Owner’s Manual 6
Temperature control system:
Although the refrigerator is not frost -free, it is made to limit frost
on the cooling fins. At regular intervals, the temperature control
system automatically melts most of the frost from the cooling
fins. The water from the cooling fins drains into a collection cup
that is attached to the back of the refrigerator. The heat of the
cooling system evaporates the water from the collection cup.
Backup operating system:
This refrigerator has a backup operating system. The backup
operating system allows the refigerator to continue to cool if the
temperature sensor of the refrigerator should fail.
If this failure occurs:
- The refrigerator automatically changes to the backup
operating system.
- The ON light flashes a fault code. See the “Fault
Codes” section of this manual.
- The backup operating system can overfreeze or thaw
the contents of the freezer and the fresh food compart-
ment.
- Make sure the temperatures of the freezer and the fresh
food compartment are satisfactory.
NOTE: If you open the door(s) too often, the tempera-
tures inside the freezer and fresh food compart-
ment do not become stable. Allow the refrigera-
tor to operate for about one hour after each
adjustment change before you examine the
contents. The number “5” is the coldest
temperature setting.
- If the temperature is too warm, push the tempera-
ture switch to the right to raise the temperature
setting by one number.
- If the temperature is too cold, push the tempera-
ture switch to the left to lower the temperature
setting by one number.
- Have the refrigerator serviced by your dealer or an Norcold
authorized Service Center as soon as possible.
Operating the Refrigerator Controls
Control panel:
The refrigerator control panel (see Art01560) is between the
freezer compartment and the fresh food compartment. A 12 volt
DC power supply is necessary for the control functions of the
refrigerator to operate. The refrigerator receives DC power from
the 12 volt system of the vehicle; either an auxiliary battery, a
converter, or the vehicle engine battery.
The selector switch [1] starts and shuts down the refrigerator:
- Push the selector switch to the AUTO position to start the
refrigerator in auto mode.
- Push the selector switch to the GAS position to start the
refrigerator on propane gas.
The temperature switch [2] controls the temperature adjustment
of the freezer and the fresh food compartment. The temperature
adjustment that you select does not change if the mode of
operation of the refrigerator changes.
- Push the temperature switch to the desired temperature
setting.
- The number “5” is the coldest temperature setting.
Refer to the “Display Codes” section of this manual.
Automatic mode operation:
When the refrigerator is in AUTO mode, it automatically uses the
most efficient energy source that is available for operation.
During operation, if a more efficient energy source becomes
available, the refrigerator controls change from the current
energy source to the more efficient energy source as follows:
- The first choice is AC operation if 120 volts AC is available to
the refrigerator.
- The second choice is propane gas operation if 120 volts AC
is not available to the refrigerator.
Removing air from the propane gas supply lines:
For safety reasons, the burner is made to ignite on propane gas
within a specified amount of time. When starting the refrigerator
for the first time, after storage, or after replacing propane gas
tank, the propane gas supply lines can have air in them. Due to
the air in the gas supply lines, the refrigerator may not ignite on
propane gas within the specified amount of time.
To remove the air from the propane gas supply lines:
- Make sure that all of the gas valves are open.
- Push the selector switch to the GAS position and the
refrigerator will start a 30 second trial for ignition.
- During the 30 second trial for ignition, the refrigera-
tor controls open the gas safety valve and the
igniter sparks.
