6.2 Electric panel level switches
During operation the electropump must be immersed in the pumped liquid. It is necessary to install a
control system with level switches (level probes or floats or other appliances) that ensure the minimum
level of liquid and protect the electropump against dry running.
When installing the level switches, observe the following points:
To prevent air intake and vibrations install the
stop level switch
in such a way that the pump is stopped
before the liquid level is lowered below the top of the cable entry.
