NOTE
Fluid jet from the water supply/circulation nozzle of this process is gentler than
other processes such as the endoscope reprocessing process. As a result, fluid
spreads on less than half of dome part of the lid whereas the fluid jet of other
process spreads on entire dome part of the lid. This difference is due to use of a
different pump and therefore the gentle fluid flow of this process is adequate.

Microbiological Surveillance
Methods for how to determine microbial level of rinse water
There are several methods for determining the microbial level. For further information on
determining the microbial level, consult other relevant guidelines or standards.
AAMI TIR34: 2014 is the latest edition of this TIR 34, one of the relevant guideline, includes the
information about available methods for how to determine microbial level of rinse water.
Acceptable microbial levels of rinse water
The acceptable microbial levels of rinse water are “bacteria-free”.
Action to be taken if microbial levels exceed acceptable level
If unacceptable bacterial levels are detected, the site should be sampled again to confirm that
unacceptable levels are a consistent finding.
If repeat testing confirms unacceptable levels, then perform decontamination process described
below to reduce the microbial level contamination.
(a) Decontamination process
If the microbial levels continue to exceed acceptable level despite the decontamination process,
an internal problem with the reprocessor or degradation of main water is suspected. In this case,
it is recommended to contact Olympus.
1Perform Self-Disinfection again. For detailed instruction, refer to Section 7.8,
“Self-disinfection and water sampling”.
2Perform Disinfection of the water supply piping. For detailed instruction, refer to
Section 4.20, “Disinfection of the water supply piping” in “Instructions-Installation
Manual”.

OER-Elite OPERATION MANUAL
Ch.7
The 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.
WARNING
When 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.

A scope ID has to be input by an RFID. 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,

OER-Elite OPERATION MANUAL
Ch.7
If water leak of endoscope is detected in a leak test before manual cleaning or an auto leak test before
reprocessing, apply leaking scope decontamination for the endoscope before sending it for servicing
center. By using this function the endoscope can be immersed in the disinfectant solution while
preventing from influx of disinfectant solution into the internal of the endoscope.
In case error code [E115] is displayed during the auto leak test process, perform the manual leak test
and confirm area(s) of the leaking point(s). If a leaking point is found, thoroughly dry the identified
location of the leak on the outer area of the endoscope using alcohol and a clean lint-free cloth.
Carefully apply a piece of electrical tape or other waterproof tape over the location of the leak prior to
immersing the endoscope in detergent solution. Wrapping the tape too tightly may result in damage to
the endoscope. Then perform the Leaking scope decontamination with the endoscope. If error code
[E115] is generated again in Leaking scope decontamination, the leaking point cannot be stopped by
taping, or a leaking point is not found, do not perform this process but contact Olympus. For details,
refer to “Manual decontamination for leaking endoscope” on page 619.
WARNING
• The leaking scope decontamination process is intended to decontaminate a leaking
endoscope before sending it to a servicing center. It does not guarantee the
reprocessing of the endoscope and its accessories after this process. After
completing this process, do not use the endoscope and its accessories in
examination but send it to a servicing center.
• Do not subject an endoscope without leak (correctly functioning endoscope) in this
process.
• Do not perform the Leaking scope decontamination process with auxiliary water
tubes. This process is not capable of high-level disinfection of the auxiliary water
tubes. Even when the auxiliary water tube cleaning setting is activated, do not use
the MAJ-2138. Instead, be sure to use the provided MAJ-2113. Otherwise, the
reprocessing of the auxiliary water tubes may be insufficient.
• When handling the disinfectant solution, wear personal protective equipment to
prevent any disinfectant solution from getting on your skin and eyes or being
inhaled. Avoid direct physical contact and inhalation of vapors. If any disinfectant
solution gets in your eyes, immediately rinse with a large amount of fresh water and
then consult a medical specialist. Wear personal protective equipment, such as
eyewear, face mask, moisture-resistant clothing, and chemical-resistant gloves that
fit properly and are long enough so that your skin and eyes is not exposed. All
personal protective equipment should be inspected before use and replaced
periodically.

WARNING
• Before proceeding to the leaking scope decontamination, always be sure to check
using a test strip that the concentration of the disinfectant solution is no less than
the minimum recommended concentration. If this check is not performed,
decontamination may be insufficient. The disinfectant solution should be replaced
when the concentration falls below the minimum recommended concentration or
the shelf life of the disinfectant solution has expired.
• Disinfectant vapor may still be in the reprocessing basin immediately after the lid is
opened. Wear appropriate personal protective gear to prevent excessive inhalation
of the vapor.
• Before disconnecting a 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 and the endoscope must be reprocessed again.
Otherwise, the reprocessing may insufficient.
• If any irregularity is found with the connection of the connecting tubes, connect
them correctly and retry leaking scope decontamination. Otherwise,
decontamination may be insufficient.
• Be sure to wear sterilized gloves when taking out the decontaminated endoscope.
Otherwise, attaching of dirt on the hand on the endoscope may cause infection.
• This process does not guarantee reprocessing of the endoscope. Pay attention to
in handling the endoscope by wearing protective gear, etc.
CAUTION
• Only one endoscope can be installed in the leaking scope decontamination.
Otherwise, more water may leak into the endoscope during leaking scope
decontamination.
• Always install only one endoscope. If two scopes are installed, water may
penetrate inside them.
NOTE
If water leak is detected in the auto leak test performed according to the setting for
the operation after reprocessing, send the endoscope to repair without performing
this process.

8.2 Replacing the disinfectant solution
OER-Elite OPERATION MANUAL
Ch.8
When the disinfectant solution in the reprocessor is no longer effective, or beyond the specified use
life, drain the disinfectant solution completely and replace with fresh disinfectant solution. Expired
disinfectant solution should be treated as directed in the documents supplied with the disinfectant
solution.
WARNING
• Remove all endoscopes, valves, and connecting tubes from the reprocessing basin
before draining the disinfectant solution. Otherwise, the disinfectant solution cannot
be drained properly, it cannot be mixed sufficiently, and the endoscopes and valves
may be unable to be rinsed sufficiently.
• Before handling the disinfectant solution, read the cautions carefully and use it as
instructed. Be sure that you fully understand what measures need to be taken if you
get any disinfectant solution on your skin and eyes.
• Always use a disinfectant that has been validated by Olympus. High-level
disinfectants that are not validated by Olympus for use in the OER-Elite may be
unsafe and ineffective due to improper dilution, incorrect contact time and
temperature, excessive foaming, inadequate rinse, and therefore may compromise
patient safety. Use of a high-level disinfectant that has not been validated by
Olympus may also damage internal OER-Elite components (e.g., seals, valves,
etc.) and the endoscopes being reprocessed.
• When handling the disinfectant solution, wear appropriate personal protective
equipment to prevent direct contact with your skin and eyes or excessive inhalation
of the vapor. The disinfectant solution and its vapor may adversely affect the
human body. If you get disinfectant solution in your eyes, immediately rinse with a
large quantity of water and then call the doctor. Wear personal protective
equipment, such as eyewear, face mask, moisture-resistant clothing, and
chemical-resistant gloves that fit properly and are long enough so that your skin
and eyes is not exposed. All personal protective equipment should be inspected
before use and replaced periodically before it is damaged.
CAUTION
Expired disinfectant solution should be treated in accordance with the instructions
supplied with the disinfectant solution. It is recommended to treat the waste fluid
properly and to dispose of it according to local wastewater standards defined by
law, or temporarily collect and store the waste fluid and have it treated by a waste
disposal firm.

OER-Elite OPERATION MANUAL
Ch.8
To prevent contamination of the rinse water, the water filter should be replaced every month when the
prefilter is not used or every six months when the prefilter is used. The water filter should also be
replaced whenever an error code indicating water supply insufficiency [E001] is displayed.
To create the record of the replacement of the water filter, select “Replace Water Filter” in the
Replacement of Consumable Items menu.
WARNING
• Replace the water filter in a clean environment. Do not touch the inner side of the
water filter or allow dust to get in it.
• Replace the water filter at least every month and pre-water filter at least every six
month. If the performance of the water filter drops, insufficient elimination of
miscellaneous bacteria in the tap water may cause contamination of the instrument
and scopes and make the reprocessing insufficient.
• After replacing the water filter, be sure to perform the water line disinfection to
prevent the growth of water-borne microorganisms. Failure to perform this
operation could result in contamination of the reprocessor piping and ineffective
reprocessing of the endoscope.
• Always be sure to attach the specified water filter. Otherwise, water-borne
microorganisms and particulates in the water may contaminate the reprocessor
piping and prevent effective reprocessing of the endoscope.
• Before handling the disinfectant solution, read the SDS and instructions for use of
the disinfectant solution carefully, get fully accustomed to the contents, and use the
disinfectant solution as instructed. Be sure to fully understand what to do if the
disinfectant solution comes in contact with your skin and eyes.
• When handling the disinfectant solution, wear personal protective equipment to
prevent any disinfectant from getting on your skin and eyes or being inhaled. Avoid
direct physical contact and inhalation of vapors. If any disinfectant solution gets in
your eyes, immediately rinse with a large amount of fresh water and then consult a
medical specialist. Wear personal protective equipment, such as eyewear, face
mask, moisture-resistant clothing, and chemical-resistant gloves that fit properly
and are long enough so that your skin and eyes is not exposed. All personal
protective equipment should be inspected before use and replaced periodically
before it is damaged.

CAUTION
• Hold the water filter wrench at a point below the projection on the grip. If you hold it
at a point closer to the water filter housing connector than the projection, you might
catch your finger in the reprocessor.
• If air gets in the water filter housing, it may extend the process time. In case of an
irregularity such as extension of the process time or lack of water supply, drain the
air as described in “Draining air in the water filter housing” on page 389.
• Do not to drop the removed water filter housing to avoid damaging the connector
below the water filter housing. Make sure that the O-ring at the head of the water
filter housing is free of irregularities such as cracks, breaks, rips, scratches, or
stains. Water leakage may result if the O-ring is not attached or is abnormal.
NOTE
• When replacing water filter, select the “Replace water filter” in the Replacement of
Consumable Items screen. Otherwise, the record of the replacement of the water
filter will not be created.
• Filter life varies depending on a number of factors including incoming water quality
and use volume.
• Using at least a prefilter (0.45 micron or less) can extend the life of the water filter.
If the prefilter is properly installed, the water filter and the prefilter should be
replaced at least once every 6 months. For information on the water pre-filtration
system, contact Olympus.
• 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. Except for the case of performing water line disinfection with
fresh new disinfectant solution, do not add fresh disinfectant solution to increase
the volume of the disinfectant solution in the OER-Elite. 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.

Disinfecting the water line
WARNING
• Before disinfecting the water supply piping, check the concentration of the
disinfectant solution with the test strip, and replace the disinfectant solution if the
disinfectant 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 is
replaced (i.e., at least once a month). There may be other circumstances where
this is required, for example a flood or hurricane. Microbiological sampling of the
OER-Elite rinse water may indicate disinfection is required.
• Disconnect the connecting tubes from the connectors on the reprocessor before
disinfecting the water supply piping. Otherwise, a jet of disinfectant solution may be
output from the connecting tubes and leak from a connector such as the gas filter
case connector.
1Place as container with a capacity of 2 L or more in front of the reprocessor.

Ch.8
Replace the air filter every month.
To create the record of the replacement of the air filter, select “Replace Air Filter” in the Replacement of
Consumable Items menu.
WARNING
• Always be sure to attach the specified air filter. Otherwise, the air may contaminate
the reprocessor piping and/or the scope and prevent effective reprocessing.
• Replace the air filter at least every month. If the performance of the air filter drops,
insufficient elimination of miscellaneous bacteria in air may cause contamination of
the instrument and scopes and make the reprocessing insufficient.
NOTE
When the air filter counter setting is activated, the filter replacement indicator can
be displayed on the top right of the touch screen and on the “Replace Air Filter”
button on the Replacement of Consumable Items menu when the counter setting
value is reached.
