Installation of the device
CAUTION
The pipe must be able to safely
support the device (weight: see
chapter 8). If necessary, the pipes
must be provided with additional
fastenings or support.
If no bypass valve is installed, a
shut-off valve must be installed
upstream of the unit in order to
interrupt the water supply during
installation, maintenance, repair or
malfunction of the device.
Install the device in a vertical posi-
tion (± 5°). Otherwise, water may
escape and cause water damage.
For the installation of the device
in domestic water piping, only use
the supplied built-in rotary flange
(see chapter 3.2).
The flange surface of the rotary
flange fitting must be upright!
For proper sealing the profile of
the profile flange seal must point
towards the rotary flange fitting
(see
).
1.
Screw the rotary flange fitting back
onto the device using the four hexagon
socket head screws.
UNIT

2.
Position the device with the fitted rotary
flange fitting between the grommets and
insert the flat gaskets on both sides.
3.
Screw the device with the union nuts on
both sides.
4.
