E1.3 Ventilation And Air Extraction - Dometic RM 8400 Installation Instructions Manual

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

E1.3 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-
In the event of high ambient temperatures, full performance of the cooling unit can
only be achieved by means of adequate ventilation 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
require a special exhaust gas duct to be used.
This installation method allows the use of the
same air vent grille L200 at the top and at the
bottom without flue duct.
If a flue duct is nevertheless desirable, incorpo-
rate the L100 ventilation system with flue duct
into the upper air vent opening. ( For installation,
please refer to "E1.7" )

level of the vehicle, allowing unburnt gas (hea-

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.
