1. Ensure the spring action cuts off the Oxygen flow when the button is released Check that the whistle does not sound when the Oxygen flush is operated If this occurs check that the Oxygen Cylinder Valve is fully open If the problem is not rectified instruct the service engineer to check a filters and Non return valves for restriction b the pressure of the primary Oxygen regulator Connect the oxygen pipeline and close the cylinder valve and repeat tests 3 6 Auxiliary Outputs Test Check outputs for security and correct function With a suitable flowmeter measure the output from each outlet to ensure that greater than 100 litres min can flow to free air Ensure that the oxygen failure alarm does not function during this test Repeat the test for both pipeline and cylinder supplies 7 FAULT FINDING 7 1 Introduction Provided the Anaesthetic Machine is regularly serviced and correctly used it is unlikely that seri ous component faults will occur After several years usage some items may require replacement and regular performance checks see section 8 To trace possible faults refer to the Fault Diagnosis Table which will indicate the required action In many cases apparent machine faults may be attributable to causes other than machine mal functions these causes are also listed 39 FAULT FINDING 7 2 Fault Diagnosis Table Component Cylinder pressure reducing valves
