During change-over between the different energy sources, intended delays
are installed in the version with automatic power selection. This means, that
after a change-over to a new energy source the refrigerator can not be oper-
ated immediately. When changing from 12 Volt operation to gas operation,
the delay is 15 minutes. This prevents a change-over to gas operation when
the vehicle is stopped briefly (e.g. stop to fill tank).
 Open flames are prohibited at petrol stations.
If the refrigerator was manually set for gas operation during the jour-
ney: switch off the refrigerator in the petrol station area or change over
to 12 V operation.
If the refrigerator was operated in the automatic mode during the jour-
ney (only in the case of the version with automatic power selection)
and the stop for filling the tank takes longer than 15 minutes: switch
off the refrigerator. Otherwise, the automatic power selection system
will automatically change over to gas operation 15 minutes after stop-
ping the vehicle engine.
When selecting gas operation the ignition fuse is opened automatically so
gas can get into the burner. At the same time the electronic ignition is acti-
vated. If the gas flame is extinguished, e.g. by blast of wind, the ignition is
activated immediately and re-ignites the gas.
