leak
from the collection pan.
I
A
P1
L1
WARNING: the air-conditioner must be installed indoors
and in non-aggressive environments. Apply an elastic gasket
around the perimeter of the base to prevent the transmission of noise and vibrations.
SUPPORT FRAME (optional accessory)
A support frame is recommended:
- to allow the air-conditioner to be installed before assembling
the raised floor;
- to totally dampen any mechanical vibrations;
- to assist the laying of pipes and cables.
The support frame is available as an accessory and is adjustable in
height, indicated in the figure by the distance X, between 200 and
600 mm.
To prevent the transmission of noise and vibrations, an elastic gasket, at least 5 mm thick, should be inserted between the panels of
the raised floor and the frame, which must also be insulated from
the metallic structure of the floor.

Access is from the front only for all models.
This feature ensures easy access to all the main components in
the unit for installation and periodical maintenance.
Thanks to this feature, the units can be installed next to one
another, or alternatively fitted in racks.
To ensure easy maintenance, a space of at least 600 mm must be
left in front of the air-conditioner, as shown in the figure.
Make sure that the air intake and outlet are never
blocked, even partially.

OPTIONAL BASE MOULDING (OVER UNITS)
The "OVER" units are designed for the connections to pass
through the base of the unit; nonetheless, if there is no raised
floor (units with intake from the rear or front), to simplify the
connection of the pipes and cables, a base moulding must
be used.
The base moulding, available as an accessory, is epoxy-polyester
powder painted, in the same colour as the external panels on the
air-conditioner, measures 200 mm in height and is fitted with an
inspection panel at the front fastened by two latches tightened
1/4 of a turn.
The inside walls are lined with soundproofing material.
On the right- and left-hand sides of the base moulding are six
pre-cut sections for passing the cables and pipes;
The moulding must be fastened to the air-conditioner using the
M6 threaded inserts already arranged on the base.
For the OVER units with intake from the bottom, base mouldings
are available with a height of 500 mm.
In this case too, the air-conditioner must be screwed to the base
moulding during the positioning phase.

AIR DISTRIBUTION, UNDER UNITS (UNDER UNITS)
In the units with air outlet from the bottom, the following details
must be ensured to allow for sufficient air flow-rate:
a) connection opening between the unit and the raised
floor; make a hole in the raised floor and position the air-conditioner over the centre of the hole: the air outlet opening
must not be blocked, even partially, by parts of panels, beams,
pipes or other objects; insert an elastic gasket around the
perimeter of the base to prevent the transmission of noise and
vibrations;
b) free air flow along the cavity of the raised floor; the
duct represented by the underfloor space must be sufficiently
high (at least 200-250 mm of free space, net of the panels and
the beams of the raised floor) and free of obstructions, especially near the air-conditioner;
c) grills and air distribution openings in the room; the air
exits the underfloor space through openings or grills, the position and surface area of which must be proportional to the
layout of the thermal load of the environment.
I
A
For units with air outlet from the bottom, the recommended air
outlet speed from the raised floor is between 1 and 2.5 m/s; consequently, the cross-section of the grills should be sized based on
this value
The total outflow area (sum of the areas of the openings and net
space of the grills) required for each model must be calculated by
dividing the total air flow-rate (in m3/s) by the required outlet
speed (in m/s).
WARNING: the air outlet must be completely free, as an
insufficient air outflow air will reduce the flow-rate, the performance of the air-conditioner and may affect reliability.

WATER CONNECTIONS
For all the water connections (with the exception of the
condensate drain), the following are recommended:
- flexible connections to avoid transmitting vibrations and
allow small movements of the air-conditioner;
- joints in three pieces, near the fittings, to simplify the
removal of the unit;
- on-off valves to disconnect the unit from the water circuit: where possible use ball valves with full opening to
minimise pressure drop.
(For AW-AT-AF models) check that the cross-section of
the chilled water pipes and the characteristics of the circulating pump are suitable: an insufficient water flow-rate
affects the performance of the air-conditioner.
Check that the water inlet and outlet connections are correct. Insulate all the chilled water pipes with closed cell
material (e.g.: Armaflex or equivalent), to prevent condensation; the insulation must allow access to the valves and
the three-piece joints.
I
A
(For AW-AT-AFmodels) check that the water circuit has
been filled with an antifreeze mixture containing the right
percentage of ethylene glycol.
To select the pipeline refer to "Pressure Drops on
stainless steel pipes"
U
CONNECTION TO BRAZED PLATE CONDENSER AW-AT-AF
AW-AT-AF water-cooled units
The condenser must be connected to the cooling water circuit,
making sure that the water inlet and outlet connections are correct.
If the water temperature falls below the dew point of the conditioned air, insulate the pipes with closed cell material (e.g.:
Armaflex or equivalent) to prevent condensation; the insulation
must allow access to the valves and the three-piece joints.
I
A
Seal the holes where the pipes pass through the base of the airconditioner to avoid the bypass of air.
N.B.: the water system of the unit is PN16

OIL SEPARATOR
I
A
In the installation of air cooled units (AX-AD) with remote condenser, if the refrigerant pipeline are more than 30mt is recommended to
install an oil separator on site, in order to avoid that the oil goes away with the refrigerant causing compressor damages
Finally, the use of an oil separator leads to:
• a longer life of the compressor;
• a better performance of the whole system with consequent energy saving, due the high coefficient of condenser and evaporator performance by almost completely removing oil deposits from their exchange surfaces;
• a quieter operation by reducing pulsations.
The oil separator have to be selected considering the following parameters:
• power cooling of refrigerant system
• refrigerant fluid type
• the inlet diameter of oil separator have to be equal to the dicharge gas diameter of compressor

* refered to evaporating temperature +5°C and condensing temperature 40°C
The oil separators have to be installed in the discharge line between the compressor and the condenser mounted securely in a vertical
position and reasonably close to the compressor.
Oil separator performs best when operating at or near the compressor discharge temperature. In location the oil separator, choose a position to avoid, as far as possible, chilling of the shell, which may result in condensing of liquid within the separator. If this is not possible, it is
advisable to supply the separator with the insulation or strap heater to prevent the refrigerant in the system from condensing in the shell.
Acting as the lay out of refrigerating system, the return line may be run from the oil fitting to the suction line upstream the compressor.
A sight glass may be installed in the oil line, in a position that oil is flowing through the tube, to check the correct working of the oil separator. Oil separators must be always pre-charged before its use, as described on the table, with the same oil of the compressor

CONDENSATE DRAIN
The condensate is removed from the pan located underneath the
coil through a hose with drain trap, already fitted in the unit; the
end of the hose should be connected to the sewerage system in
the building via a rubber or plastic hose with an inside diameter
of 20 mm.
A
If the air-conditioner is fitted with a humidifier, the condensate is
drained from the humidifier pan, excluding Over units (see the
following paragraph).
During installation, pour water into the condensate collection pan
so as to fill the drain trap inside the unit with water.
U
ELECTRICAL CONNECTIONS
Correct electrical connection, performed in a workmanlike manner and in compliance with the standards in force, is important
for the prevention of accidents and the good and long-lasting
operation of the air-conditioner.

ACCESS TO THE ELECTRICAL PANEL AND CABLE
INLETS
Before performing any work on the electrical parts, make sure
that there is no live voltage and that the disconnecting switch is
open (position “O”);
The power section of the electrical panel is protected by a plastic
screen; to remove the screen, open the main switch and remove
the fastening screws.

CONNECTION TO THE MAINS - CROSS-SECTION OF
THE CABLES - PROTECTION DEVICES
- Check that the mains voltage corresponds to the rated values for the unit (voltage, no. of phases, frequency) shown on the
electrical panel.
The power supply voltage must be between ± 10% of the rated
value: operation at voltages outside of these limits may void the
warranty.
- Fasten the ends of the power cable to the terminals on the
main switch inside the electrical panel; fully tighten the screws.
Connect the yellow-green earth wire to the special terminal
marked 'PE'.

ACCESS TO THE BOARD
To access the board, open the front panel and the thermoformed
cover on the electrical panel.
The electronic components are sensitive to discharges of static
electricity from the human body.
Touch an earthed object before handling any electronic component.

U
MINIMUM CROSS-SECTION OF THE POWER CABLES
The cross-section of the power cable must be chosen according
to the length of the cable and the type of installation, based on
the maximum current input of the air-conditioner and so as to
prevent excessive voltage drops (the power supply voltage must
be between ± 10% of the rated value).
The following table shows the minimum recommended cross-sections for the power cables.
I

ELECTRICAL CONNECTION OF THE OUTDOOR AIR-COOLED
CONDENSER BRC AND/OR THE OUTDOOR DRY COOLER BDC
It must be stressed that both the standard air-cooled condensers
and dry coolers supplied by the manufacturer are not fitted as
standard with the condenser fan speed controller, and are only
electrically connected to the disconnect switch for local maintenance operations (for further details, see the manual on the outdoor air-cooled condensers and dry coolers).
Therefore, both of these outdoor units can be powered directly
via the disconnect switch with primary voltage, however this
means their operation is not controlled.
If the indoor units used are the ACCURATE in MODULATING
version, complete with condenser fan speed controller, the outdoor air-cooled condenser and/or dry cooler can be connected/powered directly from the panel on the indoor unit (the connection cable is not supplied by the manufacturer).

U
A
The instructions on the connection and the size of the power
cables are provided by the manufacturer on the wiring diagram
on the indoor unit. For both single and dual circuit models, just
one connection/power cable is required between the indoor and
outdoor unit. The voltage delivered will be modulated by the condenser control unit installed on the indoor unit, based on the current requirements of the system.
This ensures optimum operating conditions.
The condenser control unit is also featured as standard on the
versions of the indoor units for low outside temperatures (45°C).
There are two types of speed controllers used, based on the size
in question. Both are positioned and installed on the indoor unit
refrigerant circuit.

VACUUM AND CHARGE
The refrigerant circuits of the water-cooled chillers and air-conditioners are already charged with refrigerant, either R407C or
R410A (check the rating plate on the unit and the compressors
to see which type of refrigerant is used).
The air-cooled air-conditioners (AX-AD) and the BRC units that
A
require refrigerant connections to other units are pre-charged
with nitrogen (or dry air) to prevent moisture from entering the
circuit; in this case, the refrigerant charge must be completed by
the installer, following the instructions shown in this paragraph.
Refrigerant (*)
R407C / R410A (POE)
I
Type of oil
Mobil EAL Arctic 22 CC
ICI EMKARATE RL 32S CF
R407C / R410A
Open any valves in the unit or in the system to ensure that all the components are involved in the emptying operation;
Connect a high efficiency vacuum pump to the Schrader fittings or to the 1/4" SAE fittings on the compressor suction and discharge side;
Connect a cylinder of refrigerant to the charge fittings.
Empty the lines, ensuring an absolute pressure of less than 10 Pa (0.07 mm Hg) so as to remove the air and any traces of moisture
The circuit should be emptied slowly and maintained for an extended period, rather than performed too quickly.
Wait a "go up time" of 100 seconds and verify that the pressure does not exceed over 200 Pa absolute.
In general, if there is the chance of significant moisture content in the circuit or for very large systems, the vacuum must be “broken” with
nitrogen dioxide and then repeat the emptying operations as described.
Break the vacuum by pre-charging from the cylinder of refrigerant.
After having started the compressor, complete the charge slowly, until the pressure stabilises in the lines and the gas bubbles disappear
from the flow indicator;
The charge must be checked at the environmental design conditions and with a discharge pressure of around 18 bar (equal to a dew point of 48°C
and boiling point of 43°C); for units with on-off condenser control, partially close the intake to stop the condenser fan from repeatedly starting-stopping.
Make sure that the subcooling of the liquid at the thermostatic valve intake is between 3 and 5°C less than the condensing temperature read on the
pressure gauge and that the superheating of the vapour at the evaporator outlet is around 5 °C.
(*) recommended with COPELAND compressors.
If a circuit already charged with refrigerant needs to be emptied, the first operation required is the removal of the refrigerant from the circuit using a special appliance with dry compressor for recovering the refrigerant. If available, also switch on the sump heaters during the
emptying operation.
COMMISSIONING PROCEDURE
Arm the cutout in the auxiliary circuits;
Arm all the cutouts on the electrical panel;
Power up the air-conditioner electrical panel and close the main
disconnecting switch on the unit (position 'I');
Check that the control board is powered; Check that both the
LEDs relating to the phase sequence relay (RSF) are on; the yellow LED indicates power, the green LED indicates that the
sequence of phases is correct.
If the green LED is off, disconnect power supply from the units,
reverse two phases of the power cable and restart the commissioning procedure. (In the units with sump heaters)
After having powered up the air-conditioner, wait at least 12
hours before starting so as to suitably heat the oil in the compressors. During extended shutdown there may be spontaneous
migration of refrigerant to the compressor sump, which at the
start may cause the oil to foam and consequent damage due to
insufficient lubrication.
As a result, do not disconnect power during weekly pauses;
Open the on-off valves in the refrigerant circuits and check that
the air-cooled remote condensers are connected (air-cooled
models); Check that the external radiators are connected and
make sure there is water flow for cooling (water-cooled models);
Check that the sections of corrugated pipe with the function of
drain trap (both inside and outside of the air-conditioner) have
been filled with water during installation.

OPERATION AND CONTROL
I
A
WATER-COOLED UNITS
Water in an open circuit
If the temperature of the cooling water is not controlled and may fall
below 25°C, a pressure control valve is required (available as an
accessory) for each condenser; in this case, the supply pressure must
not be less than 200 kPa (2 bar).
IMPORTANT: do not use water cooled using an evaporative tower, as
the condensers will rapidly become fouled by lime scale.
Water in a closed circuit
The condensers on the units are supplied with water pumped in a
closed circuit and cooled by external radiators; check that the crosssection of the pipes and that the characteristics of the circulating
pump are suitable: an insufficient water flow-rate affects the performance of the air-conditioner. The temperature of the cooling water
must be controlled so as to not fall below 25°C, preferably according
to the diagram shown in the figure.
25 °C
A
B
IMPORTANT: the cooling water must contain a percentage of
ethylene glycol (passivated and consequently non-corrosive)
according to the minimum expected outside temperature.
In the Energy Saving models, the use of glycol is always required.
CALIBRATING THE THERMOSTATIC VALVE
(air-cooled models)
The thermostatic valve is calibrated using the adjustment screw
shown in the figure; in the water-cooled models, the correct calibration is already performed in the factory.
• Check that the subcooling of the liquid at the condenser outlet
is around 3-5°C;
• Check that the thermostatic valve superheating value is correct (around 5 °C);
• Check that the valve sensor bulb is correctly positioned,
secured and insulated.
If the superheating is above the value indicated previously, open
the valve further; if it is lower, close the valve further.

TIGHTENING THE DRIVE BELTS
In the versions from frame 3 upwards, the fans in the standard
version are centrifugal with forward blades and belt drive.
A required periodical maintenance operation (at least once a
year) involves having specialist personnel check the correct tension of the belt.
To check the tension, proceed as follows: apply a perpendicular
force of around 20 N (2 kg) to the centre of the belt (between
the 2 pulleys).
The belt must have a deformation of around 6-8 mm.
If this is not the case, adjust the tension using the worm screw
located on the slide that supports the electric motor.
Overly tight belts will cause unbalanced transmission.
Too loose belts, on the other hand, will cause the motor to overheat and excessive power consumption.

CALIBRATING THE PRESSURE CONTROL VALVE
(option available for water-cooled models)
The pressure control valve, by managing the flow of water, prevents the condensing pressure from lowering excessively and, at
the same time, saves water consumption.
If necessary, calibrate the pressure control valve using the adjustment knob (the pressure is increased when turning clockwise)
until the condensing pressure stabilises at the recommended value of 18 bar (equivalent to a satured temperature of around 45°C
when using di R407C) and 27 bar (equivalent to a satured temperature of around 45°C when using di R410A), measured using a
pressure gauge connected to the pressure test point on the outlet valve.
To calibrate the pressure switch:
• simulate a fault in the fan system (stop the fan - if there is just
one - or one of the fans on the unit) and check that the pressure switch is activated;

ELECTRIC HEATERS
The overall power of the electric heaters is divided into a number
of elements, each with a power of 2/3/4 kW.
The colour of the wires on each element has the following meaning:
• BLACK wire = low power element (0.7/1/1.3 kW);
• WHITE wire = high power element (1.3/2/2.7 kW);
• RED wire = common.
The wires for each element are connected to contactors M5 and
KM6 on the electrical panel so as to balance the load between
the phases and create three stages of power (see the wiring diagrams on the unit).
If having to replace the electric heaters, disconnect power to the
air-conditioner and wait until the heating elements have cooled
down. After having replaced the heaters, make sure the earth is
connected.

ACCURATE AX - AW - AD - AT - AF
HUMIDIFIER OPERATING PRINCIPLE
In the immersed electrode humidifier, the current that runs
between the electrodes, through the water contained in the boiler cylinder, generates the heat required to boil the water.
By controlling the level of the water and the concentration of
salts inside the steam cylinder (6) using the fill (7) and drain (8)
solenoid valves, the amount of current delivered can be regulated,
and measured using a current transformer (2).
When steam production is required, the humidifier contactor CU
closes (see the wiring diagram) so as to supply power to the
immersed electrodes.
When the current falls below the set value due to the lowering of
the water level, the fill valve (7) is opened.
The drain valve (8) is activated cyclically, depending on the characteristics of the supply water, so as to maintain the optimum salt
concentration inside the cylinder (6).
The only periodical maintenance operations required are the
inspection and cleaning of the parts in the steam production unit.
The operations indicated below should be performed annually,
preferably before shutting down the unit in summer.
STEAM CYLINDER
The steam cylinder requires periodical cleaning to remove the
scale deposits that form on the surface of the electrodes and the
flakes that deposit on the filter at the base of the cylinder.
To remove the cylinder, proceed as follows:
• completely drain the water from the boiler; to do this, see the
paragraph “MANUAL CONTROL” in the EVOLUZIONE controller instruction manual;
• disconnect the power supply by opening the main switch on the
electrical panel;
• remove, from the top of the cylinder, the hose that carries the
steam to the distributor;
• disconnect the power connections by unscrewing the knobs on
the cable ends and remove the plugs from the level electrodes;
• release the strap that secures the cylinder to the unit;
• slide the cylinder out upwards.
The steam cylinder can be reused a number of times after cleaning the electrodes: if, however, the wear on the grills of electrodes
is such that these cannot be regenerated, they must be replaced.
The only spare part is the complete cylinder body (with filter
included).
FILL AND DRAIN ASSEMBLIES
To ensure the correct operation of the humidifier, the supply/fill
and drain assemblies need to be inspected periodically.
Proceed as follows:
- completely drain the water from the boiler using the MANUAL
CONTROLS on the controller A1;
- disconnect the power supply by opening the main switch on the
electrical panel;
- remove the fill pipe from the 3/4 GAS fitting on the fill solenoid
valve;
- remove and clean the filter located inside the solenoid valve fitting;
- dismantle the drain assembly (shown in Figure 13), clean the
pipes and remove any flakes of scale from the cup-drain trap.

HUMIDIFIER AND CONDENSATE DRAIN
Underneath the drain solenoid valve on the steam production
unit is an attachment for draining the water.
This is already fitted with a hose coupling for connecting the hose
running to the sewerage system in the building.
A rubber or plastic hose should be used, resistant to 100°C, with
an inside diameter of 32 mm.
Fit a trap in the section of the hose outside of the unit to avoid
bad odours and to prevent water from overflowing from the
humidifier pan.
During installation, pour water into the condensate collection pan
and the humidifier pan, so as to fill the drain traps outside and
inside the unit with water.
Downstream of the drain trap ensure a minimum slope of 1%.

MAINTENANCE
Every components replacement (compressor, safety pressostat, liquid receiver, ecc.) have to consider the main component list enclosed in the unit.
This section, aimed above all for the end user, is extremely important for the correct operation of the appliance.
Just a few operations completed scrupulously and regularly will
avoid serious damage to the components. Only authorized and
specialist personnel can operate into the units.
The maintenance operations can be summarised as follows:
- Clean the air filter.
- Check and clean the condenser coils
- Check the water-cooled condensers for fouling.
- Check and clean the drains.
- Check the drive belts.
- Check the humidification system.
- General examination of the overall operation of the appliance.
- Visual check of the condition of the pressurised containers.
Cleaning the air filter
The gradual fouling of the filters reduces the flow-rate of the conditioned air, with a consequent reduction in cooling capacity.
In the direct expansion units, a reduction in the air flow-rate may
cause the activation of the low pressure switch and/or cause serious damage to the compressor.
This can be avoided by the periodical cleaning of the filters.
The frequency at which the filters must be checked exclusively
depends on the amount of dust in the environment.
In any case, the following are recommended:
- Every week check that the filters are clean
- Every two weeks clean the filters with a vacuum cleaner
- Every month wash the filters with soapy water
- Every 6 months replace the filters.
It is clear that the recommended times are purely indicative, and
in some cases it may be necessary to increase the frequency of
the checks and maintenance operations.
These operations must be carried out with the unit off and after
having made sure that the appliance is disconnected from the
power supply.
Checking and cleaning the condenser coils
In the hotter period, when the unit operates at maximum capacity, the condensing coils must be able to offer the maximum heat
exchange. Normally installed outside or communicating with the
outside, these may pick up dirt such as paper, dry leaves and dust,
thus reducing the heat exchange.
Make sure that this situation does not arise.
Failure to perform maintenance will cause the activation of the
high pressure switch and the unit to shutdown.
Frequently check the condition of the heat exchanger during the
poplar pollination period or the autumn (falling leaves).
Remove any objects accumulated on the coil and wash with a jet
of water. These operations must be carried out with the unit off
and after having made sure that the appliance is disconnected
from the power supply.
U
I
A
Checking and cleaning the drains
All the water drains (humidifier and condensate) must ensure
perfect drainage, to avoid flooding in the room.
When the humidifiers drain the water, they discharge a quantity
of lime scale that depends on the hardness of the supply water.
This lime scale may accumulate in the bottom of the drain hose
and block the flow of water. If cleaning is required, add ordinary
descaler to the section of circuit involved. This operation must be
carried out with the unit off and after having made sure that the
appliance is disconnected from the power supply.
Checking the drive belt
On the units with fans coupled to the electric motor by pulleys
and drive belts, after a certain number of operating hours the belt
may become loose, sliding on the pulleys and causing excessive
wear. This situation, if it persists, causes overheating and consequently the breakage of the belt. Loosening can be resolved using
the special belt tightener fitted on the appliance (this operation
must be carried out with the unit off and after having made sure
that the appliance is disconnected from the power supply). Check
the tension of the drive belts once a month. Avoid excessively
tightening the belts, as this may cause damage to the bearings.
General examination of operation
This is a general examination aimed at comparing the operation
of the appliance with the last check performed. Consequently, any
differences in the operating characteristics over time can be highlighted. A detailed and periodical visual check of the appliance and
general cleaning are always important to ensure correct operation. The above-mentioned operations can in general be performed once a month. Naturally, in special situations and specific
installations the frequency may change. A well maintained system
is unlikely to cause disruptions and stoppages to the production
cycles. After 10 years working a complete checking is recommended.
Visual check of the condition of the pressurised containers
Check the condition of the pressurised containers at least once a
year (if these are fitted). It is very important to check that rust
does not form on the surface, that there is no corrosion and that
there are no visible deformations. If not controlled and stopped,
surface oxidation and corrosion will over time cause a decrease
in the thickness of the container and a consequent reduction in
its mechanical strength. Protect with paint and/or corrosion
proofing products. In the event of visible deformations, stop the
unit and contact the nearest service centre.
Checking the water-cooled condensers for fouling
To check the water-cooled condensers for fouling, simply check
the water inlet and outlet temperature and compare it against the
condensing temperature.
Normally, for good heat exchange, the difference between the
water outlet temperature and the condensing temperature must
be 5.8°C. Increases in these values, over time, indicate a reduction
in efficiency and consequently the fouling of the condenser.
The condenser is cleaned by chemical washing and must be performed by specialist personnel. This operation must be carried
out with the unit off and after having made sure that the appliance
is disconnected from the power supply).

A) Air or incondensable gas in the refrigerant
circuit, seen by the presence of bubbles, despite
measuring a high subcooling.
B) Insufficient air flow-rate to the remote heat
exchanger or air too hot
Insufficient water flow-rate to the condenser
or water too hot.
Excessive refrigerant charge; condenser
partially flooded. Excessive subcooling of the
liquid at the condenser outlet.
Valves on the high pressure side of the circuit
partially closed.
HIGH PRESSURE
SWITCH ACTIVATED
(high compressor
discharge pressure)
SOLUTION
Empty and recharge the circuit.
Check the operation and the correct direction
of rotation of the fans on the outdoor heat
exchanger.
Check that the exchanger is not dirty and
remove any material that may be blocking it
(leaves, paper, seeds, dust, etc.) with a jet of
compressed air or with a brush;
Check the outdoor unit for any obstacles to
the flow of air and any recirculation of the cooling air;
Check that the temperature of the cooling air
does not exceed the design value.
Check the flow-rate, the pressure and the
temperature of the cooling water in the closed circuit;
Check the calibration and the operation of the
pressure control valve.
Remove refrigerant from the circuit.
Check the opening of the valves.
The condensing pressure control system
isn't working.
Check the operation of the condenser fans
and the corresponding protection device;
repair or replace the faulty fans;
Check the calibration and the operation of the
remote condenser fan pressure switch or the
speed controller.

CAUSE
The condensing pressure control system
isn't working (see the control panel manual).
Excessive water flow-rate to the condenser
or water too cold.
Suction pressure too low
HIGH COMPRESSOR
SUCTION PRESSURE
Thermal load higher than expected
See “LOW COMPRESSOR SUCTION
PRESSURE”.
Check the ambient thermal load; check, above
all for intense dehumidification, the flow-rate
and the conditions of the outside air; check
the inflow of outside air.
Too much refrigerant in the circuit.
Remove refrigerant from the circuit
Check that the thermostatic valve
superheating value is correct; check that the
valve sensor bulb is not discharged and that it
is correctly positioned, secured and
insulated”.a
Room temperature too low
See “ROOM TEMPERATURE TOO LOW”.
The air flow-rate is too low or null
See “LOW OR NO AIR FLOW”.
Liquid receiver outlet valve not
completely open
Check the opening of the valve.
Check that the thermostatic valve
superheating value is correct; check that the
valve sensor bulb is not discharged and that it
is correctly positioned, secured and insulated”.
Insufficient refrigerant charge
Check the liquid subcooling at the condenser
outlet; if necessary, restore the charge.
Thermostatic valve not correctly calibrated
or faulty
Check that the thermostatic valve superheating
value is correct (around 5°C).
Dewatering filter cartridge dirty
The system is affected by an excessively
low discharge pressure
