Complete installation of all hydraulic and electrical components is a precondition for
commissioning.
5.1
Leak testing and filling the system
Check all system components, including all pre-fabricated elements and stations, to ensure
they are leak-tight; seal any detected leaks accordingly. When doing this adapt the test
pressure and test duration to match the respective piping system and the respective
operating pressure.
Fill the drinking water side with clean drinking water as per DIN 1988 only; bleed the air from
the system by gradually increasing the pressure.
Note:
Cavitation may develop as a result of excessive flow speeds; this may damage the flow
sensor.
Only fill the heating system, including the primary side of the fresh water system, with filtered,
treated water as per VDI 2035; bleed the system completely.
