11. 12 VOLT DC CONNECTION
All refrigerator models require a DC supply to maintain the
automatic energy system). The DC lead connections are at
terminals located at the rear of the refrigerator. (See FIG. 6).
One lead is marked positive (+) and the other negative (–).
Correct polarity must be observed when connecting to the
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 DC supply.
The distance the current must travel from the battery to the
refrigerator dictates the AWG wire size to be used. Should
the wire be too small for the distance, a voltage drop will
result.
The voltage drop affects the wattage output of the 12 volt
cartridge heater and resultant refrigerator performance. Rec-
ommended wire sizes are shown below.

The wires from the battery to the refrigerator must be of large
enough size to handle the load. The connections must be
clean, tight and free from corrosion. If not, a resulting voltage
drop will cause a decreased cooling capacity. The DC supply
must be fused. The maximum fuse size is 25 amps.
Clean Direct Current (DC) power is mandatory for high-
tech circuits to operate as designed. The sources for DC
power are a battery and a converter.
A battery will provide straight line DC power, but ex-
tended operation will require recharging of the battery
by the converter or the alternator.
The converter and alternator produces DC power by a
series of diodes that rectify alternating current to DC. A
battery or capacitors can be used to clean up the AC
ripple that is present after AC voltage has been rectified.
12.INSTRUCTION FOR INSTALLING
DOOR PANEL
The refrigerator is normally delivered without the door pan-
els. Before starting the mounting work, check that the panel
dimensions are in compliance with those given in the Table
on this page and the instructions are read thoroughly. When
mounting the panel, proceed as follows. (See FIG. 8)
A. Remove the trim strip from the door by taking out the 3

screws. See FIG. 8.
B. Locate the 2 pins in the end frame of the door. If they
are in the top frame, relocate the pins into the holes in
the bottom door frame to support the panel. See FIG.
8.
C. Slide panel into grooves on vertical edges of the door
until it slips into the groove on the opposite end of door.
D. Replace trim strip and screws.

13. CHANGING DOOR SWING TO
OPPOSITE SIDE
The refrigerator is equipped with convertible doors. To
change the door swing, consult the parts manual for
the Conversion Kit Part Number. For further informa-
tion, please contact the Dometic Corporation listed on
