Cressi-sub B.C.’S JACKETS Manual De Instrucciones página 17

A correct design is the starting point to reach the best
results.
After many tests and researches, CRESSI-SUB has
created a modern back-piece assuring a vertical
adjustment of the back support in order to fit each waist.
The newly designed handle makes it easier to carry the
jacket everywhere.
You can also buy an additional strap to fasten the tank or
it is possible to fasten the tank in two different positions.
INFLATOR
It is the heart of every jacket and assures inflation and
deflation.
This important component consists of the by-pass, the
ID hose and the deflation valve.
Designed according to the latest technologies, it has a
more elegant and discreet look, matching the other
BC parts.
A detailed description of the characteristics of
each component is given below.
BY-PASS
It controls inflation and deflation.
This very difficult mechanical function has been made
easy by CRESSI-SUB technicians through the use of
modern materials.
The following figures show the maintenance work which,
for safety reasons, must only be carried out by technical
personnel authorized by CRESSI-SUB (see figure pag. 16).
CRESSI-SUB ASSUMES NO RESPONSIBILITY
FOR ANY MAINTENANCE WORK CARRIED OUT
TO THE BY-PASS BODY BY PERSONNEL NOT
AUTHORIZED BY CRESSI-SUB.
The low pressure hose of the first stage is connected to
the by-pass by means of a quick connector.
Inflation is controlled by push-button 1 (Fig. 1), with air
coming from the hose of the first stage, or by blowing in
the mouth piece.
Deflation is controlled by push-button 2 (Fig. 2) located in
the lower part of the by-pass.
The form of the CRESSI-SUB by-pass has been
designed to assure a safe and correct fastening and all
comfortable conditions during the dive.
QUICK DEFLATION VALVE
The new deflation valve of the CRESSI-SUB inflators has
two main functions:
1) It assures a complete and quick deflation by pulling the
internal cord of the ID hose (Fig. 4).
2) It also operates as additional overpressure valve, an
exclusive accessory against overinflation, assuring the
highest safety during the jacket inflation (Fig. 3).
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
