Dometic Official Guidelines for RM 7655 L - Energy Operation Methods

230 V - operation

If sufficient supply voltage is available (more than 200V), this power source is selected as the first option ( no solar-system installed).

12 V - operation

12V operation should only be selected while the vehicle motor is running or there is sufficient voltage available from the solar system. This can be detected from the D+ connection of the alternator to the electronics, or from the respective sig- nal on the solar charge regulator.

Gas operation

Gas operation is selected in the following circumstances:

￿No supply voltage available.

￿The vehicle engine is not running.

￿Supply voltage less than 200V

REFUELLING STOP

In order to prevent unintended switching to gas operation during refuelling, the electronic system starts gas operation of the refrigerator, after the motor has been turned off for 15 mins. During this time the appliance is in stand-by operation mode and only the "AUTO" LED lights up.

The use of naked flames is prohibited in petrol station environments.

If the refuelling stop lasts longer than 15 mins., the refrigerator should be switched off at the main switch (A), or switched over to another energy type.

5.2.5Gas faults (RM 76x1 and RM 76x5)

A	C If gas faults occur the operating LED “C”
	flashes yellow.

Remedies:

Set the energy selector switch (A) to position “OFF”.

1.Is there any gas in the gas bottle?

2.Is the gas bottle valve open?

3.Is the on-board shut-off valve open?

4.Set the main switch (A) to “on” The ignition starts again.

If after about 30 seconds the operating display (C) starts flashing red again, the gas fault has not been cleared (e.g. air in the gas pipe).

5.Briefly switch the refrigerator off and then on again using main switch (A). To remove air from the gas pipes, repeat this procedure 3-4 times.

If these actions do not help, please call an authorised Dometic Service Centre.
