11.9. Filter Cleaning Control
• 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.
11.9.1. Auto 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.

• The filter cleaning indicator light will move to left or right when filter cleaning is in progress.

- 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.

11.9.3. Timer Filter Cleaning
• 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.

ation will resume automatically.
