Gas Fittings
7.6 Duomatic Switching Facility (Special Equipment)
The Duomatic is an automatic switching facility with a remote display for a two-bottle gas system.
The Duomatic switching facility automatically switches gas feed from the primary bottle to the re-
serve 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 commercial
gas bottles from 3 kg to 33 kg.
Construction
The Duomatic switching facility consists of a central regulator (Fig. 86,3) and a switching regulator
(Fig. 86,5). The knob (Fig. 86,6) on the switching regulator 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. Both regulators are
equipped with a pressure controller and the regulator defroster Eis-Ex.
The manometer (Fig. 86,2) on the central regulator indicates the pressure in the gas bottle, not the
filling level of the gas bottle. The manometer can be used to test the impermeability of the gas bottle.
The control unit (Fig. 87) only controls the electrical functions. The regulator taps on the gas bottles
(Fig. 86,1 and 4) must be opened manually.
Operation
³
Open the regulator taps on the gas bottles (Fig. 86,1 and 4).
³
Use the knob (Fig. 86,6) on the switching regulator (Fig. 86,5) 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.
When the knob is in the red area, the gas is taken primarily from the gas bottle with the central
regulator (Fig. 86,3).
When the knob is in the green area, the gas is taken primarily from the gas bottle with the
switching regulator (Fig. 86,5).
³
Select the operating mode on the remote display (Fig. 87) and switch on the Duomatic switching
facility. Both gas pressure regulators are now ventilated.
The central regulator provides a constant gas
pressure, regardless of which gas bottle is be-
ing drawn upon. The two indicator lamps on the
remote display show which gas bottle can be
used to provide gas. When both indicator lamps
are illuminated, the position of the knob on the
switching regulator indicates which gas bottle is
currently being drawn upon.

When operating with only one gas
bottle (e. g. during the summer)
connect the central regulator to
this bottle. Position the knob on
the switching regulator in the red
area.
