STARTING THE REFRIGERATOR
Whilst mobile:
Do not operate the refrigerator on LP gas. •
Turn off the gas bottle. •
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.
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!

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.
