2. FEATURES
• 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
maximizes floor space usage and enhances 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.
- 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.
• FACILITATED 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.
• 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.
••
••
• MOISTURE 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.

• HIGH 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.
• ROTARY COMPRESSOR
- The ever popular rotary compressor is more energy efficient and has a higher output to weight ratio.
• SELF 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) 3 HOT SYSTEM (HEATING CYCLE)
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 MWM030FR)
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.
Downloaded from AC-Manual.com Manuals
23
(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.

CAUTION: Before installing the unit, ensure that the power supply matches the power requirement of the air
conditioner.
1) SELECTION OF LOCATION AND SPACE
(A) INDOOR UNIT
Install the fan coil (indoor) unit at a location with the following requirements
• Location is suitable for wiring, piping and drainage.
• No obstruction of air flow into and out of unit where cooler air can be evenly distributed.(See fig. 1)
• Ensure that air discharge is not short circuited with air intake.
• Ensure that wall is sufficiently strong, rigid, flat, perpendicular and vibration free.
• Where air filter cassette can be slided in or out easily.
• Where there is no danger of flammable gases.
• Where there is no direct sunlight on unit.
• Also to take into consideration a place for the installation of the Wireless LCD Remote Controller.
CAUTION : Do not install unit near the door way
because excessive fresh air may cause
panel condensation on the unit.
Fig. 1
Downloaded from AC-Manual.com Manuals
27
(B) OUTDOOR UNIT
As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum
cooling capacity, the location selected for outdoor unit should fulfill the following requirements :
• Install the condensing (outdoor) unit in a way such that hot air distributed by the outdoor condensing unit cannot be
drawn in again (as in the case of short circuit of hot discharge air). Allow sufficient space for maintenance around the
unit
.
• Ensure that there is no obstruction of air flow into or out of the unit. Remove obstacles which block air intake or
discharge.
• The location must be well ventilated, so that the unit can draw in and distribute plenty of air thus lowering the condensing
temperature.
• A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.
• A place protected from direct sunlight. Otherwise use an awning for protection, if necessary.
• The location must not be susceptible to dust or oil mist.
INSTALLATION CLEARANCE
• Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air
flow. Select the coolest possible place where intake air should not be hotter than the outside temperature (max. 45°C)
ALL MODELS A B C D
Minimum Distance 300 mm 1000 mm 300 mm 500 mm
CAUTION : If the condensing unit is operated in an atmosphere containing oils(including machine oils),
salt(coastal area), sulphide gas(near hot spring, oil refinery plant), such substances may lead to failure of the
unit.

CONDENSED WATER DISPOSAL OF OUTDOOR UNIT (HEATPUMP UNIT ONLY)
• There are 2 holes on the base of outdoor unit for condensed water to flow out. Insert the drain elbow to
one of the holes.
• To install the drain elbow, first insert one portion of the hook to the base (portion A), then pull the drain
elbow in the direction shown by the arrow while inserting the other portion to the base. After installation,
check to ensure that the drain elbow clings to base firmly.
• If the unit is installed in a snowy and chilly area, condensed water may freeze in the base. In such case,
please remove plug at the bottom of unit to smooth the drainage.
