Pressure Relief Procedure
310796F 9
Alternate Pressure Relief
Procedure
7.
Flush mix manifold, hoses, and gun, see manual
310797. Shut off solvent supply pump and repeat
steps 4-6 to relieve solvent pressure.
8.
If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after fol-
lowing the steps above, very slowly loosen tip
guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
hose or tip obstruction.
9.
If static mixer, whip hose, and gun cannot be
flushed because of mixed and cured material, very
slowly loosen static mixer tube from mix manifold
outlet to relieve pressure gradually, then loosen
completely. Replace or clean clogged components.
Use this procedure if your system includes Circula-
tion and Return Tube Kit 246978 (see manual
309852), to relieve fluid pressure back to the supply
drums. This method allows:
• fluid pressure relief without flushing the mixer,
hose, and gun again
• circulation back to drums after a drum change,
to purge air from feed pumps and lines
• if using drum heaters, warm material may be
circulated through proportioner before begin-
ning to spray.
CAUTION
Do not circulate contaminated material back to the
drums.
1.
Follow steps 1-6 under Pressure Relief Proce-
dure, page 8.
2.
Turn SPRAY/PRESSURE RELIEF valves to PRES-
SURE RELIEF (hardener valve must be opened
first).
