air pressure to the applicator.
4. Toggle on the “Paint Trigger” switch; air
should be escaping from the feed tube. Turn off
the “Paint Trigger”.
5. Toggle on the “Dump” switch; air should be
escaping from the Dump port of the applicator.

Static Decay/Water Pressure Test
The purpose of this section of the test is to verify
that each of the valves in the applicator will pass
fluid. Also, this test verifies all seals along the
fluid passages have been properly installed to
prevent any leakage.
1. Ensure all toggle switches are set to the “off”
or “down” position.
2. Position the applicator where any water
sprayed out of the bell may be collected and
properly disposed of.
3. Verify there is no residual pressure in the
pressure pot included with the test stand. Turn
the regulator dial on the pressure pot counter-
clockwise until all pressure is released. Pull the
bleed-off valve to release any remaining pressure.
4. Loosen the pressure pot clamps until the lid
may be removed from the pot. Fill the pressure
pot with de-ionized or distilled water.
5. Close the lid, tighten the lid clamps so that the
lid is secure and no air pressure may escape.
6. Turn the Fluid switch to “Water” position.
7. Turn the “Fluid Air” regulator to the pressure
pot to 80 psi. Make sure you have distilled water
in the pot.
8. Make sure the dump line is secured in the buck-
et and the dump valve is in the “Open” position.
9. Turn on “Paint In” and “Solvent In” in the Fluid
Enable section.
10. Activate the “Dump” trigger until the air is
completely purged from the manifold. You will
see water running from the Dump output. Turn
the Dump switch off which will stop the water flow.
Turn “Fluid” switch to “Off”. Leak gauge should
stay at pressure.
11. Observe the applicator for any possible water
leakage, wait 3 minutes. No seepage is allowed.
12. If leak is found, turn the “Fluid” switch to “Air”
and activate the dump until all water is evacuated.
Turn “Fluid” switch to “off”. Repair leak and repeat
the test.
