What to do if the Weinmann Fan shows < 2,7 bar alarm (oxygen pressure too low)?

If the Weinmann Fan displays a < 2,7 bar alarm, indicating low oxygen pressure, the oxygen cylinder may be nearly empty (in this case change the O cylinder), the oxygen valve may be closed (in this case open oxygen valve), the pressure reducer may be defective (in this case replace pressure reducer) or there could be a kink or blockage in the oxygen hose (in this case take action to correct).
