8.4 Decommissioning of the Refrigeration unit
The unit should be taken out of service by disconnec-
tion the mains plug if a lengthy downtime, cleaning or
maintenance work is projected. A short-term decommis-
sioning of the Refrigeration unit can be undertaken by
depressing the Start/Stop key for approx. 3 sec. (Standby
mode).
The Refrigeration unit and its connected loads are not
potential-free in the Standby mode.
Note:
The set parameters will retain their setting following an
interruption of power.
Attention!
If the unit is taken out of service and is to be stored
in an area, in which a frost hazard exists, it must be
ensured that the heat exchanger water has been
completely drained, as this unit can otherwise be
destroyed.
This is possible by loosening the lower bolting on the
condenser unit.
