WARNING: Before using the DSIS / LPIS, it is important to receive in-water training which simulates proper use of this system. You must also understand the basic principles and techniques of buoyancy control both on the surface and underwater. Use of the DSIS / LPIS without proper training is dangerous and can result in serious injury or death.

WARNING: During training exercises, it is important to ensure that the DSIS /LPIS is always pressurized whenever it is submerged in order to prevent the entrance of water into the system. Whenever the system has been completely emptied of air underwater, it is important to return the DSIS /LPIS as soon as possible to a qualified technician for visual inspection and any necessary service before attempting to refill it.

WARNING: It is important to fill the DSIS / LPIS only with dry, filtered air with a water vapor content that does not exceed -65°F / -53ºC dew point. Excess water vapor in the air can cause ice to form inside the DSIS / LPIS and interfere with the operation of the system at colder temperatures.

NOTE: When instructed to “OPEN” the handwheel, turn the handwheel counter-clockwise. The red indicator ring will not be visible in the handwheel window, this indicates the SEA is in the “ON” position.

When instructed to “CLOSE” the handwheel, turn the handwheel clockwise.The red indicator ring will be visible in the handwheel window, this indicates the SEA is in the“OFF” position.

NOTE: When instructed to unscrew or loosen a part, turn the part counter-clockwise.When instructed to screw, or tighten a part, turn the part clockwise until hand tight. DO NOT use any tools to install components.

WARNING: When diving in cold water (below 50˚F or 10˚C), you must have received training and certification in the techniques of cold water diving from a recognized training agency.

NOTE: When instructed to depressurize the system, close the handwheel, and connect the MP hose to an inflation device. Depress the inflator button on the device for 5 seconds and release for 5 seconds. Repeat this procedure until the system is depressurized. Remove MP hose from inflation device when done.

PRE-DIVE INSPECTIONBefore each use, the DSIS / LPIS must be given a thorough visual inspection and functional test by a qualified technician. NEVER use a DSIS / LPIS which shows signs of damage, leakage or substandard performance.

1. Carefully inspect the medium pressure hose to ensure it is securely connected into its respective port on the first stage. Inspect the length of the hose to ensure that it is not blistered, cut or otherwise damaged. Inspect the hose fittings for any signs of corrosion.

2. Visually inspect the entire system for any external damage, such as dents, gouges, cracks or severe external corrosion.

3. Ensure the handwheel is closed and the system is depressurized. Inspect the pressure gauge, checking that it is securely fastened to the first stage. Closely examine the pressure gauge to ensure that it reads “0 PSI (Fig. 16).

Figure 16

“0 PSI”

CAUTION: The pressure gauge should read “0 PSI” when the handwheel is closed and the system is depressurized. DO NOT attempt to use the DSIS / LPIS if the gauge indicates pressure until it has received inspection and service from a qualified technician.

CAUTION: DO NOT attempt to pressurize the DSIS / LPIS without first checking to ensure that the MP hose and pressure gauge are securely fastened to the first stage.

5. Closely examine the pressure gauge to make sure it reads “3000 PSI”, indicating a full cylinder (Fig. 18).

Provided that these pre-dive inspection requirements have all been met, the DSIS / LPIS is now ready for use.

CAUTION: Do not deplete the DSIS / LPIS of air during the pre-dive inspection. Doing so will drop the pressure below the “3000 PSI” and it will have to be topped off by maintenance personnel.

4. Connect the DSIS / LPIS MP inflator hose onto the QD fitting of the inflation device being used. Open the handwheel to pressurize the system (Fig. 17).

6. Briefly depress the inflator button to ensure that sufficient airflow is provided to the MP hose. Immediately after releasing the inflator button, listen closely to ensure that the MP hose does not continue to allow any air flow.

POST-DIVE INSPECTION1. Upon completion of the dive, close the handwheel and completely depressurize the system. Check DSIS / LPIS for signs of damage and contamination. Report discrepancies to maintenance personnel.

CARE AND MAINTENANCEIt is important to provide the proper preventative maintenance in order to ensure the best possible performance and reliability of the DSIS / LPIS. The following maintenance procedures should be performed routinely after each use of the equipment.

1. After each dive, the DSIS / LPIS must be cleaned, inspected and prepared for the next use or storage.

3. After the system has been properly soaked, it is important to thoroughly rinse the first stage, MP hose and QD fitting with a pressurized stream of water. This will remove the salt and mineral deposits that were loosened during soaking.

4. When it has been properly soaked and rinsed, wipe it as dry as possible with a clean towel and gently shake the first stage and MP hose to dislodge any water that has remained inside. If possible, use clean low pressure air to blow any remaining water out of the retainer cap. Reinstall the rubber retainer cover when the unit is dry.

5. Close the handwheel and depressurize the system before storing or transporting.

2. As soon as possible after diving, the DSIS / LPIS should be soaked thoroughly for at least one hour in warm (not over 120ºF / 49ºC) tap water to loosen and dissolve salt (if used in salt water) and mineral deposits. Before soaking, remove the rubber retainer cover (Fig. 18). To prevent the enterance of moisture into the system, open the hand-wheel to pressurize the system. Figure 18

22 DSIS / LPIS User's Manual

WARNING: DO NOT store the DSIS / LPIS partially filled. Doing so may prevent the safety plug assembly from functioning properly in the event of fire or exposure to extreme heat. This may cause the cylinder to rupture or explode, possibly resulting in severe injury or death.

6. Due to the possibility of fire and exposure to extreme heat, the DSIS / LPIS must be stored either completely full or completely empty. If the system is exposed to fire while partially filled, the cylinder wall may rupture before the internal pressure becomes great enough to burst the safety plug assembly. For this reason, Aqua Lung recommends that the cylinder be completely emptied and the handwheel closed to prevent the entrance of moisture before storing the system for an indefinite period.

7. Store the DSIS / LPIS completely dry, in a clean equipment box or sealed inside a plastic bag. When possible, avoid storing it where it may be exposed to extreme heat or an electric motor, which produces ozone. Prolonged exposure to extreme heat, ozone, chlorine and ultraviolet rays can cause premature degradation of rubber parts and components and must be prevented.

8. When transporting the DSIS / LPIS, take the necessary precautions to ensure that it is surrounded by a protective cushion to prevent undue shock or impact.

9. Do not use any type of solvent or petroleum based substances to clean or lubricate any part of the DSIS / LPIS. Do not expose the regulator to aerosol spray, as some aerosol propellants attack or degrade rubber and plastic.

INSPECTION AND SERVICE1. It cannot be assumed that the DSIS / LPIS is in good working order on the basis that it has received little use since it was last serviced. Remember that prolonged or improper storage can still result in internal corrosion and deterioration of o-ring seals and valve springs.

2. It is imperative that you obtain factory prescribed service for your DSIS / LPIS annually from a qualified technician, including a visual inspection of the cylinder and complete overhaul of the first stage regulator. You cylinder may also require hydrostatic re-testing (every 5 years, depending on cylinder size). Your DSIS / LPIS may require this service more frequently, depending on the amount of use it receives and the environmental conditions it is used in.

3. If the DSIS / LPIS is used for training purposes in salt water, chlorinated or silted fresh water, it may require service more frequently. Use in chlorinated swimming pool water will accelerate the deterioration of rubber components more rapidly than in other environments.

4. DO NOT attempt to perform any disassembly or service of your DSIS / LPIS. Doing so may cause the system to dangerously malfunction. All service must be performed by a qualified technician.

OBTAIN FACTORY PRESCRIBED SERVICE FOR YOUR DSIS / LPIS ANNUALLY. YOUR PERSONAL SAFETY AND THE MECHANICAL INTEGRITY OF YOUR DSIS / LPIS DEPEND ON IT.
