installation procedure

9.Put back the cover.

10.Press the ON/OFF button off and then back on. Nor- mal operation of the burner should return.

11.Allow the burner to operate for a minimum of five minutes.

To test the gas safety shut off, follow these steps:

1.Start the refrigerator without connecting to

120V AC.

2.Check that the gas flame is lit. In AUTO mode, the AUTO mode indicator lamp is on.

3.Follow steps 3-11 in the previous instruction.

Electrical connection

120 V AC connection

The refrigerator is equipped with a grounded three-prong plug for protection against shock hazards. It should be plugged di- rectly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug!

The free length of the cord is 2 feet. It should be routed to avoid direct contact with the burner cover, flue cover or any other components that could damage the cord insulation.

To allow easy access through the vent door, it is recommended that the receptacle is placed like this:

12V DC connection

RM2451, RM2551, DM2652 & DM2852: These refrigerator models are not designed for 12V DC operation of the cooling system. However, 12V DC must be supplied to operate the controls.

RM2354, RM2454, RM2554, DM2662, DM2663, DM2862, DM3862 & NDM1062: These refrigerator models require a continuous 12V DC supply to maintain the automatic energy system.

The connection is made to the positive (+) and negative (-) terminals of the terminal block on back of the refrigerator.

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. Ensure the connections are clean, tight and free from corrosion.

Ensure that the wires from the battery to the refrigerator are able to handle the load. The distance the current must travel from the battery to the refrigerator dictates the AWG wire size to be used. Inadequate wire sizes can result in a voltage drop which affects the refrigerator performance.

For 3-way models, the voltage drop affects the wattage output of the 12V cartridge heater and the refrigerator performance. The 12V DC heater is fused with a 30 amp. in-line blade fuse.
