(e.g. at the end of the season)
Check and remove everything that might be blocking inlet
and outlet vents on the indoor units and outdoor units.
Clean the air filters and casings of indoor units.
Refer to "Cleaning the Air Filter" for details on how to
proceed, and make sure to install cleaned air filters back to
the same position.
Turn on the power at least 12 hours before operating the

Cleaning the Air Filter
Before you clean the air conditioner, be sure the power
supply is off.
Check that the wiring is not broken or disconnected.
Use a dry cloth to wipe the indoor unit and the remote
controller.
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
any such material on the unit for long, as it may damage or
cause fading on the surface of the unit.
Do not use benzene, paint thinner, polishing powder, or
similar solvents for cleaning.

7. MAINTENANCE
The air filter can prevent dust or other particles from going
inside. In the case of blockage of the filter, the working
efficiency of the air conditioner may drastically decrease.
Therefore, the filter must be cleaned once every two weeks
during long time 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 (a replaceable air filter is
an optional fitting).
All filter cleaning should be performed by a suitable
handyperson.
