6.5.3 Hardware and Plumbing Installation

1. Mount the Turbidity Flow Cell, using the supplied bracket (or other mounting hardware as
appropriate) such that the inlet and outlet ports are horizontal and the flow tube extends down.
2. Insert the sensor into the opening of the flow tube, ensuring that the notch in the top of the
opening matches the rod on the sensor.
3. Hand-tighten the connector to secure the sensor and seal the turbidity flow cell.
4. Connect the water supply to the turbidity flow cell. Follow the flow indicated by the arrow on the
flow cell.
The flow rate should be between 0.25 and 1 GPM (15-60 gal/hr or 50-225 L/hr) and the pressure should not
exceed 30psi (2 bar). The inlet and outlet connections are ¼" FNPT.

6.5.4 Electrical Installation

1. Install the Turbidity Module (electronics card) on the inside, bottom of the control panel door
using the supplied screws.
2. Connect the turbidity module to the I/O module using the supplied ribbon cable and any open
connector (the connectors on both boards operate in parallel).
3. Pass the sensor cable through an open glad on the bottom of the controller.
4. Connect the wires from the sensor cable to the terminal block on the lower left corner of the
Turbidity Module, following the color order indicated on the module.
