4-14.14.7 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 as AC
becomes available again the control will switch back to AC regardless of the status of GAS operation. Refer to Display Panel
found previously for illustration.
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 make
three attempts to light the burner for a period of approximately 45 seconds with two minute intervals. 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 ignition sequence.
If the refrigerator has not been used for a long time or the LP tanks have just been refi lled, 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.
LIMP 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 operation can occur in this category.
If for some reason the display module becomes non functional, the control system will revert to full automatic operation
selecting the best energy source available with AC, 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 limp 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 module
indefi nitely or until a new sensor is installed and the system is reset.
4-14.14.8 How to Use the Refrigerator
FOOD STORAGE COMPARTMENT
The food storage compartment is completely closed and unventilated, which is necessary to maintain the required low
temperature for food storage. Consequently, foods having a strong odor or those that absorb odors easily should be covered.
Vegetables, salads etc. should be covered to retain their crispness. The coldest positions in the refrigerator are under the
cooling fi ns and at the bottom of the refrigerator. The warmer areas are on the upper door shelves. This should be considered
when placing different types of food in the refrigerator.
When the refrigerator is heavily loaded, it will take a longer time to lower the temperature; therefore, to get maximum
effi ciency the refrigerator and food items should be pre-cooled prior to loading. The shelves should not be covered with paper
or plastic, and the food items should be arranged so air can circulate freely.
If you need more space in the refrigerator you can lift up the front of the second shelf from the top and push the shelf in, the
shelf will fall down against the fi nned evaporator. This shelf cannot be relocated to a different position within the refrigerator.
The middle shelf is a sliding shelf, to slide out grasp the front of the shelf and pull forward. Push the shelf in to return to
original position. This shelf cannot be relocated to a different position within the refrigerator.
The lower door shelf is designed for large containers or bottles (1/2-gallon milk or juice).
