Flushing Procedures; Applicator Assembly Cleaning Procedure - Ransburg Vector AA90 Cascade Service Manual

FLUSHING
PROCEDURES
The fluid system should be thoroughly cleaned by
flushing with a clean compatible solvent whenever
a color change is made, or when the applicator
will not be used for an extended period.
1. Turn OFF the control unit/power supply power.
2. Turn the paint supply OFF.
3. Turn the shaping air supply OFF. Bleed all air
from the line.
4. Tilt the applicator down and trigger until it is
clear of paint.
5. Set the trigger stop lever and remove the nozzle
nut, air nozzle, and fluid nozzle.
6. Connect the solvent supply.
7. Release the trigger stop and run solvent through
the system until it runs clear.
8. Disconnect the solvent supply.
9. Trigger the applicator until it is clear of sol-
vent. After the preceding steps are complete, the
applicator is ready for color change, storage, or
maintenance.
† If production downtime is to be short,
the fluid lines may not require flushing
(depending on the coating material being
used). If the solids in the coating settle
slowly, the lines will not need to be flushed
as soon after shutdown as with fast set-
tling solids. The paint being used and the
length of downtime will determine the need
for flushing. Metallic paint and primer will
require flushing sooner than other types of
coating material.

† If the coating material is fast settling
and the fluid lines are not flushed soon
enough, the internal passages may be-
come clogged. This can lead to excessive
downtime for repair.
Weekly
• Check the entire system for damage, leaks,
and paint accumulation.
• Clean the atomizer assembly.

Routine Cleaning
Equipment Needed
• An appropriate solvent
• Solvent safety container (grounded)
• Small soft-bristled brush
For efficient electrostatic operation, keep the ap-
plicator's exterior and low voltage / high voltage
cable free of paint accumulation. This prevents
the loss of voltage to ground with a resultant re-
duction in transfer efficiency.

!
† Before cleaning the nozzle assembly,
turn the control unit or power supply OFF
and flush the fluid line with a compatible
solvent until clean. Turn the paint and air
supplies OFF. Trigger the applicator to re-
lieve both fluid and air pressures.
