7.7 DuoControl switching facility (special equipment)

The DuoControl is an automatic switching facility with a remote display for a

two-bottle gas system. The DuoControl 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 DuoControl switching facility is

suitable for all commercial gas bottles from 3 kg to 33 kg.

Construction of the unit The DuoControl switching facility consists of a reversing valve (Fig. 111,3) and

an operating unit (Fig. 112). The reversing valve is installed between the gas

tubes (Fig. 111,2 and 5). The knob (Fig. 111,4) on the reversing valve is used

to select which of the gas bottles is to be used as a primary bottle and which

is to be used as a reserve bottle.

The reversing valve is equipped with the regulator defroster Eis-Ex. This pre-

vents damage to the gas system during the winter months.

Only the electrical functions can be switched at the operating unit (Fig. 112).

The regulator taps on the gas bottles (Fig. 111,1 and 6) must be opened man-

ually.

The reversing valve provides a constant gas pressure, regardless of which gas

bottle is being drawn upon. The two indicator lamps on the operating unit indi-

cate the level of the primary bottle. When the green indicator lamp (Fig. 112,6)

illuminates, the primary bottle is full. When the red indicator lamp (Fig. 112,5)

illuminates, the primary bottle is empty. In this case, the reserve bottle is used

for the gas supply.

X Do not use the switching facility in closed spaces.

Z Also read the manufacturer's instruction manual.
