We advise to install a microswitch (not supplied) on the cold room door which will
-
switch on the light in the cold room, stop the unit and
-
override the temperature alarm (for about one hour after door closing)
every time the door is opened.
The necessary cable is available with the unit. Connect it keeping in mind the following:
microswitch closed = door closed.
ATTENTION
Above microswitch is not supplied with the unit. If the microdoor cable is
disconnected or damaged, the same conditions will occur as in case of open door and
connected microdoor.
“B” RANGE units (B = low temperature) are supplied with a cable for door heater connection, to be made using
a fuse suitable for the door heater used.
The unit is also equipped with a cable for cold room lamp connection (lamp voltage should be 230 V and lamp
max capacity 100 Watts).
ATTENTION
Do not connect microdoor, cold room light or door heater cables to the 230V line.
Each cable is equipped w ith a plate show ing how it should be connected.
WARNING
Any defective electrical part should be replaced by trained personnel exclusively.
The electric connection should be effected by qualified personnel.
