VALVES

To allow the air to escape from the bladder, each Cressi BCD has a control

unit with two valves, as laid out above. The Aquawing and Aquawing +

models are equipped with an additional quick dump valve and pressure relief

valve located on the inside in the lower left. The diver can therefore enjoy

complete safety should they encounter emergency circumstances during

a dive. This type of valve is operated manually by pulling a knob and must

be easily accessible to allow the diver to empty the pneumatic bladder in

most positions. Furthermore, as mentioned above, it is also a pressure relief

valve, i.e. a valve that releases the air from the bladder when the pressure is

excessive.

LOWER LEFT INTERNAL VALVE:

It is located in the lower left internal area, and the knob that activates it is

located immediately under the valve itself near the edge of the bladder (fig.

55). It is used to release air when the diver is upside down or in a horizontal

position and, if necessary, at the end of the dive, to drain any water that has

entered the bladder.

i WARNING!

When storing weight in these rear pouches, it cannot be

released in an emergency situation, and must be supplemented by a

main weight system. It must also have a low enough weight that the

diver establishes positive buoyancy when they release the main weight

(fig. 56).

PUTTING THE BCD ON:

Using both hands, grasp the ends of the abdominal strap and pull it upwards

and outwards (about 45 degrees) from the body. Then close the two quick

release buckles on the abdomen and the crotch (see the previous chapter,

entitled "Harness Adjustments"). To support the heavy tank, we recommend

placing it on a raised surface with respect to the ground in order to perform

the manoeuvre as comfortably as possible. We do not recommend putting

the BCD on in the water.

EMERGENCY RELEASE:

If you need to get out of the BCD quickly, simply loosen the harness as follows:

open the crotch and abdominal buckles and make sure that the two ends of

the abdominal strap are free; grab the strap on the shoulder straps just above

the waist and move it outwards and upwards from the waist (see the previous

chapter, entitled "Harness Adjustments").
