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 their
respective A or B supply drum, or to
grounded metal waste containers.
3. Set the pressure relief/spray valves (SA, SB)
to pressure relief/circulation
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 31. Circulate fluid until only
solvent comes from the bleed lines.
