3. OPERATING INSTRUCTIONS
2-WAY MODEL
A. A 12 volt DC supply must be available for the electronic
control to function.
B. Press the main power ON/OFF button (1) to the DOWN
position.
C. Press the TEMPERATURE SELECTOR BUTTON (3) 2-
WAY Model until the lamp at the desired setting is
illuminated.

D. AUTO MODE
1. Move the AUTO/GAS mode selector button (2) to the
DOWN position. (If 120 volts AC is available, the AC
mode indicator lamp (B) will illuminate indicating AC
operation. If 120 volts AC is not available, the GAS mode
indicator lamp (C) will illuminate and the control system
will automatically switch to GAS operation.
2. If the CHECK indicator lamp (E) illuminates and the GAS
mode indicator lamp (C) is off, the controls have failed to
ignite the burner in the GAS mode. GAS operation may
be reset by pressing the main power ON/OFF button (1)
to the OFF then ON position. (See Step 2, under GAS
MODE).
3. Press the TEMPERATURE SELECTOR button (3) until
the lamp at the desired position is illuminated.
4. When operating in the AUTO mode, the AUTO mode
indicator lamp (D) will illuminate. The control system will
automatically select between AC and GAS operation
with AC having Priority over GAS. Either the AC indicator
lamp (B) or the GAS indicator lamp (C) will illuminate
depending on the energy source selected by the control
system. If the control system is operating with AC energy
and it then becomes unavailable, the system will auto-
matically switch to GAS. As soon as AC becomes
available again the control will switch back to AC regard-
less of the status of GAS operation.
E. GAS MODE
1. Move the AUTO/GAS mode selector button (2) to the UP
position. The GAS mode indicator lamp (C) will illumi-
nate. After 45 seconds the burner should be ignited and
operating normally.
2. On the initial refrigerator start-up, it may take longer than
45 seconds to allow air to be purged from the gas line. If
the gas does not ignite within 45 seconds the CHECK
indicator lamp (E) will illuminate and the GAS mode
indicator lamp (C) will go off. To reset when the CHECK
indicator lamp (E) is illuminated, press the main power
ON/OFF button (1) to the OFF then ON position.
If the control is switched to AC operation while the
CHECK indicator lamp is on, it will function properly, but
the CHECK indicator lamp will not go off until the main
power ON/OFF button is pressed to the OFF then ON
position.
NOTE: Do not continue to reset GAS operation if the
CHECK indicator lamp continues to be illuminated after
several tries. If repeated attempts fail to start the LP gas
operation, check to make sure that the LP gas supply
tanks are not empty and all manual shutoff valves in the
lines are open. If the problem is still not corrected,
contact a service center for assistance.
3. Press the TEMPERATURE SELECTOR button (3) until
the lamp at the desired position is illuminated.
F. THERMOSTAT
The thermostat on the refrigerator controls both the gas and
electric operation, thereby eliminating the necessity of
resetting each time a different energy source is employed.
After the initial start-up, the thermostat should be moved
from "COLDEST" to the desired temperature setting, usually
about mid-setting.
G. STANDBY MODE OF OPERATION
This control system contains a feature where it will continue
to operate the cooling system in the event of a failure of a
major operating component. Two different modes of opera-
tion can occur in this category.
If for some reason the display module becomes nonfunc-
tional, the control system will revert to fully automatic
operation - selecting the best energy source available with
AC and GAS priority. The temperature of the refrigerator will
be maintained at the MID position within normal temperature
tolerances. The power module will continually attempt to
reestablish operation of the display module.
The second standby mode of operation will execute when a
failure of the temperature sensing device or associated
electronic circuitry occurs. If this should occur, the control
system will operate on the energy source selected via the
control panel. The cooling unit will run continuously on the
selected energy source. The refrigerator will continue to
operate in this mode indefinitely or until a new sensor is
installed and the system is reset.
H. TO SHUT OFF THE REFRIGERATOR
The refrigerator may be shut off while in any mode of
operation by pressing the main power ON/OFF button to the
UP (OFF) position. This shuts off all DC power to the
refrigerator.
