12 Volts DC Connection
This refrigerator model require a continuous 12 volt DC
supply to maintain the automatic energy system.
The connection is made to the positive (+) and negative (-)
terminals located at the rear of the refrigerator. (See
FIG. 1). Correct polarity must be observed when con-
necting 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 model
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.
The 12 volt DC heater is fused with a 30 amp. in-line fuse.
Recommended 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.
INSTALLING REFRIGERATOR INENCLOSURENOTE: DO NOT install the appliance directly on
carpeting. Carpeting must be removed or
protected by a metal or wood panel beneath
the appliance, which extends at least full
width and depth of the appliance.
NOTE: A wood strip must be in place across the upper
opening of the enclosure. The top frame of the refrigera-
tor will be anchored to the wood strip with screws.
See FIG. 10.
The refrigerator must be installed in a substantial enclo-
sure and must be level. When installing the refrigerator
in the enclosure, all areas within the recess in which the
refrigerator is installed must be sealed.
Make sure that there is a complete seal between the
front frame of the refrigerator and the top, sides and
bottom of the enclosure. A length of sealing strip is ap-
plied to the rear surface of the front frame for this pur-
pose, see FIG. 4.

The sealing should provide a complete isolation of the
appliance’s combustion system from the vehicle interior.
NOTE: Be careful not to damage the sealing strip when
the refrigerator is put in place.
Securing the Refrigerator
After the refrigerator is put in place, (ensuring a com-
bustion seal at the front frame), the refrigerator is to be
secured in the enclosure with six screws (not included).
The screws have to be installed in the following order:
STEP 1: Two screws installed through the front base,
which includes the lower front strip installation.
The refrigerator is provided with a lower front strip
(shipped as a loose part). The front strip is to be attached
after the refrigerator is set into the cutout 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.
