 Safety Information 2
WARNING! RISK OF BREATHING DIFFICULTIES
On rare occasions, the outlet filter on the vacuum pump can prematurely fail. If this
occurs, you may see mist or what some users have described as “haze” or “smoke” in
the room where the sterilizer is operating. The chemical composition of the mist is
primarily airborne mineral oil with trace amounts of other compounds. Oil mist
exposure may, theoretically, pose an increased risk to people with certain respiratory
conditions, such as asthma, and they should take special precautions not to be exposed
to the mist. If you observe these conditions, personnel should leave the room as a
precaution and discontinue use of the STERRAD® System until the system is
repaired. Personnel should avoid working in the room until the mist has cleared.

Guidelines for Preparing Items to
Be Sterilized
 Note: All items must be cleaned, rinsed, and thoroughly
dried before being placed in the STERRAD® 100NX®
Sterilizer. Loads containing moisture may cause
cycle cancellations.

Cleaning, Rinsing, and Drying

T
Cleaning and sterilization are two separate processes. Proper cleaning of
instruments and devices is a critical and necessary step prior to sterilization.
 All items including accessories must be thoroughly cleaned, rinsed, and
AF 
dried before loading into the sterilizer.
Carefully inspect all instruments, devices, and accessories for cleanliness
and dryness prior to packaging. If visible soil is present, the item must be
re-cleaned and dried prior to sterilization. If moisture is present, dry the
item thoroughly prior to sterilization.
 Carefully inspect all instruments, devices, and accessories for flaws or
damage prior to packaging. Items with flaws or damage should be
replaced or repaired before using.
R
 Note: Periodic careful inspection of items after repeated
exposure to disinfectant/cleaner/sterilant is necessary,
due to the potential damaging effects of the chemical
agents.

Cleaning is necessary to remove organic and inorganic soil and debris from
D

equipment. This process also removes many microorganisms from the surface
of the items. Sterilization then inactivates all remaining spores and live
microorganisms.
 Clean your devices according to the medical device manufacturers'
instructions. You must remove all blood, tissue, and soil from items using
appropriate detergents, cleansers and/or methods.
 Rinse items thoroughly to remove detergent or cleanser residue. Use
treated water that is of a quality that ensures hard water stains do not
occur. Failure to remove all organic materials or detergents may result in
the formation of light-colored residue on the devices. If residue is visible,
you should clean, rinse, dry, and resterilize the device prior to use.

STERRAD® 100NX® User’s Guide 25

Downloaded from www.Manualslib.com manuals search engine

 3 Load Preparation

 Dry all items thoroughly. An acceptable method for drying is to blow

compressed gas through the lumen until no moisture exits the distal end of
the device. Please ensure that any method used to dry the devices is in
accordance with the manufacturers' instructions for use or contact the
device manufacturer to obtain appropriate and safe procedures. It is
necessary to remove moisture from all parts of the items. Only dry items
should be loaded into the sterilization chamber to prevent cycle
cancellation.
WARNING! POSSIBLE RESIDUAL HYDROGEN PEROXIDE CONTACT!
Failure to ensure that instruments are completely dry before they are processed in
the STERRAD® sterilizer may result in residual hydrogen peroxide being present
on the surface of the load after the cycle is complete. This may cause contact burns

T
when the surface of the load is handled.

 Some complex reusable medical devices may require disassembly for

proper cleaning and sterilization. It is very important that you follow the
AF device manufacturers' recommendations concerning cleaning and
sterilization. In the absence of STERRAD® System-specific instructions,
please contact the relevant medical device manufacturer.

WARNING! POSSIBLE NON-STERILE DEVICE!

Loads containing moisture may result in either a non-sterile device or cycle
cancellation. Wear chemical resistant gloves when handling items from any load
containing moisture.

 Load Preparation 3
EXPRESS Cycle Loading Preparation
 The STERRAD® 100NX® Sterilizer EXPRESS Cycle was validated
using a load weight of 4.9 kg (10.7 lbs) on the bottom shelf only. When
constructing your load, the total weight of the load to be sterilized should
not exceed 4.9 kg (10.7 lbs).

CAUTION: RISK OF DAMAGE TO LOAD OR STERILIZER.

Do not allow metal objects to come into contact with the walls of the chamber, door,
or electrode. Contact with the walls, door, or electrode can cause a cycle cancellation,
and/or damage the item or the sterilizer. Provide at least 25 mm (1 inch) of space
between the load and the electrode.

T
Chemical Indicators
STERRAD® Chemical Indicator Strips and STERRAD® SEALSURE®
AF Chemical Indicator Tape offer a method to verify that the load has been
exposed to hydrogen peroxide in the sterilizer. Chemical indicators are not a
substitute for biological indicators. If you use chemical indicator strips or
chemical indicator tape, follow the Instructions for Use that accompany these
items as you prepare the load.
 Place STERRAD® Chemical Indicator Strips inside trays and
Tyvek® pouches or follow your facility’s procedures.
 Secure all wraps with STERRAD® SEALSURE® Chemical Indicator
R
Tape.
 Do not use chemical indicators or tape designed for other sterilization
processes.

Special Considerations for Flexible Endoscopes

D

Flexible endoscopes are sensitive and complex medical instruments. Read the
flexible endoscope manufacturer’s instructions for each endoscope before
preparation and loading into the sterilizer. Take special care to confirm that
venting caps are placed according to the manufacturer’s instructions. Venting
caps are intended to prevent damage to scopes that are being exposed to a
vacuum, regardless of the sterilant used.
In addition, if you are processing a flexible endoscope containing a water-
resistant “immersion” cap, you must remove the immersion cap prior to
processing. If the immersion cap is not removed prior to processing, it will
damage the scope due to the inability to properly vent.

 3 Load Preparation

FLEX Cycle: A maximum of 2 flexible endoscopes can be processed per

load, with or without silicone mats. Do not add any additional items to the
load.
DUO Cycle: A maximum of 2 flexible endoscopes can be processed per load,
with or without silicone mats. You can also process 1 flexible endoscope with
its light cord and a camera.

CAUTION: RISK OF DAMAGE TO LOAD

Prior to processing flexible endoscopes in the STERRAD® 100NX® Sterilizer, please
contact the medical device manufacturer, or your ASP Customer Representative.

Troubleshooting

 Note: Repairs and adjustments should only be made by ASP

trained and authorized personnel.

T
Most sterilizer operating problems are accompanied by a system message.
These messages are useful in determining the source of the problem.
AF In many cases you can take remedial actions to return the sterilizer to
normal operation. Because load related issues are the most frequent cause
of cycle cancellation, the easiest solution is to repackage the load and restart
the sterilizer when a cycle cancels. Be sure to replace biological and chemical
indicators with new ones. In other cases, the problem may be caused by a
component failure that requires adjustment or repair by an ASP Service
Representative. Call your local ASP Representative for service information.
In the following table are messages that are displayed by the system.
The messages are listed in alphabetical order. Some messages do not
require action on your part and are merely statements of the system status.
Other messages require that you insert a cassette, remove the cassette
R
disposal box, or other such action. The display directs you what steps to
take. If the cycle had cancelled, wear chemical resistant latex, PVC (vinyl)
or nitrile gloves when removing the load.

Running Diagnostics
D

If the sterilizer or the information in the following table directs you to run
diagnostics, remove the load and touch Other Tests from the Diagnostics
menu. If you have received a message containing the word “temperature,”
touch Temperature Tests. (See the section on “Access Levels and Supervisor
Tasks” for information on how to navigate to the Diagnostics menu.) If you
run Diagnostics and the tests show that there are errors, contact your ASP
Representative and report the diagnostic results. If the diagnostic tests pass
with no errors, you can run cycles with your normal load.

 Reports and Files 8
Printed Reports
Every time a cycle is completed, a cycle completion report is printed.
Depending upon how your sterilizer has been configured, the report will
either be a short-format report, a parametric report, or a long-format report.
Each report extracts data from the cycle history record created by the cycle.
The short-format report indicates the cycle status (Passed or Failed), date,
time, operator and load information. The parametric report contains much
more detail than the short report, but is less extensive than the long-format
report. The long-format report includes all of the data in the short report
plus detailed information about each stage of the sterilization cycle.

T
Short Report
The short-format report lists identifying information about the cycle, shows
the cycle status, lists the date and duration of the cycle, and shows operator
AF and load identifying information. The short-format report is useful for record
keeping purposes and providing traceability of sterilized loads.

Parametric Report
The parametric format report shows single-point values for a certain number
of parameters. It is a more confined report than the long printout and contains
a table of all critical parameters and their values. It is only available if an
external printer is attached.
R
Long Report
The long-format report lists detailed information about the cycle, shows the
cycle status, lists the date and duration of the cycle, shows operator and load
D

identifying information, and provides detailed data about the operation of

the sterilizer, including temperatures, pressures, plasma measurements, and
sterilant concentrations throughout the cycle. The long-format report is
useful for detailed cycle quality control and contains valuable diagnostics
information for ASP Service Representatives.
