✱
Screw the ammonia sensor into the fitting and tighten to 3 Nm.
✱
The process medium that escapes from the overflow (4) can be
drained through a tube.
✱
Turning the handwheel (3) left/counter-clockwise (A) opens the
fitting, turning to the right/clockwise (B) closes the fitting.
Attention:
The installation position of the fitting is vertical (as
shown in the drawing)!
The sensor may only be removed when the fitting is
closed!
Do not close the discharge (4)!
Optimum operating pressure: 2 to 3 bar.
Maximum operating pressure: 6 bar.
Note
If too much process medium runs out of the overflow:
- Reduce the system pressure
- Mount the quick-change fitting in the bypass with a
control valve upstream
If not enough process medium runs out of the
overflow, the ammonia sensor may respond too late
or not at all to an ammonia leak. In this case, the flow
rate must be increased:
- Install the PTFE washer with higher porosity (part
no. 00583479, black, for higher flow rate).
