Flushing
There are times when you only want to flush the fluid
manifold, such as:
• breaks in spraying
• overnight shutdown
• end of potlife
In this manual, that procedure is referred to as Fluid
Manifold Flushing. You can flush the fluid manifold by
connecting either a:
• solvent pump to the fluid manifold or
• hose and solvent siphon tube to pump A
Other times, you need to flush the entire system:
• first time material is loaded into equipment*
• color change
•servicing
• shutting down equipment for more than 24 hours
• putting equipment into storage
* Some Full System Flushing steps are not necessary for
initial flushing, as no material has been loaded into the sys-
tem yet.
To flush the entire system, you first follow the Fluid
Manifold Flushing procedure, at right, then the Full
System Flushing procedure, page 16.

hose, turn them off and allow to cool before
flushing. Do not turn on heaters until fluid
lines are clear of solvent.
• Use the lowest possible pressure when flush-
ing to avoid splashing.
• Before color change or shutdown for storage,
flush at a higher flow rate and for a longer
time.
• To only flush fluid manifold, see following pro-
