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 possi-
ble 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 Flush Mix
Manifold, Hose, and Spray Gun, page 30.
•
If the machine is inoperable, use drain plugs on
the pump inlet fittings.
Guidelines
Flush new systems if the coating materials will be con-
taminated by mineral oil.
Flushing will help prevent materials from settling or gell-
ing 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.
