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

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

■ 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 2
o
C 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 5
o
C; 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.
