4.4 Connecting AI to the drain with pn:60045416
Ø50mm drain pipes are used to connect the AI to the waste water system. The
pn:60045416 includes modified plug with cable glands and a 67° ø50 single branch.
The extra opening of the single branch is used as an overflow and occasionally to flush the
drain pipes with hot water (for cleaning).
When the AI waste tube (ø10) is fixed in the drain it is important to keep the end of the
tube visible trough the overflow but still above the highest possible water level.
Furthermore it is important that the ø10 tube has a positive slope all the way from the AI
to the drain.
The mainline tube (ø4) should be fixed with the end below the overflow (to prevent
splatter).
