Dometic RM2354 manual Testing Lp Gas Safety Shutoff, ELECTRICAL CONNECTION 120 Volts AC Connection

TESTING LP GAS SAFETY SHUTOFF

The gas safety shutoff must be tested after the re- frigerator is connected to the LP gas supply.

To test the gas safety shutoff, proceed as follows:

1.Start the refrigerator and switch to GAS mode. (See start up instructions).

2.Check that the gas flame is lit and the GAS mode indicator lamp (C) is on.

3.Close the manual gas shutoff valve at the back of the refrigerator. (See FIG. 1).

4.Wait for one minute. The CHECK indicator lamp (E) should be on and the GAS mode indicator lamp (C) should be off.

5.Remove protection cover (see FIG. 1) and open the manual gas shutoff valve. Do not change any button positions on the control panel. Apply a non-corrosive commercial bubble solution to the burner jet orifice.

6.No bubbles should appear at the opening of the burner jet orifice. The presence of bubbles indicates a de- fective gas safety shutoff, and service is required.

7.If no bubbles were present at the burner jet orifice, it should be rinsed with fresh water. Be careful not to damage the burner jet orifice. Replace cover and press the main power ON/OFF button (1) OFF and back ON. Normal operation of the burner should re- turn. Allow the burner to operate for a minimum of 5 minutes.

ELECTRICAL CONNECTION

120 Volts AC Connection

The refrigerator is equipped with a three-prong (grounded) plug for protection against shock hazards and should be plugged directly 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. and therefore recommended that the receptacle be located to the left side of the refrigerator (viewed from the rear) and approximately 4-6 inches from the floor (see FIG. 8). This allows easy accessibility through the vent door. The cord should be routed to avoid contacting the burner cover, flue cover, or any other components that could damage the cord insulation.

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 of the terminal block on back of the refrig- erator. (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.

The voltage drop affects the wattage output of the 12 volt cartridge heater and resultant refrigerator performance. The 12 volt DC heater is fused with a 30 amp. in-line blade fuse.

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. If not, a resulting voltage drop will cause a decreased cooling capacity.
