Installation flow sensor (FS)

Mount ball valves up- and down-
■
stream of the flow sensor.
Consider the correct installation
■
point. Normally this is the return
(the colder pipe in heating sys-
tems). Please note the type plate
information.
C onsider the correct flow direc-
■
tion. 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
■
heat 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
installation.
For symmetrical temperature sen-
■
sor installation, mount a second
identical ball valve.

Mounting heat/cooling energy meter

Flush the system thoroughly
■
before installing the heat/cooling
energy meter.
Close valves and release pressure.
■
D ismount the existing flow sensor
■
/ fitting.
U se only new and flawless sealing
■
material, no hemp or similar!
Clean sealing surfaces and check
for damage.
I nstall the new flow sensor ac-
■
cording to the correct flow direc-
tion and installation position.

Return
Symmetrical sensor installation for
zelsius® C5-IUF
Turn heat computer to desired
reading position.
The installation of the tempera-
ture sensors should be prefer-
ably symmetrical and as direct
installation.
Do not remove the temperatur
sensor 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 are colour-coded
(according to the model):
Red = Pipe with higher tempera-
ture level (supply in „Heating"
mode and return in „Cooling"
mode)
Blue = Pipe with lower tempera-
ture level (return in „Heating"
mode and supply in „Cooling"
mode)
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.
R emove locking screw and seal
at the ball valve completely, if
existing.
Attach the O-ring to the installa-
tion aid (the 2nd O-ring is only a
spare O-ring). Using the installa-
tion 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.
