3. Remove and clean the bell (follow the steps
under "Shutdown" in the "Operation" section).
4. Place the gun (bell angled down) on the gun
support rack to prevent solvent and paint from
getting into the unit.
5. Flush the paint hose, gun, and feed tube with
solvent. Check the equipment frequently after
the initial installation and establish flushing
The frequency of flushing depends upon:
† Paint type
† Paint viscosity
† Whether the system is circulating or
non-circulating
† Whether the paint system is heated
or not
† Hours of use, etc.
schedules based on the observed requirements.
Normally, the system should be flushed at least
once each day or per an eight-hour shift. (See
the paint supplier for recommendations regarding
catalyzed paints).
6. Wipe the gun, cable, and the hose with a rag
and suitable mild solvent for the coating being
sprayed.

COLOR CHANGE

If the gun is to be flushed with solvent between
colors (as when switching between two incom-
patible colors or paints), turn ALL electrical power
OFF and carefully follow the gun cleaning and
color change procedures as outlined in the fol-
lowing steps.
!
† BEFORE attempting any cleaning or
color change procedures, the high volt-
age and the AC power to the power sup-
ply MUST be turned OFF!
1. Turn the gun motor to the "OFF" position by
moving the "ON - OFF" to "OFF" position (Ref.
Figure 11). Release the paint pressure at the
pressure regulator and mount the gun on its stand.
† If your equipment has an individual pres-
surized container and hose for each paint
and solvent, or individual hoses for use with
a pump, disconnect the gun.
† When one pressure pot and a single
hose is used, replace the paint container
with a solvent container.
† If the hose is used with a pump, remove
the pump pick-up tube from the paint and
place it in a solvent-filled container.
2. Regulate the pressure to normal operating
setting (or high for faster cleaning) and use one
or two quarts of any suitable cleaning solvent that
is compatible with the paint being used.
3. Remove the gun from its stand and be sure
that the electric power is turned OFF. Position
the feed tube and the contact brush upward
