    1 TECHNICAL DESCRIPTION 1.1 DIVATOR DP1 SURFACE SUPPLY DIVATOR DP1 Surface Supply features a unique patented supply hose and a surface supply dive control panel enabling rapid deployment in remote locations. Divator DP1 is a surface supply diving system with an operating pressure of up to 300 bar (4350 psi).

  • Page 8: Surface Unit

    DIVATOR DP1 comprises an automatic shuttle valve, low air warning whistle, pressure gauge, adapt- er hoses for air supply cylinders and a connection to the high pressure air lifeline hose for the diver. The connections to the air supply sources are suitable for both 200 and 300 bar (2900 and 4350 psi) pressure "DIN"...
  • Page 9 Connection to ordinary outlet of surface unit With the adapter for two divers (optional) the Divator DP1 is enabled to supply air for two divers simultaneously, as with the version for one diver, these divers will have a surface supply unit that is self-compensating for depth variations.

  • Page 10: High Pressure Air Lifeline Hose

    Quick Connection to Diver The Divator DP1 Surface Supply has been approved with an air supply hose up to 120 meters (396 feet) in length for a maximum depth of 50 m (164 feet). The high pressure air lifeline hose is attached to the diver with a quick-connection on the P+ regulator, it attaches to the diver's manifold on the Divator regulator .
  • Page 11 The high pressure air lifeline hose including relieving loops, hose, belt and carabine hook is designed to withstand the demanding requirements of operational diving. Use of the high pressure air lifeline hose is subject to the normal operational procedures and precautions that apply to all diving equipment.

    Surface Supply as long as the DP1 Surface Supply pressure is greater than 20 bar (290 psi) at a dive depth of 50 meters (150 feet) or less. Note: The DIVATOR DP1 Surface Supply has a low air warning whistle that is activated at 55 bar (790 psi).
  • Page 13 When using the DIVATOR DP1 Surface Supply, if the surface air supply is interrupted air will be taken from the diver's SCUBA cylinders. The diver will receive active breathing resistance warning when the DIVATOR SCUBA cylinder pressure has dropped to approximately 65 bar (940 psi).

    2 PRE-DIVE PROCEDURES 2.1 HIGH PRESSURE AIR LIFELINE HOSE HANDLING To avoid kinking of the supply high pressure air lifeline hose it is important to wind the hose in such way that it is free from twisting (kinks). Kinks can result in flow restrictions. The high pressure air lifeline hose should be wound up pressurized in figures of eight with a diameter greater than 500 mm (>...

    3 OPERATING PROCEDURES 3.1 CHECK LIST The check list below can be found on the inside lid of the Surface Unit. Please note that the text on the check list may vary depending on language region or user requirements. 3.2 SURFACE ATTENDANT OPERATING PROCEDURES 1.

    9. Open one cylinder valve. Check that the audible alarm sounds, and that the alarm stops after a short period when the pressure increases. Check for leaks. Make a note of the pressure in the first cylinder. 10. Close the first cylinder valve and open the vent valve to release some pressure. Close the vent valve. 11.
  • Page 17 WARNING! If the high pressure air lifeline hose is connected to the diver and dived without being pres- surized the water pressure may become higher than the air pressure on the inside of the hose and may partially fill the inside of the hose with water. If the surface attendant then realizes his fault and pressurizes the hose, water could be supplied to the diver instead of air.

  • Page 18: Emergency Procedures

    4 EMERGENCY PROCEDURES 4.1 LOW AIR SUPPLY PRESSURE, SURFACE In an emergency the surface supply can be used until the air supply pressure has dropped to approxi- mately 20 bar (290 psi). WARNING! The high pressure air lifeline hose should never be re-pressurized during the dive if the pressure in the hose has been lower than 10 bar (145 psi).

  • Page 19: Post Dive Procedures

    2. Close the air supply cylinders valves and the cylinder valve on the bail out cylinder. 3. Depressurize the Divator DP1 Surface Supply by gently opening the vent valves on the adapter hoses. To depressurize faster, use the purge button on the breathing valve or use the pressure vent handle.

  • Page 20: Maintenance And Testing Schedule

    6 MAINTENANCE AND TESTING SCHEDULE This schedule is valid for Divator DP1 surface supply diving equipment. The schedule shows the minimum requirements for maintenance and testing as recommended by Interspiro. Local requirements may di er due to regulations and environmental conditions.

  • Page 21: Maintenance

    The leakage of hoses and couplings is checked by pressurizing them and checking that the pressure is maintained (maximum pressure drop 1 bar/min (15 psi/min)). If any part fails the leakage test. Replace the part with Interspiro original parts. Preparation: Prepare two air cylinders filled to the same pressure, but at least 250 bar (3630 psi).

  • Page 22: Regular Maintenance

    5. Listen for leaks along the length of the high pressure air lifeline hose including P+ regulator and adaptor hose. It may be necessary to use leak spray or soap water solution to detect leakage. 6. Pay close attention that leakage is not coming from the shuttle valve housing or whistle. 7.
