Features
Component Features
Compressor
High efciency, low noise, and hermetically sealed
SCROLL compressors are used in the UATN-C series
to give a better performance.
All compressors are equipped with an internal
overload protection. Crankcase heaters are installed
as standard in each compressor.
Evaporator Coil
Evaporator coils are manufactured from seamless
inner grooved copper tubes mechanically bonded to
aluminium ns to ensure optimum heat transfer.
All coils are tested against leaks by Nitrogen holding
at 609psig and highly precise Helium leak test at
235psig.
Hydrophilic Gold Fin coating evaporator coil is
offered as standard, which could give good effects to
efcient drainage of condensate water as well as heat
transfer performance, and gives superior corrosion
protection even in the harshest environment especially
in coastal area. (1000 hours Salt Spray tested)
Evaporator Fan
The unit is designed with belt driven evaporator motor,
allows for change of pulley on site to accommodate
different static pressure and air ow requirement.
This exibility allows for wider application and offers
the possibility to reach the best working conditions
considering the unit’s characteristics. The fan motor is
IP55 rated protection index with class B insulation
class.
Condenser Coil
Condenser coils are manufactured from seamless
inner grooved copper tubes mechanically bonded to
aluminium ns to ensure optimum heat transfer. All
coils are tested against leaks by Nitrogen holding
at 609psig and highly precise Helium leak test at
235psig.
ALL standard coils are up to 3 rows / 14-16 FPI, 3/8”
(9.52mm) O.D. tubes.
Hydrophilic Gold Fin coating condenser coil is
offered as standard, which gives superior corrosion
protection even in the harshest environment especially
in coastal area. (960 hours Salt Spray tested)
Condenser Fan/Motor
Fans are of propeller type, direct driven by
weatherproof electrical induction motors. Condenser
fan motors are rated IP55 protection index with
class F insulation class and is designed with dust
proof bearing to ensure the reliability of the motor
and smooth operation all year round.
Casing/Structure
The unit casing used in UATN-C series is made of zinc
coated galvanized steel sheets. It is further coated
with an electrostatic powder coat, oven-baked for a
tough and lasting weather resistant nish. Zinc plated
screws are used to further reduce the possibility of
unit rusting.
Coil Guard
The condenser coil is protected by coil guard to
prevent accidental damage during transportation,
handling and installation.

Features
Refrigerant Circuit
The UATN-C series is designed with the ability to
operate at partial load depending on the requirement
of the application.
* Applicable for UATN120C and above.
Each refrigerant circuit has an independent Thermal
Expansion Valve (TXV), Filter Drier and High / Low
Pressure Switch.
Additional valves are provided for site installation of
Pressure Gauge and Low Ambient Kit.
HP
LP
Filter
Saranet pre-lter is available as standard in the unit
to prevent foreign particles entry into the unit.
A 2” lter rail is installed in the unit to accommodate
additional site installed lter.
Phase Sequential Protection
The Phase Sequential Protector is a three phase line
monitor module that protects the unit components
against phase loss, phase reversal and phase
unbalance. It is designed to protect compressors
from reverse rotation. The onboard LED indicators
indicates the ON and FAULT status.

Safety Precautions
This manual provides the procedures of installation to ensure a safe and good standard of operation for the
air conditioner unit.
Special adjustment may be necessary to suit local requirements.
Before using your air conditioner, please read this instruction manual carefully and keep it for future reference.
This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for
commercial use by lay persons.
This appliance is not intended for use by persons, including children, with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
SAFETY PRECAUTIONS
WARNING
● Installation and maintenance should be performed by
qualied persons who are familiar with local code and
regulation, and experienced with this type of appliance.
● All eld wiring must be installed in accordance with the
national wiring regulation.
● Ensure that the rated voltage of the unit corresponds
to that of the name plate before commencing wiring
work according to the wiring diagram.
● The unit must be GROUNDED to prevent possible
hazard due to insulation failure.
● All electrical wiring must not touch the refrigerant
piping, or any moving parts of the fan motors.
● Conrm that the unit has been switched OFF before
installing or servicing the unit.
● Disconnect from the main power supply before
servicing the air conditioner unit.
● DO NOT pull out the power cord when the power is
ON. This may cause serious electrical shocks which
may result in re hazards.
● Keep the indoor and outdoor units, power cable and
transmission wiring, at least 1m from TVs and radios,
to prevent distorted pictures and static. {Depending on
the type and source of the electrical waves, static may
be heard even when more than 1m away}.

The refrigerant quantity is indicated on the unit name
plate. Periodical inspections for refrigerant leaks may
be required depending on European or local legislation.
Please contact your local dealer for more information.
NOTICE
Disposal Requirement
Dismantling of the unit, treatment of the refrigerant, oil and other parts must be done in accordance with the applicable
legislation.
CAUTION
Please take note of the following important points
when installing.
● Do not install the unit where leakage of ammable
gas may occur.
If gas leaks and accumulates around the unit,
it may cause re ignition.
● Ensure that drainage piping is connected properly.
If the drainage piping is not connected
properly, it may cause water leakage which
will dampen the furniture.
● Do not overcharge the unit.
This unit is factory pre-charged.
Overcharge will cause over-current or damage
to the compressor.
● Ensure that the unit’s panel is closed after service
or installation.
Unsecured panels will cause the unit to
operate noisily.
● Sharp edges and coil surfaces are potential
locations which may cause injury hazards. Avoid
from being in contact with these places.
● Before turning off the power supply, set the remote
controller’s ON/OFF switch to the “OFF” position
to prevent the nuisance tripping of the unit. If this is
not done, the unit’s fans will start turning automatically
when power resumes, posing a hazard to service
personnel or the user.
● Do not operate any heating apparatus too close to the
air conditioner unit.
● Don’t use joined and twisted wires for incoming
power supply.
● The equipment is not intended for use in a potentially
explosive atmosphere.
● Used only NITROGEN for air tight test.
● Strictly do not charge OXYGEN or ACETYLENE into the
unit for any purpose.
