Ventilation and extraction

A correct installation is important for correct operation of the appliance to ensure,

there is no build-up of heat at the back of the appliance. This heat must be allowed

to escape 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.

The unit is ventilated through openings in the wall of the vehicle (L500). Fresh air

enters at the bottom and the warmed air flows off through the upper ventilation grille

(flue effect). The upper ventilation grille should be positioned as high as possible

above condenser (K). The lower ventilation grille should be flush with the floor of the

vehicle, allowing any gas leakages (heavier than air) to escape directly into the open

air. Should this arrangement prove impossible, a ventilation aperture must be introduced

by the manufacturer of the vehicle into the recess floor intended for the unit's installa

tion, in order to avoid the accumulation, on this floor, of any non-combusted gas which

might escape (according to EN 1949). The ventilation grilles must have a free cross

section of at least 400cm

. This is reached using the Dometic Absorber Ventilation and

Air Extraction System L500 that has been tested and approved for this purpose.

Dometic ventilation systems include installing frame, vent grille and winter cover.

The oven’s ventilation and exhaust extraction is realised with roof mounted flue outlet

only (Truma- roof flue outlet).

Correct mounting of the lower

access to the electrical and

gas connections during main-

tenance work.
