Empty and Flush Entire System
(new system or end of job)
NOTE:
•
If the system includes heaters and heated hose,
turn them off and allow to cool before flushing. Do
not turn on the heaters until the fluid lines are clear
of solvent.
•
Cover fluid containers and use the lowest possible
pressure when flushing to avoid splashing.
•
Before color change or shutdown for storage,
circulate the solvent at a higher flow rate and for a
longer time. Change the solvent when it gets dirty.
•
To only flush the fluid manifold, see
•
If the machine is inoperable, use drain plugs on the
pump inlet fittings.
Guidelines
Flush new systems if the coating materials will be
contaminated by mineral oil. Follow the
on page 38 to ensure mineral oil is removed.

gelling in the pumps, lines, and valves. Flush the system
when any of the following situations occur.
•
Anytime the system will not be used for more
than one week (depending on materials used)
•
If the materials used have fillers that will settle
•
If using materials that are moisture sensitive
•
Before servicing
•
If the machine is going into storage, replace the
flush solvent with light oil. Never leave the
equipment empty of any fluid.
