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.

•Check the back-up system by pressing CO2 back-up test switch (TEST) once a month if it is installed.

•Remove the frost or ice on the chamber wall and clean the condenser filter once a month.

Cleaning of condenser filter

This unit is provided with the filter check lamp. This lamp blinks 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.

1.The filter fitted to the grille can be removed as shown in the figure.

2.Wash it with water and dry it naturally.

3.Replace the clean filter as before.

4.Replace the grille in the basic position and check that the filter check lamp is off.

Defrosting of inside wall

Defrost the inside wall of the freezer as follows:

Normal defrosting

Remove the frost by the enclosed scraper. Take care not to damage the inside wall.

Thorough defrosting

1.Take out and transfer all the contents to another freezer or container which contains liquid CO2, liquid N2, or dry ice. Switch off the alarm and back-up system. Switch off the power switch.

2.Open the door and remove the inner lid. Leave the freezer as it is. The water remaining in the freezer compartment should be wiped up.

3.After cleaning is completed, restart the operation according to the procedure on page 13. Put back the articles into the sufficiently cooled freezer compartment.
