Ventilation And Air Extraction Of The Refrigerator - Dometic RMF8500 Installation Manual

Installation
4.2 Ventilation and air extracti-
on 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.
i
In the event of high ambient temperatures,
full performance of the cooling unit can
only be achieved by means of adequate
ventilation and extraction.
4.2.1 Principle of ventilation
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).
Principle of ventilation / example with ventilation grilles
Principle of ventilation / Alternative : example with roof exhaust

4.2.2 Good and bad ventilation
i
Avoid installations marked with the
bol. Good cooling performance is not gua-
ranteed!
(schematic figures)
The installation of a heat deflection plate (1)
between the refrigerator top edge and the
ventilation grille top edge is strictly requi-
red to guarantee the dissipation of the unit
heat and thus prevent heat build-up.
