Vector R Series Cascade Applicators - 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 material 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 materials.
NOTE
2. Trigger the applicator (high voltage ON).
3. Slowly approach the applicator electrode to
any grounded object and make contact.
4. Monitor the current output reading on the
control unit microamp meter as the applicator
approaches ground:
Upon ground contact, the microamp meter should
display 100 µA (for R90) or 90 µA (for R70) and
the green, yellow, and red LED's of the bar graph
meter will all be illuminated.
† 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.

Test Reading
If the reading is outside of the acceptable range
(95-100 µA for R90; 85-90 µA for R70), DO NOT
use the applicator until the problem has been
corrected (see "Troubleshooting Guide" in the
"Maintenance" section.)
5. Release the trigger (high voltage OFF) and
turn the control unit power OFF.
Shutdown (or at end of each shift)
1. Turn the power supply power OFF.
2. Turn the paint supply OFF.
3. Turn the atomizing and fan air OFF.
4. Wipe the applicator, cable, and hoses with a
rag and a suitable cleaning solvent.
5. Flush the lines and allow the solvent to remain
in the lines unpressured (see "Flushing Proce-du-
res" in the "Maintenance" section).
Weekly
• Check the entire system for damage, leaks,
and paint accumulation.
• Clean the atomizer assembly.
