4.2

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 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
condenser (A, Fig. 18, 22). Install the lower
ventilation grille at floor level of the vehicle,
allowing unburnt gas (heavier than air) to esca-
pe directly into the open air. An optional venti-
lation aperture can 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.18).

4.3 Installing the ventilation
system
4.3.1 Ventilation systems for small
refrigerators (120 ltr. cap. or less)
Dometic recommends the A 1625 ventilation
and flue gas extraction system which has
been tested and approved for this purpose.
These ventilation grills provide the required
open cross-section of at least 250 cm².
