Leak test

102
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-Pro>" for the
necessary tubing required for proper leakage testing.
• 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.
• Make sure that there are no cracks, breaks, fissures,
scratches, or stains on the leak test air tube. Using an
abnormal or damaged leak test air tube may result in an
inaccurate leak test or cause the endoscope to malfunction.
• Do not connect the leak test air tube if the inside of the tube,
the endoscope's venting connector, or the equipment's leak
test connector is wet. Doing so could allow water to get inside
the endoscope and cause the endoscope to malfunction.
• When connecting the leak test air tube, ensure that the tube
connector is fully and properly attached. Improper connection
will prevent the endoscope from being pressurized,
preventing an accurate leak test. This could also allow water
to get inside the endoscope and cause the endoscope to
malfunction.
• Disconnect the connecting tubes before proceeding to leak
test. Otherwise, irregularity in the endoscope may not be
detected.
• Do not attempt to disconnect the leak test air tube from the
endoscope while the test is underway or while water remains
in the basin. Doing so will allow water to get inside the
endoscope or prevent the endoscope from depressurizing,
resulting in damage to the endoscope.
• If water does not start filling the basin about 10 seconds after
the leak test has started, press the STOP/RESET button to
temporarily stop testing. Check whether the water faucet is
open. If not, open it and start leak test again.
