the TEMP SET button.

The MODE button [8] controls the operation mode of the
refrigerator.
- Push and hold the MODE button and a light bar shows in
the center display beside each of the operating modes of
the refrigerator, one at a time.
- There is one automatic mode of operation and two
manual modes of operation.
- When the light bar shows beside the mode of opera-
tion that you choose, release the MODE button to
operate the refrigerator in that mode.
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 burner 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 ON / OFF button to turn the refrigerator on.
- Push and hold the MODE button until the light bar beside
LP GAS shows.
- This means that the refrigerator is operating on
propane gas.
- If the air in the propane gas supply lines prevents the
burner from ignition on propane gas, the fault code “F”
will appear in the center display.
- Push the MODE button 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.
- After 30 seconds, the refrigerator controls closes
the gas safety valve and the igniter stops sparking.
- When the light bar beside the LP GAS [6] shows and no
fault code remains, this means that the refrigerator is
operating on propane gas.
- At this time, all of the air is removed from the propane
gas supply lines and you may select AUTO mode of
operation if you wish.
- Depending on how much air may be in the propane gas
supply lines, you may need to repeat the 30 second trial for
ignition two or three times.
- If the burner does not ignite on propane gas after two or
three attempts, stop and consult your local dealer or an
authorized Norcold Service Center.
Set the controls to automatic mode operation:
- Push the ON / OFF button to turn the refrigerator on.
- Push and hold the MODE button until the light bar shows
beside AUTO [3] and then release.
- If 120 volts AC is available to the refrigerator:
- The light bar beside AC [4] also shows in the center
display.
- After ten seconds, the light bar beside AC goes off and
only the light bar beside AUTO remains.
- This means that the refrigerator is operating on AC
electric.
- If 120 volts AC is not available to the refrigerator:
- The light bar beside AC [4] also shows in the center
display.
