GENERAL UPKEEP

CARE and CLEANING –

To insure good sanitation, appear-

ance, and minimum maintenance, the cabinet
should be cleaned and washed regularly as
use demands. Clean with mild detergent and
warm water. DO NOT USE AN ABRASIVE
CLEANER OR STEEL WOOL AS THEY
WILL MAR THE FINISH.

ROUTINE MAINTENANCE –

Under normal conditions, after the

cabinet is installed and running, very little
maintenance should be required. However,
the following list of housekeeping practices
will assure trouble-free operation.

1. Check operation of condenser fan motors.

Fan blades must turn freely.

2. Check drain pan and heater to prevent

accidental overflow.

3. Make sure doors are closing properly and

that the gaskets seal.

4. Make sure all evaporator fan motors are

running. These can be seen through grill
inside cabinet.
