4.1 Applications
Pumps for lifting of domestic waste water:
– sewage, rainwater containing sludge and parti-
cles (except rigid particles) with traces of hydro-
carbon, detergent.
– For fixed installation in a sump or a tank.

cable of less than 10 metres are (according to EN
60335) only permitted for use inside buildings,
i.e. not for operating outside.
CAUTION! The pump must not be used for
pumping drinking water.

6. Assembly/Installation
6.1 Installation
– Fig. 1: Installation of a pump with single-phase
motor, float switch and optional overflow audible
signal.
– Fig. 2: Fixed installation of 2 pumps connected
to a collector for twinned pumps and operating-
contol by 4 float switches.
NOTICE:
Cut-out level:
For intermitted duty:
H min = 40 mm short-term,
For continuous duty:
H1 min = 230 mm (Fig. 1-2)
The shaft should be of ample size, so that the
motor does not start too often.
NOTICE:
Lower the pump into the sump using a chain (or a
rope) hooked to the handle, never by its power-
or float switch cable.
Take care not to damage the power cable of the
motor during the going down in the sump.
Avoid placing the regulators near the outlet of
the pipe through which the water enters the
sump, since this could mover them.
