Side Installation With Floor-Roof Ventilation; Rear Installation - Dometic RM8 Serie Montageanleitung

4.1.2 Side installation with floor-roof
ventilation
Proper ventilation of the refrigerator can also
be achieved by lower air intake aperture in the
floor and upper roof exhaust vent (see Fig. 7).
A flue has to be provided between the top
edge of the refrigerator and the roof ventilation
which directs the hot air and the exhausts
straight to the air vent in the roof.
The floor opening must have a cross section of
at least 250 cm² . Protect the opening, e.g.
with a baffle plate and a net, to prevent dirt
from entering the gas burner. Compared to
side ventilation, this ventilation method can
allow more dirt to enter the rear area of the
refrigerator, which makes regular maintenance
of the gas burner, at least once a year, neces-
sary.
Recommendation:
Roof vent
R500
hot air
condenser
floor opening:
at least 50 mm wide,
at least 520 mm long

With this installation method, regular main-
tenance of the gas burner is only possible
once the device has been dismantled. It is
imperative that the refrigerator be installed
in a way to allow easy removal.
We therefore recommend providing an ade-
quate access opening (service flap) for
ready serviceability from the outside.

4.1.3 Rear installation

Rear installation often causes an unfavourable
installation arrangement, as ideal ventilation
cannot always be assured (e.g. the lower ven-
tilation grille is covered by the bumper or the
rear lights of the vehicle!) (Fig. 8). The maxi-
mum cooling performance of the aggregate is
actually not available.

Another unfavourable method of rear installa-
tion is to install the air intake and exhaust gril-
les (Fig. 10) at the side wall of the recreation
vehicle. The air-heat recirculation is very
restricted which means that heat exchangers
(condenser, absorber) cannot be adequately
cooled. The optional method of an additional
air vent grille installed in the floor also exhibits
an insufficient air flow duct.
