Cleaning the air filter
The air filter can prevent dust or other particulate from
going inside. In case of blockage of the filter, the working
efficiency of the air conditioner may greatly decrease.
Therefore, the filter must be cleaned once every two
weeks during extended usage.
If the air conditioner is installed in a dusty place, clean the
the air filter frequently.
If the accumulated dust is too heavy to be cleaned, please
replace the filter with a new one (replaceable air filter is an
optional fitting).
The filter cleaning should be performed by a suitable
service provider.
A wet cloth may be used to clean 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 wiping or
leave such material on the unit for long.
It may damage or fade the surface of the unit.
Do not use benzine, thinner, polishing powder, or similar
solvents for cleaning.
These may cause the plastic surface to crack or deform.
Do not dry out the air filter under direct sunshine or with fire.
