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°C(113°F)) 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).

(2) Check whether grounding wire is in good condition.
(3) Check whether wire connection is correct.

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.
