4.On the Manual Override Screen, drive the regula- tor to a percentage open that starts fluid flow. Fluid pressure should be above 12 psi (.08 MPa, 0.84 bar) [see the Status Screen]. Observe the fluid flow rate at this pressure. This is the achievable low end flow rate for the system’s given restriction. If a lower flow rate is required, increase the restriction between the flow control regulator and the spray gun.

NOTE: If the lowest flow rate achieved is well below 12 psi (.08 MPa, 0.84 bar), add restriction to achieve fluid pressure closer to 12 psi. Pressures below 12 psi can be inconsistent.

5.Drive the regulator to 100% open. This is the maxi- mum achievable flow rate based on the low flow requirement and the flow control module’s functional range.

6.When an acceptable operating range is achieved, turn Flow Control Override Off.
