The Dometic ventilation grilles permit inspection and

small repairs to be carried out without the necessity of

removing the refrigerator from the recess.

If there is no outer grille at floor level where leaking gas

can escape, a 40 mm hole to the outside should be made

in the floor of the recess to drain any unburned gas to

the outside. Fit the hole with wire mesh and an angled

plate to protect it from stones, mud etc.

Removal of flue gases

The ventilation passage at the rear of the recess, be-

tween the outer wall of the vehicle and the refrigerator

must be sealed off against the living space, so cold

draughts are excluded (winter camping) and no flue

gases can penetrate into the motorhome.

The flue gases are dispersed from the ventilation pas-

sage using the Dometic flueing system.

The top, bottom and sides of the ventilation passage

should be insulated to prevent condensation and cold

draughts.

LP GAS CONNECTION

The refrigerator is designed for operation on LP gas, the

pressure of which must be 2,75 kPa for Propane.

Check that this is stated on the data plate.

The refrigerator is not designed for operation on

town gas or natural gas.

VENTILATION OF THE UNIT

Ventilation heights

At extreme ambient temperatures the refrigeration

unit will only perform adequately when properly ven-

tilated.

Side ventilation

The refrigerator unit is ventilated via two openings in the

wall of the motorhome (fig. 7b).

Fresh air enters through the lower opening and warm air

is discharged through the upper one.

The lower opening should be located at floor level (to

allow any leaking gas to escape to the outside).

The upper ventilation opening should be located above

the condenser, as high as possible, to ensure good ven-

tilation.

Roof ventilation

The ventilation of the cooling unit can also be done via

one opening in the wall of the motorhome and one on

the roof for the roof vent (fig. 7a).

Fresh air enters through the lower opening and warm air

is discharged through the roof vent.

The lower opening should be located at floor level (to

allow any leaking gas to escape to the outside).

Ventilation grilles

We recommend fitting the Dometic ventilation system,

which is specially developed by Dometic for this purpose.
