NOTE: Do not use the chassis of the refrigerator or the vehicle frame as one of the conductors. Attach the DC power supply wires only to the battery and the power board [1] of the refrigerator.

-Push the positive DC power wire [2] onto the power board terminal that is marked 12VDC.

-Push the DC ground wire [3] onto the power board terminal that is marked GND1 .

-Make sure each DC power supply wire is on the correct polarity terminal.

Connect the Propane Gas Components

Propane Gas Operation

Propane gas

(11 inches water column pressure)

12 volts DC control voltage

(10.5 volts min. - 15.4 volts max.).

This refrigerator operates on these energy sources. Operation out of these limits can damage the refrigerator electrical circuit parts and will void the warranty

Connect the propane gas supply system:

WARNING: Be very careful when working on or near the propane gas system.

-Do not smoke, or use an open flame near the propane gas system.

-Do not use an open flame to examine for leaks.

-Do not connect the refrigerator to the propane gas tank without a pressure regulator between them.

-To avoid a propane gas leak, always use two wrenches to tighten or loosen the propane gas supply line connections.

-Leaking propane gas can ignite or explode and result in dangerous personal injury or death.

Connect the gas supply line to the refrigerator:

-Make sure that all tubing and fittings obey all local, state, and national codes about size and type.

-Make sure that all flexible metal connectors obey the current CAN1-6.10 Standard.

-Use 3/8” diameter copper tubing as the propane gas supply line and use a 3/8” SAE (UNF5/8 -18) male flare fitting as the connection to the refrigerator.

-Put the propane gas supply line up through the floor of the enclosure.

-Make sure the hole through the floor is large enough allow clearance for the gas supply line.

-Put a weather resistant seal (grommet, sealant, etc.) around the gas supply line where it goes through the floor to prevent vibration and abrasion.

-To prevent vibration and abrasion, make sure that the gas supply line is not against anything in the enclosure.

-Attach the gas supply line to the bulkhead fitting of the refrigerator.

Examine the propane gas supply line for leaks:

WARNING: Do not allow the leak detecting solution to touch the electrical components. Many liquids are electrically conductive and can cause electrical shorts and in some cases, fire.

Use a leak detecting solution to examine the gas supply line and all propane gas connections for leaks.

If you use compressed air for the test:

-The pressure of the compressed air at the manual shut off valve of the refrigerator must not be more than 1/2 psig (14 inches Water Column).

-If the pressure of the compressed air is more than 1/2 psig (14 inches Water Column), remove the gas supply line from the bulkhead fitting of the refrigerator before the test.

-If the pressure of the compressed air is equal to or less than 1/2 psig (14 inches Water Column), close the manual shut off valve of the refrigerator before the test.
