Gas system

Operating modes The DuoControl switching facility has two operating modes:

z Winter operation "On and heating"

z Summer operation "On"

Putting into operation:

 Open the regulator taps on the gas bottles (Fig. 111,1 and 6).

 Use the knob (Fig. 111,4) on the reversing valve (Fig. 111,3) 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.

 Switch on the DuoControl switching facility at the operating unit (Fig. 112).

To do so, set the rocker switch (Fig. 112,7) to winter operation "On and

heating" (Fig. 112,2) or to summer operation "On" (Fig. 112,4). The

reversing valve is now deaerated. The yellow indicator lamp (Fig. 112,1)

illuminates if the winter operation has been selected and the regulator

defroster is activated.

Switching off:

 Set the rocker switch (Fig. 112,7) to " " (Fig. 112,3). The yellow indicator

lamp (Fig. 112,1) goes out.

 Close the regulator taps on the gas bottles (Fig. 111,1 and 6).

Remote display The indicator lamps on the operating unit (Fig. 112,5 and 6) indicate in the

vehicle interior whether the primary bottle is ready for operation.

Changing gas bottles If the green indicator lamp (Fig. 112,6) stops illuminating during operation and

the red indicator lamp (Fig. 112,5) illuminates, the gas bottle selected as pri-

mary bottle is empty and needs to be changed. The reserve bottle continues

supplying the gas appliances with gas.

Changing gas bottles:

 Close the regulator tap on the empty gas bottle.

 Unscrew the gas tube of the gas bottle.

 Connect the full gas bottle to the gas tube.

 Open the regulator tap on the gas bottle.

 Set the knob on the reversing valve with a half-turn, so that the newly

replaced gas bottle will serve as a reserve bottle.

7.8 Gas alarm system (special equipment)

The gas alarm system has two functions:

z Alarm in the case of an attack with narcotic gas

z Alarm if there is a leak in the gas system

X When changing gas bottles, do not smoke or create any open fire.

Z If the gas sensor or a cable is defective, the buzzer sounds until the defect

has been rectified.

Z If a deodorant spray, hairspray or a powerful cleaning agent is used in the

immediate vicinity of the gas sensor, a false alarm may be triggered.

Extended time in a tunnel (traffic jam) may also trigger a false alarm.

Z Also read the manufacturer's instruction manual.
