LP gas-only operation can be selected by pressing the AES/
GAS button (2) until LED (B) comes on; the AES function is
then turned off and LED (A) goes out. The Temperature selec-
tor button (3) is used to set the electronic thermostat. The LEDs
(E) show the value set on the thermostat.
LP GAS OPERATION
AES will select LP gas operation under the following
conditions:
No AC (230-240V) available•
Engine not running (no high current at 12V DC available)•
When the system chooses LP gas operation, the flame failure
device is automatically opened, allowing the gas to flow to the
burner. At the same time, the electronic igniter is energized.
After initial installation, servicing, or changing gas cylinders
etc., the gas pipes may contain some air that should be allowed
to escape by briefly turning on the refrigerator or other appli-
ances. This will ensure that the flame lights immediately.
If the flame goes out (by gust of wind etc.), the reigniter will
automatically relight the flame.
The control electronics and the igniter must have
12V DC (battery) supply to operate!
GAS TROUBLESHOOTING
If the Warning indicator lamp (F) is lit, there has been a failure
of gas operation.
To troubleshoot, follow these steps:
Turn off the refrigerator. (Press the ON/OFF (1. 1)
to “OFF”.)
Check that there is enough gas in the gas bottle, 2.
that its valve is open and that any valves in the gas
line to the refrigerator are open.
Turn on the refrigerator again. (Press the ON/3.
OFF button (1) to “ON” .) After 10 sec. AES will
repeat the ignition sequence.
Should the warning lamp come on again after ap-4.
prox. 6 minutes, the failure is still present. Repeat
the procedure once more. If this does not help,
contact an authorised service provider in your
area.
ABNORMAL OPERATION
Any of the following are considered to be abnormal operation
and may require servicing:
Yellow tipping of the burner flame.•
Sooting up area surrounding burner.•
Burner not igniting properly.•
Burner failing to remain alight.•
In case the appliance fails to operate correctly, contact an au-
thorised Dometic Service Centre.
230-240V OPERATION
When a mains connection is available, AES will select this.
Please note, that even being in AC mode, 12V DC is necessary
for the internal supply of the electronics.
OPERATING INSTRUCTIONS
CONTROL PANEL
AES
The refrigerator is equipped with an Automatic Energy
Selector (AES) controlling the operation and energy supply.
NOTE! 12V must always be available to supply the
electronics.
The system selects the available energy source in the order:
230-240V1.
12V 2.
LP gas3.
Turn off the AES function if you want the refrigerator to run
on LP gas only.
STARTING THE REFRIGERATOR
Press the ON/OFF button (1. 1). The refrigerator
starts in the mode it was in when it was turned off.
Press the AES/GAS button (2. 2) and LED (A) or (B)
comes on. Select AES or LP gas only by pressing
the AES/GAS button (2) once if necessary.
If a 230V-240V mains supply is available:3.
AES selects this as the energy source and LEDs •
(A) and (C) come on.
When the vehicle’s engine is running, AES •
selects 12V operation and LEDs (A) and (D) are
illuminated unless LP gas only operation has
been selected manually.
If neither mains nor a 12V battery supply are
available:
AES selects LP gas operation and LEDs (• A) and
(B) come on.
