2. FEATURES
xEASY 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.
xSPACE SAVING
- No space is required on either floor or ceiling. This newly developed super slim design for wall mounting
maximizes floor space usage and enhances ceiling appearance where ceilings are low.
xQUIET OPERATION
- Cooling comfort is improved by whisper-quiet operation which is achieved by a tangential fan.
xEXCELLENT AIR DISTRIBUTION
- Air discharge direction can be adjusted in four directions, manually or automatically by using LCD
remote control.
- The new double louver design with automatic air swing function fully optimizes the room comfort by
distributing the air evenly to the room.
- The unique skew fan design with larger diameter creates better air flow to the operating environment.
xFACILITATED MAINTENANCE ENSURED
-The new design of air discharge housing whereby the fan blower can be easily accessed by just loosing
two screws on the unit to provides a flexible, faster and easier way to clean up the fan blower and
ionizer.
- Maintenance is easy for electrical components, piping and wiring as these are all easily accessible by
merely removing front plastic panel.
x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 auto control will gradually increase or decrease the setting temperature to provide a
comfortable surrounding for sleeping.
- Air flow direction can be controlled automatically.
- Room temperature is controlled by electronic thermostat.
- The real time timer allows the air conditioner to be switched On and Off automatically based on user
settings.
- Turbo mode function is available to enables the required set temperature to be achieved in a short time.
- Ionizer or non-thermal plasma is available to create better air quality.
- Personalized Setting allows user to preset and store 2 groups of personal settings (including timer
setting) in the handset.
- Auto random restart is a function whereby when there is power failure occurred during operation, the
unit will automatically restart as the last setting condition once the power is resumed.

xx
xMOISTURE REMOVAL
-Dry mode with super low indoor fan speed can achieve more affective moisture removal.
-If the room temperature is lower than the set temperature (Cooling mode only), the compressor will cut
out and force on after 9 minutes to remove moisture effectively.
4

xHIGH EFFICIENCY HEAT EXCHANGER
- The compact design of the 3-fold structure heat exchanger provides a large surface are for better and
efficient heat exchange.
-The unique Hydrophilic slit fin has greatly improved the air flow and the contact surfaces with the air thus
to boost the cooling capacity.
xROTARY COMPRESSOR
-The ever popular rotary compressor is more energy efficient and has a higher output to weight ratio.
xSELF DIAGNOSIS
-This function is able to detect and to diagnose any faults occurring in the system by blinking of the LED
lights.
-Simplify and ease for troubleshooting.

a) Hot start
At the beginning of heating operation (cold start, after defrosting or thermostat resumes operation) the indoor
fan operation is controlled in accordance with the temperature of the indoor heat exchanger to send warm air
from the start.
b) Hot keep (Apply to AWM301R)
After thermostat cut out, the indoor fan operation is controlled in accordance with the indoor heat exchanger
temperature to utilize the extra heat and preserve indoor comfort.
The indoor fan can be switched to ON, OFF, INTERVAL by setting the slide switch shown in the diagram. This
slide switch is located at the front frame cover.

Hot Keep (Apply to AWM-GR)
After thermostat cut out, the indoor fan operation is controlled in accordance with the indoor heat exchanger
temperature to utilize the extra heat and preserve indoor comfort.
The indoor fan can be switched to ON, OFF by setting the slide switch shown in the diagram. This slide switch is
located at the front frame cover.
Multisplit Model Selection
The indoor unit can be changed to multisplit model by just selecting MS through the slide switch.
c) Hot spurt
During cold start, the set temperature of controller is increased by 2oC to stabilize the room temperature quickly.

14
(B) TURBO MODE (APPLY TO AWM-GR)
TURBO function is available in COOL, HEAT and DRY modes only. When TURBO function is set, working
temperature for cooling cycle is decreased by 2oC, working temperature for heating cycle is increased by 2oC.
The indoor fan will force to HIGH fan. After 20 minutes, this function will clear automatically, no more offset
temperature for set temperature and indoor fan will restore. Cold start will be overridden when TURBO function
is activated. If TURBO and SLEEP are activated at the same time, the SLEEP mode timer will be reset, it will
resume after TURBO function is cleared.
(C) OVERLOAD PREVENTION IN HEATING OPERATION
During heating operation, if the room temperature and outdoor temperature are high, or when the indoor air
filter is choked, the condensing pressure will increase rapidly. To prevent the burn out of compressor, the M.
C. controller will stop the operation of the air conditioner under this condition.

When outdoor and indoor air temperature raise beyond the operation limit, or when the outdoor coil choked
with dirt, the M.C. controller detects abnormal increase in condensing temperature. It will stop the operation
to prevent compressor burn out.

14. TROUBLESHOOTING
17
When a malfunction of the air conditioner unit is detected, immediately switch off the main power supply before
proceeding with the following troubleshooting procedures.
The following are common fault conditions and simple troubleshooting tips. If any other fault conditions which
are not listed occur, contact your nearest local dealer. DO NOT attempt to troubleshoot the unit by yourself.
No Fault conditions Possible causes / corrective actions
1 The air conditioner unit will not resume after
power failure.
xThe auto restart function is not functioning. Please
turn on the unit with the wireless / wired controller.
2 The compressor does not operate 3 minutes
after the air conditioner unit is started.
xProtection against frequent starting.
xWait for 3 or 4 minutes for the compressor to start
operating by it self.
3 The airflow is too slow or room cannot be
cooled sufficiently.
xThe air filter is dirty.
xThe doors and windows are opened.
xThe air suction and discharge of both indoor and
outdoor units are clogged or blocked.
xThe regulated temperature or temperature setting
is not low enough.
4 Discharge airflow has bad odor. xCigarettes, smoke particles, perfume and others,
which might have adhered onto the coil, may
cause odor.
xContact your nearest dealer.
5 Condensation on the front air grille of the indoor
unit.
xThis is caused by air humidity after an extended
period of operation.
xThe set temperature is too low. Increase the
temperature setting and operate the unit at high
fan speed.
6 Water flowing out from the air conditioner. xSwitch off the unit and contact your nearest
dealer. This might be due to tilted installation.
7 Hissing airflow sound from the air conditioner
unit during operation.
xLiquid refrigerant flowing into the evaporator coil.
8 The wireless controller display is dim. xThe batteries are discharged.
xThe batteries are not correctly inserted.
xThe assembly is not good.
9 Compressor operates continuously. xDirty air filter. Clean the air filter.
xTemperature setting too low (cooling). Use higher
temperature setting.
xTemperature setting too high (heating), Use lower
temperature setting.
10 No cool air comes out during cooling cycle, or
no hot air comes out during heating cycle.
xTemperature setting too high (cooling). Use lower
temperature setting.
xTemperature setting too low (heating). Use higher
temperature setting.
11 On heating cycle, warm air does not come out. xUnit is in defrost mode. Heating operation will
resume after defrost cycle ends.
