Clean dirt traps
Caution! Observe general safety instructions (→ p. 5)!
Note:
After expiry of the set permanent deaeration period, clean the dirt traps of the pressure
reducing valves (5, 8) of the make-up and overflow lines (not part of reflex commissio-
ning!). Do not forget dirt traps (for instance ’fillset’ item F) installed by customer.
If the dirt traps are very dirty, fine setting (hydraulic balancing → p. 13) is required once
more.
The dirt traps should also be checked after the filling process or after extended opera-
tion.
