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.
Keep the lowest regulator away from the pump
suction port so that it will not be sucked in.
If the installation is outside protect the discharge
pipes, the isolating and check valve, and the elec-
tric controls from frost. Connect the cables to the
overload release or to the control box.
