CAUTIONS FOR USAGE
This unit is provided with the filter check lamp. If the filter check lamp is flashed, clean the condenser
filter. Refer to page 23 “Cleaning of condenser filter”. A clogged filter may cause poor cooling and
compressor trouble.
When connecting a liquid CO

cylinder for the back-up system of AT type freezer, consult your dealer
of a neighboring engineering shop of high pressure gas.
Leave the remote alarm switch “OFF” until the inside temperature of the freezer reaches the
appropriate level. Leave the back-up system switch “OFF” as well for AT type. After the inside
temperature reaches the appropriate level, set the needle for the warning device operation of the
temperature recorder.
When the unit is first installed, or re-started after long period of no use, the power failure alarm may not
operate, because its Cadnica batteries have completely discharged. This does not denote a malfunction.
In this case, continue to operate the unit for about 3 hours. To fully recharge the completely discharged
batteries, the unit has to be operated for about 2 days.
Cover the control panel with the control panel cover to avoid the malfunction resulting from an
accidental contact with control panel (such as power switch OFF).
