DIVATOR RS4 ADVANTAGES The RS4 regulator is designed to make your dive efficient and safe. It has a high air flow capacity that ensures sufficient air supply to the primary and the secondary (octopus) breathing valve at the same time, regardless of the depth of the dive. This makes the RS4 an ideal regulator for professional diving and rescue missions. MODULAR The RS4 has a range of versions with different covers to choose from. Choosing the right regulator configuration for your specific diving needs will give you a safe and functional dive. ANTI-FREEZE The unique anti-freezing device on the RS4 is designed by Interspiro s engineers to be dry in all conditions, this will eliminate problems like freezing and free-flowing which other regulators on the market may encounter. This is possible because the regulator s reference chamber is kept dry by high pressure gas (high pressure gas can only contain negligible amounts of moist) and has a overpressure which ensure that no water may enter the reference chamber. ADJUSTABLE COVERS Loose hanging or protruding hoses are a huge safety risk. The RS4 has adjustable covers that makes it possible to adjust the hoses to lie secure, near the divers body, this will make the dive more ergonomic and safe. ROBUST SHOCKPROOF DESIGN The RS4 has an outer shell made of durable black rubber that protects the regulator from accidental impacts or chocks. This shockproof design will keep the regulator in a good condition and prolong its usage time. INCREASED USAGE POSSIBILITIES The RS4 can be used together with both a single cylinder and a cylinder pack. This ensures that you always have a regulator that suits your needs. A perfect match is to combine the RS4 with Divator LITE which is a perfectly balanced cylinder pack. Divator LITE has a low profile that allows for safer access to confined spaces and minimizes resistance in current waters together with being the lightest diving cylinders in the world. USING RS4 TOGETHER WITH INTERSPIRO DIVATOR DP1 The DP1 is a truly light weight and portable surface supply that provides full cylinder pressure to the diver at depth. Using DP1 together with RS4 will give the diver even more security when diving in tough conditions. The DP1 supply hose can be used as a lifeline and if using a communication, it can be attached to the hose. DIVATOR RS4 REGULATOR VERSIONS The RS4 Regulator is available with DIN or YOKE connection, both versions are available in four configurations. The DIN version are equipped with a parking spot plug for keeping the dust cover in place during the dive. 6

2-PORT SCUBA (DRY SUIT/BC) The RS4 regulator, 2-port SCUBA, is intended as a regulator to be used as an Inflation regulator for a dry suit and/or for a BC as a stand alone unit with a separate small cylinder. Delivered without pressure gauge and hoses. The RS4 regulator has two HP outlets (7/16 ) for a pressure gauge or a Divator HUD. There are two LP outlets (3/8 ) for a dry suit and/or a BC hose (or it can be used for any other LP hose).

ASSEMBLING THE DIVATOR RS4 ON THE CYLINDER Assemble the RS4 regulator onto the high pressure outlet on the cylinder, either in the parallel mode or in the traditional standard SCUBA mode (as seen on pictures). Photo shows traditional SCUBA mode. Photo shows parallel mode. ATTACHING A DEVICE TO THE SECOND HIGH PRESSURE OUTLET It is possible to attach a HUD or other HP device to the second high pressure outlet fitted with a parking plug. Interspiro recommends that this is done by an Interspiro certified service technician. 1. Remove the parking plug with a 6 mm hexagonal key. 2. Attach the HP device according to it s manual. When detaching the HP device: reassemble the parking plug with a 6 mm hexagonal socket fitted on a torque wrench to 15 Nm. 9

ATTACHING AND DIRECTING HOSES ON DIVATOR BC USE OF INTERSPIRO HOSES If using Interspiro hoses, tighten the hoses to 10 Nm. USE OF OTHER HOSES THAN INTERSPIROS Make sure that the hose has a working pressure of at least 34 Bar (490 Psi) and a burst pressure of at least 100 Bar (1450 (Psi). Tighten them according to the hoses user manual. CONNECTING THE BREATHING HOSE Connect the breathing hose to the full face mask (or mouthpiece) by screwing it on fingertight. If an over pressure mask is fitted, close the lever. CONNECTING THE INFLATION HOSE 1. Put the inflation hose for the BC through the upper elastic band on the corrugated inflation hose. 2. Pull the hose until you can connect it to the power inflators connector. 3. Adjust the hose length so that both hoses are parallel. Fasten the inflation hoses with the left velcro holder on the BC. CONNECTING THE OCTOPUS BREATHING HOSE AND VALVE 1. If a breathing hose for octopus is fitted, put the hose through the right inner side of the BC bladder and pull it out in its full length. 2. Connect the hose to the octopus breathing valve by screwing it on finger tight. Close the Lever on the octopus breathing valve. 3. Bend the hose one third of the length from the regulator. Insert the bent section of the hose through the elastic cord located on the upper back part of the BC harness. 4. Connect the octopus breathing valve to the octopus mouthpiece holder (optional) in a suitable position or store it in the BC s right outer pocket. ATTACHING THE DRY SUIT INFLATION HOSE If a dry suit inflation hose is fitted, put it through the right inner side of the BC harness. ATTACHING THE RS4 REGULATOR PRESSURE GAUGE Fasten the elastic cord with hook (attached on the pressure gauge) on a suitable D-ring on the BC. Make sure it is easily accessible during the dive. DIRECTING THE DIVATOR DP1 HOSE If the DP1 hose is fitted, make sure it is directed through the left inner side of the BC bladder. Store the DP1 hose in the BC left outer pocket. Close the zipper if you are not performing a DP1 surface supply dive. SURFACE SUPPLY DIVING USING THE DIVATOR DP1 1. Before using the DP1 Surface Supply diving system together with the RS4 SCUBA make sure that the attendant has: connected the air cylinders done the pre-dive checks on the DP1 equipment checked that air is fed to the DP1 regulator according to the DP1 manual. 2. Connect the RS4 quick connector for DP1 to the DP1 regulator. 3. Tighten the locking ring fully. Loosen it a quarter of a turn. 4. Put the DP1 Surface Supply assembly in the left BC pocket for security and protection. 5. Close the zipper on the BC pocket to avoid the regulator from falling out during diving. 6. Connect the carabiner on the DP1 surface supply hose to the lifebelt worn by the diver. For further instructions see the DP1 user manual. 10

PRE-DIVE PROCEDURES OVERALL CHECK 1. Make sure that the RS4 regulator is clean and free from sand and/or debris from previous use. 2. Inspect the regulator to detect if it has any signs of damage. A damaged or defective regulator must be replaced or repaired by an Interspiro certified service technician. 3. Check all hoses by pulling and bending them while inspecting for damage, cracks and discolouration. If the high pressure hose to the pressure gauge is found to be defective or damaged, it must be replaced by an Interspiro certified service technician. 4. Check that the protective band is attached to the reliefe valve otherwise replace it with a new protective band. Protective band order no. 346 190 053 (10 pack). WARNING! THE AIR LOSS CAUSED BY A BREAK IN THE DRY-SUIT HOSE IS JUST AS GREAT AS THAT CAUSED BY A BREAK IN THE BREATHING HOSE. THEREFORE, CHECK THOROUGHLY! The RS4 regulator has a restrictive orifice in the high pressure hose that limits the air flow to the pressure gauge. The restriction protects the user and the equipment if the hose burst. CHECKING O-RINGS O-rings that are exposed to sunlight, salt water, chemicals (including mild detergents), and ozone suffer ageing and may become defective. 1. Check all visible O-rings. 2. Replace all cracked or damaged O-rings. NOTE! IF IT IS A DIN CONNECTION, TIGHTEN THE CYLINDER VALVE COMPLETELY TO PREVENT THE O-RING ON THE REGULATOR CONNECTION NIPPLE TO COME OFF. If using a DIN connection and the O-ring on the regulator connection nipple comes off. Put a new O-ring on the nipple by pushing it in place. O-ring order no. 336 190 272 (10 pack). LEAKAGE AND FUNCTION TEST OF THE DIVATOR RS4 REGULATOR 1. Assemble the diving apparatus. 2. If using the primary breathing valve with safety pressure lever, make sure that the safety pressure lever is in closed position. 3. Open the cylinder valve slowly and observe the pressure gauge. Check that the pointer moves normally and smoothly. If the pointer moves irregularly or not at all, the pressure gauge is faulty. When the cylinder valve is fully open, then close it a quarter turn. 11

4. Check the pressure gauge to make sure that there is enough air pressure in the cylinder for the planned dive. Interspiro recommends that the cylinder should be full before every dive. 5. Press the inflate button on the BC inflator to make sure that it inflates the BC bladder. Push the dump button on the inflator to make sure that it drains the BC bladder from air. 6a. If using a primary breathing valve with safety pressure, turn the safety pressure lever to the open position. Check that a strong flow of air is heard. Reset the safety pressure lever to the closed position. 6b. If using a primary breathing valve without safety pressure, press the purge button on the breathing valve. Check that a strong flow of air is heard. Release the purge button. 7. If using a octopus breathing valve together with the primary breathing valve, press the purge button on the octopus breathing valve. Check that a strong flow of air is heard. Release the purge button. Close the locking lever against the valve housing. 8. Test the entire system for leaks with the following steps. Close the cylinder valve. Wait for one (1) minute. Listen for leaks. Open the cylinder valve while watching the pressure gauge. Check that the needle does not rise by more than 10 Bar (145 Psi). CAUTION! IF LEAKAGE IS GREATER THAN THE SPECIFIED VALUE, ANOTHER LEAKAGE HAS BEEN LOCATED OR IF THE EQUIPMENT IS FOUND TO BE DEFECTIVE OR DAMAGED, THE EQUIPMENT MUST BE REPAIRED BY AN INTERSPIRO CERTIFIED SERVICE TECHNICIAN. 9. Close the cylinder valve. 10. Check that the pressure gauge needle moves evenly while venting the system by pressing the purge button (or turning the safety pressure lever to open) on the breathing valve. CHECKS DURING DIVING 1. Check the pressure gauge repeatedly to monitor air consumption. Terminate the dive with ample air pressure to be able to return safely to the surface or to the entry point of the dive. 2. Check for leaks or abnormal behaviour of the RS4 regulator (small bubbles will occasionally leave the anti-freeze device and are expected when ascending, this is natural). 3. Check that optional equipment fitted to the RS4 regulator can be reached and managed. 4. If using a DP1 surface supply together with the RS4 regulator, check that air is not consumed from the worn cylinder. See the DP1 surface Supply user manual for additional details. WARNING: WHEN DIVING WITH THE RS4 REGULATOR THE DIVER S ONLY WARNING OF LOW AIR PRESSURE IS BY REPEATEDLY MONITORING THE PRESSURE DROP OF THE PRESSURE GAUGE. WARNING: IF USING THE DP1, THE ONLY INDICATION THAT THE DIVER HAS SWITCHED FROM SURFACE SUPPLY TO THE SCUBA CYLINDER (BAIL OUT) IS A DECREASE IN THE DIVER S PRESSURE GAUGE. 12

DIVING IN COLD WATER The RS4 regulator is equipped with a unique anti-freeze device that is specially constructed for extreme cold water diving. Cold water diving is dangerous and requires special planning, training and preparation. Make sure that the diver and surface support have appropriate training and experience in diving during cold water conditions before conducting a cold water dive. POST-DIVE PROCEDURES 1. If using the RS4 SCUBA together with the DP1 surface supply. Disconnect and vent the DP1 according to the DP1 surface supply user manual. 2. Pressurize the RS4 SCUBA (if not already done). 3. Rinse all parts of the RS4 SCUBA in clean water. If the equipment is very dirty, use a brush and a neutral cleaning agent for extended cleaning. For a detailed description of how to clean the face mask/breathing valve and BC see each product s user manual. 4. Close the cylinder valve. 5. Press the purge button on the breathing valve to vent the regulator. Venting may take as long as 30 seconds. The O-ring sealing between the regulator and the cylinder valve may be damaged if it is removed when there is pressure remaining. 6. Remove the RS4 regulator from the cylinder. 7. Allow all regulator parts to dry. 8. Disconnect and dry the rest of the RS4 SCUBA equipment according to each product s user manual. 9. Blow any moisture out of the cylinder valve by opening the valve and allowing air to escape for 1 to 2 seconds. 10. Close the cylinder valve and tighten the cylinder valve plug by hand (if fitted). The cylinder valve shall always contain a safety pressure of at least 2 Bar (29 Psi). 11. Put the dust cover on the regulator connection nipple for protection. 12. If the equipment is faulty or damaged, it must be repaired or replaced by an Interspiro certified service technician. 13. The equipment shall be thoroughly dried if it is to be stored in a bag/box for more than a few hours. WARNING! BLOW-OFF NOISE AND PRESSURE SURGES MAY CAUSE HEARING DAMAGE. ALWAYS USE EAR PROTECTORS WHEN FILLING AND EMPTYING AIR CYLINDER PACKS. 13
