Putting into service
Putting a system into service may only be performed by qualified persons. All operating
instructions must be read and followed before putting into service for the first time.
In addition, it must be checked that the installation work was performed correctly.
WARNING: The pipe system must be vented, as air bubbles can lead to explosions
if pressure is suddenly built up. Therefore, the operating pressure should be built
up in stages.
Application errors can result in danger to life due to parts that come loose!
