Cleaning of cabinet
• Clean the unit once a month. Regular cleaning keeps the unit looking new.

If some of them are dirty, use a cloth containing diluted neutral dishwashing detergent (Undiluted
detergent may break the plastic parts. For the dilution, follow the instruction enclosed with the
detergent). When a diluted neutral dishwashing detergent is used, wipe the cabinet or accessories
thoroughly with a cloth soaked in clean water. Then wipe the cabinet or accessories unit with a dry cloth
to eliminate the moisture.

electric shock or short circuit.
• The compressor and other mechanical part are completely sealed. This unit requires absolutely no
lubrication.
