1 Air distributor 4
Air distributor / intake line flange con -
nection
2 Intake line 5 Connection flange of the aerator pipes
3 Base support
1. Place the air distributor into the pipe clamp of the base support so that the flange con -
nection is pointing straight upwards.
2. Slide the air distributor to the left or right until the flange connection is positioned
directly under the connection flange of the intake line.
Important: The air distributor must be easily slid under the supply pipe. The two
flanges may not twist, and the distance between them may not be larger than 1 mm.
The height of the base support may need to be adjusted.
3. Screw the two flanges onto each other and tighten the screws securely.
4. The connections for the aerator pipes must be precisely horizontal so that the connect
-
ed aerator pipes run horizontally.
5.4.6. Installing the aerator pipes
The aerator pipes are installed using pipe couplings. A differentiation must be made
here between the installations “aerator pipe / aerator pipe” and “aerator pipe / air dis
-
tributor.” For connecting two aerator pipes, the pipe couplings are used purely as plug
connections. When connecting the aerator pipes to the air distributor, the pipe coupling
is additionally secured on the side of the air distributor using a pipe clamp.

2 Aerator pipe with disc aerator
1. Clean the outside of the pipe ends of the aerator pipe as well as the inside of the pipe
coupling.
2. Check the round sealing rings in the pipe coupling for damage. Defective seals must be
replaced.
3. Wet the outside of the pipe ends of the aerator pipe as well as the inside of the pipe
coupling with a liquid soap solution
(do not use grease or oil)
.
4. Fit the pipe coupling onto an aerator pipe. Slide the pipe coupling up to the first marking
on the aerator pipe.
