TROUBLESHOOTING GUIDE
General Problem Possible Cause Corrective Action
Fluid does not turn on 1. Insufficient trigger pilot air.
2. Trigger air tube possibly left disconnect-
ed.
3. Trigger air tube is pinched or broken
4. Piston seal within applicator spray head is
not in place or there is an extremely tight
fit between the seal and the cylinder wall.
5. Piston u-cup is bad.
1. Increase to 70 psi minimum.
2. Reconnect tubing
3. Check tubing for kinks or damage.
4. Make sure that the seal is in the proper
position and / or lubricate with a small
amount of petroleum jelly.
5. Replace if damaged (trigger air will leak
out of rear cap).
No fluid flow 1. Clogged fluid nozzle.
2. Plugged fluid inlet.
3. No trigger pilot air.
1. Remove, inspect and clean fluid nozzle.
2. Flush clean.
3. Check trigger air pilot (70 psi min.)
Continuous fluid flow 1. Trigger pilot air is not shutting off.
2. Weak or damaged needle spring.
3. Fluid seal is worn or damaged.
1. Remove trigger pilot air.
2. Replace needle spring.
3. Replace fluid seal.
Lack of fan air control 1. Improperly torqued seal retainer.
2. PTFE o-ring on bushing is damaged.
3. O-ring on bushing is damaged.
1. Torque to 30-35 lbs.-in.
2. Replace PTFE o-ring (this shuts off the
fan air).
3. Replace o-ring (keeps fan and atomiza-
tion air separated).
Low or no high voltage 1. High current draw.
2. Loss of high voltage connection between
power supply and manifold.
3. Contact spring damaged.
4. Conductive sponge damaged / removed.
5. Applicator grounding out.
6. Power supply is damaged (refer to specif-
ic power supply manual for troubleshoot-
ing).
1. Paint resistivity must be > 0.1 M Ohms.
2. Check HV cable connection to manifold.
Apply dielectric grease to cable end and
reconnect.
3. Replace contact spring.
4. Replace conductive sponge.
5. Clean atomizer externally with non-polar
solvent., check for internal fluid leaks or
internal arcing.
