Cressi-sub B.C.’S JACKETS Manual De Instrucciones página 72

MOUTH-INFLATION TUBE
This is a silicone tube equipped with a non-return valve
and located inside the right pocket of the jacket.
OVERPRESSURE VALVE
All CRESSI-SUB jackets are equipped with this valve
located in both the lower and upper right part of the
jacket, on its rear side. Besides controlling inflation by
checking that the maximum interstage pressure is not
exceeded, this valve allows the diver to manually deflate
when his/her position mainly concentrates air in the lower
part of the jacket.
To operate the lower right valve, just pull the cord, by
grasping the special knob which, depending on the
jacket model, is located on the rear side in the lower right
part or on the front side in the lower right part.
To operate the upper right valve, just pull the cord, by
grasping the special knob located on the front side on
the right shoulder-strap.
USE OF THE BCD - JACKET ASSEMBLY WITH
STRAPS
First, you must fasten the jacket to the tank, as shown on
the figure (steps 1 and 2), correctly putting the buckle
in the strap.
WARNING - YOU MUST ALWAYS FASTEN THE
STRAP WET!
Otherwise, if the strap is dry, it could stretch, when
submersed, and the tank could slip out.
When fastening the jacket to the tank is Important to get
the upper side of the back-piece 2-4 cm under the tank
deflation valves so that the diver's head doesn't
bump against the regulator, hindering his/her
swimming.
Secondly, you must connect the LP hose to the by-pass,
joining it to the first stage low pressure port because the
BC has been designed to be used with an air pressure
ranging from 6 to 12 bars, consequently a higher
pressure would be dangerous for the diver.
The other port of the LP hose is provided with a quick
connector: make sure that there is not any dirt, sand or
other substances before connecting it to the by-pass.
