Air barrier connection
In systems with a DN 70 lifter, the air barrier of the clear water lifter must be connected to the sludge re-
turn. This involves disconnecting the sludge return's air pipe at a suitable point and integrating the air
barriers’s air pipe (8 mm) into the sludge return's air pipe using a T-piece.
