Installation flow sensor (FS)
M ount ball valves up- and down-
■
stream of the flow sensor.
Consider the correct installa-
■
tion point. Normally this is the
outlet pipe (colder pipe for heating,
warmer pipe for cooling). Please
note the type plate information (see
also page 19).
C onsider the correct flow direction.
■
This is indicated by an arrow on the
side of the flow sensor.
T he flow sensor can be installed in
■
any position (also „overhead").
Do not install at highest point of
■
piping to avoid air inside the flow
sensor.
Consider the dimensions of the
■
meter.

Installation of the temperature sensors
The installation of the temperature
■
sensors should be preferably sym-
metrical and as direct installation.
D o not remove the temperatur sen-
■
sor if already mounted on the flow
sensor. This is also valid for all the
safety seals which are mounted on
the device as a standard.
S ensors resp. their type labels are
■
partly colour-coded
(according to the model):
Red = Inlet pipe of the plant
(warmer pipe for heating, colder
pipe for cooling)
Blue = Outlet pipe of the plant
(colder pipe for heating, warmer
pipe for cooling)
T he connecting cables may not be
■
buckled, extended or shortened!
The seal at the sensor installation
■
point on the flow sensor may not be
damaged.
R emove locking screw and seal at
■
the ball valve completely, if existing.
I f provided, attach the O-ring to
■
the installation aid (the 2nd O-ring
is only a spare O-ring). Using the
installation aid, insert the O-ring
into the installation point according
to DIN EN 1434 with a slight circular
motion.
Using the other end of the instal-
■
lation aid bring the O-ring into the
correct position.
Mounting with plastic adapter:
■
–
I nsert the 2 halves of the plastic
connector into the sensor's three
notches (grooves) and press them
together.
Use the mounting aid as position-
■
ing aid.
