Installation Manual 8
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.
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.
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.
