Installation
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 heat meter the mounting place of the cold side is
equivalent to return
alent to flow
Note: For a cooling meter the mounting place of the hot side is
equivalent to return
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.
Fit the temperature sensors in the same circuit as the meter.
Observe in addition the admixtures.
Seal the temperature sensor and the fittings to protect against manipula-
tion.
If you install the meter for cooling metering, follow the respective notes.
Recommendation: If you are installing several meters, the same installation
conditions must be consistent for all meters.
Note: Observe the local valid installation instructions mounting the
meter.
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 mechanical
shocks or vibrations at the place of installation.
Note: Ensure the electronic unit is protected against any ingress of
water.
