EXTERNAL LEAK TEST

After disconnecting the regulator from the flow bench, connect it to a scuba cylinder filled to approxi-

mately 3,000 psi. Open the cylinder valve to repressurize the regulator, and submerge the entire

system in a test tank of clean water.

Observe any bubbles arising from the submerged regulator over a one minute period. The recom-

mended time is necessary due to slower bubble formation that occurs in smaller leaks. Bubbles indi-

cate a leak, which requires that the system must be disassembled at the source to check sealing sur-

faces, assembly sequence and component positioning in order to correct the problem(s).

NOTE: Extremely small leaks may be better detected by applying a soap solution or Snoop™ to the

leak area. Bubble streams will indicate the source of the leak. Before disassembling to correct any

leaks, rinse the entire regulator thoroughly with fresh water and blow out all residual moisture with

filtered, low-pressure (50 psi) air. Disassemble and remedy the problem, referring to " Table 1 -

Troubleshooting ."

Depress the purge cover fully to ensure that an adequate volume of air needed to clear the second stage

flows through the mouthpiece. Then, inhale slowly but deeply from the mouthpiece. A properly ser-

viced and adjusted regulator should deliver air upon deep inhalation without excessive inhalation

effort, freeflow, or "fluttering" of the second-stage diaphragm. When exhaling, there should be no

fluttering or sticking of the exhalation valve. If any of these problems occur, refer to Table 1 -

Troubleshooting.

This concludes annual service procedures for the Glacia Second Stage Regulator.
