6.1 Cleaning of Air Filter

1 Remove the air filter on the air inlet for cleaning. Use a dust catcher or water to clean it. If the filter is
very dirty(e.g. greasy), you can clean it using warm water(below 45℃) that is mixed with mild
detergent. Then let it dry naturally under cool places.
2 If the air conditioner is used in dusty place, clean the air filter often(generally once every 2 weeks).

6.2 Maintenance Before Use-season

1 Check whether air inlets and air outlets of indoor units and outdoor units are blocked.
2 Check whether grounding wire is in good condition.
3 Check whether wire connection is correct.
4 Connect the power and check whether the display screen of wired controller shows any characters.

6.3 Maintenance After Use-season

1 When the weather is sunny, operate the air conditioner for half a day to let its inner part dry.
2 If you won't use the air conditioner for a long time, disconnect power please. When power is
disconnected, characters on the display screen will disappear.
