5 Intended use
The refrigerators RM122 and RM123 are designed for installation in cara-
vans or motorhomes. They are suitable for cooling foodstuffs.
The refrigerators are designed for operation on a 12 Vgvoltage source and
can be independently powered by liquefied petroleum gas (propane or bu-
tane). The refrigerator RM123 is also designed for connection to a mains
voltage of 220–240 Vw.
6 Technical description
6.1 Description
The refrigerator is an absorption refrigerator. The device is designed to oper-
ate with different types of energy and can be operated as follows:
RM122: with 12 Vgor butane/propane gas
RM123: with 220–240 Vw, 12 Vgor butane/propane gas
The device has a locking mechanism to protect it during transport.
The unit is equipped with an automatic flame failure device which automati-
cally interrupts the gas supply after approx. 30 seconds if the flame goes out.

7 Installing the refrigerator
7.1 Preparing the installation
Observe the following instructions when installing the refrigerator:
The refrigerator should not exceed an angle of inclination of 3° so that the
refrigerant can be circulated properly. Make make sure that the ice tray is
flat in the refrigerator when the vehicle is level.
The refrigerator must be installed in a recess so that it remains fixed in
place during movement of the vehicle. Mind the following dimensions:
(HxWxDinmm):662x384x415.
All surfaces around exhaust pipe and burner housing must be of or cov-
ered by metal or other non-flammable material.
In the outer wall an air inlet (fig. 31, page 3) and vent hole (fig. 32,
page 3) with ventilation grid has to be provided so that emerging heat can
be properly dissipated to the outside:
– air inlet: ventilation grid as flush as possible to the floor of the fitted
niche with a cross-section of at least 250 cm²
– vent hole: preferably atop the device. Here a ventilation grid with inte-
grated exhaust gases duct can be used instead.
If the air inlet‘s ventilation grid cannot be mounted flush to the floor, an
additional air inlet (fig. 34, page 3) must be provided in the floor to dis-
charge leaking gas.
The air inlet and the vent hole must not be covered by vehicle compo-
nents (e.g. bumper or open door) during operation.
At the back of the refrigerator must be enough space so that air can
circulate around the cooling element.
Provide a heat conducting plate on the upside (fig. 31, page 3) so that
heat cannot build up inside the vehicle.
The refrigerator must be installed draught-proof according to EN 1949,
see chapter “Installing the refrigerator draught-proof” on page 15.

EN
RM122, RM123 Installing the refrigerator
15
7.2 Installing the refrigerator draught-proof
Gas powered cooling devices in caravans and motorhomes must be installed
draught-proof according to EN 1949. This means that the combustion air
won‘t be taken from the interior room and that the exhaust gases are
prevented from direct entry to the living space.
A suitable sealing between the backside of the refrigerator and the interior of
the vehicle must be provided.
!
The manufacturer recommends using a flexible seal to simplify the assembly
and disassembly for maintenance.
➤Fix the lip seals (fig. 41, page 3) to a stop bar behind the refrigerator,
e.g. by gluing.
➤While mounting push the refrigerator against the stop bar with the lip
seals. Thereby the area behind the device is sealed towards the interior
of the vehicle.
7.3 Making air inlet and vent hole
I
➤Produce an air inlet and a vent hole in the outer wall. Observe the follow-
ing instructions, see chapter “Preparing the installation” on page 14.
If the air inlet‘s ventilation grid cannot be mounted flush to the floor of the fit-
ted niche, you must install an air inlet in the floor:
➤Make a vent opening of a diameter of at least 40 mm on the ground be-
hind the refrigerator in the area of the gas burner (fig. 51, page 4). The
vent pipe must be routed directly to the outside. So leaking unburnt gas
can escape to the outside.
➤Shield the end of the opening with a deflector to prevent it from mud or dirt
while driving (fig. 6, page 4).
WARNING! Fire hazards!
Do not use easily inflammable materials such as silicone
sealants, installation foam, etc. for the draught-proof installation.
NOTE
At high ambient temperatures the refrigerator can only generate
its maximum cooling capacity if a optimal ventilation and
de-aeration is provided.

7.4 Fixing the refrigerator
➤Fix the refrigerator using blocks of wood laterally:
Fix the blocks of wood on the side of the recess from the front to the back
(fig. 81, page 5).
7.5 Installing exhaust pipe
The exhaust pipe must lead the exhaust gases directly to the outside.
➤Make an opening with a maximum diameter of 70 mm at the opening in
the vehicle wall.
➤Put the T-piece (fig. 92, page 5) on the opening of the refrigerator.
➤Lead the extension tube (fig. 91, page 5) of the venting kit outside
through the opening.
The vent cover must touch the outer wall of the vehicle. If this is not the
case, you have to shorten the extension tube (fig. 91, page 5).
A
I
To shorten the extension tube, proceed as follows:
➤Insert extension tube (fig. 91, page 5) and tail (fig. 92, page 5) into
each other.
➤Measure the area between the vent cover and outer wall (fig. 0X,
page 5).
➤Transfer the measurement to the end of the extension tube (fig. 0Y,
page 5).
➤Shorten the extension tube accordingly.
➤Secure the end with the opening of the refrigerator with a screw (fig. 9,
page 5, ).
NOTICE! Risk of damage!
Do not extend the exhaust pipe, otherwise the water vapour con-
denses in the exhaust pipe and runs back into the unit. The burner
can be damaged.
NOTE
If the vehicle wall at the outlet of the exhaust pipe is not vertical or
flat, you have to fill the feed cover plate below with a non-combus-
tible material. The cover plate must be parallel to the back wall of
the refrigerator.

EN

➤Seal the hole with non-flammable sealant (fig. a1, page 5).
➤Fix the cover plate with four screws on the outer wall of the vehicle
(fig. 93, page 5).
7.6 Installing cover plate above the refrigerator door
➤Screw a block of wood on each side with the dimensions 25 x 66 mm on
both sides of the recess.
➤Mount the blocks 16 mm offset inwards, so that the cover plate flush with
the front of the kitchen furniture (fig. 82, page 5).
➤Screw the cover plate on the blocks.
7.7 Reversing the door hinge
A
The refrigerator is delivered with the door hinge on the right. This is how to
reverse the door hinge:
➤Turn the refrigerator on the side.
➤Pull the knob of the temperature switch.
➤Loosen the two screws and remove the lower cover plate.
➤Remove the top hinge leaf and the closure plate.
➤Hold the upper hinge leaf and the closure plate to the desired side and at-
tach it to the lower hinge leaf from the opposite side.
➤Install the vent grille with the two screws.
➤Press the knob of the temperature switch to the spindle so that it is fixed
in the recess.
➤Wait a few hours before starting the refrigerator.
NOTICE! Risk of damage
Lay the refrigerator on the side only, never on the backside.
Otherwise the aggregate may be damaged.
