IMPORTANT: Ensure installation, wiring, and control
settings are according to the application
requirements. Refer to the controlled system’s
manufacturer specifications for the proper settings
when adjusting these controls.
Apply power to the control and controlled equipment.
Cycle the controlled system at least three times at
normal operating conditions.
The circuit between the red and the yellow leads
(terminals) closes when sufficient fluid flows through
the pipe to trip the F61 flow switch.
