1666.6 Loading of endoscopes and accessoriesOER-Elite OPERATION MANUALCh.6Loading of first endoscopes in the reprocessing basinOER-Elite can reprocess up to two endoscopes at one time. For details on combination of endoscope that can be reprocessed simultaneously, refer to “List of Compatible Endoscopes/Connecting Tubes <OER-Elite>”. Before placing endoscopes and accessories, thoroughly review the worst case load condition of endoscopes and accessories instructed in Section 6.4, “Worst case load condition of endoscopes and accessories”, and confirm that your endoscopes and accessories do not exceed the worst case load condition.The instruction below is compiled assuming the loading of standard-type gastroenterological endoscopes. If a different type of endoscope(s) is to be reprocessed, refer to the provided “OER-Elite Quick Reference Guide”.WARNING• The injection adapter (MAJ-1235) cannot be reprocessed with the reprocessor. If it is placed in the washing case, reprocessing of this adapter will not be effective.• When placing the endoscopes in the basin, make sure that the major parts such as the insertion tube and universal cord are loaded correctly. If the endoscopes are placed carelessly with many parts overlapping incorrectly reprocessing may be ineffective.• Do not attempt to reprocess an endoscope that is not designated for use with the reprocessor. Do not reprocess two endoscopes that should not be reprocessed simultaneously with each other. Doing so will prevent the reprocessor from functioning properly and may endanger the safety of the patient and operator. In this case, the durability of the reprocessor and its ancillary equipment cannot be guaranteed.• Place only the valves and other specified endoscope components in the washing case in the reprocessing basin. If any object other than those specified is placed in the washing case, reprocessing of the endoscope valves will not be effective.• When reprocessing an endoscope with a forceps elevator, the connecting tube must be connected to the distal end of the insertion tube. Otherwise, the reprocessing may be insufficient. For the appropriate connecting tube, refer to the “List of Compatible Endoscope/Connecting Tubes <OER-Elite>”. For the connection method of the connecting tube, refer to the instruction manual for the connecting tube.• If the distal end cap of an endoscope is removable, remove the distal end cap before putting the endoscope in the reprocessing basin. Otherwise, reprocessing may be insufficient.• Do not obstruct the circulation port inside the reprocessing basin. Otherwise, the liquid feed pressure on the endoscopes will be decreased and reprocessing will be insufficient.
6.6 Loading of endoscopes and accessories167OER-Elite OPERATION MANUALCh.6WARNING• Before starting the reprocessing cycle, be sure to confirm that the endoscopes are installed below the disinfectant solution level index line on the cover of float switch (long) and the cover of float switch (long) is attached firmly. If the endoscope is not fully submerged in the disinfectant solution, reprocessing may be insufficient.• When loading endoscopes, always be sure to disconnect cleaning accessories used for manual process from the endoscope. Otherwise, reprocessing may be insufficient.• Be sure to check that the whole of endoscope and accessories is installed below the disinfectant solution level index line on the cover of float switch (long). If the endoscope and accessories is installed above the disinfectant solution level index line, the reprocessing may be insufficient. Refer to Figure 6.37.CAUTION• When installing an endoscope that requires water-resistant cap, attach water-resistant cap by following the instructions for the endoscope. If a cap is not attached or a cap with moisture inside is attached, the endoscope will fail or malfunction.• Ensure that each endoscope is free of noticeable damage before placing it in this reprocessor. Otherwise, fluid leak may occur during the reprocessing. If damage is noticed, perform the leaking scope decontamination and contact Olympus for servicing. For details on the leaking scope decontamination, refer to Section 7.15, “Leaking scope decontamination”.• Do not let the distal end of an endoscope drop from the retaining rack or contact the reprocessing basin directly. Otherwise, the endoscope may be damaged.• When the leak test air tube is not used, disconnect it from the connector and be sure to remove it from the reprocessing basin. If reprocessing is performed without removing it, water or disinfectant solution may enter inside the tube and may cause a failure of the tube. Also, if the water or disinfectant solution entering the leak test air tube during the scope leak test enters inside the endoscope, endoscope failure may result.• When reprocessing is started without disconnecting the unused leak test air tube(s), error code [E024] is generated and the process stops. For detail on this error code, refer to “When the error code [E024] is displayed during the reprocessing process” on page 614.• When reprocessing endoscopes, always be sure to attach the retaining rack in the reprocessing basin. Otherwise, external surface of endoscopes may contact the heating portion of the reprocessing basin, resulting in possible damage to endoscopes.
1686.6 Loading of endoscopes and accessoriesOER-Elite OPERATION MANUALCh.6NOTE• In the ID inputs for each endoscope, there is no determined order for the inputs of the scope ID, user ID (load), physician ID, patient ID, and procedure ID.• To input the patient ID from a bar code, it is required to connect the optional MAJ-2130 bar code reader.• Be sure to place the endoscopes into the reprocessing basin in the correct orientation. Otherwise, the water or the detergent solution feed from the endoscope may enter the inside of the nozzle and dilutes disinfectant solution inside of the nozzle.

6.6 Loading of endoscopes and accessories177OER-Elite OPERATION MANUALCh.6Attaching the connecting tubes loading to first endoscopeThe OER-Elite is shipped with two sets of four connecting tubes: MAJ-2110, MAJ-2111, MAJ-2112, and MAJ-2113. Check the “List of Compatible Endoscopes/Connecting Tubes <OER-Elite>” to confirm whether these connecting tubes are the correct connecting tubes for the particular model endoscope that you are reprocessing. If the “List of Compatible Endoscopes/Connecting Tubes <OER-Elite>” indicates that a different connecting tube is required, contact Olympus to obtain the necessary connecting tube. Each Olympus endoscope requires a specific connecting tube (or tubes). Do not attempt to reprocess any endoscope without the correct connecting tube.Before using connecting tubes, be sure to inspect the connecting tubes as instructed in Section 5.7, “Inspecting the connecting tubes and leak test air tube”.WARNING• Each connecting tube is supplied with an instruction manual that describes its method of attachment. Follow these instructions to attach the connecting tube to the OER-Elite and the endoscope. Incorrect attachment will result in insufficient reprocessing.• After attaching each connecting tube, visually confirm that there are no irregularities such as kinking, accidental detachment or use of wrong connecting tube and confirm that each connecting tube is firmly attached. If any irregularity is observed, it must be corrected. Otherwise, the reprocessing may be insufficient.• If you are reprocessing two endoscopes in the OER-Elite, and a problem is observed with the connecting tubes on one of the endoscopes, correct the problem and then reprocess both endoscopes again, starting from the beginning.• Disconnect the connecting tubes from the connectors on the reprocessor whenever the tubes are not used for reprocessing. If reprocessing is performed while the unnecessary tubes are connected, the effectiveness of reprocessing may be reduced.• When closing the lid, do not get the connecting tube caught between the reprocessing basin and lid and make sure the endoscopes and the washing case are not touching the lid. Otherwise, the endoscopes, the connecting tubes, the washing case and the reprocessor may be reprocessed insufficiently or get damaged or water leakage from the reprocessing basin may occur.• To confirm the correct connecting tubes are attached to the endoscope, always refer to the instruction manuals for endoscope or the latest “List of Compatible Endoscopes/Connecting Tubes <OER-Elite>”. Using incorrect connecting tubes may result in ineffective reprocessing of endoscopes. If you do not have the latest “List of Compatible Endoscopes/Connecting Tubes <OER-Elite>”, contact Olympus.

6.6 Loading of endoscopes and accessories189OER-Elite OPERATION MANUALCh.6Attaching the Leak test air tube loading to first endoscopeWhen the auto leak test is included in the reprocessing program, connect the leak test air tube.CAUTION• Disconnect the leak test air tube from the connectors on the reprocessor whenever the tubes are not used for leak test. If reprocessing is performed while the unnecessary tubes are connected, fluid may get inside the leak test air tube and could cause it to malfunction. The fluid inside the tube may also damage the endoscope when the leak test is performed next time.• 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 according to Section 5.7, “Inspecting the connecting tubes and 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. If an irregularity is found with the leak test air tube, replace it with a new one and retry the 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.• 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.

6.8 Reprocessing221OER-Elite OPERATION MANUALCh.6Auto leak testThis reprocessor can automatically detect a leak in the endoscope during the reprocessing cycle. The results can be recorded in the reprocessing record. The auto leak test can reduce the mistakes of manual leak test. In addition to this function, also be sure to perform a leak test before performing manual cleaning.Not all endoscopes are capable of auto leak test. For the endoscopes with the auto leak test capability, refer to the “List of Compatible Endoscopes/Connecting Tubes <OER-Elite>”.If the 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.The timing of the auto leak test can be selected at the start of reprocessing or at the end of reprocessing by ALT setting. Refer to Section 6.8, “Reprocessing”.When the reprocessor detects disconnection of the leak test air tube during the reprocessing process, it generates error code [E024] and stops the process.For the related setting changes, refer to Section 4.2, “Auto leak test setting”.At the start of reprocessingWhen warm water is used in manual cleaning, the result of the auto leak test may be erroneous because the internal pressure of endoscope(s) is unstable due to temperature change. If the auto leak test is to be performed at the start of reprocessing, begin the reprocessing process after the endoscope temperature has returned to the room temperature. To return the room temperature, it takes 15 minutes for endoscopes other than ultrasonic endoscopes and 30 minutes for ultrasonic endoscopes. When the auto leak test is performed at the start of reprocessing, the reprocessing time is extended for about 2 minutes. If leak is detected with an endoscope, follow the procedure for leaking scope decontamination on it and contact Olympus for servicing. For details on the leaking scope decontamination, refer to Section 7.15, “Leaking scope decontamination”.At the end of reprocessingWhen the auto leak test is performed at the end of reprocessing, the reprocessing time is extended for about 2 – 7 minutes depending on the type of endoscopes and the atmospheric temperature surrounding the reprocessor.If there is a leak with an endoscope, water may enter the endoscope from the leakage point.
2226.8 ReprocessingOER-Elite OPERATION MANUALCh.6WARNING• When water leak is detected with one endoscope, the other endoscope without water leak might be reprocessed insufficiently. In this case, perform the reprocessing process again.• Avoid exposure to direct sunlight or air conditioning vents. If there is drastic temperature change due to the exposure to direct sunlight or air conditioning, the leak test result may be erroneous.• If the leak test result is “Fail”, do not execute reprocessing process. In this case, perform the leaking scope decontamination process with the leaking endoscope and contact Olympus for servicing. For details on the leaking scope decontamination process, refer to Section 7.15, “Leaking scope decontamination”.CAUTION• Even if the auto leak test is incorporated in the reprocessing program, be sure to perform manual leak test before manual cleaning. If water leaks occur with an endoscope, fluid invasion and damage to the endoscope may occur during manual cleaning.• The touch screen may display error code [E114] (Leaked) due to the effect of the temperature of the endoscope(s). If this happens, execute the auto leak detection again after the endoscope temperature has returned to the room temperature. If error code [E114] is displayed again, perform the leaking scope decontamination process with the leaking endoscope and contact Olympus for servicing. 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.

2627.7 Water line disinfectionOER-Elite OPERATION MANUALCh.7Disinfection of water supply piping is required in the following cases.• Before using this reprocessor for the first time (after loading of the water filter).• Immediately after replacement of water filter.• Whenever bacteria in the water supply piping is identified.• the water line disinfection at least every month.• Before using the reprocessor if it has not been used for more than 14 days.The disinfectant solution stored in the reprocessor is used for disinfection of the water supply piping.WARNING• Before disinfecting the water supply piping, check the concentration of thedisinfectant solution with the test strip, and replace the disinfectant solution if thedisinfectant concentration is below the required level. If this check is not performed,disinfection may be insufficient.• Disinfection of the water supply piping is required each time the water filter isreplaced (i.e., at least once a month). There may be other circumstances wherethis is required, for example a flood or hurricane. Microbiological sampling of theOER-Elite rinse water may indicate disinfection is required.• Disconnect the connecting tubes from the connectors on the reprocessor beforedisinfecting the water supply piping. Otherwise, a jet of disinfectant solution may beoutput from the connecting tubes and leak from a connector such as the gas filtercase connector.• Before handling the disinfectant solution, read the cautions carefully and use it asinstructed. It is especially important to know what to do if the disinfectant solutioncomes in contact with your skin and eyes.• When handling the disinfectant solution, wear personal protective equipment toprevent any disinfectant from getting on your skin and eyes or being inhaled. Avoiddirect physical contact and inhalation of vapors. If any disinfectant solution gets inyour eyes, immediately rinse with a large amount of fresh water and then consult amedical specialist. Personal protective equipment, such as eyewear, face mask,moisture-resistant clothing, and chemical-resistant gloves that fit properly and arelong enough so that your skin and eyes is not exposed. All personal protectiveequipment should be inspected before use and replaced periodically before it isdamaged.7.7 Water line disinfection
7.7 Water line disinfection263OER-Elite OPERATION MANUALCh.7NOTE• Olympus recommends performing microbiological sampling of the OER-Elite rinse water quality right after performing the water supply piping disinfection if the reprocessor has not been used for more than 14 days. For details on sampling rinse water, refer to Section 7.8, “Self-disinfection and water sampling”.• When disinfection of water supply piping is required, Olympus recommends performing it prior to replacement of the disinfectant solution. The disinfectant solution must still meet the MRC using the test strip. After disinfection of water supply piping, drain the disinfectant solution according to the instructions in the instruction manual and the facility policy. Fill the OER-Elite with fresh disinfectant solution prior to proceeding with endoscope reprocessing.• After disinfection of the water supply piping, the quantity and/or concentration of the disinfectant solution might be reduced, which prevents additional reprocessing cycles from being performed. Do not add fresh disinfectant solution to the used disinfectant solution. Drain the disinfectant solution completely and replace with fresh disinfectant solution after disinfection of the water supply piping. It is recommended to perform disinfection of the water supply piping immediately before routine replacement of the disinfectant solution.• Disinfecting the water supply piping also disinfects the water filter and other components in the piping.Workflow of water line disinfection1Checking the MRC level and entering the check result.on page 2642Water line disinfection.on page 266
