Setting the temperature
The interior temperature is regulated by an electric temperature regulator. This is located underneath
the refrigerated well and is easily accessible.
On the service side the refrigerated well is set at a temperature of 38°F. Your desired temperature
can be set by holding down the SET button (4) and simultaneously pressing UP - button (1) for higher
temperatures or DOWN - button (2) for lower temperatures.
THE DESIRED VALUE CAN ONLY BE SET WITHIN A CERTAIN RANGE
IN ORDER TO PREVENT ANY OPERATING ERRORS.
After resetting the temperature some time needs to pass before the desired temperature has been
achieved. Please check the interior temperature a few hours afterwards with an exact thermometer
and reset the thermostat if needed.
Depending on the surrounding temperature and humidity, the interior temperature is not to be set too
low as this could lead to icing on exposed areas of the cooling element. This will interfere with the
cooling performance and with the continuous defrosting which has been set by your specialized dealer
for a certain interval.

be started yet due to interlock conditions.

Lighting
External lighting of the refrigerated well can be connected to the cooling regulator and is then switched
on and off by pressing button (3).
