Refrigerator; Ventilation; Protective Cover - Polar Electro 520 CTH DB 2020 Instruction Book

Concerning care and use of the refrigerator
refer to the deliver´s manual.
The manual supplied the caravan
The most caravans are equipped with a 175 liter refrige-
rator (N3175) made by Thetford. Some caravans have a
165 liter refrigerator (CR165) made by Isotherm.
All refrigerators are equipped with a freezer compart-
ment. The freezer compartment is suitable for making
ice cubes and for short-term storage of frozen food. It is
not suitable as a means of freezing foods.
The refrigerator door is equipped with a transit safety
catch, in order to lock the door before driving with the
caravan.
The refrigerator from Thetford can be operated in three
different ways: 230 V, 12 V or LPG. The refrigerator
works best if the caravan is horizontal.
The Isotherm refrigerator can only be powered by 230
V or 12 V.
The refrigerator's 12 V operation only works when the
car's engine is running and a 13-pin connector is mounted
on the car. If the 12 V operation does not work, contact
an authorized car repair shop to control that the 13-pin
connector of the car is properly connected.
∆
Check that the connection for 12 V from the
car is properly executed and working. The
refrigerator's 12 V operation only works if a
13-pin connector is mounted on the car.
∆
Don't forget to lock the refrigerator door
with the transit safety catch before driving
with the caravan.
∆
The LPG bottle must be switched off before
driving with the caravan. You are not allowed
to drive with the LPG apparatus lit.

Ventilation

In order for the refrigerator to work satisfactorily, the heat
that it generates must be removed through ventilation. In
caravans with a Thetford refrigerator, the space behind the
refrigerator is completely separated from the caravan space
and ventilated through a grille behind the refrigerator. This
grille must not be covered or blocked.
There is also a vent for refrigerator ventilation installed in
the roof. It is important to check this vent to ensure it is not
blocked by snow, leaves, etc.

Protective cover

All caravans with Thetford refrigerators are equipped with
a protective cover.
When the temperature outdoors is below + 8° C, should the
cover be mounted. The apparatus is protected in this way
against for cold air, that otherwise can affect negatively
on the apparatus function.
Install also the cover when the caravan pitched for the
winter or when washing the caravan outside.
Installing and removing protective cover
1. Remove the ventilation grille by pulling the two
locking levers laterally and folding the top of the
grille. Pull the grille downwards so that the hooks
on the lower edge release.
2. Insert or remove the protective cover and reinstall
the grille by fitting the hooks at the bottom and then
folding the grille upwards and lock it with the two
locking levers.
