For AT type, turn OFF the back-up switch at the time of opening of the freezer door when a liquid CO2 gas cylinder is connected to the back-up system.

Put on dry gloves when you take out refrigerated articles from the freezer. Handing frozen contents or the inside walls with naked hands may cause frostbite.

For the cleaning of the unit, 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 to clean the unit, wipe the unit thoroughly with a cloth soaked in clean water. Then wipe the unit with a dry cloth to eliminate the moisture.

Do not clean the unit with scrubbing brushes, acid, thinner, solvents powdered soap, cleanser or hot water. These agents can scratch the paint or cause it to peel. Plastic and rubber parts can be easily damaged by these materials. Especially never use any volatile solvent to clean the plastic or rubber parts.

The cooling pipe is routed in the rear of the freezer. Never use a knife or a screw driver, etc. to remove the frost. They may cause damage of chamber wall or improper operation of the unit. And do not make any holes for attaching accessories on the freezer wall.

The digital thermometer of this unit is designed to display the temperature of the center part of the freezing compartment. Although the thermometer sometimes display a temperature about 2oC higher than the actual temperature of the center part, it gradually approaches the real temperature.

Do not put too many warm articles into a freezer compartment before enough operating. Put items in a few at a time after the freezer compartment temperature has cooled enough.

The space near the freezer compartment door, about 10 cm from the inner lid, sometimes shows a higher temperature than the center part. The difference is about 5oC; the lower part may be better for long term storage.

Before operating the freezer, an inner lid should be put in to reduce temperature difference between top and bottom of the freezing compartment.

When it is desired to place an instrument requiring measuring cable and power cord in the cabinet, the cable and cord can be led through the access port provided on the left side wall on the cabinet. After installation, replace a rubber cap and insulation as they are. Failure to use a rubber cap or insulation can interfere with the proper lowering of temperature and lead to condensation on the outside of the port.
