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-

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.
