The DuoControl regulating system can be heated (defroster). If winter oper-
ation 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.

Fig. 124 Operating unit (DuoControl)
At the operating unit (Fig. 124), the gas supply via the DuoControl regulating
system is switched on and off. The regulator taps (Fig. 122,2) of the gas bot-
tles and the gas isolator taps of the devices must be opened manually.
Summer and winter operation are switched with the rocker switch
(Fig. 124,7) on the operating unit.
The two indicator lamps on the operating unit indicate the level of the pri-
mary bottle. When the green indicator lamp (Fig. 124,6) is lit, the primary
bottle is sufficiently filled. When the red indicator lamp (Fig. 124,5) illumi-
nates, the primary bottle is empty. In this case, the reserve bottle is used for
the gas supply.

Connect the gas bottles.

Use the knob (Fig. 123,1) on the reversing valve to select the gas bottle
which is to be the primary source of gas (primary bottle). Always turn the
knob as far as it will go.

Open regulator taps (Fig. 122,2) on the gas bottles.

Press the green button of the hose break guard (Fig. 122,1). The green
marking is shown in the inspection window (Fig. 123,2).

Switch on the DuoControl regulating system at the operating unit
(Fig. 124). To do so, set the rocker switch (Fig. 124,7) to winter opera-
tion (Fig. 124,2) or to summer operation (Fig. 124,4). The yellow de-
froster indicator lamp (Fig. 124,1) is lit when winter operation is selected.

Set the rocker switch (Fig. 124,7) to the OFF position (Fig. 124,3). The
indicator lamps go out.

Close regulator taps (Fig. 122,2) on the gas bottles.
 When changing gas bottles, do not smoke or create any open fire.
 When you have changed the gas bottle, check whether gas escapes
at the connection points and unions. Use a leakage search spray to
spray the relevant connection point or union. These agents are
available at the accessories shop.
