Installation and Operating Instructions

Series FSW Free-Floating Level Switch is a

dual level switch designed for filling and draining

of tanks, wells, and reservoirs. The shape and

interior balance weight ensure impurities and dirt

will not adhere to the surface, making it ideal for

sewage and waste water applications. The

mercury-free switch is designed with an inverter

microswitch housed in a polypropylene cover.

INSTALLATION

The unit should be installed in a vertical position.

Secure the cable with a small clamp in the

reservoir or container. Stress and mechanical

tension must be prevented when installing to

ensure proper operation. Be sure the cable avoids

any jagged edges that may wear at it.

Any extensions to the cable, must be performed

outside the reservoir or tank that the unit is

mounted in. (Other cable lengths are available,

please contact the factory). If the cable must be

extended on site, use a splice connection box to

seal the splice in the cable and prevent water

and/or humidity from damaging the unit.
