12 v DC connection
The connection is made to the terminal block marked
“12 volts DC heater”, located at the bottom left corner on the
back of the refrigerator cabinet.
The refrigerator must be connected to the battery circuit with
two wires of adequate capacity to avoid voltage drop. The
wire gauge should be chosen with consideration to the wire
length in accordance with the table below.
To ensure safe operation, the positive lead must be fitted with
a fuse rated at 20 amps. Correct polarity must be observed
when connecting to the 12 V DC supply. DO NOT use the
chassis or vehicle frame as one of the conductors. Connect
two wires at the refrigerator and route to the 12 V DC sup-
ply. The refrigerator will draw 15 amps at 12 volt DC.
The connections must be clean, tight and free from corrosion.
If not, a resulting voltage drop will cause a decreased cooling
capacity.
Note! DO NOT operate the refrigerator on 12 V when the
vehicle is parked. The amperage draw of the 12 V DC heat-
ing element can discharge a battery in a very short time. The
installation of a 12 V DC operated refrigerator requires a
relay to be installed on the tow vehicle or in the caravan. The
relay will automatically shut off the 12 V DC power to the
refrigerator when the ignition is turned off.
ChANGING DOOR SwING
The refrigerator is equipped with a reversible door. A special
door reversing kit must be used to reverse the door. For fur-
ther information, please contact your dealer.
MOUNTING ThE DOOR PANEL
The refrigerator is normally delivered without door panel
Before starting the mounting work, read this instruction thor-
oughly and check that the panel dimensions are in compli-
ance with those given in the following table:
PANEL DIMENSIONS
Max thickness 4 mm
Height Width

RM2553 983 981 527 524
To mount the door panel - with screws
Open the door 90 degrees.
Remove the door decoration
strip (2) by removing its three
screws (1).
Insert the vertical edges into
the grooves of the door
frame (3).
Push the panel downward
so that the lower horizontal edge
of the panel (4) is fitted into the
bottom groove (5).
Put the decoration strip across
the door so that the gap is
covered.
Secure the decoration strip
with the three screws removed
in step 2.
