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.
