CRESSI-SUB JACKETS WITH ID

HOSE Congratulations on your choice! This product, which is the result of continuous research and development, is made in compliance with CRESSI-SUB quality standard, thus ensuring pleasant and absolutely safe diving. GENERAL WARNINGS You must be trained in buoyancy compensation from a qualified diving instructor before using this product. The use of the device by people without qualification is very dangerous and can cause serious injury or death. CRESSI-SUB recommends to read this manual before using the jacket. A recognized diving qualification is always required. INTRODUCTION The CRESSI-SUB jackets are certified to reach a depth of 50 mt, as prescribed in the CE standard, having passed the required tests. These devices are very important to dive with air regulator and tanks because they provide buoyancy control by inflating or deflating, thus changing the diver's buoyancy. For this reason, they are also called BCDs, that is Buoyancy Compensating Devices. Their rapid development has known a range of very different models, and they have nowadays taken the form of a life jacket, very easy to put on. WARNING! THIS IS NOT A LIFEJACKET AND DOESN'T ASSURE AT THE SURFACE A HEAD UP POSITION. COMPONENTS All CRESSI-SUB jackets have been designed to assure a perfect fit and comfort in most situations. The use of high quality and strong materials, such as the famous "CORDURA 1000", the high-frequency weldings and the double seams made from nylon thread assure the longest duration of the product. Some weldings are located in a strategic position in order to control inflation and deflation in order to assure the best buoyancy. The very comfortable and functional newly designed pockets allow to house such accessories as cameras, etc. All jackets are equipped with special lateral weight-holding pockets which, in case of emergency, allow to quickly eject weights. Depending on models, either gravity systems (automatic ejection of the weight after manual release of the safety buckle) or C-Trim systems (manual ejection of the special weight-holding bag) are used. The special design of the jacket allows to rationally arrange all diving instruments (octopus, gauge, torches, compass...) through many buckles and springclips, making the dive easier. BACK-PIECE Its most important function is to provide a correct connection between the tank and the BCD, and then between BCD and diver. Libretto 25/10/05 25-10-2005 12:53 Pagina 1516 English 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).

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 Libretto 25/10/05 25-10-2005 12:53 Pagina 1617English 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. Libretto 25/10/05 25-10-2005 12:53 Pagina 1718 English Libretto 25/10/05 25-10-2005 12:53 Pagina 1819English 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.

HOW TO WEAR THE JACKET

You can wear the jacket either out of the water or in the water. It is absolutely necessary to learn how to correctly wear the tanks and the jacket during the diving course. The jacket is fastened to the diver's body with shoulder straps and a cummerbund. The main fastening is assured by a cummerbund with abdominal strip and Freematic system that fits every waist and provides the best fastening and a rapid adjustment of the jacket to the body without compression on the chest and the waist. An additional adjustment is provided by the adjustable shoulder-straps with large front quick-release buckles; the tank is fixed to the back-piece by means of an adjustable band, so that it is possible to adjust tanks of different diameters. Now, once you have rapidly checked for the correct operation of the inflator, the hoses and the accessories, you are ready to dive. OPERATION The jacket operation is controlled by the by-pass, the deflation valve and the overpressure valves. To begin a dive, you must deflate the inflated jacket Libretto 25/10/05 25-10-2005 12:53 Pagina 1920 English by pulling the ID hose (Fig. A), then using the deflation valve or the lower overpressure valve, if you descend head down. Now, you can descend at a descending rate that increases in proportion to the water pressure compressing you. To descend slowly you can inflate. By shortly lightly pressing the inflation button, you can modify the descent rate and then progressively adjust yourself to the increasing depth. During the dive you can compensate buoyancy in accordance 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.

USE OF THE EQUIPMENT AND RISK

EVALUATIONS Before using a diving equipment you must follow a recognized diving course and obtain a qualification. You must be trained and in a good state of health. Before every dive you must accurately consider the environmental conditions and the psychophysical state of the diver. It is recommended to avoid the dive, when even only one of the above conditions becomes dangerous. The environmental dangerous conditions can be the sea situation, the sea currents, the low water temperature, the poor visibility. The physical dangerous conditions can be a bad state of health, an emotional or physical stress situation, a lacking training, tiredness, digestion. The materials and the design of CRESSI-SUB equipment assure a totally safe use. Libretto 25/10/05 25-10-2005 12:53 Pagina 2021English

CARE AND MAINTENANCE

After each use, carry out the following operations:

• Remove the tank and rinse the jacket with fresh water, both outside and inside, allowing water to enter the ID hose and the bag through the deflation or the over- pressure valve.

• Drain any water left in the jacket and allow it to dry in the open air with open valves.

• Once it is completely dry, close all valves, lightly inflate it (using the mouth-inflation piece located in the by-pass) and store it in a cool and dry place. If the device is not used for a long time, lubricate the hose connection and the collar with silicone grease and spread the ID hose with talcum powder. The CRESSI-SUB jackets are in conformity with the EN 250 - EN 1809 standards and have been given the CE safety certification (CE 0474). A label bearing the following information is sewn under the lateral or rear pocket: WARNING! THIS IS NOT A LIFE JACKET AND DOES NOT ASSURE THE DIVER OF KEEPING HIS/HER HEAD OUT OF THE WATER -To use this jacket, a specific course held by a certified instructor must be attended. - In case of emergency, face up buoyancy at the surface may not be provided to all users and in all conditions. - Before use, check for good condition and proper operation of the jacket and make sure that no holes o damages are present. - Follow all the instructions in the Owner's Manual. - Do not inhale gases from inside the bag. - Do not remove from the jacket.

FLIGHT CONTROL SYSTEM INFLATOR

Its largely known functions are to inflate or deflate, but differently from the traditional inflator with ID hose, the new Flight Control System consists of two new elements (by-pass and deflation valve) and provides the following great advantages:

• A fixed by-pass position designed in such a way that controls are always visible and can be easily reached by the hand (even when wearing gloves) thus enabling to control buoyancy in any driver's position.

• The inflation and deflation controls are associated to different mechanical movements for higher safety.

• The by-pass shape provides an ergonomic handgrip and allows to operate controls always with the same hand without moving it (you just have to move only some fingers); moreover, the special soft pipe (connection between bag and by-pass) allows the hand to move more freely. A detailed description of the characteristics of each component is given below. BY-PASS Its function is to control bag inflation or deflation. It is located in the lateral left part of the jacket and the pocket is shaped in such a way not to hinder the hand movements during use. The by-pass quick connection is located in order to facilitate connection/disconnection of the low pressure hose coming from the first stage. The inflation function is carried out by pressing a push-button (Fig. 1) allowing air to enter the bag. The deflation function is carried out by moving a slider forward, (Fig. 2) allowing air to escape from the bag, in this way you can have a gradual deflation or a quick deflation by immediately taking the slider to the end of its stroke.

1. Place the jacket on a flat surface in its operating

position, as shown on Fig. 10 (with the band and all buckles closed).

2. Keep the deflation slider at the end of its stroke, while

performing adjustment by means of a 5 mm hexagonal wrench, as shown on Fig. 11.

3. Adjustment is correct when the cam (see a on Fig. 12)

is placed at approximately a distance R which corresponds to 3 mm from the bushing (see b on Fig. 12), keeping the deflation slider at the end of its stroke, as shown on Fig. 11.

4. Finally, put the safety lock nut in order to fix adjustment

using the 5 mm tee hexagonal wrench to keep the deflation spindle in place (in order not to lose the obtained adjustment), and the modified 13 mm tubular wrench (supplied by CRESSI-SUB) to screw the safety lock nut, as shown on Fig. 13.

QUICK DEFLATION VALVE

The new valve allows greater deflation than the one traditionally used in the inflator with ID hose. Its primary function is to allow gradual or quick bag deflation: in fact, the valve, equipped with servomechanism, is operated through a cable directly by the by-pass slider. Its secondary function is to act as an additional overpressure valve, by checking that the bag is not excessively inflated and does not exceed the maximum interstage pressure. The following figures show the O-ring replacement which, for safety reasons, must only be carried out by technical personnel authorized by CRESSI-SUB.

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.

HOW TO WEAR THE JACKET

You can wear the jacket either out of the water or in the water. It is absolutely necessary to learn how to correctly wear the tanks and the jacket during the diving course. The jacket is fastened to the diver's body with shoulder straps and a cummerbund. The main fastening is assured by a cummerbund with abdominal strip and Freematic system that fits every waist and provides the best fastening and a rapid adjustment of the jacket to the body without compression on the chest and the waist. An additional adjustment is provided by the adjustable shoulder-straps with large front quick-release buckles; the tank is fixed to the back-piece by means of an adjustable band, so that it is possible to adjust tanks of different diameters. Now, once you have rapidly checked for the correct operation of the inflator, the hoses and the accessories, you are ready to dive. To check for correct inflator operation, before each diving, it is recommended to operate the by-pass controls several times, trying to press the inflation push-button and, in particular, to move the deflation slider. OPERATION The jacket operation is controlled by the by-pass, the deflation valve and the overpressure valves. To begin a dive, you must deflate the inflated jacket by either moving the slider controlling the deflation valve or operating the overpressure valve. As previously said, you can have a gradual deflation by moving the slider across its stroke or a quick deflation by immediately taking the slider to the end of its stroke (Fig. 14). Now, you can descend at a descending rate that increases in proportion to the water pressure compressing you. To descend slowly you can inflate. By lightly pressing the inflation button, you can modify the descent rate and then progressively adjust yourself to the increasing depth (Fig. 14). Inflation push-button Deflation slider Fig. 14 Libretto 25/10/05 25-10-2005 12:53 Pagina 7273English 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.

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). Fig. 15 Fig. 16 Libretto 25/10/05 25-10-2005 12:53 Pagina 7374 English
