CAUTIONS FOR USAGE
￭ The top surface of the frame sometimes becomes hot during the initial operation or when operating in a
hot environment. This is due to the hot gas circuit for preventing dew, and is not an indication of a
malfunction.
￭ This unit is provided with the filter check lamp. If the filter check lamp is flashed, clean the condenser
filter. Refer to page 25 “Cleaning of condenser filter”. A clogged filter may cause poor cooling and
compressor trouble.
￭ When connecting a liquid CO
2
tank for the back-up system of MDF-192AT 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 MDF-192AT. 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).
