1. General
This guide is intended for trained specialised personnel. For this reason no
basic working steps are included.
The meter tamper-evident seal must not be damaged!
A damaged seal will result in immediate invalidation of the factory
warranty and verication or declaration of conformity. The cables
supplied with the meter must neither be shortened, extended
nor changed in any other way.
The regulations on the use of energy meters must be observed!
The installation must only be carried out by a specialist company.
The personnel must be trained in the installation and handling of
electrical equipment.
Medium
Water according to AGFW-Worksheet FW510 (the lifecycle of the
meter may be impaired if not observed).
The temperature range depends on variant and nominal size.
Detailed user guide available at http://www.diehl.com/en/diehl-metering/
products-solutions/product-download/.
This user guide must be observed without fail.
The IZAR@SET software is used for readout/parametrization and is
available online at http://www.diehl.com/en/diehl-metering/products-
solutions/product-download/.
Please select the partner "Diehl Metering GmbH" and the product area "
Metering Systems".

1.1 Operating conditions
The temperature conditions for the ow sensor and the tempera-
ture sensor depend on the application and can be found on the
printing of the meter.
Climatic conditions
The ambient temperature must be between 5…55 °C.
Temperatures > 35 °C have a positive effect on battery lifetime.
2. Transport and storage
Unpacking
Energy meter are measuring devices and must be handled with care. To
protect against damage and soiling, they should only be unpacked imme-
diately prior to installation.
Transport
The transport of the meter is permitted only in the original package.
When sending wireless measuring instruments / components by
air, deactivate the wireless before shipping.
Storage
The meter must only be stored in a dry location.
Typical storage temperature +5 °C ... 55 °C
Maximum storage temperature -20 °C ... 60 °C (dry, duration up to
4 weeks)
Relative humid environment < 93 %

3. Assembly / installation
The meter may only be installed in frost-free spaces. Be careful
of sharp edges.
Assembly and disassembly only in depressurised system.
The meter is to be protected against damages due to impacts
and vibrations.
The pipelines are to be attached before and behind the meter.
Pipes for measuring signals are to be installed far away from
other power lines.
When choosing the installation location, make sure that the
meter is perfectly accessible for service and operating personnel.
It is recommended that shut-off valves are tted before and after
the meter to simplify removing the meter.
3.1 Preparatory work
1. Rinse the conduit thoroughly.
2. Close the stop valves upstream and downstream of the meter and
depressurise the pipeline.
It is recommended to install a dirt trap in front of the ow sensor
or at another suitable position of the circulation.
No inlet or outlet path is necessary for the installation of a ow
sensor.
With heating systems without temperature mixing or temperature strati-
cation, the pre-connection of a feeding length of 3-10 DN in front of the
meter is recommended.

3.2 Installing the ow sensor
During heat application, Twater > Tambient must be permanent.
During cold application or with Twater < Tambient variant cooling
meter is to be used.
Mounting position / Position
The meter can be installed in both horizontal and vertical pipe sec-
tions (see g. I).
We recommend installing the ow sensor in a tilted position, to trans-
port possible air bubbles from the circulation(see g. II).
Install the ow sensor so that the ow direction matches the arrow
direction on the sensor (see g. III).
Depending on the version, the ow sensor must be installed in ow
or return. The installation position is displayed in the info loop 3.4
(see "Information loop (3)" at page 15) and also by means of a
pictogram.
Flow Return
Please make sure that the ow sensor is always lled with water.
The meter measures only the energy of completely lled pipe-
lines. Otherwise a corresponding error message is shown in the
display.
The minimum system pressure to avoid cavitation is 1 bar.

3.3 Fitting the temperature sensor pair
The meter is only sold with separately approved temperature
sensor pairs of type Pt 500.
Handle the temperature sensor carefully!
The sensor cables are provided with coloured type plates:
Red: sensor in the hot line
Blue: sensor in the cold line
The connecting lines of the temperature sensors, may not be
shortened or extended.
A common routing in cable conduits or on cable racks with power
supply lines are not admissible.
The minimum distance for low voltage cables according to EN 1434 - 6 of
50 mm must be observed.
3.3.1 Installation in the ball valve with adapter
(coupling set in a separate bag)
Use ball valves with installation option for temperature sensor with thread
M10 x 1.
Preparatory measures
Close the ball valve.
Unscrew the plug screw from the ball valve.
Installation (see g. IV)
1. Place the O-ring from the attached coupling set (type A or B) on the
mounting pin.
2. Insert the O-ring with the mounting pin into the sensor hole of the ball
valve (turn the mounting pin).
3. Position the O-ring in its nal position using the other end of the
mounting pin.
4. Fastening screws
Type A (plastic) - put the fastening screw onto the temperature sen-
sor.
-10-
English Italiano Dansk Svenska
Type B (brass) - slide the fastening screw onto the temperature sen-
sor and attach the fastening screw with the dowel pin. Press in the
dowel pin completely and remove the mounting pin from the tem-
perature sensor.
5. Insert the temperature sensor with adapter tting into the ball valve
and tighten fastening screw by hand (2-3 Nm).
3.3.2 Installation in a pocket
In case of new installations, temperature sensors for nominal sizes DN25
or smaller should only be installed immersed.
This ensures higher measuring accuracy.
3.4 Installing the integrator
Pay attention to sufcient distance between integrator and pos-
sible electromagnetic sources of interference (switches, electric
motors, uorescent lamp, etc.) during installation.
For medium temperatures from 90 °C or for TWater < TAmbient (cooling
meter application) the integrator must be removed and tted at a suf-
cient distance from any heat/cold sources. The adapters VI A or VI B are
available.
3.5 Functional testing
After installation of the meter, putting into operation and functional test-
ing can be performed.
Proceed as follows:
Open the stop valves
Check system for tightness
Bleed the system till the ow indication is stable. Adjust the system by
means of the ow indication
After a short while the message "E-7" disappears in the display.
Press the push button next to the display and check the displays for
temperature and ow for plausibility.
Attach tampering protection at the integrator and the temperature
sensors.
Read and note meter data for energy, volume and serial number.
