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 part are completely sealed. This unit requires absolutely no
lubrication.
There is a fan behind the compressor, so be very careful if you stick your hand into this part of the unit.
Cleaning of condenser filter
This unit is provided with the filter check lamp on the control panel. Clean the filter when this lamp lights.
Clean the filter once a month even if the check lamp is not on since a clogged filter may cause shorter
compressor life as well as the poor cooling.
Clean the filter by the procedure below.
1. Open the grille by pulling it to you as shown in the
figure.
2. Take out the condenser filter.
3. Wash the filter with water.
4. Replace the filter and the grille.
5. Check that the filter check lamp is off in the event the
check lamp was ON.
WARNING
Do not touch the condenser directly when the filter is removed for cleaning. This may cause injury by
hot surface.
