3. Combined working pressure gauge (see drawing)
Built-in working pressure gauge to monitor and control the static working pressure
(overriding pressure p ), mounted with male nut G ½ B to the minus pressure chamber.

4. Pressure equalising valve (see drawing)
Allows zero control during the working process (with open valve)
T While the media are flowing from the side subject to higher pressure to the opposite
side, the differential pressure at the pressure gauge drops to zero (the differential
pressure readout must be at zero, i.e. fall into the area of the zero tolerance range which
shows that the gauge is working correctly).
T A zero adjustment can be made using standard integrated
adjustable pointer (previously remove snap fit bezel incl.
window and sealing ring). Twisting the pan head slotted screw
at the adjustable pointer you can adjust the zero point.
After completion of zero adjustment, the snap fit bezel
incl. window and sealing ring must be correctly re-mounted
and the pressure equalising valve must be closed again.

Mounting of mounting bracket
1. Bolt bracket to the wall by 2-4 bolts (depending
on mounting situation) using the mounting holes (A).
The fastening material is not part of the scope of delivery.
2. Bolt pressure gauge to fastening threads (B) or
(C) by means of the enclosed stud bolts and nuts.
