Dometic NDR1292-S, Installation And Operating Instructions Manual

 DC Connection

The refrigerator model NDR 1292-S require a continu-
ous 12 volt DC supply (even though 

 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 

 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

c o n d u c t o r s .
Connect 

 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 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 

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-

e r a t o r .

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 

 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 

 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 

 (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.
