During the dive you can compensate buoyancy in accor-
dance with the depth and tank lightening, due to the air
consumption.
To ascend you must inflate, so that a lightly positive
buoyancy can be obtained.
In this case, the ascending rate increases in accordance
with the pressure and you must operate the deflation
systems to compensate and avoid a too rapid ascent.
WARNING: IT IS EXTREMELY DANGEROUS FOR
THE DIVER TO ASCEND TOO FAST.
AVOID OVER INFLATING THE JACKET, AND
ASCEND WITH A NEUTRAL BUOYANCY, CON-
TINUOUSLY ADJUSTING BUOYANCY.
In case of automatic delivery, it is possible to rapidly
disconnect the hose by acting on the by-pass quick
connector (Fig. 15), thus stopping air from flowing into the
bag.
IMPORTANT:
The deflation rate is always greater than the inflation rate:
consequently, in an emergency with a continuous air
flow, in order to avoid a sudden bag inflation,
you can
operate one of the three deflation valves in the
jacket, in the event you are not able to readily disconnect
the hose.
To let air into the bag, use the appropriate mouth-inflation
tube located in the right pocket (Fig. 16).
