INSTALLATION OF THE BYPASS VALVE (ACCESSORY)

If a bypass valve is used between the built-in rotary flange and the dosing pump it will remain possible to
continue to draw a supply of untreated drinking water during possible maintenance of the dosing pump.
/
First flush the pipe with the newly installed built-in rotary flange. The built-in rotary flange is still sealed
by the black mounting cover.
/
Then shut-off the water again (at the stopcock or shut-off valve) and remove the mounting cover of the
built-in rotary flange.
/
Connect the bypass valve with the built-in rotary flange, by engaging the bayonet, on the flange side
with the cast-in letter "R" (R=Rohr [pipe]) (see fig. 6).

/
Tighten the four M6×25 hexagon socket head screws.
Select the tightening torque (about 4 Nm) so that the seal works effectively!
The hand wheel of the bypass valve can either project vertically upwards or to the side. Installation should
be performed so that, dependent on the local circumstances, the hand wheel can be easily accessed.
