Empty and Flush Entire System (new system or end of job)
7. For XP Systems only: Open the main air shutoff
valve (CA).
CB
NOTE: If the system does not start with static pres-
sure, increase the air pressure by 5 psi (35 kPa,
0.35 bar) increments. To avoid splashing, do not
exceed 35 psi (241 kPa, 2.4 bar).
8. Run the pumps until the A and B hoppers (J) are
empty. Salvage the material in separate, clean con-
tainers.
9. For XP Systems: Close the main air shutoff valve
(CA).
10. For XP-h Systems: Set pump valve to off.
11. Wipe the hoppers (J) clean, then add solvent to
each. Move the circulation lines (U) to waste con-
tainers and push out the dirty fluids.
12. Move the recirculation lines (U) back to the hoppers.
Continue recirculating until the system is thoroughly
flushed.
J
13. Close the circulation handle (AC) and open the dual
shutoff handle (AE).

14. Dispense fresh solvent through the mix manifold
valves and out the gun.
15. Turn off the air motors and follow Pressure Relief
Procedure, page 24.
16. Close the dual shutoff handle (AE).
17. Remove pump fluid filters, if installed, and soak in
solvent. Clean and replace the filter cap. Always
replace the filter o-rings.
NOTE:
• Fill the A and B pump packing nuts with TSL.
Also, always leave some type of fluid, such as
solvent or oil, in the system to prevent scale
build up. This build up can flake off later. Do not
use water.
• If machine is set up with a remote mix manifold,
the A and B hose can be disconnected from the
mix manifold, and secured in back of each hop-
per for circulation of flush solvent.
• Change the flush solvent at least once until it
circulates clean.
• Always keep the A side and B side flush solvent
separate.
