Note As the apparatus has a restrictor fitted to protect the high pressure hose and gauge it takes some time before the pressure gauge shows the full pressure Hence it is necessary to wait about a minute in order to fully pressurize the system 4 Close the valve and check for leakages during 1 minute by checking that the pres sure gauge reading does not fall by more than 10 bar 5 Switch on the positive pressure by slowly moving the black lever out a little from the valve housing until a small air flow is heard 6 Read off the gauge when the audible alarm sounds The pressure should be min imum 50 bars European standard EN 137 7 Depressurize the system by turning on the positive pressure fully 8 Turn off the positive pressure Donning the apparatus 1 Before donning check that the shoulder straps are pulled back and that the waist strap male buckle is adjusted outwards 2 Don the apparatus The cylinder valve shall be downwards 3 Grip the free ends on the shoulder straps and pull down until the back plate fits comfortably During this manoeuvre it is preferable to relieve the weight of the apparatus by a little jump or resting the apparatus on something 4 Press the waist strap female and male buckle halves together Adjust and tighten the waist strap by pulling on the free end The waist strap goes around and can eas ily be adjusted so that the buckles come in front of the body 5 C

8. aved Technical description The SPIROMATIC 90 U models are self contained breathing apparatus SCBA for work in contaminated hazardous environments The apparatus consists of the following main components Basic model e Face mask with breathing valve the SPIROMATIC mask Air supply The SPIROMATIC 90 U apparatus has been tested in accordance with EN 137 for types ofuse specified EC Type examination Directive 89 686 EEC by SGS Yarsley ICS Ltd Weston super Mare BS22 OWA UK Notified Body No 0120 The apparatus uses a single compressed air cylinder for the air storage The cylinder is mounted onto an anatomically designed backplate The high pressure in the cylinder is reduced in two steps or stages down to a breathable pressure This is done to achieve lowest possible resistances and high capacity when breathing in the unit i e a very low breathing exertion even at very high workloads The first reduction of the high pressure is performed in the balanced piston type pres sure regulator The second reduction to breathable air is performed by the breathing valve located at the face mask The breathing valve is a demand valve which means that the valve senses the demand for an inhalation of air and it opens to permit ex actly the air flow demanded The inlet valve closes when the inhalation stops and an exhalation valve opens upon exhalation The breathing valve creates a small positive pressure inside the face mask du
9. ed The pressure regulator used in the Spiromatic 90U models is a balanced piston pres sure reducer with an extremely high flow capacity The very high capacity ensures that the positive pressure is maintained in the mask even at low cylinder pressures and at extremely high breathing rates The pressure regulator is fitted with a safety valve which prevents the pressure to reach unsafe levels Audible warning The warning device like the pressure regu lator is of a plug in type It means that the same simple servicing system as for the regulator can be used The unit has a pressure reducer built into the unit which reduces the cylinder pressure and allows a small constant flow When the cylinder pressure reaches a pressure of 55 5 bar 5 5 0 5 MPa the regulator opens and feeds the audible alarm The alarm signal is approx 95 dB and continues to sound until the cylinder contents are depleted Note Before disconnecting the audible warning unit it is important that the system is depressurized THE SPIROMATIC MASK The SPIROMATIC Mask has been designed as a unit consisting of a mask and a breathing valve where the components are connected via a bayonet coupling and locked together with a cover or a speech diaphragm Face mask The Spiromatic face mask has been tested in accordance with EN 136 for types of use specified and are ap proved for use with compressed air breathing apparatus The face mask with
