Troubleshooting
When using this appliance, you may come across some problems that in many
cases result from improper handling and can easily be eliminated.
TROUBLESHOOTING GUIDE
The appliance fails to operate after being connected to the power source.
•Check whether the power supply is active and that the thermostat is not
set to the STOP (0) position.
The compressor is running continuously.
•The door was opened frequently or was left open too long.
•The door is not properly closed (the door may sag or the gasket may be
dirty or damaged).
•The power supply has been interrupted for a long period of time.
•The appliance may have been overloaded with items above room
temperature.
•There may be inadequate ventilation of the compressor and condenser.
(Assure there is adequate air circulation behind the appliance and wipe
the dust from the condenser.)
Noise
Cooling in refrigeration appliances is enabled by the refrigerating system with
a compressor, which produces noise. How noisy the appliance is depends on
where it is placed, how it is used and how old the appliance is.
•During the operation of the compressor, the noise of liquid is heard and
when the compressor is not operating, the refrigerant flow is heard. This is
a normal condition and has no influence whatsoever on the lifetime of the
appliance.
•After starting the appliance, the operation of the compressor and the
refrigerant flow may be louder. This does not mean that something is
wrong. Gradually the noise is reduced.
•Sometimes a louder noise is heard, which is unusual for the appliance. This
noise is often a consequence of improper placement of the unit. (The unit
should be placed and leveled firmly on a solid base and it should not
touch the wall or cabinets standing next to it.)

Installation Instructions
Before Using Your Appliance:
•Remove the exterior and interior packing.
•Before connecting the unit to a power source, let it stand for
approximately 2 hours. This will reduce the possibility of a malfunction in
the cooling system from handling during transportation.
•Remove the shelf and clean the interior surfaces of the unit with lukewarm
water using a soft cloth.
Installing the Refrigerator/Freezer:
•Locate the unit away from direct sunlight and sources of heat (oven, heater,
radiator, etc.). Direct sunlight may affect the acrylic coating and sources
may increase electrical consumption. Extremely cold ambient temperatures
may also affect the unit's performance.
•Avoid locating the unit in moist areas. Too much moisture in the air will
cause frost to form quickly on the evaporator, requiring more frequent
defrosting of the freezer compartment.
Cable Requirements
To ensure the correct start and operating conditions for the unit, the following
cable dimensions must be observed:

Operating Your Refrigerator/Freezer
Temperature Control
•The temperature in the refrigerator compartment is controlled
with a thermostat knob located inside the unit. Turn the knob
clockwise from the STOP (0) position toward the higher numbers
for colder temperatures. Higher settings on the knob mean lower
temperatures in the refrigerator/freezer.
•In all refrigerators and freezers without interior fans, temperatures are coldest
near the bottom, and occasionally near the rear. Place contents accordingly. It
is best not to operate these units mostly empty. If temperatures are erratic, try
putting some water bottles or freezer packs inside to create a load for the
compressor.
Defrosting Your Appliance:
This appliance is a manual defrost unit. When defrosting, remove contents from
entire unit, taking care that frozen items do not begin to thaw. Set the thermostat
to STOP (0). After allowing to thaw for 20 minutes, remove any remaining ice
chunks, and turn the unit back on while you repack your frozen food back in.
CAUTION: Do not use boiling water or an electric device such as a hair dryer to
help speed up the defrosting process because this could damage the plastic parts
of the unit. In addition, never use a sharp or metallic instrument to remove frost as it
may damage the interior.
Energy Saving Tips:
•The unit should be located in the coolest area of the room, away from heat.
•Try to keep the door closed as much as possible.
•Before loading items into the unit, be sure they have cooled to ambient
temperatures.
