Maintenance
If you plan to idle the unit for a long time, perform the following:
1. Operate the fan for about 6 hours to dry the inside of the unit.
2. Stop the air conditioner and disconnect power. Remove the batteries from the remote controller.
3. The outdoor unit requires periodic maintenance and cleaning. This should only be done by an authori-
zed airconditioning engineer.
Checks before operation
• Check that the wiring is not broken or disconnected.
• Check that the air filter is installed.
• Check if the air outlet or inlet is not blocked after the air conditioner has not been used for a long time.
