SUBJCET TO CHANGE WITHOUT PRIOR NOTICE
If transmission network interfaces are used, especially when cables are routed outside the building, use more protection
against electrical interference.
In case of danger of frost, empty the system and, if necessary, remove the meter.
Rinse the pipes thoroughly before installing the meter.
The meter shall be installed in the direction of the arrow on the meter housing, corresponding to the direction of the flow.
Avoid collecting air bubbles in the meter during the installation process.
The meter shall not be subjected to mechanical stress when installed in the pipe.
The meter shall be installed in a way that it is protected from all external impurities and contamination.
Remove the old seals and clean the sealing surfaces.
Slightly grease the sealing surfaces (use grease approved for drinking water and acid-free).
The meter can only be installed in frost-proof areas.
Use only the gaskets supplied (the gaskets must not get into the pipe). Seals provided on site must be fit for purpose
and comply with local guidelines and directives. No liability is accepted for consequential damage resulting from the use
of third-party seals, such as corrosion of seal surfaces and threads.
Manually and simultaneously screw the meter fittings on both sides and then tighten in opposite
directions using a suitable tool.
Slowly fill the pipe with water after installation.
The meter must be protected against pressure shocks in the pipe.
