  • Page 2 Kirby Morgan Manifold Block If you use an EXO-26 or other full face mask for surface-supplied div- ing, a manifold block which has a one way valve (also referred to as a “non-return” valve) and provides for correct attachment of the umbili- cal is essential.
  • Page 3 Kirby Morgan Manifold Block The one way valve is a very important component. It prevents the flow of air out of the mask in the event of a sudden lowering of pressure in the umbilical supply hose due to an accidental break in the hose or fitting. Not only would the emergency air be lost if the one way valve failed (con- current with a hose or fitting break) but the diver could be “squeezed,”...

  • Page 4: Testing The Manifold Block

    Kirby Morgan Manifold Block Testing the Manifold Block Prior to assembling a bailout system, the one way valve and emergency valve should be tested for proper function. Equipment Needed: -Manifold Block -Bailout bottle -1st Stage regulator w/octopus and scuba reg hose attached -DCS system with an umbilical supply hose -Bucket of water...
  • Page 5 Kirby Morgan Manifold Block Disconnect the hose from the emergency valve. 5) Quickly open the emergency valve by turning the knob. You should hear the trapped air escaping through the emergency valve. Testing The Emergency Valve 1) With all the accessory holes plugged on the manifold block, attach the umbilical hose to the one way valve.
  • Page 6 Kirby Morgan Manifold Block The diver’s umbilical must always be connected by a snap hook to the harness. Note the submersible pressure gauge used to monitor the bail-out supply. WARNING Never dive without attaching the umbilical to some type of harness or clip on the diver’s body.
  • Page 7 Kirby Morgan Manifold Block The mounting plate secures the manifold block to the diver’s harness. Mounting plate Bail-Out Bottle (Emergency Gas Supply) The diver should always dive with a bailout bottle when diving surface- supplied, no matter how experienced or what the water depth. Should the diver become unexpectedly entangled underwater, or if the top side air supply fails, the bailout bottle must provide the few extra minutes of air the diver needs to deal with the emergency and return to the surface.
  • Page 8 Kirby Morgan Manifold Block Over-Pressure Relief Valve The first stage regulator must have at least two low pressure ports. One port is used for the connector hose to the emergency valve and the second is used to install an over-pressure relief valve (Part #200-017). If the first stage develops a leak, the full pressure of the tank could be placed on the low pressure hose.

  • Page 16 Kirby Morgan Manifold Block WARNING Do not use any sealant on pipe threads on Kirby Morgan products other than Teflon tape or other approved sealants. Other sealants may not be oxygen com- patible and may lead to fire or explosions which may cause severe personal injury or death.
  • Page 17 Kirby Morgan Manifold Block 11) Test the valve by attaching it to an emergency air supply source. There must be no leakage of gas past the stem or through the packing nut. Turn on the bailout bottle and leave the supply on for several hours. There must be no drop in pressure in the system if the valve is operating properly.
  • Page 18 Kirby Morgan Manifold Block and fresh water. Cleaning for 15 minutes in an ultrasonic sink, if avail- able, with the 50/50 vinegar solution is highly recommended. Repair parts are available. Normal replacement parts include the O-ring, soft seat, spring, and hex nut. The O-ring should be replaced at least an- nually.
  • Page 19 Kirby Morgan Manifold Block nut, if either part is excessively corroded or shows signs of wear and/or damage. Inspect the soft seat for nicks, cuts, and wear and replace if any damage is found. Replace the entire assembly if any damage to the valve body is present.
  • Page 20 Kirby Morgan Manifold Block DANGER Do not use oxygen, or mixed gas contain- ing more than 23% oxygen by volume, for lift checking the relief/bleed valve. The use of oxygen, or mixed gas, in a high- pressure supply system not designed and cleaned for oxygen service, can result in a fire or explosion causing serious injury or death.

    Kirby Morgan Manifold Block (1) in (clockwise) 1/8th turn. Slowly bring up pressure and recheck. Continue this procedure as necessary until the relief valve consistently vents at a pressure between 180- 200 p.s.i.g. (12.40-13.78 bar). If the valve does not start venting when the gauge reads 200 p.s.i.g. (13.78 bar), slowly back out on the adjustment screw (counter clockwise) until the valve starts venting, forming bubbles in the soap solution.
  • Page 22 Kirby Morgan Manifold Block Reassembly of the Manifold Block Assembly. 1) Apply Teflon tape to the pipe threads on the Emergency Gas Supply valve starting two threads back from the open end of the pipe thread. Only one and one half wraps of tape is all that is necessary. 2) Reinstall the emergency valve into the manifold block and tighten.
