Start-Up; Leak-Testing And Filling The System; Initial Start-Up - OEG SecuFresh 22 Montage- Und Bedienungsanleitung

Complete installation of all hydraulic and electrical components is a precondition for the

start-up.

Check all system components, including all pre-fabricated elements and stations, to
ensure they are leak-tight; seal any detected leaks accordingly. When doing so, 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.
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.
