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-

The dirt traps should also be checked after the filling process or after extended opera-
tion.
