7.2 Installing the refrigerator draught-proof
Gas powered cooling devices in caravans and motorhomes must be as draught-
proof installed according to EN 1949. This means that the combustion air won‘t be
taken from the living space and that the exhaust gases are prevented from direct
entry to the living space.
A suitable sealing between the back of the refrigerator and the interior of the vehicle
must be installed to room seal the back of this device.
!
The manufacturer recommends using a flexible seal to simplify the assembly and dis-
assembly for maintenance.
Fix the lip seals (fig. 5 1, page 4) to both side walls at the back of the refrigera-
tor.
Stick the inflammable foam tape on the top of the refrigerator and on the bottom
of the extension cover plate (fig. 5 2, page 4).
7.3 Making air inlet and vent hole
I
Produce an air inlet and a vent hole in the outer wall. Observe the following
instructions, see chapter “Preparing the installation” on page 14.
If the air inlet's ventilation grille cannot be mounted flush to the floor of the fitted
niche, you must install a gas drop hole in the floor:
Make a vent opening of a diameter of at least 40 mm on the ground behind the
refrigerator in the area of the gas burner (fig. 3 1, page 3). The vent pipe must
be routed directly to the outside, so any leaking unburnt gas can escape to the
outside.
Shield the end of the opening with a deflector to protect it from mud or dirt while
driving (fig. 6, page 4).
WARNING! Fire hazards!
Do not use easily inflammable materials such as silicone sealants, instal-
lation foam, etc. for the draught-proof installation.
NOTE
At high ambient temperatures the refrigerator can only generate its
maximum cooling capacity if optimal ventilation and de-aeration are pro-
vided.
