•
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 direc-
tion match. Also observe the installation situations and the
following examples of installation.
•
Fit the temperature sensors in the same circuit as the me-
ter. Please observe admixtures.
•
Seal the temperature sensor and the fittings to protect
against manipulation.
•
If you install the meter for cooling metering, follow the ap-
propriate notes.
Recommendation: If you are installing several meters, the
same installation conditions must be consistent for all meters.
Change mounting place
Note: The mounting place is locked and can't be
changed after the meter has detected a volume of 10
liters. As a result, the "P" disappears from the display:
or
For meters with adjustable mounting place, the mounting place
can be set manually. Proceed as follows:
•
Hold the button several times long (for more than 3 s) until
appears on the LCD.
•
Press the button briefly repeatedly until
appears on the LCD.
•
To change the mounting place, press the button longer
(more than 3 sec). The LCD display changes.
The change happens automatically. The mounting place is
locked and can't be changed after the meter has detected a
volume of 10 liters.
•
Adjust the temperature sensors according to the installation
requirements.
Installation notes
Note: When installing the meter, the locally applicable
installation regulations for meters must be observed.
Inlet or outlet sections are not necessary. If you install the
meter in the common 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 mixing of the different
water temperatures. You can install the temperature sensors in
T-pieces, ball valves, directly immersed or in pockets depend-
ing 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 vibrations at the place of installation.
Note: Ensure the electronic unit is protected against any
ingress of water.
Recommendation: Do not install the meter on the intake side
of a pump. Maintain a minimum distance of 10 x DN on the
outlet side.
Examples of installation (directly immersed sensor)
You can install the meter in any position e.g. vertically or hori-
zontally. In order to avoid accumulation of air and disruption in
operation, fit the meter in a vertical installation position and not
in the uppermost area of a pipeline.

Installation notes for sensor adapter set
A mounting set is included for meters with 5.2 × 45 mm tem-
perature sensors. With this you can fit the temperature sensor
directly immersed into an insert or a ball valve for example.
1.
Use the fit-up aid/pen provided to mount the O-ring at the
installation point.
2.
Place both halves of the plastic bolting round the 3 notches
of the temperature sensor.
3.
Press the bolting together and screw the bolting hand tight
into
the
(tightening torque 3 ... 5 Nm).
