• 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.
