ROUTINE MAINTENANCE
WARNING
Always disconnect the power supply to the unit prior to any repair or maintenance
of the unit in
order to prevent electric shock or injury.
Ensure you do not inhale or consume medication or aerosols
from around the unit at the time of
maintenance. These may be harmful to your health.
Cleaning of cabinet
• Clean the unit once a month. Regular cleaning keeps the unit looking new.
• Use a dry cloth to wipe off small amounts of dirt on the outside and inside of the unit and all accessories.
If the outside panels are dirty, clean them with a diluted neutral dishwashing detergent (Undiluted
detergent can damage the plastic components. For the dilution, refer to the instruction of the detergent).
After the cleaning with the diluted detergent, always wipe it off with a wet cloth. Then wipe off the cabinet
or accessories with a dry cloth.
• Never pour water onto or into the unit. Doing so can damage the electric insulation and cause failure.
• The compressor and other mechanical parts are completely sealed. This unit requires absolutely no
lubrication.
Note:
Always replace the inner accessories removed for the cleaning to keep the intended performance.
Cleaning of condenser filter
This unit is provided with the filter alarm indicator on the LCD touch panel. Clean the condenser filter

1.
Open the grille by pulling it to you as shown in the
figure.
2.
Take out the condenser filter.
3.
Wash the condenser filter with water.
4.
Replace the condenser filter and the grille. (Set the
handle of the condenser filter at the front.)
5.
Check that the filter alarm indicator is off in the event
the filter alarm indicator was ON.
WARNING
Do not touch the condenser directly
when the filter is removed for cleaning.
This may cause injury by
hot surface.
