SECTION 3 INSTALLATION
Never stand directly in front of or behind the regulator
when opening the cylinder valve. Always stand to one
side.
H. Open the cylinder valve SLOWLY a fraction of a turn. This
will prevent damage to the gauge and critical components
in the regulator. When the gauge needle stops moving,
then open the cylinder valve fully.
I. Using a leak test solution, such as P/N 998771 (8 oz. ctr)
or soapy water, test for leakage around the cylinder valve
stem, the regulator inlet connection, and the hose con-
nections at the regulator. Correct any leaks before starting
work.
3.8.1 TO REGULATE FLOW
Flow is controlled by adjusting the owmeter valve until de-
sired ow is indicated by the ball oat in the owmeter tube.
Always take the reading across the TOP of the ball.
