Cleaning of the air filter
WARNING
Cleaning of the air filter and other parts of the air filter can involve dangerous work in high places,
therefore ensure work is carried out by qualified service personnel.
Do not attempt it yourself.
NOTE
For Air conditioning systems which are operated regularly, cleaning and maintenance of the
indoor/outdoor units are strongly recommended.
As a general rule, if an indoor unit is operated for about 8 hours a day, the indoor/outdoor units will
need to be cleaned at least once every 3 months.
Cleaning and maintenance shall be carried out by a qualified person.
Failure to clean the indoor/outdoor units regularly will result in poor performance, icing, water
leaking or even compressor failure.

CAUTION
• Use a dry cloth to wipe the remote controller.
• A cloth dampened with cold water may be used on the indoor unit if it is very dirty.
• Never use a damp cloth on the remote controller.
• Do not use a chemically-treated duster for cleaning nor leave such materials on the unit for long.
It may damage or fade the surface of the unit.
• Do not use benzene, thinner, polishing powder or similar solvents for cleaning. These may cause
the plastic surface to crack or deform.
