12 Volts DC Connection
All
refrigerator models require a continuous 12 volt DC
supply
(even though 2-way models are designed to
operate on 120 volts AC and gas, a 12 volt DC control
is required to maintain the automatic energy system).
The DC lead connections are at terminals located at the
rear of the refrigerator. (see FIG. 1). 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.
12 Volts DC Connection 3-way models
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.
Recommended wire sires are shown below.

The wires from the battery to the refrigerator must be of
large enough size to handle the toad. The connections
must be clean, tight and free from corrosion. If not, a
resulting voltage drop will cause a decreased cooling
capacity.

Securing the Refrigerator

After the refrigerator Is put in place, (ensuring a combus-
tion seal at the front frame), the refrigerator is to be
secured in the enclosure with six screws. The screws
have to be installed in the following order:
STEP1:Two screws installed through the front base,
which includes the lower front strip installation.
The refrigerator is provided with a tower front strip (ship
ped as a loose part). The front strip is to be attached after
the refrigerator is set into the cut-out opening.
1. Install the lower front strip by sliding it under the
bottom hinge plate, as shown in FIG. 5. The hinge
plate can be on
the right or left side depending on the
door swing.
