Flush Mixed Material
This procedure flushes out mixed material from system
to prevent it from curing in the system.
NOTE: Pot life of the mixed materials in the system is
much shorter than the dry time of dispensed epoxy
because mixed material potlife or working time
decreases with increased temperature.
Follow this procedure when you are finished spraying if
the potlife of the mixed materials in the system could
expire before you spray again.
1. If necessary, Prime Flush Pump, page 36.
2. Press to stop the metering pumps.
3. Trigger gun into a waste container to relieve
pressure then engage trigger lock.
4. Remove spray tip.
5. Close mix manifold ball valves.
6. Open one of the flush ball valves on the mix
manifold.
7. Disengage trigger lock and trigger gun into a
grounded pail. Use a pail lid with a hole to dispense
through. Seal around hole and gun with a rag to
prevent splash back.
8. Open flush pump air supply valve (CB). Pull out and
slowly turn flush pump air regulator (CG) clockwise
to increase air pressure. Use lowest pressure
needed to flush material out of hose.
9. Continue dispensing until clean flushing fluid is
dispensed.
10. Close the open flush valve. Open the other flush
valve. Continue dispensing long enough for any
remaining mixed material
11. Close flush pump air supply valve.
12. Trigger gun to relieve pressure in flush lines then
engage trigger lock.
To avoid fire and explosion:
• Flush equipment only in a well-ventilated area
• Ensure main power is off and heater is cool before
flushing
• Do not turn on heater until fluid lines are clear of
solvent
