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.
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 4-5 oz. (120-150 cc) of mate-
rial as it may not be thoroughly mixed due to alarms
while priming the system.
NOTICE
Purge the sampling valves with solvent immediately
after using them to keep material from hardening
inside.
