Internal cooling
On the “internal cooling” version, the cooling unit is installed in cas-
ing mounted on the back wall. The internal cooling unit is supplied
with power directly via the equipment. The cooling liquid circulates
in a closed circuit.
Cooling is activated automatically, if this is necessary to reach the
entered setpoint for the temperature. To protect the compressor
from overloading, it switches on with a time delay of up to three
minutes in the following situations:

After activating the “Temperature” parameter

After the door was opened and closed again while cooling is
active.

After automatic reactivation after a power failure.
External cooling
In the “external cooling” version, the cooling unit of an in-house
cooling system is supplied with cooling liquid. To this end, the
equipment has a cooling register with a controlled magnetic valve.
The magnetic valve opens as required and lets cooling liquid pass
through
the cooling register.
To let cooling liquid in and out, the back wall of the equipment fea-
tures two plug-in sleeves for hoses with an exterior diameter of 10
mm. The connections are labelled “Cooling water in” (inlet) and
“Cooling water out” (outlet). The connection pressure at the inlet of
the cooling medium may be up to 0.7 bar, the outlet should be de-
pressurised.
INFORMATION
For information on the technical data for the cooling system, see
chapter 12.3.2 "Temperature Parameter", page 84.
