Flushing
To avoid fire and explosion:
• Flush equipment only in a well-ventilated
area.
• Do not turn on heaters until fluid lines are
clear of solvent.
• 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 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
filled with a moisture-free plasticizer
or oil. Do not use water. Never leave
the system dry. See
