Cold room lamp
The lamp is ON when the cold room door is open. It is controlled by
the user interface. The cold room lamp is an accessory. See
"5.7.2 To install the cold room lamp" [
4
16].
INFORMATION
As there are only 3 free cable glands, only 3 more options
can be installed.
Alarm
An alarm feature can be installed (light or sound). See "5.8 To
connect an alarm signal" [

Router
The unit (or multiple units) can be connected to the internet through
a router, available as an option. See
"5.9 To connect a
router" [

5 Installation
5.1 General installation guidelines
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.
INFORMATION
Make sure that the unit is not exposed to direct sunlight.
Blocking sunlight increases the cooling effect.
INFORMATION
Do not expose the unit to a saline environment (e.g. sea
breeze atmosphere). This to prevent corrosion caused by
high levels of salt in the air, which can shorten the life of
the unit.
If outside air is sucked into the cold room, the temperature may rise,
and condensation (and ice formation) may occur on the surface of
the unit evaporator.
Therefore:
▪ Don't install the unit with openings right in front of it (A, B).
▪ Avoid a Venturi effect created by the airstream (C). Install the
door-opening in the direction that minimises this effect (D).
▪ Install the unit as far away as possible from openings that allow
outside air to enter, such as doors and pressure regulating valves
(E, F).
INFORMATION
Although it is advised to place the unit as far away from the
door as possible, this is not mandatory. The presence of
the door micro-switch, that interrupts operation when the
door is open, limits the in- and outgoing airflow.

A typical installation is shown below. Installing the unit (a) in this way
ensures efficient operation and good cold air circulation.

If possible, provide an anteroom in the cold room. This prevents the
cold air from flowing out of the freezer.
It also prevents the inflow of moist containing outside air, causing
condensation (and ice) on the surface of the unit evaporator.
If an anteroom room is not provided, an air curtain or a vinyl curtain
can be used to limit the inflow of outside air.
