5. Assembly/installation

Assembly/installation must be carried out according to current practice (e.g. EN 1434-6) so that trouble-
free measuring can be implemented.
The meter must only be installed in areas free from the risk of frost. If the meter is thermally insulated,
only the flow meter should be insulated, the calculator must not be insulated. The meter must be fitted in
the pipeline so that it is free from mechanical stresses.
The meter should only be removed from the packaging directly before assembly to protect it against damage
and dirt. If several meters are installed in one unit, then the same installation conditions must be ensured.
Impermissible work
The lead meter seal must not be broken! If the lead seal is broken, the factory guarantee and calibration/
conformity are immediately invalidated. The permanently fitted battery must not be disconnected. Disconnec-
tion of the battery terminals leads to loss of saved data. The temperature sensor cables must not be kinked, shortened
or lengthened, nor changed in any other way. Never carry out hot work (soldering, welding, drilling) close to the meter.
Medium/temperature
The measurement resistance of the meter is only ensured, if the water quality corresponds to the conditions
of the AGFW (The German Energy Efficiency Association for Heating, Cooling and CHP) recommendation
FW-510. The permissible water temperature at the flow sensor must be maintained below the maximum of +90 °C.
Cleaning
Meter cleaning (only when necessary) must only be carried out from the outside with a cloth that has been slightly
moistened with water. Do not use any cleaning agents!
General assembly information
Assembly and disassembly may only be carried out in depressurised pipework sections. At least 20 cm
distance must be maintained between the meter and any electromagnetic sources of interference such
as switches, controllers, pumps, etc. The display must be accessible at all times and be legible without any external
aid. When selecting the installation location, bear in mind the length of the cables to the free temperature sensor.
Measuring capsules only: The plastic blanking cap is not intended for long-term use.
