Flushing
16 309908G
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.

If the pump does not start when you trigger the
gun, increase the air pressure by 10 psi (69 kPa,
0.7 bar) increments; to avoid splashing, do not
exceed 70 psi (483 kPa, 4.8 bar). If the pump still
does not start, the solvent may have caused your
packings to swell and it is recommended you use
Tuff Stack™Packing Kit.
