12
Volts
DC Connection
The refrigerator model NDR 1292-S require a continu-
ous 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 connection is made to the positive
(t)
and
negative (-) terminals of the terminal block on the back
of the refrigerator. (See FIG. 1). 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.
Recommended wire sizes are shown below.
MAXIM”?4 TOTAL CONDUCTOR WIRE
LENGHT
(in

and
meters,
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.
INSTALLING REFRIGERATOR IN
ENCLOSURE
The transport support at the rear of the refrigerator can
be removed if necessary for the installation of the refrig-
erator in the enclosure. (See figure above).
NOTE: 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.
Caution: Use care when installing the refrigerator. This
refrigerator is equipped with the latest vacuum insulated
panel technology. These insulating panels are located
on the Top, Back, Bottom, Sides and Doors of the refrig-
erator.
If the surface is punctured, loss of insulation will occur.
resulting in poor refrigerator performance.
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, sea FIG. 4. The sealing should provide a com-
plete 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.
FIG. 4
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 straws (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 plates, as shown in FIG. 5.
