When the vehicle’s engine is running, AES
selects 12V operation and LEDs (
A
) and (
D
)
are illuminated unless LP gas only opera-
tion 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.
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 selector button (
3
) is used to set the elec-
tronic 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 avail-
able)
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 cylin-
ders etc., the gas pipes may contain some air that should
be allowed to escape by briefly turning on the refrigerator
or other appliances. 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:
1. Turn off the refrigerator. (Press the ON/OFF
(
1
) to “OFF”.)
2. Check that there is enough gas in the gas bot-
tle, that its valve is open and that any valves in
the gas line to the refrigerator are open.
3. Turn on the refrigerator again. (Press the ON/
OFF button (
1
) to “ON” .) After 10 seconds
AES will repeat the ignition sequence.
4. Should the warning lamp come on again af-
ter approximately 6 minutes, the failure is still
present. Repeat the procedure once more. If
this does not help, contact an authorized ser-
vice provider in your area.

AES
The refrigerator is equipped with an Automatic Energy Se-
lector (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 or-
der:
1. 230-240V
2. 12V
3. LP gas
Turn off the AES function if you want the refrigerator to run
on LP gas only.
STARTING THE REFRIGERATOR
1. Press the ON/OFF button (
1
). The refrigera-
tor starts in the mode it was in when it was
turned off.
2. Press the AES/GAS button (
2
) and LED (
A
)
or (
B
) comes on. Select AES or LP gas only
by pressing the AES/GAS button (
2
) once if
necessary.
3. If a 230V-240V mains supply is available:
•
AES selects this as the energy source and
LEDs (
A
) and (
C
) come on.
While mobile:
• Do not operate the refrigerator on LP gas.
•
Turn off the gas bottle.
