Flush the Equipment
To flush feed hoses, pumps, heaters, hose,
and gun manifold:
1. Install bleed lines between the outlet manifold
recirculation fitting and a grounded metal waste
container.
2. Route the circulation lines back to respective
solvent A or B supply. or 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. Refer to the jog mode instructions in
your operations manual. Circulate fluid until only
solvent comes from the bleed lines. The Reactor
feed hoses, pumps, and heaters are now flushed.
5. Set the pressure relief/spray valves (SA, SB) to
spray .
6. Hold the gun fluid manifold over two grounded
waste containers. Open fluid valves XA and XB (see
page 15) until only solvent flows from the valves.
Close the valves. The Reactor hose and gun
manifold are now flushed.
7. Optional: Use accessory circulation kit to circulate
fluid through the gun manifold.
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.

To prevent moisture from reacting with isocyanate,
always leave the system filled with a moisture-free
plasticizer or oil. Do not use water. Never leave the
system dry. See Important Isocyanate Information
