12V AND “D+” CONNECTION
The refrigerator is equipped with two terminals intended for
connection to 12 volt. One is marked “Connect to permanent
12 Volt DC house battery”and the other is marked “Connect to
Vehicle 12 Volt DC battery”, see Fig. 19.
For a Motor Home the house battery and the
vehicle battery may be the same battery.
For a caravan the 12 volt connections can only
be made to separate batteries.
CONNECTION MARKED “CONNECT TO VEHICLE 12 VOLT DC BATTERY”
This connection supplies the 12 V DC heating element.
The (+12V) and (-) poles have to be connected directly to the
vehicle battery. Via a suitable connection to the tow vehicle
when fitted to a caravan.
The (+12V) supply wire, connected to the terminal block (S)
on the wiring diagrams, has to be fused according to the
table below. Do not use the chassis for the return lead.

Before leaving, the installer should:
Check all connections for gas leaks with soap and water.
DO NOT use a naked flame for detecting leaks!
Ignite the burner to ensure correct operation of gas valve,
burner and ignition.
Instruct the user on the correct method of operation. In case
the appliance fails to operate correctly after all checks have
been carried out, contact the authorised service provider in
your area.
ELECTRICAL CONNECTION
The electrical installation must be carried out by authorised
personnel.
For mains voltage operation, it is important that
the circuit to and in the motorhome is effectively
earthed.
The refrigerator is equipped with a three-prong (grounding)
plug for your protection against shock hazards and should be
plugged directly into a properly grounded threeprong recep-
tacle. DO NOT cut off or remove the grounding prong from
this plug!
If the supply cord is damaged, it must be replaced by the manu-
facturer, its service agent or similarly qualified persons in order
to avoid a hazard.
230-240V SUPPLIES
Check that the voltage stated on the data plate is the same as
the main voltage in use (230-240V).
Electrical leads must be routed and secured so
that they cannot come into contact with hot or
sharp parts of the refrigerator.
The free length of the cord is 1 m. It is recommended that the
receptacle is located on the left side of the refrigerator (viewed
from the rear) and approximately 150 mm from the floor. This
allows easy access through the vent door. The cord should be
routed to avoid direct contact with the burner cover, flue cover
or any other components that could damage the cord insulation.
