4. Liquid gas
The selected energy is displayed by the
correspondingLED(i.e.230V).
230V - operation
If sufficient supply voltage is available (more
than200V),thispowersourceisselectedasthe
first option ( no solar-system installed).
12V - operation
12Voperationshouldonlybeselectedwhilethe
vehicle motor is running or there is sufficient
voltage available from the sola system. This
canbedetectedfromtheD+connectionof
the alternator to the electronics, or from the

•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.
