Installation

Personnel:
1. Mount the multifunction valve (Pos. 3) on the mounting bracket (Pos. 4) or similar
mounting plate by means of the enclosed plastic self-tapping screws. Fix the
mounting bracket to a wall.
2. Connecting the metering and return line.
3. Cut the hose (Pos. 5) evenly.
4. Place the union nut (Pos. 6) and the thrust piece (Pos. 7) over the hose up to the
stop collar on the connection nipple (Pos. 8).
5. Place the o-ring (Pos. 9) in the o-ring-nut and tighten the union nut (Pos. 6).
CAUTION!
The return line (venting line) must always be connected. The multiple
function valve is not an absolute sealing shut-off device. The minimal cross
section must correspond to the valve size (
on page 30).
In the case of dosing media which tend to crystallize, the overpressure
function cannot be guaranteed under certain circumstances.
