se c t i o n

External Inspection

1.Closely examine the conical filter of the first stage to check for any signs that contaminants have entered the system, including sea water, rust, or aluminum oxide.

NOTE: A green discoloration positively indicates that mois- ture has entered the regulator, and internal corrosion may have occurred. Other types of discoloration may indicate that the regulator has been used with a corroded cylinder. Advise the customer of this, and the possible need to obtain service for their cylinder.

2.Slide back the hose protector(s) to inspect the condition of the LP hose at its fittings and along its length. Check closely for any signs of blistering or abrasion, or corrosion of the fittings.

3.Inspect the condition of the mouthpiece to check for torn bite tabs, holes, or deterioration.

Immersion / Leak Test

1.Check to ensure that the regulator is fully assembled and connected to a first stage, and that there are no open ports or hoses. Connect the first stage to a cylinder that is filled with 3,000 psi, and open the cylinder valve to pressurize the regulator.

2.If leakage cannot be heard, or if the source of leakage detected audibly is not obvious, immerse the second stage in fresh water to check further for any signs of air leakage through the mouthpiece and at the hose fitting.

3.Note the source of any leakage found and refer to Table 2 - Troubleshooting to determine its possible cause.

4.Close the cylinder valve and depress the second stage purge cover to depressurize the regulator.

After completing the Preliminary Inspection, proceed to
