- Route the flow switch electrical cable through the hole in the unit structure and run it to the electrical panel by
ascending the upright in the machine interior. Connect the flow switch to terminals 1-14 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 figure10).
