Cleaning the Air Conditioner Mask

To maintain optimal performance of your outdoor Casper SH-09FS32 air conditioner, regular cleaning is essential. Here are the steps to follow:

- Turn off the power to the air conditioner indoors.
- Remove the outer plastic cover of the indoor unit.
- Remove the internal dust filter panels.
- Use a plastic bag to cover and protect the circuit board area to prevent water splashing.
- Secure a plastic tray beneath the indoor unit to catch dirty water during spraying.
- Directly spray water into the metal fins' gaps of the indoor unit. Only spray into the fins' gaps, avoiding other components to prevent damage.
