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. Note:
• 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 automatically.

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 speed.

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.

• 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 CONTROLLER ILLUSTRATION" for details.

CAUTION

Vertical louver

• 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

SLEEP operation 7 hours timer off Set Temperature 1°C 1°C 1 hour 1 hour

Cooling

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

SLEEP operation Set Temperature 1°C 1°C 7 hours timer off 1 hour 1 hour

Heating

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 operation.

DRYING operation

- The fan speed will be automatically controlled under dry operation.

- 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.

A) When heating has just starting.
B) Defrosting.
C) 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 unit.

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.
