Effects of High Altitude on Propane Gas
Operation
When you operate the refrigerator on propane gas at altitudes
higher than 5500 feet above sea level:
- You may experience reduced cooling performance of the
refrigerator.
- You may experience burner outages.
To avoid these possible problems, Norcold recommends that
you operate the refrigerator on AC when at altitudes higher than
5500 feet above sea level.
Refrigerator Care Checklist
Your refrigerator will give you years of trouble free service if you
do these simple checks every three to six months:
- Keep the food compartment and the freezer clean. See
“Cleaning”.
- Defrost the refrigerator as necessary. See “Defrosting”.
- Make sure the door seals correctly. See “Door Sealing“.
Do a test of the gas safety valve:
With an established flame in GAS mode:
1. Close the manual gas shutoff valve [2] of the refrigerator
(See Art01254].
2. After the flame is extinguished, you should hear a sharp
“click” sound within three minutes.
NOTE: The gas safety valve should close with a sharp “click“
sound.
3. Open the manual gas shutoff valve of the refrigerator.
4. Without pushing in the gas control, push the igniter several
times rapidly in succession. The burner flame should not
ignite. This means that the gas safety valve is working
correctly.
Start up - AC operation:
- Make sure that 120 volts AC is available.
- Turn the selector switch to the AC position (
).
- Turn the thermostat to the temperature setting that you
wish.
Start up - DC operation (3-way models only):
- Make sure that 12 volts DC is available.
- Turn the selector switch to the DC position (
).
DC operation precautions:
This refrigerator is made to operate on DC power while your
vehicle is “in transit” and AC power or propane gas sources
are not available. Operate the refrigerator on DC power only
when the vehicle engine is running.
For the refrigerator to operate correctly on DC power, the battery
must be maintained in a fully charged condition.
For the battery to be fully charged at all times during refrigerator
operation on DC, the vehicle engine
must be running and the
battery charging system must be in good operating condition.
Keep in mind the following electrical precautions for DC
operation of the refrigerator:
- Good battery condition is necessary for correct DC opera-
tion.
- The capacity of the battery charging system must be more
than what is necessary for the refrigerator and other DC
appliances.
- While the vehicle engine is running, have a qualified service
technician make sure the voltage of the DC power supply
leads at the refrigerator is more than 11.5 VDC.
DC operation guidelines:
DC operation is intended only to maintain the temperature of
the refrigerator and its contents when they are already cool.
The DC operation is not intended for the initial start up and
cooling of the refrigerator. Always use either the AC operation or
propane gas operation to initially start up and cool the refrigera-
tor. The refrigerator must be cooled and the temperature must
be steady before you operate the refrigerator on DC.
Keep in mind the following guidelines for DC operation of the
refrigerator:
- Use DC operation of the refrigerator while the vehicle is in
transit.
- Do not use DC operation until the refrigerator and its
contents are completely cooled.
- Only use DC operation if the vehicle battery and battery
charging system are in good operating condition.
Shut down:
- Turn the selector switch to the OFF position ( ).
