Installation and Owner’s Guide 6
Do a test of the gas safety valve:
With an established flame in GAS mode:
1. Close the manual gas shutoff valve [3] of the refrigerator
(See Art00952].
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 and the AC fuse [4]
is working correctly.
- Turn the energy selector to the AC position.
- Turn the gas control to the OFF position.
Start up - DC operation (model 323 only):
- Make sure that 12 volts DC is available and the DC fuse
[5] is working correctly.
- Turn the energy selector to the DC position.
- Turn the gas control to the OFF position.
The refrigerator receives its DC power from the 12 volt system
of the vehicle; either the vehicle engine battery or an auxilliary
(house) battery. The 12 volt system of the vehicle supplies DC
power only to the refrigerator but also to any other DC appli-
ances of the vehicle. When operating on DC, the refrigerator
has a high current draw and can cause a rapid battery
discharge.
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 refrigera-
tor 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 opera-
tion 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 gas control to the OFF positon.
- Turn the energy selector to the GAS position.
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.
