TROUBLESHOOTING
46
Problem: Erratic Chemical Flow
Probable Causes:
1. Chemical temperature too cold.
2. Chemical temperature too cold in chemical lines due to low ambient temperature or damaged
insulation on chemical lines.
3. Low operating pressure.
4. Incorrect nitrogen hook up.
5. Partial restriction in controller orifice.
6. Stratoflex fittings not properly connected.
7. Partially plugged filter. Call FSI Application Specialist before correcting.
Corrective Actions:
1. Inspect temperature gauge. If temperature is below operating pressure, depressurize cylinders, bring to
operating temperature and re-pressurize.
2. Run approx. 6–8 lbs. of chemical through gun in order to obtain warm chemical from cylinders.
3. Examine nitrogen regulator to make sure that sufficient quantities are present to give the minimum of
continual 240–245 p.s.i. Replace nitrogen source if needed.
4. Examine quick connects from the nitrogen lines connected to the nitrogen cylinder to make sure that they
are properly secured and are connected to the in-put nitrogen fitting.
5. Remove flow controller and inspect for contamination. Replace or clean as required.
6. Disconnect Stratoflex fitting. Make sure grease and debris is cleaned out of fitting. Reconnect and make
sure Strat is tightened all the way down.
7. Remove, clean, inspect and replace filters on Strat assemblies. Call FSI Technical Service Dept. before
correcting.
