To avoid fire and explosion:
• Flush equipment only in a well-ventilated area.
• Ensure main power is off and hea ter is cool
before flushing.
• Do not turn on heater until fluid lines are clear of
solevent.
To flush feed hoses, pumps, and heaters
separately from heated hoses, set PRESSURE
RELIEF/SPRAY valves (SA, SB) to PRESSURE
RELIEF/CIRC ULA TIO N
. 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 Important Tw o-
