TEST IN WATER
Check that all the MP and HP plugs are in place and that a
correctly adjusted second stage is connected to the first
stage. Slowly open the cylinder valve to put the regulator
under pressure.
Immerse the first stage completely in water to check that
there are no leaks.
Note: Do not mistake any bubbles which
are trapped in the regulator with a leak. If
there is a leak there will be a constant
stream of bubbles.
When you are sure that there is no leak, close the cylinder
valve and purge the regulator. Remove the first stage from
the cylinder and refit the dust cap.
If a leak has been detected then note its source and refer to
Table 1. Troubleshooting Guide.
