2. When quiet operation is stopped, operation is shifted to normal operation with previous setting.
3. When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
4. When operation mode is changed, quiet operation is shifted to quiet operation of the new mode.
5. During quiet operation, if timer “on” activates, quiet operation maintains.
6. After off, when on back, quiet operation is not memorised.

1. Fan speed is changed from normal setting to quiet setting of respective fan speed.

This is to reduce sound of Hi, Me, Lo for 3dB.

2. Fan speed for quiet operation is -1 step from setting fan speed.

To provide quiet heating operation compare to normal operation.

a. Quiet operation start condition

• When “quiet” button at remote control is pressed.

Quiet LED illuminates.

b. Quiet operation stop condition

1. When one of the following conditions is satisfied, quiet operation stops:

a. Powerful button is pressed.
b. Stop by OFF/ON switch.

c. Timer “off” activates.

d. Quiet button is pressed again.

2. When quiet operation is stopped, operation is shifted to normal operation with previous setting.
3. When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
4. When operation mode is changed, quiet operation is shifted to quiet operation of the new mode, except fan only mode.
5. During quiet operation, if timer “on” activates, quiet operation maintains. 
6. After off, when on back, quiet operation is not memorised.

a. Fan Speed manual

1. Fan speed is changed from normal setting to quiet setting of respective fan speed.

This is to reduce sound of Hi, Me, Lo for 3dB.

2. Fan speed for quiet operation is -1 step from setting fan speed. 
3. Fan Speed Auto

Indoor FM RPM depends on pipe temp sensor of indoor heat exchanger.

When the powerful mode is selected, the internal setting temperature will shift to achieve the setting temperature quickly.

(c) Heating Operation

ON timer can be set using remote control, the unit with timer set will start operate earlier than the setting time. This is to provide a
comfortable environment when reaching the set ON time.

60 minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate for 30 seconds to determine the
indoor intake air temperature and outdoor air temperature in order to judge the operation starting time.

From the above judgment, the decided operation will start operate earlier than the set time as shown below.

OFF timer can be set using remote control, the unit with timer set will stop operate at set time.

1. When the power supply is cut off during the operation of air conditioner, the compressor will re-operate within three to four

minutes (there are 60 patterns of compressor restart waiting time between 2 minutes 58 seconds and 3 minutes 52 seconds
to be selected randomly) after power supply resumes. 

2. This type of control is not applicable during ON/OFF Timer setting.

• Long beep sound will be heard when:-

- Stopping the air conditioner using ON/OFF switch.

• Short beep sound will be heard for others setting.

• Filter cleaning function helps to:

- Clean the filters automatically on a regular basis.
- Avoid airflow blockage caused by dusty filter.
- Prevent growth of mold inside the unit.
- Improve cooling effect that saves energy consumption.

• The dust trapped on the filters surface is sucked and discharged to outdoor by a ventilation motor.
• By default, filter cleaning will run automatically once the unit is turned off if the air conditioner:

- Operates continuously for at least 2 hours and above, and
- Accumulative operation time is at least 2 hours and above.

• The filter surface is divided into rows. Each cleaning cycle will clean one row at a time. The numbers of rows to be cleaned will be

based on the air conditioner’s accumulative operation time and model purchased. The following table is an example for model
1.5 HP.

• The number of cleaning cycle depends on the fan speed setting as well. The table above is an example when the fan speed set-

ting is HI. The number of cleaning cycle will be lesser if the fan speed setting is lower.

• You can also set the filter cleaning manually. For details, see Timer Filter Cleaning and Manual Filter Cleaning.

• Filter cleaning will run automatically after the air conditioner operation stops when air conditioner is turned off using remote con-

trol or turned off by the air conditioner timer.

• After the filter cleaning is completed, the air conditioner operation will remain off.
• The filter cleaning indicator light will move to left or right when filter cleaning is in progress.
• Filter cleaning in progress will be cancelled if:

- Certain buttons on the remote control are pressed.
- The air conditioner main unit’s movable front panel is lifted up.
- There is a power failure.

• Once the air conditioner operation time exceeds 24 hours, the unit is forced to run filter cleaning.
• After the filter cleaning is completed, the air conditioner operation will resume automatically.

• Filter cleaning timer can be set to run at a specified time daily, given that the air conditioner accumulative operation time is at

least 30 minutes and above.

• Filter cleaning timer overrides air-conditioner’s timer in any given setting.
• Once filter cleaning timer starts, air conditioner operation will stop. After the filter cleaning is completed, the air conditioner oper-

ation will resume automatically.

• Manual filter cleaning can be performed a comprehensive filter cleaning.
• A comprehensive filter cleaning may take less than an hour to complete.
• This operation has the highest priority over other operation modes. After the filter cleaning is completed, the air conditioner oper-

ation will resume automatically.

• To circulate the indoor air.
• The ventilation operation is enable by pressing the VENTILATION Button. (As a default setting, ventilation will be turned on auto-

matically once the air conditioner operation starts).

• Operates simultaneously with Auto/Cooling/Drying operation.
• Press VENTILATION button at remote control repeatedly to select your desired ventilation setting. Auto/Cooling/Drying opera-

tion remains as normal regardless of ventilation setting.

• When OFF/ON button at remote control is pressed, all of the air conditioner operations are turned off.

• Ventilation operates independently.
• Ventilation can be turned on when the air conditioner is in non-operation mode.
• Fan speed in this setting remains as AUTO.
• Press OFF/ON button at remote control to turn off the ventilation operation.
