6.6 Installation and adjustment of the float switch
The float switch cable is housed in the same protective conduit as the intake line, for easy access and
protection from damage. Therefor it is necessary to disconnect the cable from the pump terminal. Don’t
forget to fit the cable gland for the fixing point.
The fixing point for the float switch cable is installed in an
accessible area of the tank opening so that it is possible to
access (such as for inspection and maintenance purposes)
even with a full tank level. The necessary height can be
adjusted by means if the built-in cable gland.
The intake line is installed in such a way that the floating ball
just touches the bottom of the empty tank (see Chapter 6.3.4).
The float switch counter weight (A) is mounted 15 cm above
the float switch. The safety distance between the intake filter
and the bottom of the float switch must be at least 10 cm (B),
allowing the float switch enough cable length for free
movement.
The float switch is electrically connected to the base controller
(see Section 5.1).
Note:
The distance to all inner mounted parts in the cistern must
be selected in such a way that the float switch can freely
float.
