Gas system

Construction of the unit The DuoControl regulating system consists of a reversing valve (Fig. 35,4)
and a crash sensor (Fig. 35,5). The DuoControl regulating system is installed
between the gas tubes (Fig. 35,3) with hose break guard (Fig. 35,1). The knob
(Fig. 36,1) on the reversing valve is used to select which of the gas bottles is
to be used as primary bottle and which is to be used as reserve bottle.
The status of the gas supply is indicated in the inspection window (Fig. 36,2):
z
Green: Gas is taken out of the primary bottle.
z
Red: Gas is taken out of the reserve bottle.
The operation with only one gas bottle is allowed but in this case the open con-
nection must be closed with a blind cover (Fig. 36,4).
Crash sensor The crash sensor blocks the gas supply in the event of a significant impact
(e.g. accident). The crash sensor is put into operation with the green reset
button (Fig. 36,3).
Hose break guard The hose break guard (Fig. 35,1) blocks the gas flow if the connected hose
breaks. The hose break guard must be activated by pressing the green button.
Defroster The DuoControl regulating system can be heated (defroster). If winter opera-
tion is set at the operating unit, the DuoControl regulating system will be
heated automatically. Thus, faults of the gas system due to frost in winter are
prevented.
Operating unit At the operating unit (Fig. 37), the gas supply via the DuoControl regulating
system is switched on and off. The regulator taps (Fig. 35,2) of the gas bottles
and the gas isolator taps of the devices must be opened manually.
Summer and winter operation are switched with the rocker switch (Fig. 37,7)
of the operating unit.
