3-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 (4) 3-
WAY Model until the lamp at the desired setting is
illuminated.
D. AUTO MODE
1. Press the DC mode selector button (2) to the UP (OFF)
position.
2. Move the AUTO/GAS mode selector button (3) 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.
3. 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 3, under GAS
MODE).
4. Press the TEMPERATURE SELECTOR button (4) until
the lamp at the desired position is illuminated.
5. When operating in the AUTO mode, the AUTO modes
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 available, the system will automati-
cally switch to GAS. As soon as AC becomes available
again the control will switch back to AC regardless of the
GAS operation.
E. GAS MODE
1. Press the DC mode button (2) to the UP (OFF) position.
2. Move the AUTO/GAS mode selector button (3) to the UP
position. The GAS mode indicator lamp (C) will illumi-
nate. After 45 seconds the burner should be ignited and
operating normally.
3. 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 and then ON position.
If the control is switched to AC or DC 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.
4. Press the TEMPERATURE SELECTOR button (4) until
the lamp at the desired position is illuminated.
When operating in the DC mode, the DC mode indicator lamp
(A) will be illuminated. All other mode lamps will be off. The
DC mode overrides all other operating modes. If one of the
other operating modes is desired, the DC selector button (2)
must be in the UP (OFF) position.
G. BATTERY PROTECTION SYSTEM
The control system is equipped with a battery protection
system. A steady illuminated DC mode lamp (A) indicates
that sufficient voltage is present at the terminal block
connections to operate the refrigerator normally. If the input
voltage is below approximately 12.8 volts DC or should it
drop below 12.8 volts DC during operation, the DC mode
lamp (A) will flash ON and OFF to signal a low battery
condition. In this condition the control will continue to operate
in DC mode for a maximum of 10 minutes.
H. 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 initial start-up, the thermostat should be moved from
"COLDEST" to the desired temperature setting, usually
about mid-setting.
I. 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.
