TROUBLESHOOTING
47
Problem: Nitrogen regulator leaks
Probable Causes:
1. Quick-connect from nitrogen regulator assembly not fully engaged.
2. O-ring defective in quick-connect fitting.
3. Nitrogen hose fittings not firmly tightened and secured.
4. Nitrogen regulator assembly not fully engaged into nitrogen bottle.
Corrective Actions:
1. Firmly secure all quick-connect fittings at the end of the hose assembly.
2. Replace O-ring in quick-connect fitting.
3. Firmly tighten all hoses and fittings on nitrogen regulator assembly.
4. Firmly secure nitrogen regulator assembly to nitrogen bottle.
Problem: Chemical cylinder leaks.
Probable Causes:
1. Ball valve open.
2. Stratoflex remains partially open when chemical lines are disconnected.
Corrective Actions:
1. Close ball valve.
2. When disconnecting chemical or transfer lines, make sure that the flow of chemical around the swivel
nut has stopped before fully disengaging filter assembly. Make sure that the cavity surrounding the
pocket in the cylinder Stratoflex is clean and free. This can then be treated with a light lubricating
oil to keep it from further sticking.
3. Replace O-ring in Strat.
FOAM CHARACTERISTICS
Problem: Foam is rubbery or spongy to the feel after curing.
(System is off ratio. B-SIDE high in proportion to the A-SIDE)
Probable causes:
1. Flow restricted on A-SIDE line or cylinders.
2. Poor mix.
3. Too much B-SIDE flow.
Corrective actions:
1. A-SIDE restricted flow has many causes.
a) Ball valves closed on the A-SIDE. Check that all A-SIDE ball valves on gun and tanks are open.
b) Temperatures too cold on the A-SIDE. Bring chemicals up to correct operating temperatures after
reducing nitrogen pressure to 150 PSI.
c) Low pressure on the A-SIDE chemical cylinder. Adjust to correct operating pressure range.
d) High pressure on B-SIDE chemical cylinder. Adjust to correct operating pressure range.
