Operating Procedure

Power Source: Insert the plug of the refrigerator into the outlet provided in the end

panel of the Prep Table. The unit consists of one compressor. Other motors and
heavy appliances should not be used on the same circuit with the refrigerator.

Start-Up: The refrigerator is turned ON by plugging the cord into the outlet and check if

the condenser fan is running. Let the unit run for 1 hour before placing product in
the refrigerator.

Temperature Setting: The unit has been tested at the factory and the thermostat has

been preset to maintain a temperature between 33 and 40°F (1 and 5°C).

Thermostat Adjustment: If the unit does not hold the desired temperature, the

thermostat can be adjusted. For colder temperatures, turn knob clockwise. For
warmer temperature setting, turn knob anti-clockwise. Wait for 1 hour before
readjusting the thermostat. Excessive tampering with the thermostat may lead to
operational difficulties.

5. Condensate Disposal: The condensate from the refrigerator is disposed via a drain
to a condensate evaporator located in the base of the condensing unit.
