3. Thread the end cap (9) onto the dry chamber until
handtight. Using an in/lbs torque wrench and an 8mm hex
key adapter, tighten the end cap to 35 in/lbs. Recheck the
MP to make sure it is still at 137 psi (standard) or 13 psi
(supreme).
4. Close the cylinder valve and depressurize the regulator.
Remove the test gauge and reinstall the port plug(s).
This Ends Reassembly
FINAL TESTING
Immersion Test
1. With the port plugs and at least one properly adjusted
second stage installed, slowly open the cylinder valve and
pressurize the first stage. Completely submerge the first
stage in fresh water and check for leaks.
NOTE:
Do not confuse bubbles from trapped air
with a true leak. If there is an air leak, bubbles will
come out in a constant sream.
If a leak is detected, note the source of the leak and refer to
Table 1:Troubleshooting Guide, p.11 for possible causes
and corrective actions.
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, LP (30 psi) air.
Disassemble and remedy the problem by
referring to Table 1: Troubleshooting Guide, p. 11.
Subjective Breathing Test
1. Depress the second stage purge to ensure that the
volume of airflow is adequate to clear the second stage.
. Breathe deeply from the mouthpiece. A properly serviced
and adjusted regulator should deliver a smooth, uninterrupted
airflow upon deep inhalation; without excessive effort,
hesitation, or freeflow. If any abnormalities or problems occur,
refer to Table 1: Troubleshooting Guide, p. 11.
When completed, close the cylinder valve and depressur-
ize the regulator. Remove the first stage from the valve and
secure the dust cap in place.
This concludes the service
procedures for the Legend First Stage
