Installation

Install the Back Pressure Regulator (High Pressure Systems Only)

NOTE: The back pressure regulator is required on high pressure systems to prevent the system’s feed pumps from overdriving the dosing pumps during color change pump flush and color fill operations. Adjust the back pressure during the dump process to be approximately 75% of the supply pressure from the feed pumps, but never more than 300 psi (2.1 MPa, 21 bar) less than the supply pressure.

Install the back pressure regulator (120) and attaching hardware at the dump valve of the outlet manifold stack.

1.Install the gauge (123) in the open port of the tee (122).

2.Screw the tee (122) onto the dump valve fitting of the outlet manifold stack.

3.Assemble the two nipples (121) to the back pressure regulator (120). Screw the regulator assembly into the tee (122) as shown.

4.Connect a 1/4 npt(f) dump line to the downward facing nipple (121).

5.Connect the fluid supply lines to the valves. See Connect the Fluid Lines, page 26.
