1 Install the door microswitch (d) at the cold room door. Install it
such that the microswitch is operated when the door is closed.
In case of cable or switch failure, the unit will react as if the door
is opened.
2 Guide the microswitch cable labelled C4 (5 m long) coming out
of the unit condenser over the roof of the cold room towards the
door microswitch (d).
NOTICE
Check the wire labels. The door heater wire is a live wire
(220-240 V), while the microswitch wire is a signal wire.
Swapping the wires will cause serious damage to the unit.
CAUTION
Do NOT push or place redundant cable length into the unit.
3 Fix the wiring to the cold room as needed.
4 Connect the wiring to the NO contact of the microswitch. When
the door is closed, the contact must be closed too.

To install the cold room lamp

The cold room lamp is controlled by the user interface. The user
interface is triggered by the cold room door microswitch (see
"5.7.1 To install the door microswitch" [ 4 15]). The lamp switches on
when the cold room door is opened and switches off when the door
is closed.
INFORMATION
This manual only describes installation instructions specific
