Routine Maintenance - Gree GKH24S3GI Owner's Manual

7.2 Routine Maintenance

Only a qualified service person is allowed to perform maintenance.
Before accessing to terminal devices, all power supply circuits must be
disconnected.
Do not use water or air of 50° C or higher for cleaning air filters and outside panels.
Notes:
①. Do not operate the air conditioner with the filter uninstalled, otherwise dust would come into the unit.
②. Do not remove the air filter except for cleaning. Unnecessary handling may damage the filter.
③. Do not clean the unit with gasolene, benzene, thinner, polishing powder or liquid insecticide,
otherwise it would cause discoloration and deformation of the unit.
④. Do not wet the indoor unit in case of electric shock or fire hazard.
Increase the frequency of cleaning if the unit is installed in a room where the air is
extremely contaminated. (As a yardstick for yourself, consider cleaning the filter once a
half year.)
If dirt becomes impossible to clean, change the air filter.
