CAUTION:
The dial pressure gauge should read “0 PSI / BAR” when the
handwheel is in the closed position and the system is depressurized. DO
NOT attempt to use the EBIS if the gauge indicates pressure until it has
received inspection and service from a factory trained service technician.
CAUTION:
DO NOT attempt to pressurize the EBIS without first checking
to ensure all components are securely fastened to the first stage, second
stage and inflator mechanism.
6.
Open the handwheel to pressurize the system. Closely examine the dial
pressure gauge to ensure the cylinder is filled to its maximum capacity as
marked
(Fig. 24)

NOTE: The operational range for a carbon fiber composite cylinder unit is
3000 - 4500 PSI (207 - 310 BAR) or in the “GREEN ZONE”. A 13 in³ (63.4
L) carbon fiber composite cylinder is equivalent to a 1.5 ft³ (42.5 L) aluminum
cylinder when both are filled to 3000 PSI (207 BAR). A 17.5 ft³ (85.5 L) carbon
fiber composite cylinder is equivalent to a 2.0 ft³ (56.6 L) aluminum cylinder
when both are filled to 3000 PSI (207 BAR). Aqua Lung classifies carbon fiber
composite cylinders by floodable volume (cubic inch) and aluminum cylinders
by expanded volume (cubic feet). Values in liters are metric expanded capacity.
