Installation and Owner’s Guide 8
Reinstall the Refrigerator
WARNING: Make sure the seal strips [28] (See
Art00951) are not broken, are completely around
the refrigerator mounting flanges, and are between
the refrigerator mounting flanges and the wall of the
enclosure. If the seal is not complete, exhaust fumes can
be present in the living area of the vehicle. The breathing
of exhaust fumes can cause dizziness, nausea, or in
extreme cases, death.
1. Push the refrigerator completely into the enclosure.
2. Put the screws though the mounting flanges and into the wall.
3. Put the plastic plugs into the mounting flanges of the
refrigerator.
CAUTION: The rear of the refrigerator has sharp edges
and corners. To prevent cuts or abrasions when working
on the refrigerator, be careful and wear cut resistant
gloves.
4. Open the lower intake vent and put the screws through
refrigerator and into the floor.
WARNING: To avoid possible gas leaks, always use two
wrenches to tighten or loosen the propane gas supply line
connections of the refrigerator.
5. Attach the propane gas supply line to the bulkhead fitting of
the refrigerator.
6. Open the valve at the propane gas tank(s).
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.
7. Examine the gas supply line for leaks.
8. Connect the DC wiring to the refrigerator:
- Install the DC fuse or connect the DC wiring to the battery or
the converter.
- Mark the DC wires so you can put them back in the correct
location.
- Remove the DC wiring from the refrigerator.
4. Remove the screws which fasten the rear of the refrigerator to
the floor.
5. Remove the screws which fasten the refrigerator to the wall.

Refrigeration Failure
If the refrigerator does not cool, it does not mean that the cooling
system is defective. Other items which effect the refrigerator
operation may be the cause of the problem.
If you notice a loss of cooling, do a check for a failure of either
the electric or propane gas controls as follows:
- Change the energy source of the refrigerator.
- If the refrigerator is operating on propane gas, change it
to electric operation.
- If the refrigerator is operating on electric, change it to
propane gas operation.
- Operate the refrigerator for several hours.
- Make sure the refrigerator is level within 3° side-to-side
and 6° front-to-back.
- Make sure the controls are in the correct position for the
energy source in use.
- Make sure the gas pressure is 11 inches Water Column
(10.5 in. W.C. min. - 11.5 in W.C. max.) and the voltage
is 120 volts AC (108 v. min. - 132 v. max.) (on model
323 only 12 volts DC, 11.5 volts min. - 15.4 volts max.)
- Make sure the air flow in the lower intake vent, through
the refrigerator cooling system, and out through the
upper exhaust vent is not blocked or decreased.
- If no cooling is occurs after about eight hours, contact your
dealer or a Norcold authorized service center.
