Ventilation And Air Extraction Of The Refrigerator - Dometic 8 Series Installation Manual

hot air escapes through the air vent grille into
the open air. Affix the discharge plate to the
caravan wall, not to the refrigerator !
Finally, push the refrigerator into the recess from
the front. Ensure that the lipped-seals have tight
contact to the refrigerator's housing
That ensures that the refrigerator can easily be
removed for maintenance or repair.

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.
Deviations shall require the consent of the
manufacturer.

4.2 Ventilation and air extraction
of the refrigerator
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.
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 (ventilation grilles) 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 positioned as high as possible
above the cooling unit (Fig. 11). Install the
lower ventilation grille at floor level of the
recess floor (Fig. 10), allowing unburnt gas
(heavier than air) to escape directly into the
open air. The gas burner must be located
above the edge (1) .

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 accumulati-
on of unburnt gas on the floor.
The ventilation grilles must have an open
cross-section of at least 400 cm². This is
achieved by using the Dometic LS 330 absor-
ber ventilation and air extraction system which
has been tested and approved for this purpose.
