XS Scuba Inspire Regulator Service Manual
C. With the regulator under pressure, cycle the
system several times by repeatedly pressing the
2nd stage purge.
D. Check the medium pressure on the gauge.
With an inlet pressure of 3000 psi (207 bar), it
should be between 130-145 psi (9-10 bar).
E. If the MP is low, insert a 6 mm hex key into the
adjusting screw. Turn the adjusting screw CW.
As you do this keep purging the 2nd stage with
every quarter turn. You should observe the MP
increasing.
F. Likewise, if the MP is too low, insert a 6
mm hex key into the adjusting screw. Turn the
adjusting screw CCW. As you do this keep
purging the 2nd stage with every quarter turn.
You should observe the MP decreasing.
NOTE: This image shows an alternate way
to measure the intermediate pressure. It shows
an AC380 IP Gauge Checker threaded directly
into a MP port.
G. Let the unit sit under pressure for 5 minutes.
The medium pressure should remain fairly stable.
It is common to see the pressure creep by a few
psi. The standard of acceptability for medium
pressure creep is up to 5 psi over a 5-minute
period. If the medium pressure creeps more than
5 psi over a 5-minute period, this indicates that
there is a leak. Refer to the Troubleshooting Table
located in the back of this manual.
2. Immersion Test
A. Remove the Inline Adjusting Tool or other MP
gauge.
B. Attach a properly functioning second stage.
C. Attach to a full cylinder and pressurize
D. Submerge the entire first stage into clean, fresh
water.
E. Observe at least one minute for bubbles.
i. Bubbles would indicate that there is a
leak. This would require partial disassembly
and troubleshooting to correct the problem.
NOTE: Do not confuse bubbles from trapped
air in the main spring chamber with bubbles from a
leak. If there is leak, the bubbles will come out in a
constant stream.
This concludes the servicing of the Inspire First
Stage.
