OPERATION
Control Panel
The controls are mounted on
the back of the cabinet.
There is a power switch, a
light switch and a refrigeration
control panel.

Refrigeration
To turn the power and refrigeration on, use

Controller
Adjustment
Caution:
This controller
should only be
adjusted by a
qualified service
technician.
The controller is set up during manufacture of the cabinet, and should not
require further adjustment.
The indicated temperature is sensed by a probe in the return air, entering the
cooling coil. This is used to control the refrigeration condenser operation, and
will be marginally higher than the internal cabinet temperature.
Incorrect adjustment can cause the fins to ice up, resulting in reduced airflow
and poor performance.
The temperature of the condenser is also monitored, to protect the compressor
from damage resulting from blocked radiators etc.
The controller also governs the de-frost cycles, and incorrect adjustment can
again lead to poor temperature control or possible overflow of condensate.
If you think an adjustment may be needed, call the service technician.
