Complete installation of all hydraulic and electrical components is a precondition for commis-
sioning.
6.1
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 pres-
sure and test duration to match the respective piping system and the respective operating
pressure.
6.1.1
Drinking water side
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. Open all taps and fully bleed the drinking
water side.
Note:
Cavitation may develop as a result of excessive flow speeds; this may damage the flow sen-
sor.
6.1.2
Heating side
Only fill the heating system, including the primary side of the fresh water system, with filtered,
possibly treated water as per VDI 2035; bleed the system completely.
6.2
Starting up the system for the first time
Observe the corresponding operating manual when starting up the control unit.
