Operation
Purging
Follow the purging procedure in the proportioner system manual.
NOTES:
•Purge before using equipment, which was tested with lightweight oil that could contaminate your material.
•Purge before changing colors, before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment.
•Purge at the lowest pressure possible. Check con- nectors for leaks and tighten as necessary.
•Use a cleaning fluid that is compatible with the fluid being dispensed and the equipment wetted parts.
NOTICE
Purge the sampling valves with solvent immediately after using them to keep material from hardening inside.
Operation
Operation Guidelines
Manifold operation is dependent on the system it is con- nected to. Follow the system operation instructions.
NOTE: After the system has been shut down for a period of time, it is normal for component solenoids and valves to cycle rapidly until system pressure is built back up when restarted.
•Purge air from fluid lines when components are loaded.
•Adjust fluid supply pressure if the fluid output is too low or too high.
•Adjust flow rate with fluid supply pressure regula- tors (optional) or dispense valves. Flow rate should be the same at the spray gun regardless of whether component dispense valves are open. Pressure adjustments of each component will vary with fluid viscosity. Start with the same fluid pressures, then adjust as needed. See Mix Manifold Valve Set- tings, page 8.
•Adjust gun atomizing air pressure as needed.
NOTE: Do not use the first
