6.3.4 Drain connection
Rules for safe installation of the drain connection
Observe the following rules to prevent hazards caused by a faulty drain connection:
There must be no restriction or reduction in the cross-section of the waste-water pipe.
The slope of the wastewater pipe must equal min. 3.5% (2°).
If more than one appliance is connected to one wastewater pipe, this pipe must be large enough to
allow the wastewater to flow out unchecked.
The appliance must be connected to the drain using a non-flexible pipe. A permanent connection
is recommended; alternatively an open funnel waste trap can be installed. For table-top units with
a wheeled platform, the waste-water pipe in a permanently connected system must be disconnec‐
ted before the appliance can be moved with the platform.
