soft, dry cloth. Do not use bleach or abrasives.

Cleaning the air fi lter
A clogged air fi lter reduces the cooling effi ciency of this unit.
Please clean the fi lter once every 2 weeks.

a clicking sound.
2. Take hold of the handle of the air fi lter and lift it up
slightly to take it out from the fi lter holder, then pull it
downwards.
3. Remove the AIR FILTER from the indoor unit.
• Clean the AIR FILTER once every 2 weeks
• Clean the AIR FILTER with a vacuum cleaner or water,
then dry it up in cool place.

the indoor unit if it is very dirty. Then wipe with a dry
cloth.
• Do not use a chemically treated cloth or duster to
clean the unit.

and place fi lter into position.
CAUTION
• Do not touch the metal parts of the unit when
removing the fi lter. Injuries can occur when handling
sharp metal edges.

following:
1. Operate the fan for about half a day 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. Do not attempt to do this yourself. Contact your
dealer or service provider.

• Check that the wiring is not broken, loose or
disconnected.
• Check that the air fi lter is installed correctly.
