The connection module allows you to connect
filters, water softening units, dosing devices and
physical water treatment units quickly. They can
be installed horizontally or vertically.

Insert the threaded joint and coupling ring with
the insert into the water pipeline and tighten the
screw connection.
Place the seals into the connection module and
secure the connection module between the
threaded joint and the insert.
See Fig. 3 for the positioning of the DR module
and the manometer.
1. Turn the locking ring to the left limit stop.
2. Press the prongs of the device into the
spaces provided and then rotate the device
45° clockwise to the limit stop.
3. Pull the locking ring with both hand towards
the device until it clicks into place. The
device cannot now be rotated
unintentionally.
To release the device, press the locking ring
together at both sides and push it towards the
connection module.

The back pressure can be changed by turning
the adjusting button (range 1.5 - 6 bar).
Turn the button clockwise to increase the back
pressure.
Turn the button anticlockwise to reduce the back
pressure.
The back pressure setting displayed (8

approximate value. The manometer (6

the exact pressure. A draw-off faucet downstream
of the pressure reducer must be opened and
closed briefly several times while setting the value.
The back pressure drops temporarily when water
is drained.
The back pressure may not exceed 80% of the
pick-up pressure of the hot water safety valve (DIN
1988).

return valve has closed properly, only a small
amount of water escapes, and there is no
