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 appliances 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 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 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.
