The external gas connection (Fig. 102) is located at the rear or to the left or
right of the vehicle depending on the model.
Connect the external gas device to the connection point (Fig. 102,1).
Open the gas isolator tap (Fig. 102,2).
8.7 Duomatic switching facility
The Duomatic is an automatic switching facility with a remote display for a two-
bottle gas system. The Duomatic switching facility automatically switches gas
supply from the primary bottle to the reserve bottle as soon as the primary
bottle is either empty or no longer ready for operation. The gas appliances may
still continue operation. The Duomatic switching facility is suitable for all com-
mercial gas bottles from 3 kg to 33 kg.
Once you have made the connection and opened the gas isolator tap,
make sure that no gas is escaping at the connection point. If there is a
leak in the external gas connection, gas will escape into the open air.
Immediately close the gas isolator tap and the regulator tap on the gas
bottle. Have the external gas connection checked by an authorised spe-
cialist workshop.
When connecting an external gas appliance, make sure that there is
nothing near the external gas connection that could cause a spark.
Do not use the external gas connection to fill gas bottles. Observe the
information stickers on the external gas connection.

If the vehicle is equipped with a panel of the DT series and the switching
facility is operated via this panel, the operating unit is redundant.

tion manual.
