DAIKIN DECK UNIT "USDP~GR" Series
1. Introduction of DAIKIN DECK UNIT
"DECK UNIT" is one of the Central Air Conditioners for accommodation area,which is assembled in
advance by the manufacturer as a self-contained unit and installed in the machine room on the
accommodation deck.
DAIKIN DECK UNIT- "USDP series is optimally designed for marine application and also gentle for the
environment.
2. Features
¡Very Less Operating Vibration and Lower Noise designed for installing in the accommodation
The adoption of Hermetic Scroll Compressors makes the operating vibration and noise remarkably lower.
This allows the units to install in the accommodation area without troublesome problem.
¡High Static Pressure Fan Easily Conforming to Complex Duct System
The high-performance fan can adapt the complex duct system with middle to higher pressure.
¡The Light Weight and Compact Design of Top Level in the Field
Because of low height ranging from 1,550 to 1,650 A, the unit can be easily installed in even space-limited
deck.
Also the light weight from 1,100 to 1,600 O does not interfere with the cruising speed of high-speed ferry.
¡Epoch-making Save Energy in Spite of HFC Unit
Optimally designed Scroll Compressors and heat exchangers combined with high-performance fan
reduce the power consumption by 15 to 20 %, compared with conventional units. This also contributes to
control the CO2 emission from the generator.
¡Excellent Durability for Marine Application
Higher reliability is secured by the concentration of the DAIKIN advanced technology, for sea water, sea
breeze and ship motion.
¡Economical Maintenance on Board
Installing compressors, which realize 40,000h in design service life, in plural not only realizes the free
maintenance on board, but save the service cost of compressors by half, compared with the conventional
unit.
This also enables the unit to continuously operate even in trouble of one compressor.
Furthermore, the lighter compressor provided with lifting hook allows replacing work to be easier on
board.
3.Guide Specifications
Hermetically Sealed Scroll Compressors
The compressor optimally developed for R404A has a longer durability, higher efficiency and very less
vibration, compared with the conventional Semi-hermetic compressor.
Condenser
The condenser is a shell and cross fin tube type highly efficient and highly resistant to sea water.
It is made of aluminum brass in the cooling tubes, naval clad steel in the tube sheet and cast iron with
sacrificial anodes in the water jackets. The joints for water thermometers are provided in the inlet and
outlet headers (USDP30,40,50GR).
Evaporator
The evaporator is a cross fin coil type highly efficient and highly resistant to sea breeze.
It is made of copper tubes and aluminum fins with highly anti-corrosive and hydrophilic treatment.
Steam heater
The steam heater is a cross fin oil type highly resistant to change of air temperature and sea breeze as
well.
It is made of copper tubes and aluminum fins with highly anti-corrosive treatment.
Fan and its relative parts
Highly performed multi-blade fan (USDP25GR,30GR) or turbo fan (USDP40GR,50GR) is mounted based on
those application, driven by V belts with a separate fan motor. The fan bearings are forced oil feed
system,highly durable for sea breeze.
The fan motor is "B" class insulation, totally enclosed fan cooled type, prescribed in JIS C4210.
Control
The unit is operated by the push button switch, and the operating condition can be confirmed by each
pilot lamp.
The meaning of each pilot lamp is -"White": "Normal power into the unit"and "Green" : "Normal
operation".
If "Red" lights up, any safety device works to stop the unit till removing the applied cause.
Multiple compressors are sequentially started in direct-on-line in order to minimize the starting current.
The capacity is controlled in two steps mainly by local thermostat (or possibly by internal thermostat as
well) according to the basis air temperature.
The following electric and safety devices are equipped in the starter or inside the unit to make the
maintenance saving on board.
Non-fuse breakers and ammeters are equipped in the starter for each circuit of comp. or fan motor.
Over current relay(each comp., fan motor), fuses, thermal protectors, high and low pressure switches and
reverse phase protector and so on are equipped in order to prevent the abnormal operation.
The contact terminals indicating "Normal" or "Abnormal" are provided for connecting to the central
observation board.
The power and control cables to/from the central board can be conducted through combing holes on the
bottom side of the starter.
Structure
The outside and inside plates are constructed with the rigid frame in long durability.
Anti-corrosive acrylic powder painting is coated even in every nook and corner-casing, drain pan, bottom
frame, partition plate, fan housing and fan motor base, etc.
Either right or left drain connection allows the condensing drain water to smoothly discharge outside in
rolling angle.
Applicable Standard
The unit is certified by NK standard. This system is so independent only for the air conditioning in the
accommodation that any other rules of classification society are excluded except the ship owner's special
request.

8. Installation Instruction
Warning
¡ Request the installation to the dealer you purchased.
Otherwise it will cause water leak, electric shock and
fire, if you yourself will carry out the installation and
there will be improper works.
¡ Contact the dealer you purchased for the refrigerant
leaks countermeasure.
When unit is installed in a small room, certain
countermeasures are required so that the density of
the refrigerant should not exceed the
permissible density, even if the
refrigerant leaks.If refrigerant leaks
and will be beyond the permissible
density, it may cause an accident with a
short of oxygen.
Caution
¡ Do not install units in a place where there may be
possible leak of a combustible gas.
If the gas leaks and remains around
the units, it may happen to be
ignited.
¡ Grounding wire connection
If a grounding work is not properly done, it
may cause electric shock.
¡ Install a short circuit breaker.
Otherwise, it may cause electric
shock.
¡ Install drain pipes so that the drain can
securely flow out.
Otherwise, it may cause water leak.
Make sure the following instructions so as to operate the unit perfectly and comfortably. If something
inconvenient will be found, be sure to use the unit after it will be amended.
¡ Is the sufficient distance provided to the obstacles around
the unit?
¡ Is the power line only for the use of the airconditioner?
If the power supply line is used together with other electric
equipment, it may cause to cut the breaker or fuse.
¡ Is it not afraid to injure wiring or piping?
¡ Is the unnatural force loaded on the wiring connected in the
field(including grounding wires)?
¡ Is the wiring connected in the field clamped(including
ground wires)?
28
¡ Is the unit installed on the place sufficiently endurable
for the weight of airconditioner? Is the unit fixed tightly with
the foundation bolts onto the floor?
If the bolts are loosened or removed, it will cause noise or
vibration, and unnatural force will be loaded on the piping
or wiring.
¡ Is a drain trap provided on the drain piping?
Unless a trap with the head more than negative pressure is
provided, drainage failure may happen and cause a water
leak.
Carrying in
¡ When hanging up the unit, use the
suspension bolts (Fig 1)and pay
attention to carry out it safely.

Installation
1. Fix the bottom frame of the unit onto
the foundation with the foundation
bolts(Fig 2).
2. Make the horizontal foundation so as to
be endurable against the unit weight.
3. Select the location of installation based
on the easiness of the drain streaming
out.
4. Attach the piping onto the safety valve
in order to release the gas into the air.

Drain Piping
Be sure to provide a trap on each drain outlet.
That is why the trap will prevent not only the induction of bad smell but also slow action of drain stream
caused by the negative pressure inside the airconditioner during operation.
An example of drain trap installation is shown below.
"Head corresponding to the negative pressure" in the Figure stands for the head corresponding to the
negative pressure arisen in the airconditioner.
Drain at upper part

Drain trap
More than the head corresponding
to the negative pressure.
Thermostat
The thermostat(23A1) built in the unit USD(P)~GR is provided as a low temperature protector. Accordingly,
the thermostat should not be used for indoor temperature control. Provide a room thermostat or a
thermostat(23A2) in the return duct in the local field so as to control temperature.
[Location]
¡ Provide a temperature sensor in the return duct or around the inlet part of the return duct flowing into the
room.
¡ Select the location where direct sunshine, chilled air, heated air, and other radiation heat don't influence
the sensor.
¡ Refer to the electric wiring diagram concerning the wiring works.
[Note for the thermostat selection]
¡ Select the thermostat with the differential by 2°C or more, and not to act ON/OFF in a short time.
Caution for the condenser maintenance
(1) Regulate the water flow.
If the water flow rate (water velocity) exceeds the specified amount, tubes can be damaged in a short
time. Control the water flow to maintain the following guidelines.
¡ Condensing temperature : 30°C or higher.
¡ Temp. difference of in- and outlet : 3°C or higher.
(2) Replace the zinc plates.
In order to make the condenser last longer, check the zinc plates for corrosion protection every 3 months.
If worn out, make sure to replace it.
When checking, be sure to turn off the power source of pump.
(3) Cleaning the condenser cooling tubes.
Clean the cooling tubes if necessary.

Gist of Piping Connection Flexibility
This manual indicates the gist that the standard piping direction of the deck unit with rightward connection
will be changed to the opposite direction with leftward connection.
Cooling Water Piping
[Work Procedure]
1. Remove the front and rear cover of the condenser from the
right and the left.
2. Exchange the front cover with the rear cover together with
the packing.
3. Tighten up the covers with bolts.
Note:
Just move the covers horizontally to
each other and don't revolute it upside
down.
4. Tighten up the header with bolts and that's all.
Drain Piping
1) Upper drain piping
[Work Procedure]
Exchange the mating flange in the right with the blind flange in
the left.
2) Below drain piping
[Work Procedure]
1. In case of rightward connection, screw up the short drain
pipe straight to the right side face.
(Use white seal tape on the screw part)
2. In case of leftward connection, remove the left blind cap to
screw up the blind cap to the right.
For the next step, screw up the attached short drain pipe to
the left to finish.
(Use white seal tape on the screw part)
Note:
1. The short drain pipe is accessories part and not to be screwed in
the main unit inherently.
2. The blind cap is attached just in the left side and not attached in
the right side.
33
Relief Gas Piping on Safety Valve
[Work procedure]
Exchange the right side mating flange with the left side blind
flange.
Piping for Steam Heater and Steam Spray.
[Work procedure]
1. Remove the glass fibers in the pass of rightward piping.
2. Remove the short drain pipe at each outlet/inlet piping by
means of a piping wrench. (the short pipe is set to be
screwed).
3. Since the part the piping passes through in the left side
panel is structured as knock punch hole, knock it off.
4. Dismantle the exterior panels in the right and left
7. Restore the exterior panel in the right and left.
8. Wind the glass fibers around the short drain pipe which was
removed, up to the position of 80 mm ~ 90 mm from the
flange face and fix it securely with brass wires. (so that the
steam piping will not touch the casing).
9. Screw the short pipe for piping connection into the left.
10. Attach the blind rubber bush onto the opening in the right
exterior panel(for the prevention of air leakage).
Refer to the next page for the blind rubber bush's size.
Besides, purchase the rubber bush independently.
5. Since the blind plug is screwed in at the left side steam
piping connection, remove it.
6. Screw up the blind plug into the right side piping connection
where the short drain pipe was removed.
34
Note:
When screwing up the blind plug and the pipe for the
connection, wind up the white seal tape on the screw part.
