personnel.
Cleaning the Unit
Before beginning cleaning unit follow these instruction listed
below:
•
Disconnect power cord from its outlet.
•
Set the temperature control to the OFF position.
•
The unit designs permit easy and rapid cleaning and
should not take more than a few minutes. Remember to
wear protective gloves to prevent frost bite, especially
when removing items from the unit.
•
Do not use abrasive scouring powders, waxes, solvents,
furniture polish, undiluted detergents or cleansers
containing petroleum products on the surfaces of units.
Cleaning Interior/Exterior/
Door Gaskets
A solution of mild soap/detergent and lukewarm water can be
used for cleaning the interior, exterior and door gaskets with a
soft, clean cloth. Rinse with clean water and dry thoroughly
before reconnecting and turning on the unit.
The cabinet interior should be cleaned frequently. Any spilled
liquid should be wiped off immediately since stains resulting
from some spills could be permanent if not quickly removed.
The most convenient time to clean the interior is after
defrosting.

Maintenance
Cleaning the Condenser
With forced-fan vented units, remove the screws that mount
the grill to the unit. Pull temperature control knobs straight out
this will expose condenser for cleaning.
These surfaces may be warm to the touch. The condenser
should be cleaned before becoming clogged with dirt/dust.
Construction or other dirt causing environments may
significantly increase the required frequency. The condenser
should be cleaned at least once a year.
CAUTION: Never clean around the condensers
with your fingers. Some surfaces are sharp.
Manual Defrost Procedure
Use the following procedure to defrost manually:
•
Rotate the temperature control knob to the OFF setting
or zero position according to the model.
•
Disconnect the power cord from its outlet.
•
Remove contents of the unit. If practical, wrap contents
in paper and then in a heavy blanket to maintain
temperature of items. Wear protective gloves to prevent
from frost bite when handling cold items.
•
Open door and allow free circulation of ambient air.
•
To speed the process, place pan of warm water inside
the chamber.
•
Wipe out the interior.
•
Replace the contents.
•
Reconnect the power cord to outlet and set temperature
control to desired operating temperature
CAUTION: Do not use any sharp instruments,
blade or scraper to remove ice and frost on
refrigerator surfaces because of the very real
danger of puncturing the cooling coil.
CAUTION: Do not use any electrical devices to
defrost the unit.
