8. Grease the threaded ring of the coaxial meter
and screw it into the EAS until it comes to a
firm stop on the housing. Only use a hook
wrench for this purpose! Do not use any
additional sealants under any circumstances!
9. Seal the coaxial meter with the enclosed
sealing wire through the nearest sealing lug
on the measuring capsule and on the EAS
and, if necessary, together with the
temperature sensor in the housing.
10. Open the shut-off devices and check the
installation site for leaks. Then put the heating
system back into operation.

1. Check installation location for completeness.
There must be an all-measurement single-pipe
housing in the return and the original
installation location(s) for the temperature
sensor(s). Caution: In refrigeration systems,
the supply is the colder pipe and the return is
the warmer pipe. The meter to be installed
must then be of the PolluCom
®
F/S C X RA
type with appropriate adjustment. Please
check.
2. Switch off the heating system or its circulation
pump.
3. Close the shut-off valves located upstream
and downstream of the single-pipe adapter
(EAS).
4. Check the installation point again for correct
flow direction (arrow on the housing), correct
its installation if necessary.
5. Unscrew the overflow cap or existing
measuring capsule from the single-tube
housing (C) and remove the O-ring seal
inside.
6. Clean the sealing surfaces of the housing
7. Align PolluCom
®
F/S C RA – measuring
capsule (A) in flow direction (arrows on bottom
of capsule and on single-tube housing, recess
for locking pin).
8. Check pre-assembled seals (body seal and
outlet seal) for correct seating and correct if
necessary.
9. Now insert the coaxial meter straight into the
monotube housing from above and press it in
as far as the bottom. (Fig. 5.5.1)
10. Grease the thread of the screw ring (A 1),
position it straight and screw it into the thread
on the housing; tighten lightly with the
enclosed assembly wrench. Do not use any
other sealants.
11. Screw the temperature sensors into the
corresponding immersion sleeves on the
housing or in the pipe network and seal them.
12. Seal the coaxial meter with the enclosed
sealing wire through the nearest sealing lug
(A2) and, if necessary, together with the
temperature sensor in the housing.
13. Open the shut-off devices and check the
installation site for leaks. Then put the heating
system back into operation.
6. Mounting the temperature sensor
Depending on the version, PolluCom
®
F/S C has
one or two external temperature sensors. The
standard cable length is approx. 1.5 m (special
version: approx. 5 m and approx. 10 m). If possible,
a cable duct or empty conduit should be used for
laying the cable.
Joint installation in cable ducts or on cable trays
with power supply lines is not permitted. The
minimum distance for low-voltage lines according
to EN 1434, part 6, of 50 mm must be complied
with.
After installing the temperature sensors, seal them
to prevent tampering.
