3.5.1 Working principle • The pressure regulator is a pressure-balanced, piston-equipped counter-flow regulator. The result of balancing is firmly reduced pressure (intermediate pressure) that is not affected by pressure fluctuations in the air supply (high-pressure). The regulator opens at corresponding gas pressure. The principle is called downstream regulation.
3.5.4 Redundant breathing system • The regulator unit comprises two pressure regulators. The primary regulator provides the primary breathing valve or the full-face mask valve with intermediate pressure air, and the secondary regulator provides the octopus breathing valve with intermediate pressure air. The primary regulator receives air via the reserve valve handle, while the secondary regulator is always directly supplied with air from the air cylinders. Thus the system has a backup system.
3.5.5 Pressure gauge • Pressure in the cylinder pack can be read from the pressure gauge. The pressure gauge is connected to the regulator's connecting pipe via a high-pressure hose. The air pressure affects a Bourdon tube (a pipeshaped spring) in the pressure gauge, which in turn affects the indicator. The safety valve (behind the rubber covering) on the rear of the pressure gauge opens if the pressure in the pressure gauge casing rises too much.

3.6.2 Primary breathing valve without safety pressure. • The Divator breathing valve without safety pressure has no extra safety pressure in the full-face mask at atmospheric pressure, but is ideal with regard to diving conditions as it still provides a weak overpressure. Otherwise, its functionality is identical to the Divator breathing valve with safety pressure. A rubber sealing plug replaces the safety pressure knob, and there are also a number of different inner components. 3.6.
3.7 Full-face mask and breathing valve The mask has an inner mask with separate inhalation and exhalation channels that match corresponding channels in the breathing valve. This ensures that inhalation and exhalation air is never mixed. During inhalation, air flows from the breathing valve up through the mist protection openings, over the inside of the visor and continues through the check valves in the inner mask. During exhalation, the exhaled air exits into the surrounding water via the exhalation valve.
3.8 Divator BCW Vest (Buoyancy Compensating Wing) Bungee cord to the Octopus hose Inflation hose with venting valve Quick release of weights Weight pocket Tool pocket FRONT Vent valve Anchor point for crotch strap Quick release fastener BACK Interspiro Divator BCW is a buoyancy compensator that combines high quality, durable design, weight integration and buoyancy. It is placed on the back of the diver. Divator BCW's modular design enables switching between dry-suit and wet-suit diving.
3.9 Divator Harness The Divator harness is used instead of the Divator BCW when diving with the front-mounted buoyancy vest or with a dry-suit and there is no need for extra buoyancy, e.g. when underwater work is being carried out in an upright body position with connection to surface air. There are several different versions of the Divator harness.
3.10 Divator DP1 Supply Hose System • Additional information about the Divator DP1 Supply Hose System is available in the Divator DP1 Supply Hose System User Manual.
4 Preparations before use CAUTION! It is of great importance that the measures stipulated in Section “12.3 Control and inspection” have been carried out before the equipment is prepared for use. 4.1 Anti-freezing caps The diver must carry out a visual inspection of the anti-freezing unit before beginning a dive. The inspection should ensure that anti-freezing cover is mounted in the correct position, that screws are tightened and that the anti-freezing caps are correctly mounted and not kinked.
WARNING! The anti-freezing cap should only be disassembled if there is reason to suspect that the functionality or mounting of the anti-freezing unit is incorrect. If this is the case, see Section 12.3.5. It is also very important to make sure that the anti-freezing unit is not exposed to water or dirt during disassembly and assembly. Always repeat the visual inspection described in Section 4.1 before diving. 4.
4.3 Securing the BCW or harness 1. Align the quick coupling's rail with holes on the BCW or harness with the quick coupling pins on the cylinder pack. 2. Attach the BCW or harness in the cylinder pack by moving the rail with holes into place against the quick coupling's pins until it locks. Check that the quick coupling has locked by pulling on the BCW or harness. 4.4 Securing the BCW hose 1. Place the BCW inflator hose between the rear of the BCW unit and the cylinder pack.
4.5 Securing the breathing hose in the BCW 1. Place the breathing hose between the rear of the BCW unit and the cylinder pack. 2. Move the hose up over the right shoulder strap on the BCW and attach the Velcro strip over the breathing hose 3. Attach the Velcro holders on the breathing hose around the right shoulder strap as illustrated in the figure. If necessary, adjust the length of the breathing hose to a suitable position.
4.6 Securing the octopus breathing valve in the hose 1. Carry out a visual inspection of the octopus to ensure it is not damaged. Tighten the locking nut and locking ring on the octopus breathing valve as described in Section 4.7 “Connecting the full-face mask”. 2. Connect the octopus breathing valve to the breathing hose if this has not already been done. Properly hand tighten the octopus breathing hose nut as described in Section 4.7 “Connecting the fullface mask”. 3.
4.7 Connecting the full-face mask 1. Carry out a visual inspection of all plastic, rubber and metal parts and ensure that there is no damage. Make sure that the rubber components do not exhibit signs of wear or cracking. 2. Ensure that the check valves in the inner mask are even and secured. 3. Make sure that the pressure equalization cushion is correctly placed and adjusted. 4. Check that the connection on the breathing valve is free from dirt and that the O-ring is in place in the breathing valve. 5.
7. Mount the fixing cover to secure the position of the breathing valve and tighten the screws by hand. Do not overly tighten the screws as this may pull out the thread insert thereby damaging the mask. Make sure that the O-ring is in place and undamaged. 8. Check that the locknut on the breathing valve is properly tightened. 9. Check that the locking ring on the breathing valve is properly tightened. 10. Connect the full-face mask with the mounted breathing valve to the breathing hose.
4.8 Cylinder weight 1. Check that the weight screws are tightened. 2. If the underlying weights are exchanged for another weight combination, an 8 mm Allen key should be used. CAUTION! If any of the underlying brass weights are removed in order to reduce the total weight, each of these must be switched out with plastic replacement weights in order to retain weight strength and performance.
5 Preparations before diving 5.1 Leakage and function test 5.1.1 Leakage and function test for MKIII Regulator Quick check of reserve valve 1. C lose the reserve valve handle (position C) by pressing it in as far as possible. 2. Open the cylinder valve. Check that the pressure is > 270 bar (3916 psi). 3. Close the cylinder valve. Wait one minute. Pressure drop < 10 bar/minute (145 psi/min) = OK 4. Open the cylinder valve. 5. Vent the octopus breathing valve by pressing the air discharge button.
5.1.2 Leakage and function test for BCW. 1. Inspect the BCW vest so that it does not show any signs of material deterioration or wear. 2. If the primary breathing valve with safety pressure is used, it is important to ensure that the breathing valve knob is in the closed position. If the primary breathing valve without safety pressure is used, this step can be skipped. 2. Carefully open the cylinder valve completely if this has not yet been done. Close the valve a quarter of a turn! 3.
5.3 Putting on the full-face mask 1. Pressurize the Divator diving apparatus according to the description in Section 5.1 “Leakage and function test”. If the Divator fresh air hatch is used, it should be opened. 2. Pull out the rubber straps on the rubber-band device as far as possible by grasping the metal buckles and pulling them out. 3. Adjust the pressure equalization cushion (there are several positions) so that it is easy to reduce the pressure in your ears and breathe through your nose unimpeded.
Comment: Only tighten the top strap at the forehead to prevent if from being loose. If the top strap and the upper rubber straps are excessively tightened, the mask will press tightly against the diver's chin resulting in chin fatigue with accompanying headache and/or jaw pain. 7. Read the pressure gauge. Breathe in deeply to automatically activate the safety pressure (if this is used), or alternatively press lightly on the vent button. Stop breathing and listen for signs of leakage.
10. Check the pressure gauge to ensure that the pressure is sufficient for diving. 5.4 Checking reserve valve handle position 5.4.1 Diving with Divator diving apparatus. Check that the reserve valve handle is in the diving position (D), or move the handle to the D position when the Divator diving apparatus is pressurized. 5.4.
5.5 Attaching weights When the Divator diving apparatus is ready for use, the diver's assistant mounts the weight on the weight bracket for the Divator Lite cylinder pack, and secures it with the spring pin with the open end facing downwards. Comment: When the spring pin has been inserted to secure the weight, it must be turned a quarter turn around its own axis in order for it to lock.
6 Diving 6.1 Checks during an ongoing dive • Read the pressure gauge regularly. • Make sure that other equipment does not block usage or access to necessary controls and components. • Check for leaks. Important: The dive must be terminated when the diver activates the reserve valve. The dive should be planned with the aim of not using reserve air. 6.2 Diving in cold water Diving in cold water is full of risk and requires special planning and special preparations.
6.2.2 Breathing valve All breathing valves from Interspiro provide air during inhalation. When the diver inhales, air flows from the breathing hose through the breathing valve into the diver's lungs. Expansion of the supplied air causes the air at the valve inflow to be cooled to approximately -10°C (14°F) at a water temperature of 0°C (32°F).
6.2.5 Routines during repeated dives in ice-cold water and/or at low air temperature 1. Prepare the next diving occasion by shaking out the water from the full-face mask and the breathing valves. Disassemble the equipment's components as quickly as possible to prevent them from freezing solid to each other. 2. Press the full-face mask against your face at the same time as you depress the breathing valve's vent button for a few seconds.
7 after diving 7.1 Removing Divator 1. The assistant should loosen the spring pin and remove the weight, preferably while the diver is still in the water. 2. Loosen the full-face mask's rubber-band device. If the primary breathing valve with safety pressure is used, the safety pressure is closed by pressing the breathing valve knob in towards the valve housing. Remove the full-face mask. 3. Release the dry-suit's quick coupling. 4. Open the waist buckle and belly-belt if the BCW is used. 5.
6. Detach the BCW hose and remove the Divator BCW or harness from the cylinder pack by pressing in the locking mechanism on the upper part of the Divator BCW or harness. Maintain pressure and pull the carrying handle to loosen the quick coupling. 7. Remove the regulator from the cylinder pack. 8. When the regulator unit is not connected, the cylinder valve must be provided with a safety plug that is tightened by hand. The regulator connection nipple must be protected with the yellow protective cap. 9.
8 Filling 8.1 Filling Interspiro fully composite cylinders The following measures must be performed when filling Divator Lite cylinders with an initial pressure less than 30 bar (435 psi). • The filling rate must be limited to no more than 30 bar (435 psi) a minute. Using an Interspiro Filling Adapter is recommended. • The cylinder pack must always be filled in an upright position with the valves pointing upwards.
Using the filling adapter 1. Detach the pressure regulator or the plug from the cylinder valve and connect the filling adapter to the cylinder valve. Tighten the knob on the adapter by hand to prevent leakage. 2. Connect the filling hose to the filling adapter and tighten the coupling by hand to prevent leakage. 3. Open the cylinder valve and fill the cylinder pack.

11 Service and testing schedule Service and testing shall be performed according to Service and testing schedule 30500. Visit www.interspiro.com for latest revision.
12 Maintenance 12.1 Cleaning 12.1.1 After each dive 1. If the equipment is very dirty or in need of disinfection, see Section 12.2 “Monthly cleaning”. 2. Pressurize the Divator diving apparatus by opening the cylinder valve. 4. Rinse the face mask and the breathing valve carefully in clean water. Remove water and dirt by pressing the vent button and blowing air through the valve. Repeat the measure a couple of times until the valve is completely clean. 5.
12.2 Monthly cleaning 1. Assemble the air cylinder pack, regulator and full-face mask/breathing valve. 2. Open the cylinder pack and check the pressure on the pressure gauge before cleaning begins. To prevent water from entering the regulator and to detect leakage, there should always be pressure in the cylinder pack. Replace the cylinder pack if the pressure gauge indicates less than 270 bar (3915 psi). 3. If the full-face mask is used, the fixing lock should be removed by loosening the screws.
11. Close the cylinder and screw in the sealing plug by hand. The sealing plug should only be tightened by hand on a cylinder pack that is to be filled. 12. Allow the cylinder packs to dry. 13. Shake off the water from the other parts and allow them to air dry. Dry thoroughly. 14. Fit the breathing valve into the full-face mask. Turn the breathing valve counterclockwise to attach the breathing valve bayonet coupling. Attach the fixing cover. 15. Remove the cylinder pack for filling.
Disassembly 1. Clean the full-face mask/breathing valve according to the instructions for monthly cleaning. 2. Remove the breathing valve if the full-face mask is used. If a mouthpiece is used, remove the mouthpiece section. 3. Remove the exhalation unit from the breathing valve. Hold the exhalation unit and the valve housing and loosen the locking ring.
4. When the exhalation unit has been removed, press the threads to remove the diaphragm unit from the exhalation unit. Place your hand over the diaphragm unit to prevent it from getting lost. 5. Clean the spring, cover, diaphragm unit and mouthpiece in water. Carefully pull the diaphragm unit so that the diaphragm is stretched and the dirt on the surface can be removed. Make sure that the diaphragm unit and the loose parts are not damaged. 6. There is a white plastic sealing disc on the diaphragm unit.
Assembly 1. Replace the sealing disc in the diaphragm unit and then place the sealing disc with spring in the cover and press the diaphragm unit together. Check that the spring fits into the recess for the sealing disc. 2. Set the inhalation unit in the breathing valve and screw the valve housing together with the locking ring. Comment: Only the locking ring should be turned. Otherwise there is a risk that the O-ring will be moved causing a leak. 3.
If the mouthpiece is used, make sure that there is no O-ring in the O-ring groove; mount the mouthpiece in the breathing valve and check that the rubber flange on the inside of the mouthpiece runs in the O-ring groove. Fix the mouthpiece with the hose clamp. 12.3 Periodic checking and inspection The checks described in this section must be regularly carried out between dives (after one diving occasion and before the next one). 12.3.1 Check the reserve valve handle 1.
12.3.3 Checking hoses Check all hoses by bending and pulling them, and by making a note of any damage, cracks, discoloring and changes in hardness. If the equipment is defective or damaged, it must be repaired by a service technician approved by Interspiro. WARNING! A pressure drop caused by a rupture on a dry-suit hose is just as great as any caused by a rupture in the breathing hose. For this reason, be careful when carrying out the inspection! 12.3.
1. Remove the anti-freezing cover. The antifreezing caps are mounted inside. 2. Make sure that the anti-freezing caps are internally free of water. 3. If they contain water, the unit must be inspected and, if necessary, serviced by a service technician approved by Interspiro. 4. Check that the anti-freezing caps have not been damaged. If damage is detected or suspected, the anti-freezing caps must be replaced. Make sure that the anti-freezing caps are not deformed when installing them in the base. 5.
12.3.8 Controlling the angle of the cylinder valve The cylinder valve must not be angled in relation to the intersection between the two halves of the handle. If the angle of the cylinder valve is incorrect, the cylinder pack must be returned to a service technician approved by Interspiro. 12.3.9 Checking the cylinder pack If the cylinder pack is filled, it must be equipped with a safety plug that has been tightened with a wrench.
12.4 Repairs 12.4.1 General This section describes the repairs that users may carry out personally. Repairs other than those described here must be carried out by a service technician approved by Interspiro. 12.4.2 Regulator Replacing the O-ring for the high-pressure connection This O-ring is placed in the connecting nipple on the regulator's high-pressure connection.
12.4.3 Harness Replacing a belt buckle There are two belt buckles - one on the left and one on the right. When a hip belt is correctly positioned, the free ends of the belt will be on the outside of the hip belt to facilitate easy tightening. 1. Make sure that the outward-bent parts of the buckles are facing away from the user (“the outside”). Pull the hip belt from the inside through the slot nearest the buckle. 2. Thread the belt through the second slot from the outside of the buckle. 3.
WARNING! The full-face mask's O-ring must not be used when the breathing valve is used together with a mouthpiece. Otherwise, there is a risk that the mouthpiece will come loose. 12.4.5 Full-face mask Replacing a strap device Begin with the strap device's upper strap. Thread the strap through the buckle from the inside of the fullface mask. The IS logo in the middle of the strap device must be visible after installation.
13 Transport and storage 13.1 Storage 13.1.1 Air cylinders • Before long-term storage, the air cylinders must be filled and equipped with safety plugs. Make sure that necessary warning notifications have been posted at the door of the storage area in accordance with all current and applicable regulations. 13.1.2 Harness or BCW • When being stored, the harness or BCW should be cleaned and dried and subsequently stored in a dry place. 13.1.
