WARNING:
Disconnect equipment from main power before attempting
any maintenance to equipment or its control unless stated otherwise.
8.1 Cleaning the Cabinet
The interior and exterior of the cabinet should be cleaned every three
months, more often if necessary.
To clean the interior of the unit, use a dilute bleach (10% bleach and 90%
water) or alcohol solution. The shelves and baskets may be removed for
easier cleaning. Do not expose the surfaces to thinner, acid, or any other
harsh solvent. Rinse the shelves and wipe them dry with a soft cloth.
Wipe down the freezer exterior using soap and water and a general use
laboratory disinfectant. Rinse thoroughly with clean water and dry with a
soft cloth.
8.2 Cleaning the
Condenser
CAUTION:
Condensers should be cleaned at least every two months. In
heavy traffic areas, condensers load with dirt more quickly. Failure to keep
the condenser clean can result in equipment warm-up or erratic
temperatures.
WARNING:
Be sure to disconnect the unit from main power before
cleaning the condenser.
CAUTION:
Never clean near condensers with your fingers. Some surfaces
are sharp.
To clean the condenser:
1. Disconnect the power.
2. Slide the front grill to the right.
3. Remove both filters.
4. Use a vacuum cleaner with hose and soft brush attachments to clean the
front face of the finned surface.
