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. This lamp flickers and the buzzer sounds when the
condenser filter is clogged. Clean the filter according to the following procedure. As a clogged filter
may cause poor cooling and compressor trouble, clean it once a month.

the figure.
2. Remove the mounting magnet securing the grille and
pull open the grille.
3. Remove the filter installed inside the grille, wash it with
water and dry it naturally.
