DESCRIPTION OF OPERATING MODES AUTO MODE

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 withAC 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.

GAS MODE

When operating in the GAS mode the AUTO mode in- dicator lamp (D) 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 igni- tion system and will make three attempt to light the burner for a period of approximately 45 seconds with two min- utes interval. If unsuccessful, the CHECK indicator lamp

(E)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 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, con- tact a service center for assistance.

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.

DC MODE

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 pressed to turn OFF the DC lamp (A).

IMPORTANT:

To prevent the refrigerator from being left on and draining the battery when the vehicle’s engine is not running and charging the battery.

It is recommended that an automatic cut-out relay be installed between the battery and the refrigerator toggle switch so that the refrigerator will not draw current when the ignition of the vehicle is switched off.

Alternatively, a suitable plug and receptacle should be installed in the 12 Volt supply line, so that the refrigerator can be disconnected from the supply, as necessary.

LIMP MODE OF OPERATION

This control system contains a feature where it will con- tinue to operate the cooling system in the event of a fail- ure of a major operating component. Two different modes of operation can occur in this category.

If for some reason the display module becomes non func- tional, the control system will revert to full automatic op- eration selecting the best energy source available with AC, DC and GAS priority. The temperature of the refrig- erator will be maintained at the MID position within nor- mal temperature tolerances. The power module will con- tinually 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 mode in- definitely or until a new sensor is installed and the sys- tem is reset.
