in the LCD display.
■ Number one (1) is the warmest temperature setting.
■ Number nine (9) is the coldest temperature setting.
Touch and hold the Temperature Set button to scroll through tem-
perature settings, one after the other. Release the Temperature Set
button when the desired temperature setting appears.
Or touch and release the Temperature Set button to change the

Gas Operation
When either AUTO or MANUAL GAS mode is selected, the refrig-
erator attempts to ignite the propane gas burner. If unable to ignite
the burner and to maintain a fl ame, the fault code "no" "FL" appears
in the LCD display.
Gas Mode
In AUTO GAS mode and MANUAL GAS mode, the controls ener-
gize the solenoid coil to open the gas valve. Spring pressure closes
the valve when the controls stop the fl ow of current to the solenoid
coil.
■ The propane gas burner will cycle in response to the fin tem-
perature to maintain cabinet temperature.
■ The controls use an electronic sparker to ignite the propane gas
at the burner.

AC Mode
AUTO AC or MANUAL AC mode operation requires 108 to 132
volts AC. Voltage is to be supplied through a 2 pole, 3-wire, 20 Amp
grounding type receptacle.
A 120 volt AC heater generates the heat load required for AUTO
AC and Manual AC operation. To replace the heater, the refrigera-
tor must be removed from the enclosure.
WARNING
!
ATTENTION
The AC electric heater will cycle in response to the fi n temperature
to maintain the cabinet temperature.
Air in the Propane Gas Supply Lines
NOTICE
Diagnostic Pre-Checks
Diagnosing fault codes begins by starting with the basics. In many
cases, the problem can be solved by verifying that the refrigerator
is operating in acceptable conditions. Make sure that:
■ The refrigerator is plugged into a known working AC outlet
with a voltage between 108 VAC and 132 VAC.
■ Extension cords are not being used to supply AC power to
the refrigerator.
■ The refrigerator is connected to a known working DC
power supply and/or battery supplying between 10.5 and
16.0 VDC
■ Propane gas is available to the refrigerator and is regulated
between 10.5 and 11.5" WC (Inches of Water Column).

Burn hazard! Allow canister and heaters
to cool before attempting to remove and
replace.
For safety reasons, the refrigerator elec-
tronic controls are designed so that while
operating in Propane Gas Mode, the trial
for ignition (the maximum time that the
gas valve and the igniter can be left on
without a fl ame present) is limited to 30
seconds. When starting the refrigerator
for the fi rst time, after storage, or after
replacing the propane gas tanks(s), the
propane gas supply lines can have air in
them.
Due to the air in the gas supply lines, the
burner may not ignite within the 30 second
time limit. If this happens, the gas valve
and igniter outputs will be turned off, the
propane gas mode will be "locked out",
and the appropriate fault code will show in
the display.
The gas lock out condition can be reset
by powering the refrigerator OFF and
back ON, at which time a new 30 second
trial for ignition will begin. You may need
to repeat this procedure several times to
remove all of the air from the gas supply
lines.
