7.11 Manual leak test303OER-Elite OPERATION MANUALCh.7The manual leak test confirmations are linked to the scope ID's reprocessing records or leaking scope decontamination records. To prevent endoscope damage due to water invasion, always check for leaks before reprocessing the endoscope to ensure that you discover any irregularity, such as small holes, at an early stage. The leak test consists of filling the reprocessing basin with water and observing the endoscope’s outer surfaces and the leak test air tube to ensure that air bubbles are not produced continuously from any point and that there is no sound of air leakage. Refer to the “List of Compatible Endoscopes/Connecting Tubes <OER-Elite>” for the necessary tubing required for proper leakage testing.WARNINGWhen reprocessing the endoscopes after the manual leak test, be sure to straighten their bending sections. Otherwise, the reprocessing may become insufficient.CAUTION• The leak test air tube will disconnect easily if it is not attached properly or if the lock lever is degraded. Air cannot be fed properly if the leak test air tube is bent. In these cases, an accurate leak test is not possible.• Ensure that each leak test air tube is free of irregularity such as a crack, fissure, scratch, or contamination. If an abnormal leak test air tube is used, the endoscope may fail or the leak test will be erroneous. Replace it with a new tube and retry the Manual Leak test.• Do not connect the leak test air tube if the inside of the tube, the endoscope’s venting connector, or the reprocessor’s leak test connector is wet. Doing so could allow water to get inside the endoscope and cause the endoscope to malfunction.• Do not perform the manual leak test while connecting tubes are connected. Otherwise, irregularity in the endoscope may not be detected.• Do not disconnect the leak test air tubes in the middle of the process or while the water is remaining in the reprocessing basin. Otherwise, the endoscopes may fail due to the fluid entering inside them or the retention of the pressurized status inside them.• Do not leave an unused leak test air tube in the basin. Otherwise, water penetrating inside the leak test air tube may cause malfunctions of the reprocessor.7.11 Manual leak test
3047.11 Manual leak testOER-Elite OPERATION MANUALCh.7CAUTION• If air bubbles are produced continuously from an endoscope or leak test air tube during a leak test, press the Stop button on the touch screen to discontinue the leak test process, remove the scope or tube from the reprocessing basin and contact Olympus.

The touch screen will then display the error code [E092].17 Check that there are not any bubbles produced continuously from the outer surface of the endoscope and/or leak test air tube while angulating the bending section of the endoscope. Check for leaks at least for 30 seconds.CAUTION• When angulating the endoscope’s bending section, do not to let the bending section touch the reprocessing basin or retaining rack as this could damage the endoscope. After bending, straighten the bending section and place it properly on the retaining rack.• During the manual leak test, be sure to angulate the bending section. Otherwise, it would be impossible to find abnormalities in the endoscopes.

If a scope ID is input by using the scope ID master card, input by the software keyboard or input by recalling the pre-registered ID, the auto leak test is not available.CAUTION• The leak test air tube may easily disconnect spontaneously if it is connected insufficiently or, particularly if the lock lever is degraded. If the leak test air tube is bent, sufficient air supply will not be possible. In both cases, the leak test of endoscopes will be erroneous.• Ensure that each leak test air tube is free of irregularity such as a crack, fissure, scratch, or contamination. If an abnormal leak test air tube is used, the endoscope may fail or the leak test will be erroneous.• Before connecting a leak test air tube, ensure that the inner side of the tube, the venting connector of the endoscope and the leak test connector of the reprocessor are not wet. Otherwise, water penetrating inside the endoscope may cause a failure of the endoscope.• Be sure to connect the leak test air tubes securely. If the connection is insufficient, the leak test may be abnormal because the inside of the endoscope cannot be pressurized.7.12 Auto leak test
7.12 Auto leak test311OER-Elite OPERATION MANUALCh.7CAUTION• If an irregularity is found with a leak test air tube, replace it with a new tube and retry the leak test.• When a leak test air tube is not to be used, disconnect it from the connector and be sure to remove it from the reprocessing basin. If reprocessing is performed without removing it, the leak test may be erroneous.• When the auto leak test gives a “Leaked” judgment to an endoscope do not execute reprocessing program [1] to [4] on the endoscope. Otherwise, water may penetrate inside the endoscope. The endoscope should be subjected to the leaking scope decontamination and then serviced. For details on the leaking scope decontamination, refer to Section 7.15, “Leaking scope decontamination”.• The leak test result may become “Leaked” depending on the temperature of the endoscope. To perform auto leak test with the ultrasonic endoscope, wait for more than 30 minutes. To perform it with the other type of endoscope, wait for more than 15 minutes. Then, re-execute the auto leak test. If the result is “Leaked” again, the scope should be subjected to the leaking scope decontamination and then serviced. For details on the leaking scope decontamination, refer to Section 7.15, “Leaking scope decontamination”.NOTE• The covering of the bending section of the endoscope may dilate slightly during the leak test. This is not malfunction.• The auto leak test may sometimes be incapable of detecting a very small hole.
