Charging SCUBA Cylinders.
Figure 2-12. Charging SCUBA Cylinders.
(1) Position SCUBA cylinder(s) (1) to be charged in trough (2).
(2) Remove dust caps from fill stations #1 through #4 at the control panel and connect fill hose(s) and
strain reliefs to stations as needed.
(3) Connect fill hose(s) and strain reliefs to SCUBA cylinder(s) (1).
(4) Ensure bleed screw (3) on each yoke adaptor is closed.
(5) Ensure reserve valve (4) on each SCUBA cylinder is in the down position.
(6) Fully open the ON/OFF valve (5) on each of SCUBA cylinder then back off on valve 1/4 turn.
NOTE
To efficiently utilize the air within each storage cylinder, a cascading mode of
operation is optimal. This allows air from the cylinder with the lowest pressure
reading to be used first.
(7) Slowly open 1/4-turn ball valve (6) for storage cylinder with the lowest pressure reading.
(8) Slowly open manifold valve (7).
