- The flow switch must be tightened on the “T” shaped metallic manifold by the plastic knurled union nut. Check
that the arrow located on the upper side is pointing in the direction of flow.Be sure to fit the O-ring seal, through
the brass manifold and the plastic ring nut. The O-ring seal is supplied in a plastic cover to protect the flow
switch shaft.
- Connect the hydraulic circuit at the other end of “T” manifold. Connect the flow switch cable to terminals 1-14
in the terminal box, as indicated on the electrical drawing.
- The flow switch can be removed by screwing out the plastic knurled union nut. In order to reassemble it ensure
that the O-ring seal is positioned in the proper location. (See figure7).
