WARNING!
For your safety, and the safety of others:
• Always test with oil-free air or dry nitrogen only.
• Always wear eye protection while testing a Regulator.
• Always perform all of the following test procedures after reassembling a Regulator.
1. Adjust the Test Manifold to the proper pressure shown in TABLE 4.

2. Attach the Regulator to the Manifold connection or test adapter. Start the nut by hand
(do not force), and tighten securely with a wrench to create a seal.
3. Turn the Regulator Adjusting Knob clockwise two or three times until you feel slight
tension being applied to the Adjusting Spring.
4. Slowly open and close the Manifold Valve two or three times to remove contamination
that may cause malfunctions. Leave the Manifold Valve closed.
a. If no flow comes through the Regulator, determine the cause – refer to the
TROUBLESHOOTING CHART at the end of this section.
5. Turn the Adjusting Knob counterclockwise until it stops, and attach the Test Gun (with a
#52 restricting orifice) to the outlet of the Regulator.
6. Open the Test Manifold Valve and close the Test Gun.
a. Manifold working pressure will appear on the High Pressure Gauge.
b. If the Low Pressure Gauge begins to show pressure building, turn the Test Manifold
off and refer to the TROUBLESHOOTING CHART.
7. Use the values in the following TABLE 5 for all subsequent tests:
