At extreme ambient temperatures the refrigeration unit
will only perform adequately when properly ventilated.
Side ventilation
The refrigerator unit is ventilated via two openings in the
wall of the caravan (fig. 6b).
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.
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 caravan and one on the
roof for the roof vent (fig. 6a).
Fresh air enters through the lower opening and warm air
is discharged through the roof vent.
Ventilation grilles
We recommend fitting the Dometic ventilation system,
which is specially developed by Dometic for this purpose.
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 vehicle.
The flue gases are dispersed through the upper vent
grille or the roof vent together with the ventilation air.
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 2.7 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.
CAUTION! Check that the gas supplied to the
refrigerator is at the correct pressure. See the
reducing valve on the LP gas container.
The gas installation and servicing must be carried out by
an authorised person and conform to all relevant local
authorities.
The gas supply system must incorporate an approved
gas pressure regulator to maintain a supply pressure of
2.75 kPa.
NOTE: Wood Strip
MUST be in place
