Cleaning, Maintenance and After-Sales Service Safety Warning [ Warning ] For safety reasons, always turn off the air conditioner and turn off the power before cleaning the air conditioner. Do not disassemble or repair the air conditioner by yourself; otherwise, it may cause fire or other hazards. Only professional service personnel can carry out the maintenance. - Page 69 Cleaning the Air Filter [ Caution ] Air filters can be used to remove dust or other particles from the air, and if clogged, the effectiveness of the air conditioner will be greatly reduced. Therefore, be sure to clean the air filter frequently when using it for an extended period. If the unit is installed in a place with a lot of dust, it is recommended that you clean the filter once a month.
- Page 70 Maintenance During in-depth maintenance, the air conditioner should be cleaned and maintained by professional technicians every 2 to 3 years. Clean the filter regularly. When operating in a dusty environment, the air flow and capacity of the filter will decrease. The filter may even become blocked, and the air conditioner performance and indoor air compromised.
