Flushing
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 a solvent pump to the fluid manifold.
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 3-1/2 hours
(depends on material)
•
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 18.
WARNING
Read warnings, page 5.
•
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.
•
A circulation setting is available. Consult your
distributor. Refer to page 27.
