Sanyo MDF-793AT, MDF-593AT guide

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 CO2 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).
