Control Elements and Safety Devices
1. On-off switch
at the front
2. Cut-out of machine when storage bin is full:
ZBE 30 - ZBE 110:
Thermostat in bin
The thermostat switches the machine off when the bin is full
and on again when ice has been removed.
The switch-off point is adjusted for longer ice contact,
not for a momentary contact.
The thermostat does not operate at temperatures below +5° C
For such applications ask for special execution.
ZBE 150 - ZBE 375:
switch the machine off, when ice dams up
in the ice discharge hose and when the bin is full.
Special models:
e.g. for sauna, on request
3. Water pressure switch or Water level control
switch the machine off in case of too low water
pressure or water shortage.
Automatic restart when the water supply
has been restored.
4. Compressor
Automatic motor cut-out in compressor connecting box.
5. High pressure switch
The machine is switched off, if there is e. g. excess
in the refrigeration system caused by too high
ambient temperature or soiled condenser.
6. Gear Motor
Overload cut-out in switch box.
7. Automatic water drain
(not provided in all machines)
In order to reduce nucleation in stagnant water, a solenoid
valve closes the water inlet as soon as the machine
is out of operation, another opens the water drain
thus emptying the water chamber and the freezing unit.
8. Capacity control
(ZBE 350 and ZBE 375):
The capacity control protects the evaporator and
the compressor against overburdening by too
low ambient- or watertemperature.

Automatic restart after removal of ice.
