Installation Notes
To install the meter proceed as follows:
•
Determine the place of installation in line with the inscription on the meter.
Note: For a heating meter the mounting place of the flow sensor
cold side is equivalent to return
flow sensor hot side is equivalent to flow
Note: For a cooling meter the mounting place of the flow sensor
hot side is equivalent to the return
flow sensor cold side is equivalent to flow
•
Observe the dimensions of the meter and check whether there is sufficient
space available.
•
Rinse the system thoroughly before installing the meter.
•
Fit the meter vertically or horizontally between two slide valves so that the
arrow on the housing and the flow direction match. Also observe the instal-
lation situations and the following examples of installation.
Note: Only use the rubber EPDM flat seals that are supplied.
•
The meter must not be exposed to tensions or forces caused by pipes or fit-
tings. If this cannot be permanently guaranteed, it is necessary to improve
the point of installation or fix the lines in position, by means of suitable con-
necting brackets for example.
•
Fit the temperature sensors in the same circuit as the meter.
•
Seal the temperature sensor and the fittings to protect against manipula-
tion.
•
If you install the meter for cooling metering, follow the appropriate notes.
Recommendation: If you are installing several meters, the same installation
conditions must be consistent for all meters.
Inlet or outlet sections are not necessary. If you install the meter in the com-
mon return of two circuits, determine a place of installation with a minimum
distance of 10 × DN from the T-piece. This distance ensures a good thorough
mixing of the different water temperatures. You can install the temperature
sensors in T-pieces, ball valves, directly immersed or in pockets depending on
the version. The temperature sensor ends must reach to at least the middle of
the pipe cross section.
Note: Protect the meter against damage through impacts or vibra-
tions at the place of installation.
