Installation and Owner’s Manual 14
- Make sure that the materials used for the gas supply line
obey both the current ANSI A 119.2 (NFPA 1192) and CSA
Z240 Standards on Recreational Vehicles. Norcold
recommends the use of 3/8 inch copper tubing as the gas
supply line and requires a 3/8 inch SAE (UNF 5/8-18) 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 to
allow clearance for the gas supply line.
- Put a weather resistant seal (grommets, 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 [2] of the
refrigerator (See Art01035).
Examine the gas supply system for leaks:
WARNING: Do not allow the leak detecting solution to
touch the electrical components. Many liquids are
electrically conductive and can cause a shock hazard,
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 shutoff
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 manual shutoff valve 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
shutoff valve of the refrigerator before the test.
This refrigerator operates on propane gas at a pressure of 11
inches Water Column Propane.
Connect the propane gas supply system:
WARNING:
Be very careful when working on or near the
propane gas supply 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 gas tank without
a pressure regulator between them.
- To avoid possible propane gas leaks, always use two
wrenches to tighten or loosen the 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 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
CAN 1-6.10 Standard.
Connect the Propane Gas Components
- The voltage drop will reduce the cooling performance of the
refrigerator.
The terminals for connecting the DC power supply are marked
positive (+) and negative (-) on the terminal block of the refrig-
erator. Make sure that:
- Each DC power supply wire is attached to the correct
polarity wire.
- The chassis or the vehicle frame is not used as one of the
conductors.
- The DC power supply wires including the fuses are routed
directly from the battery to the refrigerator.
2. Connect the D.C. power supply wires:
- Attach a 1/4 inch female Quick Connect terminal to each DC
power supply wire.
- Push each power wire onto the terminal block [1] at the rear
of the refrigerator (See Art01035).
- Make sure each DC power supply wire is on the correct
polarity terminal.
