Refrigerator Start-Up Information

The new Dometic Refrigerator has been designed to provide more cooling power than ever before surpassing all agency requirements and customer expectations. When starting this refrigerator for the very first time, the cooling cycle may require up to four hours of running time before the cooling unit is fully operational.

MODELS INCLUDE:

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 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.

GAS MODE

When operating in the GAS mode, the AUTO mode indicator lamp (D) will not 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 (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 45 second 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 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

(3-Way

Models Only)

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.

SPECIAL FEATURES 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 the display module becomes nonfunctional, the control system will revert to full automatic operation

(3-way

selecting the best energy source available with AC, DC

only) 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 Special Feature 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.

NOTE: The operational range of these refrigerators is 46

AES REFRIGERATOR OPERATION

Models Include: RM3607 and RM3607

AES MODE

3-WAY AES DISPLAY PANEL

The AES mode of operation takes priority over all other operating modes. If more than one mode selector

(2),

button

(3) or (4) is in the down position, the priority is from left to right.

When operating in the AES mode, the AES mode indicator lamp (A) will illuminate. In this mode the control system will automatically select the energy source with AC having top priority, DC second priority and GAS third priority. If the control system has selected a particular energy source such as AC, and then it becomes unavailable, it will automatically seek out the next available energy source.

AC/GAS MODE

When operating in the AC/GAS mode the AC/GAS mode indicator lamp (B) will illuminate. In this mode of operation the control system will automatically select between the AC and GAS energy sources with AC

having first priority.

GAS MODE

When operating in the GAS mode, the mode indicator lamp (E) will illuminate. The GAS 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 (G) 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 control is switched to the AES or AC/GAS mode of operation while the CHECK indicator lamp is on,

it will function properly on AC or DC, but if the CHECK indicator lamp is on, it will not go off until the main

power ON/OFF button is pressed to the OFF then ON position.

BATTERY

PROTECTION SYSTEM

The control system is equipped with a battery protection system. If AC power is not available, the control will switch to the DC energy source. If the input voltage at the terminal block connections is below 12.8 volts, the control system will bypass the DC energy source and attempt GAS operation, If the GAS

energy source is available, CHECK lamp is on, the control system will return to the DC energy source. The control will operate in the DC mode for a maximum of 10 minutes.

If the input voltage has not returned above 12.8 volts within this time, the control will terminate DC operation and turn off the DC lamp (F) and start gas operation if GAS energy source is available and check light is not on.

The input battery voltage must rise above 12.8 volts for 25 minutes before DC operation can resume. As soon as the input voltage rises above the required 12.8 volts, the DC mode lamp (F) will illuminate;

however, the control system will remain in the 25 minute delay mode and operate on gas. This delay is

to allow sufficient time for the vehicle charging system to recharge the battery. If 120 volt AC becomes

available during the 25 minute delay, the control will automatically switch energy source.

SPECIAL FEATURES 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 the display module becomes nonfunctional, the control system will revert to full automatic operation

selecting the best energy source available with AC, DC 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 Special Feature 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 and could freeze. The refrigerator will continue to operate in this mode indefinitely or until a new sensor is installed and the system is reset.

NOTE: The operational range of these refrigerators is 46°F to 35°F
