Safety, Installation and Operations Manual – Translation of original instructions
Float switches allow one or more pumps to be started and stopped in response to the level of liquid in the tank.
They can also be connected to alarm devices to prevent operational problems (overflow or dry running).
They must be installed well away from turbulence or inflows of water.
In the event of strong turbulence, float switches should be installed on a rigid rod mounted inside the pit.
Make sure that there are no items which may obstruct movement of the floats and that the wires do not interfere
with each other, and cannot become tangled or trapped on projections inside the tank.
Float switches must be installed in such a way that the correct minimum liquid level is guaranteed.
