The flexible sealing is pressed into the groove
running around the housing. Press the side pro-
vided with the sealing knob firmly into the groo-
ve. Take care that the sealings uniformly abut
the housing.
The cavity in-between the outer vehicle wall and
refrigerator is completely isolated from the vehi-
cle interior. Intrusion of exhaust fumes into the
living space is prevented. Fumes will escape
through the upper ventilation grille to the outsi-
de. The draught-proof installation does not
require a special exhaust gas duct to be used.
Dometic recommend mounting a strip with a
heat deflector plate into the installation recess
above the appliance (Fig. 8). This allows the
ascending hot air to escape directly outside.
This deflection plate must also be provided with
a lipped seal.
That ensures that the refrigerator can easily be
removed for maintenance or repair.
Deviations require the consent of the manu-
facturer!
In the event of high ambient temperatures,
full performance of the cooling unit can only
be achieved by means of adequate ventilati-
on and extraction.
Ventilation is provided for the unit by means of
two apertures in the caravan wall. Fresh air
enters at the bottom, extracts the heat and exits
through the upper vent grille (chimney effect).
The upper ventilation grille should be positio-
ned as high as possible above the condenser
(A). Install the lower ventilation grille at floor
level of the vehicle, allowing unburnt gas (hea-
vier than air) to escape directly into the open air.
Should this arrangement prove impossible, a
ventilation aperture must be introduced by the
manufacturer of the vehicle into the recess floor
in order to avoid the accumulation of unburnt
gas on the floor (Fig. 11,12).
A correct installation of the refrigerator is essen−
tial for its correct operation, as due to physical
reasons heat builds up at the back of the appli−
ance which must be allowed to escape into the
open air.
