About

Filter cleaning

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 heating/cooling effect that 

saves energy consumption.

Auto Filter Cleaning

•  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.

< 2 hours

2 hours and < 6 hours

6 hours and < 9 hours

3

5

6

18 hours and < 21 hours

•  The number of cleaning cycle depends on the fan speed setting as well. The table above is 

an example when the fan speed setting 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 in the following pages.

Troubleshooting

● When the fi rst air conditioner operation is initialized, 

fi lter cleaning will run one cycle automatically.

►  This is a normal operation to make sure the fi lter cleaning device is able 

to move smoothly.

►  Filter cleaning will not be terminated by pressing any of the remote 

control buttons. Filter cleaning will stop by itself after operates for one 
cycle.
