ADJUSTING THE TEMPERATURE CONTROL
COLDER
Adjusting the temperature control
After plugging in the units power cord set the temperature con-
trol midway between the numbers. After 2 hours adjust to the
temperature that suits you. The higher the number you select,
the cooler the temperature. (See Figure 7).
The temperature control knob is located at the bottom, front of
the cabinet, just behind the square opening near the middle of
the grille.

Defrosting Instructions
Never use a scraper or any tool that might scratch or pierce the
cooling plate. Follow these steps whenever 1/4 inch or more of
frost accumulates.
1. Disconnect the power cord and set the temperature control
knob to the “OFF” position.
2. Remove the contents from the unit.
3. Place pans of hot water on the cooling plate if you wish to
speed up defrosting.
4. Wipe out the interior and replace the contents.
5. Connect the power cord to the outlet.
6. Set the temperature control to the desired level.
In the Event of a Power Failure
Minimize the number of door openings to prevent a gradual rise
in temperature while the power is off.
NOTE: If a power interruption occurs, the unit may take five (5) to
ten (10) minutes to restart.
