1.2 Signal words
The following signal words are used throughout this manual:
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury. It may also
be used to alert against unsafe practices or potential
equipment damage.
Indicates additional helpful information.
1.3 Precautions
• Failure to properly clean and high-level disinfect or sterilize
endoscopic equipment after each examination can
compromise patient safety. To minimize the risk of
transmitting diseases from one patient to another, after each
examination the endoscope must undergo thorough manual
cleaning followed by high-level disinfection or sterilization.
• ALL channels of the endoscope, including auxiliary water
channel where fitted, MUST be cleaned and high-level
disinfected or sterilized during EVERY reprocessing cycle,
even if the channels were not used during the previous
patient procedure. Otherwise, insufficient cleaning and
disinfection or sterilization of the endoscope may pose an
infection control risk to the patient and/or operators
performing the next procedure with the endoscope.
• If the endoscope is not cleaned meticulously, effective
disinfection or sterilization may not be possible. Clean the
endoscope and accessories thoroughly before disinfection or
sterilization to remove microorganisms or organic material
that could reduce the efficacy of disinfection or sterilization.

Chapter 1 General Policy
EVIS EXERA GIF/CF/PCF TYPE 160 Series REPROCESSING MANUAL
• Olympus confirms validation of the endoscope reprocessors
recommended by Olympus only. If using endoscope
reprocessor that are not recommended by Olympus, the
endoscope reprocessor manufacturers are responsible for
validation of the endoscope reprocessor with the endoscope
models listed in its intended use statement. If using an
endoscope reprocessor, confirm that it is capable of
reprocessing endoscope including all channels. If there are
channels and/or other parts which cannot be cleaned and
high-level disinfected by the endoscope reprocessor, have to
undergo manual cleaning and high-level disinfection or
sterilization as described in Chapter 3, “Cleaning,
Disinfection and Sterilization Procedures” after using the
endoscope reprocessor. Otherwise, insufficient cleaning and
disinfection or sterilization of the endoscope may pose an
infection control risk to the patient and/or operators
performing the next procedure with the endoscope. If you are
uncertain as to the ability of your endoscope reprocessor to
clean and high-level disinfect endoscope including all
channels, contact the endoscope reprocessor supplier for
specific instructions and/or connectors.
• Patient debris and reprocessing chemicals are hazardous.
Wear personal protective equipment to guard against
dangerous chemicals and potentially infectious material.
During cleaning and disinfection or sterilization, wear
appropriate personal protective equipment, such as eye
wear, face mask, moisture-resistant clothing and
chemical-resistant gloves that fit properly and are long
enough so that your skin is not exposed. Always remove
contaminated personal protective equipment before leaving
the reprocessing area.
• Thoroughly rinse off the disinfectant solution. Rinse the
external surfaces of the endoscope, all channels and
cleaning equipment thoroughly with clean water to remove
any disinfectant solution residue.
• The disinfection/sterilization room must be adequately
ventilated. Adequate ventilation protects against the buildup
of toxic chemical fumes.
• Store alcohol in an air-tight container. Alcohol stored in an
open container is a fire hazard and will lose its efficacy due to
evaporation.

Endo-therapy accessories which are marked by the words
“AUTOCLAVE” or “AUTOCLAVABLE”, or accessories with a
green model reference label, are compatible with
autoclaving.
2.2 Detergent solution
Use a medical-grade, low-foaming, neutral pH detergent or enzymatic detergent
and follow the manufacturer’s dilution and temperature recommendations.
Contact Olympus for the names of specific brands that have been tested for
compatibility with the endoscope. Do not reuse detergent solutions.
Excessive detergent foaming can prevent fluid from
adequately contacting internal lumens (e.g. channels).
2.3 Disinfectant solution
In the U.S., agents used to achieve high-level disinfection are defined as liquid
chemical germicides registered with the U.S. Food and Drug Administration as
“sterilant/disinfectants” which are used according to the time, temperature and
dilution recommended by the disinfectant manufacturer for achieving high-level
disinfection. These conditions usually coincide with those recommended by the
disinfectant manufacturer for 100% kill of mycobacterium tuberculosis.
In general, 2.0 – 3.5% glutaraldehyde solutions, when used according to the
manufacturer’s instructions for achieving high-level disinfection, are compatible
with Olympus endoscopes. Contact Olympus for the names of specific brands
that have been tested for compatibility with the endoscope.
If the disinfectant solution is reused, routinely check its efficacy with a test strip
recommended by the manufacturer. Do not use solutions beyond their expiration
date.
Alcohol is not a sterilant or high-level disinfectant.

EVIS EXERA GIF/CF/PCF TYPE 160 Series REPROCESSING MANUAL
2.4 Rinsing water
Once removed from disinfectant solution, the instrument must be thoroughly
rinsed with sterile water to remove any disinfectant residue. If sterile water is not
available, clean potable tap water or water which has been processed (e.g.
filtered) to improve its microbiological quality may be used.
When non-sterile water is used after disinfection, wipe the endoscope and flush
the channels with 70% ethyl or isopropyl alcohol, then air-dry all internal
channels to inhibit the growth of residual bacteria. Do not reuse rinsing water.
2.5 ETO gas sterilization
This instrument and other accessories listed as compatible with ethylene oxide

organic debris will begin to solidify and it may be difficult to
effectively reprocess the endoscope.
• Turn the endoscope’s illumination OFF immediately after the
examination. The temperature at the distal end of an
illuminated endoscope may exceed 41C (106F) and reach
50C (122F) due to intense endoscopic illumination.
Surface temperature above 41C (106F) may cause burns.
Preclean the endoscope at the bedside in the procedure room immediately after
the procedure.

Performing the leakage test
• During leakage testing, a continuous series of bubbles
emerging from a location on the endoscope indicates a leak
at that location. This means that water will be able to
penetrate the inside of the endoscope. If you locate a leak,
remove the endoscope from the water and contact Olympus.
• Never connect or disconnect the water-resistant cap(s) or the
leakage tester’s connector cap while immersed. Doing so
could allow water to enter the endoscope and equipment
damage can result.
• Rotate the leakage tester’s connector cap until it stops. If it is
not fully and properly attached, the endoscope’s interior will
not be pressurized and accurate leakage testing will be
impossible.
• When attaching the leakage tester’s connector cap to the
water-resistant cap’s venting connector, make sure that the
inside of the leakage tester’s connector cap and the outside
of the water-resistant cap’s venting connector are thoroughly
dry. Water remaining on either component may penetrate the
inside of the water-resistant cap (MH-553) and could cause
endoscope malfunction.
• Detaching the leakage tester’s connector cap from the
venting connector while the leakage tester is still connected
to the light source will not allow the endoscope to
depressurize properly. This may damage the endoscope.
When the leakage tester connector is in place, the covering
of the bending section will expand as the air pressure inside
the endoscope increases. This is normal.
1. Fill a basin with clean water. Use a basin which is at least 40 cm by 40 cm
(16” by 16”) in size and deep enough to allow the endoscope to be
completely immersed.
2. Insert the leakage tester connector into the output socket of the
maintenance unit or the light source and turn the maintenance unit or the
light source ON. Set the light source’s airflow regulator switch to “HIGH” or
“3”.
3. Confirm that the leakage tester is emitting air by gently depressing the pin
located inside the leakage tester’s connector cap.
Page 40

4. Connect the leakage tester’s connector cap to the venting connector of the
water-resistant cap (MH-553) (see Figures 3.19 or 3.20).
Figure 3.19
Figure 3.20
5. With the leakage tester connected, immerse the endoscope in water and
observe for approximately 30 seconds while angulating the bending section.
Confirm that there is no location on the endoscope from which a continuous
series of bubbles emerges.
6. Remove the endoscope from the basin with the leakage tester attached.
7. Turn the maintenance unit or the light source OFF.
8. Disconnect the leakage tester from the maintenance unit or the light source.

Brushing the channels
• To avoid splattering detergent solution when the channel
cleaning brush is pulled out, keep the endoscope
submerged.
• The channel cleaning brush is a consumable item that is
subject to wear. If the brush head is bent or kinked during
use, the brush may come off. Confirm that the brush is free
from any damages or irregularities before and after each use.
Should a part of the brush head come off, immediately
retrieve it and carefully confirm that no parts are left inside
the channel of the endoscope by passing a new cleaning
brush or other endo-therapy accessories through it. Any part
left in the channel, may drop into the patient during the
procedure. Depending on the location, the missing part may
not be recoverable by passing a new brush or other
endo-therapy accessory through the channel. In this case,
contact Olympus.
Withdraw the channel cleaning brush from the suction
channel gently, ensuring its shaft does not rub against the
external opening of the suction cylinder, as this may damage
the brush and may wear a groove in the opening, leading to
impaired suction and liquid leakage.
While the endoscope is submerged, brush the instrument and suction channels,
suction cylinder and instrument channel port according to the following
procedures (see Figure 3.22).

Chapter 4 Cleaning and Disinfection
Equipment
The endoscope is compatible with some endoscope reprocessors
recommended by Olympus. Refer to the instruction manual of endoscope
reprocessor for details on operation.
• Thoroughly clean the endoscope as described in Chapter 3,
“Cleaning, Disinfection and Sterilization Procedures” before
cleaning and disinfection of an endoscope in an endoscope
reprocessor. If the endoscope reprocessor is used with an
endoscope with a large amount of debris attached to it,
cleaning and disinfection may pose an infection-control risk
to the patients and/or operators who perform the next
procedure with it. Note that cleaning of the endoscope
becomes difficult if debris is allowed to solidify because of a
delay before cleaning following the procedure. Refer to the
instruction manual of endoscope reprocessor for details.
• Olympus confirms validation of the endoscope reprocessors
recommended by Olympus only. If using endoscope
reprocessor that are not recommended by Olympus, the
endoscope reprocessor manufacturers are responsible for
validation of the endoscope reprocessor with the endoscope
models listed in its intended use statement. If using an
endoscope reprocessor, confirm that it is capable of
reprocessing endoscope including all channels. If there are
channels and/or other parts which cannot be cleaned and
high-level disinfected by the endoscope reprocessor, have to
undergo manual cleaning and high-level disinfection or
sterilization as described in Chapter 3, “Cleaning,
Disinfection and Sterilization Procedures” after using the
endoscope reprocessor. Otherwise, insufficient cleaning and
disinfection or sterilization of the endoscope may pose an
infection control risk to the patient and/or operators
performing the next procedure with the endoscope. If you are
uncertain as to the ability of your endoscope reprocessor to
clean and high-level disinfect endoscope including all
channels, contact the endoscope reprocessor supplier for
specific instructions and/or connectors.

• Use connectors special to each model when cleaning and
disinfecting the endoscope with the endoscope reprocessor.
Otherwise, insufficient cleaning and disinfection or
sterilization of the endoscope may pose an infection control
risk to the patient and/or operators performing the next
procedure with the endoscope. The applicable connectors for
each endoscope model should be listed in the automated
endoscope reprocessor instruction manual. If your
endoscope model is not listed in this table, please contact the

EVIS EXERA GIF/CF/PCF TYPE 160 Series REPROCESSING MANUAL
Chapter 5 Storage and Disposal
5.1 Storage
• The storage cabinet must be clean, dry, well ventilated and
maintained at ambient temperature. Storing the endoscope in
direct sunlight, at high temperatures, in high humidity or
exposed to X-rays and ultraviolet-rays may damage the
endoscope or present an infection control risk.
• Prior to storage, detach all removable parts from the
endoscope. It will allow air to circulate through the internal
lumens of the endoscope and will assist drying.
• Prior to storage, uncap the auxiliary water inlet. This will
allow air to circulate through the internal lumen of the
endoscope and will assist drying (for endoscopes with
auxiliary water feeding only).
• Do not store the endoscope in the carrying case. Use the
carrying case only for shipping the endoscope. Routinely
storing the endoscope in a humid, non-ventilated
environment such as the carrying case may present an
infection control risk.
• When storing an endoscope that has the flexibility
adjustment mechanism, make sure that the insertion tube is
set to the softest condition (indicated by the “” mark on the
flexibility adjustment ring). If the endoscope is stored while
