Ventilation

4.3.1 Ventilation and air extraction of
the refrigerator
A correct installation of the refrigerator is
essential for its correct operation, as due to
physical reasons heat builds up at the back of
the appliance which must be allowed to esca-
pe 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
ventilation and extraction.
Ventilation is provided for the unit by means of
two apertures (ventilation grilles) in the cara-
van wall. Fresh air enters at the bottom,
extracts the heat and exits through the upper
vent grille (chimney effect). The upper venti-
lation 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. 16), allowing
unburnt gas (heavier than air) to escape direct-
ly 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 accumula-
tion 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 300 absor-
ber ventilation and
which has been tested and approved for this
purpose.

duct to vehicle's interior

4.3.2.1 Ventilation to vehicle's interior

(special equipment, model without
flue)
If ventilation and exhaust duct into the vehicle
is intended, fresh air supply must not be
obstructed. The room in which the device is
installed must have one or several openings
allowing fresh air to enter (safety ventilation
according to EN 721). These openings must
have a total cross section of at least 100
cm². There must be one or several ventila-
tion openings above the device with mini-
mum cross sections of 150 cm². These have
to be checked and if necessary cleaned regu-
larly. Roof and wall outlet openings can be
combined. Lower ventilation openings must
be no more than 100 mm above the inside
floor. The ventilation openings must by no
means be shut. Grilles and covers must be
kept clean and free of dust.
