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.

Defrosting

This freezer is direct-cooling type and the frost is built on the chamber wall during long term operation.
The excessive frost possibly make some gap between the cabinet and door gasket, which may cause
poor cooling. Remove the frost inside the chamber once a month. Following shows the procedure for
removing the chamber frost.
1. Temporarily move all the contents of chamber to another freezer.
2. Press the defrost key (DEF) for 5 seconds to stop the refrigerating operation. While the refrigerating
operation is stopped, the current chamber temperature and dF is displayed on the control panel
alternatively.
3. Open the door. Leave the freezer as it is.
4. Remove the cap of drain port on the bottom of the chamber and drain the accumulated water.
5. Wipe up the water remaining in the chamber and then replace the cap of drain port.
6. Press the defrost key (DEF) so that the refrigerating operation can be started.
7. Once the chamber temperature has dropped to the desired temperature, place the original contents
back in the freezer chamber.
Note:
After the defrosting, the refrigerating operation is never resumed automatically. Make sure to press the
defrost key (DEF) to start the freezer operation after defrosting.
While the freezer stops refrigerating operation for defrosting, neither high temperature alarm nor low
temperature alarm is effective.
