5 Installation
5.7.3
To install the door heater
For low temperature applications it is suggested to install a door
heater. It prevents the door from freezing solid.
The choice for the most appropriate door heater is left to the installer
or cold room manufacturer.
NOTICE
The door heater must be suitable for 220-240  V, and the
total load of the control circuit must NOT exceed 5 A.
INFORMATION
The door heater (commercial type) usually has an electric
current of 0.4/0.5 A (depending on the length of the wiring),
with a maximum of 0.7 A.
INFORMATION
This manual only describes installation instructions specific
to this unit. For carrying out mechanical work on the cold
room, the instructions of the cold room manufacturer must
always be followed.

1 Install the door heater (d) at the cold room door opening.
2 Guide the door heater cable labelled C2 (5 m long) coming out
of the unit condenser over the roof of the cold room towards the
door heater (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 wires to the door heater.

See "5.3 Opening and closing the unit" [ 4  10].
Three cable glands (a, b and c) are provided to bring option cables
into the unit.
2 Guide the cable towards the cable gland, and into the unit.
Secure the cable into the cable gland.
