Instruction Sheet P/N 0870-0 WARNING: Allow only qualified personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation. Introduction The spray pressure control (SPC) manifold is part of the Nordson Spray Pressure Control system. The manifold houses a fixed orifice (restrictor) that reduces pressure fluctuations in the fluid system. A T-filter is mounted on the manifold upstream from the orifice to prevent contaminants from blocking it. Figure (Shown with Drip Tray) Part 0870-0
2 Installation Recommended Circuit for Spray Pressure Control See Figure 2 for a typical dual spray gun system using Spray Pressure Control. Review this recommended plumbing circuit before installing any parts into the system.

Installation WARNING: Relieve system fluid pressure before installing the SPC manifold. Failure to observe this warning may cause personal injury or equipment damage. NOTE: Restrictors are not included with the SPC manifold, as they are application-specific. Refer to Restrictors on page 6 for a list of available restrictors.. See Figure. Install the manifold with the drain nipple () pointing down. 2. Connect a fluid line from the spray gun output to the /2 20 JIC inlet connector (9).. Connect a fluid line from the /2 20 JIC outlet connector (8) to the fluid return line to the pump.. After you have installed the manifold, flush the fluid delivery system to remove any contaminants from the system. 5. Remove the restrictor holder (), install a restrictor and seal (A), then install the holder back in the manifold. See Figure 5 for restrictor installation. 9 8 A 6 Figure Installation (item numbers match item numbers in parts list). Restrictor holder 8. Connector /2 20 JIC A. Restrictor and seal 9.
