START UP INSTRUCTIONS
A. A continuous 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)
until the lamp at the desired setting is illuminated.
AES/AUTO MODE
1. Press the AES/AUTO/GAS mode selector button (2)
to turn ON the AES/AUTO lamp (B). If 120 volts is
available, the AC mode indicator lamp (A) will illumi-
nate indicating AC operation. If 120 volts AC is not
available, the GAS indicator lamp (C) will illuminate,
indicating the control has automatically switched to
the GAS mode.
2. If the CHECK indicator lamp (D) 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.
GAS MODE
1. Press the AES/AUTO/GAS mode selector button (2)
to turn OFF the AES/AUTO lamp (B). The GAS mode
indicator lamp (C) will illuminate. Within 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 (D) will illuminate and the
GAS mode indicator lamp (C) will go off.
To reset when the CHECK indicator lamp (D) is
illuminated, press the main power ON/OFF button (1)
to the OFF and then ON position.
NOTE: Do not continue to reset GAS operation if the
CHECK indicator lamp continues to be illuminated
after several tries.
3. Press the TEMPERATURE SELECTOR button (3)
until the lamp at the desired position is illuminated.
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 em-
ployed. After the initial start-up, the thermostat should
be moved from "COLDEST" to the desired temperature
setting, usually at mid setting.

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, including the interior light.
DESCRIPTION OF OPERATING
MODES
AES/AUTO MODE
When operating in the AES/AUTO mode, the AES/AUTO
mode indicator lamp (B) will illuminate. The control
system will automatically select between AC and GAS
operation with AC having priority over GAS. Either the
AC indicator lamp (A) 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 automatically switch to GAS. As soon a s A C be-
comes available again the control will switch back to AC
regardless of the status of GAS operation.
GAS MODE
When operating in the GAS mode the AES/AUTO mode
indicator lamp (B) will be off and the GAS mode indicator
lamp (C) will be illuminated.
This mode provides LP gas operation only. The control
system will activate the ignition system and will attempt
to light the burner for a period of approximately 45
seconds. If unsuccessful, the CHECK indicator lamp (D)
will illuminate and the GAS mode indicator lamp (C) will
turn off.
To restart GAS operation, press the main power
ON/OFF button (1) to the OFF and then ON position. The
control system will attempt a new 45 seconds ignition
sequence.
If the refrigerator has not been used for a long time or
the LP tanks have just been refilled, air may be trapped
in the supply lines. To purge the air from the lines may
require resetting the main power ON/OFF button (1)
three or four times. 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.
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.
