230 V operation If the 230 V power supply is connected, this energy source is selected as the first pri-
ority by the AES.
12 V operation 12 V operation is only selected by the AES if the towing vehicle's engine is running
and the alternator supplies sufficient 12 V operating power.
Gas operation
If the 230 V power supply is disconnected and the towing vehicle's engine is not
running the AES selects the gas supply. When selecting gas operation the ignition
fuse is opened automatically so that gas can flow into the burner. At the same time
the electronic ignition is activated. If the gas flame is extinguished, e.g. by blast of
wind, the ignition is activated immediately and re-ignites the gas. When the gas
operation is faulty, the "GAS" indicator lamp (Fig. 137,2) flashes red.
Change-over between
energy sources
When changing over between the different energy sources there are forced delays
built in the AES. This means, that after a change-over to a new energy source the
refrigerator can not be operated immediately. When changing over from 12 V ope-
ration to gas operation, a 15 minute delay is built in the AES.
This prevents a change-over to gas operation when the vehicle is stopped briefly
and the engine is switched off (e.g. stop to fill tank).
Z Even when the 12 V supply is switched off, a small electrical current flows which
puts an extra load on the living area battery. Always switch the refrigerator off
during a temporary lay-up.

X Never let gas escape unburned due to danger of explosion.
X Gas operation of the refrigerator with liquefied petroleum gas is not permis-
sible.
Z Open the regulator tap on the gas bottle and the gas isolator tap "Refrigerator".
X Open flames are prohibited at petrol stations. If the stay lasts longer than
15 minutes, the refrigerator must be switched off at the energy selector
switch.
