Special Function
CLEAN AIR function (on some models)
Improving the quality of indoor air is one of the mission of an air conditioner. This air
conditioner is equipped with ionizer or Plasma Dust Collector (Depending on
specific configuration of the model). With the anions generated by Ionizer, the air
circulation of the air conditioner fills the room with refreshing, natural and healthy
air. The Plasma Dust Collector generates an high voltage ionization zone, through
which the air is converted to plasma. Inside the air most of the dust, smoke, and
pollen particles are captured by the electrostatic filter.
SELF CLEAN function
Function used after the Shut Down of cooling operation to clean the Evaporator
and keep it as fresh for the next operation.
The unit will operate as following sequence:
FAN ONLY mode at Low fan speed--Heating operation with LOW fan speed(applicable to
cooling & heating models only) ---FAN ONLY operation--Stop Operation---Turn off.
This function is only available under COOL (AUTO COOL, FORCED COOL)
and DRY mode.
Before select the function, it is recommended to run the air conditioner under
Cooling operation for about half an hour. Once the Self Clean function is activated,
all TIMER settings will be cancelled.
During Self Cleaning operation, when press the SELF CLEAN button on the
remote controller again will stop the operation and turn off the unit automatically.
Follow Me function
The remote control serves as a remote thermostat allowing for the precise
temperature control at its location.
To activate the Follow Me feature, point the remote control towards the unit and
press the Follow Me button. The remote display is actual temperature at its location.
The remote control will send this signal to the air conditioner every 3 minutes
interval until press the Follow Me button again. If the unit does not receive the
Follow Me signal during any 7 minute interval, the Follow Me mode will be cancelled
Anti-mildew function (on some models)
When turns off the unit on COOL, DRY, AUTO (Cool) mode, the air conditioner
will continue operating for about 10 minutes(depending on models) at LOW fan
This will help to dry up the condensed water inside the evaporator, and prevent the
breeding of mildew.
Under Anti-mildew operation, do not restart the air conditioner until the unit is
completely off.
Manual Operation
NOTE: The unit must be turned off before operating
the manual control button. If the unit is operational,
continue pressing the manual control button until the
unit is off.
Grasp both sides of the panel and pull it down, the
panel opened upward to an angle of 15°. Push the
panel upward and then lift it up.
One press of the manual control button will lead to
the forced AUTO operation. If press the button
twice within five seconds, the unit will operate
under forced COOL operation.
Close the panel firmly to its original position.
This button is used for testing purposes only. You
had better not choose it.
To restore the remote controller operation, use the
remote controller directly.
Adjust the air flow direction properly otherwise, it
might cause discomfort or cause uneven room
Adjust the horizontal louver using the remote
Adjust the vertical louver manually or by the
remote controller(depending on the models)
To set the vertical air flow(Up--Down) direction
Perform this function while the unit is in operation. Use
the remote controller to adjust the air flow direction.
The horizontal louver can be moved at a angle of 6° for
each press or set to move up and down automatically.
Please refer to the “REMOTE CONTROLLER
ILLUSTRATION” for details.
To set the horizontal air flow direction (left - right)
Adjust the vertical louver manually using the lever on
the left or right side of the vertical louver arm
(Depending on model). Take care not to catch fingers
on the fan, horizontal louver or to damage vertical
louvers. When the air conditioner is in operation and
the horizontal louver is in a specific position, move the
lever at left (or right, depending on model) end of the
air outlet to the desired position. NOTE: For some
models, it can be controlled automatically by the
remote controller. Please refer to the “REMOTE
The SWING buttons will be disabled when the air conditioner is
not in operation.
Do not operate the air conditioner for long periods with the air
flow direction set downward in cooling or dry mode. Otherwise,
condensation may occur on the surface of the horizontal louvre
causing moisture to drop on to the floor or furnishing.
Do not move the horizontal louvre manually. Always use the
SWING button. If you move this louvre manually, it may
malfunction during operation. If the louvre malfunctions, stop
the air conditioner once and restart it.
When the air conditioner is started immediately after it is
stopped, the horizontal louver might not move for approximately
10 seconds.
Open angle of the horizontal louvre should not be set too small,
as Cooling or Heating performance may be impaired due to too
restricted air flow area.
Do not operate unit with horizontal louvre in closed position.
When the air conditioner is connected to power (initial power),
the horizontal louvre may generate a sound for 10 seconds, this
is a normal operation.
Optimal operation
To achieve optimal performance, please note the following:
Adjust the air flow direction correctly so that it is not directed on people.
Adjust the temperature to achieve the highest comfort level. Do not adjust the unit to
excessive temperature levels.
Close doors and windows on COOL or HEAT modes, otherwise performance may be
reduced. Use Timer ON button on the remote control to select a time you want to start
your air conditioner.
Do not put any object near air inlet or air outlet, as the efficiency of the air conditioner
may be reduced and the air conditioner may stop running.
Clean the air filter periodically, otherwise cooling or heating performance may be
reduced. Do not operate unit with horizontal louvre in closed position.
Suggestion: For the unit adopts an Electric Heater, when the outside ambient temperature is
below 0°C, we strongly recommend you to keep the machine plugged in order to guarantee it
running smoothly.
How The Air Conditioner Works
AUTO operation
When you set the air conditioner in AUTO mode, it will
automatically select cooling, heating (cooling/heating
models only), or fan only operation depending on what
temperature you have selected and the room temperature.
The air conditioner will control room temperature
automatically round the temperature point set by you.
If the AUTO mode is uncomfortable, you can select desired
conditions manually.
SLEEP operation
When you push SLEEP button on remote controller during
cooling, heating(cooling only type without), or AUTO operation ,
the air conditioner will automatically increase (cooling) or
decrease (heating) 1°C per hour for the first 2 hours, then hold
steady for the next 5 hours, after that it will switch off. This
characteristic maintains both energy saving and comfort in night
DRYING operation
The fan speed will be automatically controlled under dry
During the dry operation, if the room temperature is lower
than 10°C, the compressor stops operation and restarts until
the room temperature is above 12°C.
Operation Tips
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
• The compressor can't restart for 3 minutes after it stops. Anti-cold air (Cooling and heating models only)
• The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the
following three situations and the set temperature has not been reached.
When heating has just starting.
Low temperature heating.
• The indoor or outdoor fan stop running when defrosting (Cooling and heating models only). Defrosting
(Cooling and heating models only)
• Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity
is high resulting in lower heating efficiency of the air conditioner.
• During this condition air conditioner will stop heating operation and start defrosting automatically.
• The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of
frost build-up on the outdoor unit.
2. A white mist coming out from the indoor unit
• A white mist may generate due to a large temperature difference between air inlet and air outlet on COOL
mode in an indoor environment that has a high relative humidity.
• A white mist may generate due to moisture generated from defrosting process when the air conditioner
restarts in HEAT mode operation after defrosting.
3. Low noise of the air conditioner
• You may hear a low hissing sound when the compressor is running or has just stopped running. This
sound is the sound of the refrigerant flowing or coming to a stop.
• You can also hear a low "squeak" sound when the compressor is running or has just stopped running.
This is caused by heat expansion and cold contraction of the plastic parts in the unit when the
temperature is changing.
• A noise may be heard due to louver restoring to its original position when power is first turned on.
4. Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not been used for a long time or during first use of the
5. A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells permeated from building material, from furniture, or smoke.
6. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and heating models
only) mode.
When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop
automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the
indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and heating models only) to the
set point.
7. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively
humidity (relative humidity higher than 80%). Adjust the horizontal louver to the maximum air outlet
position and select HIGH fan speed.
8. Heating mode (For cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating
operation. When the outside temperature falls, heat drawn in by the air conditioner and will decrease
accordingly. At the same time, heat loading of the air conditioner increases due to larger difference between
indoor and outdoor temperature. If a comfortable temperature can't be achieved by the air conditioner, we
suggest you use a supplementary heating device.
9. Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor
unit starts flashing. To restart the operation, push the ON/OFF button on the remote controller. For the unit
with Auto-restart feature, when the power restores, the unit restarts automatically with all the previous settings
preserved by the memory function.
10. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Disconnect
the unit with power and then re-connect the unit with power again. Push the ON/OFF button on the remote
controller to restart operation.
