Installation and initial start-up
During installation (see Fig. 4), the correct operating
position must be observed.
For side mounting, observe the "Top" arrow on the
type plate.
The float must be able to move freely over the
whole range of movement and must not be restric-
ted by the tank walls or by fittings in the tank.
Applications where turbulence is present (e.g. stirring apparatus) can interfere with the function and should,
in all cases, be avoided.
Process connection flange - industrial series
For switches of the industrial series with flanges according to DIN, ANSI, etc., the gaskets1) and connecting
stud bolts1) used must correspond to the industry standard as regards material, pressure class and type of
gasket and must be tightened to the corresponding tightening torques.

Connecting
1. Remove protective plugs from the valve body
2. Assemble the hose or pipe screwed connection according to the control function and check that it
is correctly seated.
If operation appears faulty, clean the aperture in the connection port "p" with needle.
3. Carefully allow the control pressure (supply air) to build up.
CAUTION: use only clean control air; if necessary, install a filter!

Fault finding (Fault correction / rectification)
•
Is the housing leak-proof - bolts well tightened?
•
In the case of type series MV.../FMV... - is the vent valve leak-proof?
•
Remove the jet and clean connection port "p" with needle or compressed air!
•
Remove any dirt particles which may be present in the threaded bore of the jet!
•
Use only clean compressed air; if necessary install a filter!
•
Check the compressed air!
Never adjust nuts / regulating screws for the jet needle in the interior of the housing!
•
Connection port "E" must always be open / vented! It is absolutely normal that escaping air creates
a noise. This is not a malfunction.
