Flushing
• 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 fluid components are compatible with common
solvents. Use only moisture-free solvents.
• To flush feed hoses, pumps, and heaters separately
from heated hoses, set PRESSURE
RELIEF/SPRAY valves (SA, SB) to PRESSURE
RELIEF/CIRCULATION . Flush through bleed
lines (N).
• To flush entire system, circulate through gun fluid
manifold (with manifold removed from gun).
• To prevent moisture from reacting with isocyanate,
always leave the system dry or filled with a mois-
ture-free plasticizer or oil. Do not use water. See
page 6.
Flush equipment only in a well-ventilated area. Do not
spray flammable fluids. Do not turn on heaters while
