Error Codes
Error codes indicate when the controller is sensing a
problem. A description of each is given below. See the
Troubleshooting Table for additional information on error
codes.
E1
Open sensor.
E2
Under temperature. Temperature at sensor is
less than -36°C.
E3
Over temperature. Temperature at sensor is
greater than 37°C.
Interior Lights
The interior lighting automatically turns on when the door
is opened. If the interior lamp fails, replace with the same
size and wattage lamp. DO NOT USE REDUCED
WATTAGE LAMPS. The reduced wattage lamps general-
ly fail to light below 60°F (15°C). All replacement lamps
should be plastic coated.
Cabinet Cleaning
The cabinet interior should be cleaned frequently. Any
spilled liquid should be wiped off immediately. Stains
resulting from some spills can be permanent if not quickly
removed. The cabinet exterior should be cleaned occa-
sionally. A mild detergent and lukewarm water or a solu-
tion of bicarbonate of soda (1 tablespoon per gallon of
water) is recommended for cleaning the interior and exte-
rior of the cabinet. All surfaces should be rinsed and thor-
oughly dried.
Cleaning the Condenser
For efficient operation, it is recommended that the con-
denser coil and fan be cleaned every 4 to 6 months. The
condenser coil is located behind the vented part of the
header panel (left side). Remove the header panel for
access. Vacuum clean the front surface of the coil thor-
oughly, or direct forced air through the condenser from
the rear. If necessary, use a stiff bristled brush to loosen
any dirt. The failure to clean the condenser voids the
warranty.
Maintenance and Servicing
Caution
When servicing the unit, disconnect
plug from the electrical power source.
Caution
Do not use any type of abrasive such
as steel wool or fluids, such as gaso-
line, Naptha or paint thinner. These
materials could be harmful to plastic
materials, door gasket and painted sur-
faces.
Caution
Accessing and cleaning the conden-
sate coil or pan should be done by
qualified personnel.
