NOTE
CAUTION
!
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 settling
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.
If the coating material is fast settling and the fluid
lines are not flushed soon enough, the internal pas-
sages may become clogged. This can lead to exces-
sive downtime for repair.
Figure 16: Control Unit Meter Current Output 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.
5. Flush the lines and allow the solvent to remain in the
lines unpressured (see "Flushing Proce-dures" in the
"Maintenance" section).
Weekly
• Check the entire system for damage, leaks, and paint
accumulation.
• Clean the atomizer assembly.
APPLICATOR ASSEMBLY
CLEANING PROCEDURE
Routine Cleaning Equipment Needed
• An appropriate solvent
• A solvent safety container (grounded)
• A small soft-bristled brush
• The Ransburg special multi-purpose wrench (19749-00)
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.
CAUTION
!
To avoid damage to the fluid nozzle or needle/
electrode, the paint pressure
MUST
be released by
triggering the applicator prior to removing the tip.
The applicator barrel
MUST
be tilted front
down to remove the fluid nozzle. Failure to do so
may allow paint to enter the air passages, thereby
reducing airflow and damaging the applicator barrel/
cascade. Applicators may be flushed in lieu of tilting.
However, they must be either flushed or tilted down
during nozzle removal!
The control unit power
MUST
be off when
removing the nozzles and/or during any applicator
maintenance.
