•EASY INSTALLATION
-The wall mounted fan coil unit is easily installed because of its compact size, slimness and light
weight.
-Slim and short outdoor unit can be easily installed even in a narrow balcony and passageway and
yet have a stable profile.
•SPACE SAVING
-No space is required on either floor or ceiling. This newly developed super slim design for wall
mounting maximises floor space usage and enhance ceiling appearance where ceilings are low.
•QUIET OPERATION
-Cooling comfort is improved by whisper-quiet operation which is achieved by a tangential fan.
•EXCELLENT AIR DISTRIBUTION
-Air discharge direction can be adjusted in four directions, manually or automatically by using LCD
remote control, coupled with good air flow, the unit provides excellent air distribution.
•FACILITATED MAINTENANCE ENSURED
-The new design cassette filter is slide-out type which can be easily removed at the air inlet grille for
cleaning.
-Maintenance is easy for electrical components, piping and wiring as these are all easily accessible
by merely removing front plastic panel.
•WIRELESS REMOTE CONTROL
-The compact LCD transmitter is able to operate the air conditioner unit within the distance of 9
meters.
-Fan motor speed can be set at low/medium/high or automatic.
-Sleep mode automatically increase set temperature since room temperature is lower at night thus
achieving comfort surrounding.
-Air flow direction can be controlled automatically.
-Room temperature is controlled by electronic thermostat.
-The unit can be preset to on and off automatically for maximum of 15 hours by using timer on/off.
•SLIT FIN
-The unique Hydrophilic slit fin has greatly improved the air flow and the contact surfaces with the air
thus to boost the cooling capacity.
•ROTARY COMPRESSOR
- The ever popular rotary compressor is more energy efficient and has a higher output to weight ratio.

Before operating, please read the following "Safety Precautions"
carefully.
To prevent injury to the user or other people and properties damage, the following instructions must be
followed.
§Incorrect operation due to ignoring of instruction will cause harm or damage, the seriousness is
classified by the following indications.
Warning: This sign indicates the possibility of causing death or serious injury.
Warning
·This unit must be installed by a qualified technician.
·All field wiring must accordance to the National Wiring Regulation.
Important
The wires in this mains lead are coloured in accordance with the following code:
Green-and-yellow Earth
Blue Neutral
Brown Live
As the colours of the wires in the mains lead of this appliance may not correspond with the
coloured markings identifying the terminals in your plug, proceed as follows:
•The wire which is coloured green-and
the plug which is marked with the earth symbol or
-yellow must be connected to the terminal in
coloured green or
green-and-yellow.
•The wire which is coloured blue must be connected to the terminal which is
marked with the letter N or coloured black.
•The wire which is coloured brown must be connected to the terminal which is
marked with letter L or coloured red.
Note
If the supply cord is damaged, it must be replaced by the special cord obtainable at
authorized service/parts centers.
This unit is not provided with a plug, therefore the power supply wire must be connected by
a qualified chargeman.
Caution
Remove power plug or disconnect from the mains before servicing the appliance.
5. SAFETY PRECAUTIONS BEFORE INSTALLATION
Caution:
This sign indicates the possibility of causing injury or damage to properties
only.

Symbol (with white background) denotes item that is PROHIBITED from doing.
Symbol (with black background) denotes item that is COMPULSORY to be carried out.
Please confirm the following important points when installation
• Grounding is necessary
It may cause electrical shock if grounding is not perfect.
• Do not install the unit where leakage of flammable gas may occur
In case of gas leaks and accumulates at the surrounding of the unit, it may cause
fire ignition.
§Confirm drainage piping is connected properly
If it is not connected perfectly, it may cause water leakage and dampen the
furniture.
• Confirm the unit is switched off before install, service or maintain the unit
If it is not switched off, it may cause injury to the installer by any of the moving part
especially fan.
• Do not overcharge the unit
This unit is factory pre-charged. Over charge will cause over current or damage to
the compressor.
Refer to page 25 in case of top up charge is necessary.
• Confirm cover back the unit panel after servicing or installation
Unsecure panel will cause unit noisy.

SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R407C UNIT
1) What is new refrigerant R407C?
R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and
thus conformed to the Montreal Protocol regulation. It requires Polyol-ester oil (POE) oil for its
compressor's lubricant. Its refrigerant capacity and performance are about the same as the
refrigerant R22.
2) Components
Mixture weight composition R32(23%), R125(25%), R134a(52%)
3) Characteristic
•R407C liquid and vapor components have different compositions when the fluid evaporates or
condenses. Hence, when leak occurs and only vapor leaks out, the composition of the refrigerant
mixture left in the system will change and subsequently affect the system performance. DO NOT
add new refrigerant to leaked system. It is recommended that the system should be evacuated
thoroughly before recharging with R407C.
•When refrigerant R407C is used, the composition will differ depending on whether it is in gaseous or
liquid phase. Hence when charging R407C, ensure that only liquid is being withdrawn from the
cylinder or can. This is to make certain that only original composition of R407C is being charged into
the system.
•POE oil is used as lubricant for R407C compressor, which is different from the mineral oil used for
R22 compressor. Extra precaution must be taken not to expose the R407C system too long to moist
air.
4) Check list before installation/servicing
•Tubing
Refrigerant R407C is more easily affected by dust of moisture compared with R22, make sure to
temporarily cover the ends of the tubing prior to installation
•Compressor oil
No additional charge of compressor oil is permitted.
•Refrigerant
No other refrigerant other that R407C
•Tools
Tools specifically for R407C only (must not be used for R22 or other refrigerant)
i) Manifold gauge and charging hose
ii) Gas leak detector
iii) Refrigerant cylinder/charging cylinder
iv) Vacuum pump c/w adapter
v) Flare tools
vi) Refrigerant recovery machine
5) Handling and installation guidelines
Like R22 system, the handling and installation of R407C system are closely similar. All precautionary
measures; such as ensuring no moisture, no dirt or chips in the system, clean brazing using nitrogen, and
thorough leak check and vacuuming are equally important requirements. However, due to zeotropic
nature of R407C and its hydroscopic POE oil, additional precautions must be taken to ensure optimum
and trouble-free system operation.
a) Filter-dryer must be installed along the liquid line for all R407C air conditioners. This is to minimise
the contamination of moisture and dirt in the refrigerant system. Filter-dryer must be of molecular
sieve type. For a heat-pump system, install a two-way flow filter dryer along the liquid line.
b) During installation or servicing, avoid prolong exposure of the internal part of the refrigerant system
to moist air. Residual POE oil in the piping and components can absorb moisture from the air.
