2.1 Application scope
The lifting systems pump the wastewater (with and without
faeces) that is collected below the drain and local back-up
level into the sewers fully automatically in compliance with
the stipulations of EN 12056. They may only be used for
household wastewater, for example from detached homes
and apartment buildings, commercial operations, hotels and
restaurants, shops, hospitals, schools or other similar cases.
If the incoming flow to the lifting system may not be inter-
rupted during normal operation, the lifting system also
needs to be equipped with a second pumping device with
the same output level that can switch on automatically if re-
quired (double instead of single system).
