•
Observe the dimensions of the meter and check whether
there is sufficient space available. Rinse the system thor-
oughly 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.
Note: Only use the flat seals that are supplied.
•
The meter must not be exposed tensions or forces caused
by by pipes or fittings. If this cannot be permanently guar-
anteed, it is necessary to improve the point of installation or
fix the lines in position, by means of suitable connecting
brackets for example.
•
Fit the temperature sensors in the same circuit as the me-
ter. Observe the 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 thorough mixing of the
different water temperatures. You can install the temperature
sensors in T-pieces, ball valves, directly immersed or in pock-
ets 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 im-
pacts or vibrations at the place of installation.
•
Use two open-ended spanners to install the meter. Position
the open-ended spanners only at the gripping areas pro-
vided.
•
Note and use the tightening torques given in the following
table and the corresponding angle from contact of the union
nut with the gasket:

•
On activation, open the slide valves slowly.
Recommendation: Do not install the meter on the pressure
side of a pump. Maintain a minimum distance of 10 x DN on
the pressure side.
Note: During installation it must be ensured that no
water can enter the electronic unit during operation.
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.
