Installation flow sensor (FS)
■
Mount 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).
■
Consider the correct flow direction.
This is indicated by an arrow on the
side of the flow sensor.
■
The 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 ball valve
■
Mount ball valves up- and down
-
stream of the meter.
■
Mount a ball valve with bore M10x1
for the temperature sensor instal-
lation.
■
For symmetrical temperature sen
-
sor installation, mount a second
identical ball valve.
Mounting heat/cooling energy meter
■
Flush the system thoroughly before
installing the meter.
■
Close valves and release pressure.
■
Dismount the existing flow sensor
/ fitting.
■
Use only new and flawless sealing
material, no hemp or similar! Clean
sealing surfaces and check for
damage.
■
Install the new flow sensor accord
-
ing to the correct flow direction and
installation position.
■
Turn heat computer to desired read-
ing position.
Installation of the temperature sensors
■
The installation of the temperature
sensors should be preferably sym
-
metrical and as direct installation.
■
Do 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.
■
Sensors 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)
■
The connecting cables may not be
buckled, extended or shortened!
■
The seal at the sensor installation
point on the flow sensor may not be
damaged.
■
Remove locking screw and seal at
the ball valve completely, if existing.
■
If 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:
–
Insert 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.
