Suitable and unsuitable installation locations
A, B: OK,
C: not OK - air accumulation in the volume measuring section.
Installation at a high point only if a bleeding option exists.
No installation at a low point!
D: Only OK in closed systems
E: not OK - directly after a restriction or a reducing component
F: not OK - too close on the suction side of a pump
G: not OK - after a bypass loop in two levels
Observe: Distance ≥ 50 cm between the computer unit and possible sources for
electromagnetic interference.
If there are several meters in one unit: Observe identical installation conditions!
When installing the volume measuring section in the shared outlet of two circuits:
Minimum distance from the junction (T-piece) 10 x DN.
Installation positions
horizontal, vertical, at an angle,
up to 45° upwards to the pipe axis
and up to 90° downwards to the pipe axis.
Only install electronics housing upwards if high operating pressure and automatic ventila-
tors are used.
When installed in damp conditions, the meter must be installed rotated 45° to the pipe
axis.
!
If possible, use the same installation method within one property!
We recommend using a strainer in front of the volume measuring section.
Shut-off valves must be installed in front of the strainer and behind the heat meter.
Rinse the conduit thoroughly before installing the meter – use the replacement pipe
section for the meter for this purpose.
If replacing a meter, be sure to clean the sealing surfaces of the screw connection.
Use new seals.
Open the shut-off devices and check their leak-tightness.
Ensure that the ends of the sensors reach at least the middle of the pipe cross-section.
After installation, test for leaks and perform a function check.
The meter starts measurement when flow occurs.
Document the commissioning.
Computer unit installation
The computer unit must be accessible at all times and readable without further aids.
Compact installation (standard)
Installation directly on the volume measuring section. The computer unit is sealed ex-
works.
Wall installation
Required for: medium temperature < 15 °C / > 90 °C • restricted readability
Choose a dry, easily accessible place.
1
Observe the cable lengths of the temperature sensors.
2
Use the wall-mounting plate for marking the two 6 mm drill holes.
