12 Volts DC Connection

The refrigerator models NDR 1492-S and NDR 1492-B

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 connection is made to

the positive (+) and negative (-) terminals of the terminal

block on the back of the refrigerator. (See FIG. 1). Cor-

rect 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.

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, see 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.

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.

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 plates, as shown in FIG. 5.
