The air filter is always an easily overlooked component in the system. In order to ensure the
effective operation of the equipment, the filter should be tested once a month and cleaned and
replaced immediately when needed.
Before replacing the unit air filter, please ensure that the unit fan is stopped, otherwise it may
cause injury accidents.
The air filter of the indoor unit is installed at the return air vent. Open the rear door panel,
loosen the platen assembly and rotate it 90 degrees, and then the filter can be taken out directly.
