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.

EVIS EXERA GIF/CF/PCF TYPE 160 Series REPROCESSING MANUAL
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.
