INSTALLATION MANUAL
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 requirement.
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 qualified
persons who are familiar with local code and regulation, and
experienced with this type of appliance.
• All field 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.
• Confirm 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 fire
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}.
CAUTION
Please take note of the following important points when
installing.
• Ensure that the drainage piping is connected properly.
If the drainage piping is not connected properly, it may
cause water leakage which will dampen the furniture.
• 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 install the units at or near doorway.
• Do not install the units at area like hot spring or oil refinery
plant where sulphide gas exists.
• Do not operate any heating apparatus too close to the air
conditioner unit or use in room where mineral oil, oil vapour or
oil steam exist, this may cause plastic part to melt or deform as a
result of excessive heat or chemical reaction.
• When the unit is used in kitchen, keep flour away from
going into suction of the unit.
• This unit is not suitable for factory used where cutting oil
mist or iron powder exist or voltage fluctuates greatly.
• Ensure the color of wires of the outdoor unit and the
terminal markings are same to the indoors respectively.
• IMPORTANT : DO NOT INSTALL OR USE THE AIR
CONDITIONER UNIT IN A LAUNDRY ROOM.
• Don’t use joined and twisted wires for incoming power
supply.
• The equipment is not intended for use in a potentially
explosive atmosphere.
NOTICE
Disposal requirement
Your air conditioning product is marked with this symbol. This means that electrical and electronic products shall not be mixed
with unsorted household waste.
Do not try to dismantle the system yourself: the dismantling of the air conditioning system, treatment of the refrigerant, of oil and of
other parts must be done by a qualifi ed installer in accordance with relevant local and national legislation.
Air conditioners must be treated at a specialized treatment facility for re-use, recycling and recovery. By ensuring this product
is disposed of correctly, you will help to prevent potential negative consequences for the environment and human health. Please
contact the installer or local authority for more information.
Batteries must be removed from the remote controller and disposed of separately in accordance with relevant local and national
legislation.

INSTALLATION OF THE INDOOR UNIT
The indoor unit must be installed such that there is
no short circuit of the cool discharge. Respect the
installation clearance.
Do not put the indoor unit where there is direct
sunlight on unit. The location is suitable for piping
and drainage and it must have a large distance
between a door and unit.
In cases where the temperature above the ceiling
might reach 30°C or the humidity RH80%, reinforce
the drain pan insulation (10mm or thicker) or adding
secondary Drain Pan. Condensation may form on
the surface of the insulating material.
Provide clearance for servicing ease and optimal air
flow as shown in the diagram.
Ceiling Concealed Mounting
• Use the hanger supplied with the unit.
• Make sure that the ceiling is sufficiently strong to
withstand the weight.

DRAIN PIPE
The suggested slope of the
drain pipe is at least 1:50
Insulate securely
10mm (0.39")
• The drain pipe must be installed as shown in the diagram (see diagram above) to avoid damage caused by
leaks and condensation.
• For the best result, keep the piping as short as possible. Slant the piping at an angle to improve the flow.
• Ensure the drain pipe is securely insulated.
• Keep pipes as straight as possible for easy cleaning and to prevent the accumulation of dirt and debris.
• Conduct a water drainage test after the installation is completed. Make sure that the drainage flow is smooth.
• In humid environments, use an extra drain pan to cover the entire area of the indoor unit.

WATER PIPING CONNECTION
• The indoor unit is equipped with water outlet and inlet connection. There is an air-vent that is fitted along
with the connection for air purging.
• 3 way valve is required for cycling off or bypass the chilled water.
• Black steel pipe, closed cell polyurethane pipe and copper tube are recommended in the field installation.
All types of piping and connection must be insulated with closed cell polyurethane to avoid condensation.
• Do not use contaminated or damaged pipe and fitting for installation.
• Some main fitting components are needed in the system to enhance the capacity and ease of service, such as
gate valve, balancing valve, 2 way or 3 way valve, strainer and etc.

SERVICE AND MAINTENANCE
Service Parts Maintenance Procedures Period
Indoor Air Filter 1. Remove any dust adhering to the filter by using a
vacuum cleaner or wash in lukewarm water (below
40°C) with a neutral cleaning detergent.
2. Rinse the filter well and dry before placing it back onto
the unit.
3. Do not use gasoline, volatile substances or chemicals to
clean the filter.
At least once
every 2 weeks.
More frequently if
necessary.
Indoor Unit 1. Clean any dirt or dust on the grille or panel by wiping
it with a soft cloth soaked in lukewarm water (below
40°C) and a neutral detergent solution.
2. Do not use gasoline, volatile substances or chemicals to
clean the indoor unit.
At least once
every 2 weeks.
More frequently if
necessary.
CAUTION
Avoid direct contact of any coil treatment cleaners on plastic part. This may cause plastic part to
deform as a result of chemical reaction.
TROUBLESHOOTING
For any enquiries on spare parts, please contact your authorized dealer. If any malfunction of the air
conditioner unit is noted, immediately switch off the power supply to the unit. Check the following fault
conditions and causes for some simple troubleshooting tips.
Fault Causes / Action
1. The air conditioner unit does not operate. – Power failure, or the fuse need to be replaced.
– The power plug is disconnected.
– It is possible that your delay timer has been set
incorrectly.
2. The air flow is too low. – The air filter is dirty.
– The doors or windows are open.
– The air suction and discharge are clogged.
– The regulated temperature is not high enough.
3. Discharge air flow has bad odor. – Odors may be caused by cigarettes, smoke
particles, perfume etc. which might have adhered
onto the coil.
4. Condensation on the front air grille of the indoor
unit.
– This is caused by air humidity after an extended
long period of operation.
– The set temperature is too low, increase the
temperature setting and operate the unit at high
fan speed.
5. Water flowing out from the air conditioner unit. – Switch off unit and call local dealer / serviceman.
If the fault persists, please call your local dealer / serviceman.
