4.1 Installation of the ORP and pH Sensor
onto the Flow Switch Assembly
1. Unpack the sensors and remove the protective bottle
and o-ring.
2. Set aside the o-rings and save the bottles for
winterizing or reshipping.
3. Remove the compression fitting nut from the flow
cell and slide it up onto the sensor.
4. Slide the o-ring from the bottle onto the sensor.
5. Insert the sensor into the compression fitting on the
flow cell assembly. The sensor tips should extend
below the water line in the flow cell. See Figure 9.
6. Hand-tighten the nut of the fitting, do not use a
wrench.
7. Coil any extra sensor cable externally, not in the
controller box.
