Dometic RM3862 operating instructions Installing Refrigerator in Enclosure, Volts DC Connection

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.

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.

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

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.

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.

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.
