Flushing
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.
• 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
