b. The flow switch verifies that water is flowing during a feed
cycle, and sends the controller instructions to deactivate
the feed if water is not flowing.
c. Operation of this controller without a functioning flow-
switch will void the NSF Certification. Routinely check that
the flow-switch is functioning by closing the left valve on
the bottom of the flow-cell (flow light should turn off).
