Flush Flush the Equipment
To help prevent fire and explosion:
• Flush equipment only in a well-ventilated
area.
• Do not spray flammable fluids.
• Do not turn on heaters while flushing with
flammable solvents.
• Always ground equipment and waste
container.
• Flush out old fluid with new fluid, or flush
out old fluid with a compatible solvent
before introducing new fluid.
• Use the lowest possible pressure when
flushing.
• All wetted parts are compatible with
common solvents. Use only moisture-free
solvents.

1. Install bleed lines between the outlet
manifold recirculation fitting and a grounded
metal waste container.
2. Route the circulation lines back to respective
A or B supply, or grounded metal waste
containers.

4. Use jog mode to circulate fluid. Reactor
systems allow the entire system to be in
jog mode, or A and B-side transfer pumps
to be put into jog mode separately. See
Jog Mode, page 33. Circulate fluid until only
solvent comes from the bleed lines. The
Reactor feed hoses, pumps, and heaters are
now flushed.

6. Hold the gun fluid manifold over
two grounded waste containers.

the valves. The Reactor hose and gun
manifold are now flushed.
NOTE: NOTE: NOTE: For the estimated number of machine
cycles needed to flush different models and
hose configurations, see the table on the
