Flush Mixed Ma
terial
There are times when you only want to purge the mix
manifold and gun, such as:
• end of potli
fe
•breaksinsp
raying that exceed the potlife
• overnight
shutdown or end of shift
• before ser
vicing the mix manifold, hose or gun.
1. Press Standby
.
2. If you are using a high pressure gun or an
electrostatic gun, shut off the atomizing air.
If you ar
e using a high pressure gun, engage
the tri
gger lock. Remove the spray tip and
clean i
t separately.
If using an electrostatic gun, shut off the
electrostatics before flushing the gun.
3. Trigger the gun to relieve pressure.
4. Set the solvent supply pressure regulator at the
lowest pressure possible, to avoid splashing or
an injection injury. Generally a setting of 25–50
psi (0.18–0.35 MPa, 1.8–3.5 bar) is sufficient.
5. Set the mix manifold to the FLUSH position.
6. Press Purg
e
. Trigger the gun into
a grounded
metal pail until the purge sequence
is complet
e. When done purging, the system
automati
cally switches to Standby mode,
signalli
ng the user to release the trigger.
7. If the sys
tem is not completely clean, repeat.
NOTE: Fo
r optimal efficiency, adjust purge
sequenc
e times so only one cycle is required.
8. Trigger
the gun to relieve pressure. Engage the
trigger
lock.
9. If the s
pray tip was removed, reinstall it.
10. Adjust
the solvent supply regulator back to its
normal
operating pressure.
