Flow Switch Maintenance

If you have the flow switch plumbing assembly, you may need to periodically clean the wetted parts in
this assembly.

  Shut off the inlet flow and the power to the controller.
  Turn the coupling nut for the flow switch counterclockwise.
  Pull out the red shuttle with your fingers.
  Use a bottlebrush on the shuttle, flow sight and the flow switch assembly to remove any

residue.

Clean and lubricate the ―O‖ ring with a silicone-based lubricant (petroleum-based
lubricants will cause the O-ring to swell).

Tighten down the coupling nut after you replace the components.
Turn the inlet flow back on and check for leaks.
