OWNER’S MANUAL
SECTION 1
Before You Begin
There are a number of conditions that can affect the operation of your sterilizer. By paying
close attention to these details, you will greatly reduce the likelihood of problems.
1.1. Installation: Please make sure that your Anprolene sterilizer is installed cor-
rectly. Full installation instructions can be found in Appendix B, starting on page
46. Please call our Customer Service Department if you have installation questions
not covered in this section.
1.2. Environmental Factors: Your Anprolene sterilizer is designed to operate at
room temperature (68°F/20°C to 91°F/33°C ). Please pay close attention to the
following factors:
a. Temperature: Ethylene Oxide (EtO) is sensitive to temperature and
becomes less effective at lower temperatures. Make sure that the room
where the sterilizer is installed maintains a temperature between 68°F/20°C
and 91°F/33°C for the full duration of the sterilization cycle.
b. Humidity: Anprolene sterilization requires at least 35% relative humidity
(RH). In low humidity areas, or during the winter months when the
humidity level drops, an Andersen Humidichip® may be necessary to
achieve and/or maintain the proper humidity level in the sterilization liner
bag. Please refer to Section 4, beginning on page 17, for more information
on humidity and pre-humidification.
1.3. Preparing Items for Sterilization: Materials to be sterilized by all Ethylene
Oxide sterilizers, including Anprolene, must be meticulously cleaned and dried.
Coatings of dried proteins such as pus, blood or feces protect microorganisms and
slow the sterilization process. Precautions must always be taken before
sterilization with Anprolene. To prepare items for sterilization, please include the
following steps:
a. Disassemble - Anprolene is a highly diffusible gas sterilant; nevertheless,
occlusive caps, plugs and stylets must be removed from instruments so that
the gas can penetrate freely. Hollow bore needles and plastic or rubber tubing
must be open and free from stylets and plugs. Syringes must be packaged
with the plungers removed.
b. Wash - Scrub the disassembled instruments in detergent and water to the
most critical standard of cleanliness possible. We recommend the use of an
enzymatic cleaner such as Andersen Products’ AN2281 Surgical Instrument
Enzymatic Detergent, which may be used with most materials.
c. Dry - Water on instruments at the time of exposure to Anprolene may react
with the gas and reduce its effectiveness. Make sure that items to be steril-
ized are physically dry before wrapping and processing. Towel drying or
drain drying is sufficient. CAUTION: Do not use hot air to dry.
d. Wrap - All items to be sterilized must be wrapped in cloth, paper or plastic in
the manner conventional for steam sterilization, or in Andersen Seal and
Peel® Packaging.

4.1 Humidity and Pre-humidification
4.2 Abridged Illustrated Instructions
4.3 Key Operator Study Guide
4.1. Humidity and Pre-humidification.
It has been demonstrated repeatedly that some microorganisms are made very resistant to
Ethylene Oxide sterilization systems by desiccation, which is exposure to very low relative
humidity.
As a result, humidity is a very important part of the Ethylene Oxide sterilization cycle. Items
that can be washed in water and towel or air dried will not need pre-humidification.
Items that may be damaged by immersion in water or a sterilization load that contains a large
amount of material that will absorb water (dry paper and cloth) will need pre-humidification.
Process for Pre-Humidification Using an Anprolene Sterilization Liner Bag
a. Items that cannot be immersed in water should be disassembled and wrapped in
the usual way.
b. Place the prepared items along with a Humidichip® inside a sterilization liner
bag. Using a twist tie or Velcro® strap, securely close the neck of the bag.
c. Leave the items in the bag for a minimum of four hours at a temperature of
68°F /20°C or higher. Pre-humidification may take place outside the sterilizer
cabinet. Take caution not to rip or puncture the sterilization liner bag.
During the sterilization cycle, use a Humidichip to ensure a minimum of 35% Relative Hu-
midity inside the sterilization liner bag. Items that did not need pre-humidification can be
added to the sterilization liner bag, along with the appropriate controls such as Dosimeter®,
Steritest®, or other Biological Indicators. If there is any question as to the integrity of the
sterilization liner bag, use a new liner bag for the sterilization cycle.

OWNER’S MANUAL
4.2 ABRIDGED ILLUSTRATED INSTRUCTIONS
HOW ANPROLENE WORKS
1. The glass ampoule contains liquid Ethylene Oxide (EtO) and
an inert solid stabilizer. The ampoule is scored at the neck for
easy opening.
2. A plastic/fabric break shield surrounds the ampoule.
The ampoule and shield are sealed inside a plastic gas-
release bag, which should never be opened.
IMPORTANT! Push the ampoule to the center of the
gas release bag before activating
3. After the gas release bag is placed inside of the sterilization
liner bag and it is secured to the purge bobbin, the sterilization
bag is then vacuumed down. To release pure EtO gas, manually
snap off the top of the ampoule by manipulating it through the
walls of the sterilization liner bag. The plastic/fabric shield
prevents the broken glass of the opened ampoule from punctur-
ing the gas-release bag.
4. The liquid EtO then boils, releasing 100% EtO gas
within the gas-release bag, leaving residual deposits of
the previously dissolved inert solid stabilizer.
5. Since the walls of the gas-release bag are permeable only to
EtO gas and not the inert solid stabilizer, only the 100% pure
EtO gas diffuses through the walls of the gas-release bag and
into the liner bag.
6. EtO possesses great kinetic energy, which causes the
gas molecules to spread out to every cubic centimeter of
the liner bag by their own velocity.
21
OWNER’S MANUAL
4.2 ABRIDGED ILLUSTRATED INSTRUCTIONS
HOW ANPROLENE WORKS
7. EtO gas readily passes through cloth, paper, and Seal
and Peel® Packaging to reach the items to be sterilized.
8. The walls of the sterilization bag are also porous to EtO
gas. As the concentration of EtO gas in the liner bag is
increased by gas diffusing from the gas-release bag, the EtO
molecules also diffuse through the walls of the liner bag and
into the sterilization cabinet.
9. The EtO molecules diffusing from the liner bag into the
sterilization cabinet are then evacuated to the abator, if installed.
Any remaining effluent is then vented to the outside atmosphere
by the sterilizer’s ventilation system.
10. For about three hours there are more EtO molecules
released into the liner bag than are released by the liner bag
into the sterilizer. Then the rates are similar for three hours.
Finally, the liquid Anprolene in the gas-release bag is
exhausted. EtO molecules gradually diffuse into the sterilizer
for the remainder of the cycle.
11. At 12 hours, all items are sterile, and the residual gas in the
liner bag is small. The additional two-hour purge cycle is used
to remove remaining residual EtO from the liner bag before the
container may be opened.
12. Gas-absorbent materials, like plastic and rubber, are
aired in their protective wrapping before use. The EtO
gas absorbed by plastic or rubber readily escapes through
cloth, paper, or Seal and Peel® Packaging.

OWNER’S MANUAL
Thank you for using the Anprolene® sterilization system.
The active ingredient in Anprolene is ethylene oxide (EtO or EO), a chemical that can be hazardous
if not handled properly. To ensure that you fully understand the safe operation of your sterilizer, we
strongly encourage you to take advantage of our Key Operator certification program.
To begin Key Operator training, please read through this study guide thoroughly. If you do not
understand any of the information in the guide, please call Andersen Customer Service for
assistance. Once you are familiar with the study guide, you can call us at (800) 523-1276 to
schedule a test.
The test will take approximately 20 minutes. The Key Operator test is also an excellent opportunity
to ask your Andersen Representative any questions you may have about your Anprolene system or
ethylene oxide.
When you successfully complete the test, you will receive a certificate and a registered key ring.
We look forward to hearing from you.
Key Operator training is free of charge for the lifetime of your sterilizer. Please have all new
operators of your Anprolene sterilizer contact us for training before they use the system.
4.3 Key Operator Study Guide:
AN74I / IX Anprolene® Sterilizer

OWNER’S MANUAL
A. Environmental Considerations
1) Temperature
• Store your Anprolene gas refill kits in a cool, secure area. We recommend storage
below 72°F (22.2°C).
• The sterilizer must be used in an area where the temperature is not less than 68ºF
(20°C) or more than 91ºF (33°C). This temperature range must be maintained
during the entire sterilization cycle.
EO FACTS: At sea level, ethylene oxide is a liquid below 51
°
F (10.6.
°
C).
Above 51
°
F, EO begins to boil and converts into a gas. EO does not become an
effective sterilant until 68
°
F (20
°
C) Make sure that the room where your
Anprolene sterilizer is installed remains above 68
°
F during the entire 12-hour
sterilization cycle. This is especially important during the winter months!
2) Humidity
• Humidity is very important to the Anprolene process. Relative Humidity (RH) must
be at least 35% in the room where item preparation and sterilization take place.
Spores that might be on the instruments may become very dry and resistant to
Anprolene if the RH is below 35%.
• The simplest way to humidify items is to wash them.
• It is necessary to humidify items which cannot be washed by enclosing them in a
plastic bag with an Andersen Humidichip® or a damp sponge for four hours prior to
sterilization at a temperature greater than 68 °F (20 °C)
B. Preparing Items for Sterilization
Four basic steps must always be followed when preparing items for sterilization:
1) Disassemble
2) Wash
3) Dry
4) Wrap
1) Disassemble
Items containing removable parts, such as syringes, must be taken apart before wash-
ing, drying, and wrapping them to allow the Anprolene an unobstructed path.
WARNING!: Instruments which contain batteries should be taken apart and the
batteries removed and wrapped separately to protect against a spark occurring and
igniting the ethylene oxide gas.
2) Wash
Items must be washed surgically clean prior to sterilization. For cleaning, we recom-
mend using an enzymatic detergent such as Andersen’s Sterizyme (AN2281).
24
OWNER’S MANUAL
3) Dry
Two accepted ways to dry any item prior to sterilization with Anprolene are:
1. Towel drying
2. Drain drying (air drying).
WARNING!: Heat or hot air should never be used to dry an item prior to steriliz-
ing it with Anprolene because it will dehydrate or dry out bacteria spores making
them more resistant to the ethylene oxide gas.
WARNING!: Any water left on items may react with ethylene oxide, reducing its
efficacy. Please air dry instruments thoroughly.
4) Wrap
The following types of wrapping material are recommended for use with Anprolene:
1. Andersen Seal and Peel® Packaging (which is airtight and waterproof and greatly
extends the shelf life when heat sealed at both ends)
2. Cloth (like CSR wrap) has an estimated sterile shelf life of 30 days
3. Paper (self-seal pouches) has a shelf life of 30 days
4. Tyvek-paper pouches
☺HINT: Exposure indicators such as the Andersen AN85 or AN86 will turn color in
the presence of EO, helping to later identify items that have been sterilized.
C. Sterilization Cycle
1) Preparing the Sterilization Liner Bag
1. Place prepared items in a new sterilization liner bag.
WARNING!: Do not reuse sterilization liner bags. Even a tiny pinhole in a sterili-
zation liner bag can allow gas to escape and cause cycle failure!
WARNING!: Do not sterilize liquids, foods or drugs in the Anprolene sterilizer. If
you have any questions about whether an item may be sterilized using Anprolene,
please call Andersen Customer Service.
2. Insert appropriate controls such as a Dosimeter (chemical indicator) or a Steritest®
(biological & chemical indicator) into the least accessible part of the sterilization
liner bag. Add a Humidichip® if appropriate.
3. Unroll the gas release bag containing the gas ampoule and, without opening it, gently
move the ampoule to the center of the gas release bag. Place it on top of the items in
the sterilization liner bag where it will be easy to break.
25
OWNER’S MANUAL
4. Insert the purge tube into the sterilization liner bag with the aluminum bobbin and
quick release fitting at the open end. Place the black Velcro® strap around the
sterilization liner bag and the bobbin of the purge tube, and pull it snug though its
loop to close the sterilization liner bag. The strap must secure the sterilization liner
bag tightly around the aluminum bobbin to keep gas from escaping.
5. Connect the quick release connector to the purge tube, if it is not already connected.
☺HINT: The sterilization liner bag may be loaded and sealed away from the steri-
lizer cabinet, and connected to the purge tube once you are ready to start a cycle.
2) Starting the Cycle
1. Make sure the AN74 i/ix power cord is connected. Press the right side of the power
switch located on the right rear of the cabinet. Wait to see the ‘AN74 I
ANPROLENE STERILIZER’ and the ‘START’ message to appear on the cabinet
display.
2. Push the button to the right of START.
3. Wait for the SELF TEST and number of elapsed PUMP HOURS to appear. (If above
18,000 hours, call Andersen for service.)
4. Press the button to the right of the PURGE message on the display and wait for the
time to count down from 1 minute 30 seconds to ‘00:00:00’. The sterilization liner
bag should compress as excess air is removed.
5. When the display indicates “BREAK AMPOULE,” carefully, so as not to puncture
the sterilization liner bag, grasp the ampoule through the sterilization liner bag and
activate it by snapping off the top.
3) Selecting Cycle Length
1. Close the door.
2. Lock the sterilizer and remove the key.
3. SELECT CYCLE LENGTH. (Right button = 12 Hour, Left button = 24 Hour)
WARNING: The usual Anprolene sterilization cycle is 12 hours, plus a 2-hour
purge cycle. When sterilizing lengths of tubing 3 feet (91.4 cm) or longer, or a full
load of gas absorbent items, it may be necessary to increase the cycle time to 24
hours with the ‘24 HOUR CYCLE’ button and to use two ampoules.
4. If an electronic beep sounds, it is an alert that 5 seconds have elapsed and the
AN 74 i/ix is awaiting a 12/24 hour cycle time selection.
5. Log sterilization data if required.
WARNING: Never interrupt a cycle once the gas ampoule has been activated. An
alarm will sound if the door is opened during the cycle.
26
OWNER’S MANUAL
4) Unloading the Sterilizer and Determining Sterility
1. Remove the sterilized items only after the sterilization cycle and 2-hour purge cycle
have been completed and the display indicates UNLOAD STERILIZER. The
sterilizer will continue to aerate items that are not removed immediately. A count-up
timer on the display will indicate the time that has lapsed since the final 2-hour purge
cycle ended.
☺HINT: To unload the sterilization liner bag away from the sterilizer, simply de-
tach the purge probe hose from the bag using the quick release fitting at the base of
the purge probe.
2. Close the sterilizer door and press EXIT to turn off the AN74 i/ix.
3. Unload the liner bag and check the sterility (chemical &/or biological) indicators.
• Steritest provides an immediate indication of the success of the cycle (via the
Dosimeter), and later proves sterility by showing that active spores have been
killed. (Spores will require at least 48 hours of incubation to provide results.)
• The Dosimeter shows whether time, temperature and gas concentration
parameters have been met. It provides an immediate chemical indication that the
cycle was successful. Dosimeters should not be used in place of biological
indicators to prove sterility.
• Chemical exposure indicators, such as the AN85 or AN86, do not prove
sterilization. They only change color to show that the items have been exposed to
ethylene oxide.
4. Spent ampoule may be disposed of in regular trash.
☺HINT: While you may not reuse sterilization liner bags, they make great heavy-
duty trash bags!
D. Aeration
• The cabinet ventilator should be running during the entire sterilization cycle to
prevent personnel from being exposed to more than the OSHA permitted levels of
ethylene oxide. [1.0 ppm (parts per million) over an 8 hour time weighted average
(TWA)] Do not remove items before the full 2-hour purge cycle. Aeration should
take place in a well-ventilated area that provides at least 10 fresh air exchanges
per hour so that high concentrations of gas will not build up while aerating. The
purge cycle is designed to aerate most products sufficiently to meet the short-term
exposure level (STEL) of 5.0 ppm for the 15-minutes (while unloading the liner
bag).
• Metal and glass do not require additional aeration. However, items made of gas
absorbent material must be aerated at a minimum room temperature of 68° F (20°
C) for at least 24 hours prior to use. Any ethylene oxide retained in an item could
cause a serious chemical contact burn to the patient.
27
OWNER’S MANUAL
☺HINT: The AN74 i/ix can be used for extended aeration. A count-up timer will keep
track of the time that has passed since the standard cycle was completed. After the
regular cycle is finished, the sterilizer will continue to ventilate and purge the liner bag
until: (1) the door is opened; and (2) the EXIT button is pressed. This will turn off both
pumps and end the cycle. If the door is opened and closed and the EXIT button is not
pressed, the two pumps will continue to ventilate and purge the liner bag and cabinet.
• Extended aeration can also take place outside of the sterilizer. In this case, aeration
should take place in a well-ventilated area that provides at least 10 fresh air
exchanges per hour so that high concentrations of gas will not build up while
aerating.
E. Safety Precautions
1) Ethylene Oxide Safety
• Sterilization liner bags should never be reused because they may have a puncture or
tear.
• DANGER! Do not allow open flame or sparks near the sterilizer during the
sterilization cycle because ethylene oxide gas is highly flammable in concentrations
above 3.0% (30,000 ppm).
• The 12 and 24-hour sterilization cycles both end with a 2-hour purge cycle, which
flushes fresh air around the products in the sterilization load.
• The sterilization liner bag must be purged for 2 hours before the sterilized items are
removed to prevent the operator from being exposed to more than the OSHA
permitted level of 5.0 ppm in a 15-minute time period (STEL) while the sterilizer is
being unloaded.
• Personnel exposure to ethylene oxide can be monitored by using the personal
exposure badges, such as the Andersen AN93 AirScan® Badges. The AN93 AirScan
Kit has both STEL and TWA badges. EO exposure levels should be checked upon
installation of the sterilizer. We recommend that exposure testing be performed on an
annual basis.
• CAUTION. If you come in contact with liquid Anprolene, you should immediately
wash the affected area with water thoroughly for at least 15 minutes and obtain
medical attention.
2) Malfunctions and Power Failures
• In the event of a purge pump failure, the vent pump will continue to ventilate the
interior of the cabinet, exhausting gas as it diffuses through the liner bag. A PURGE
PUMP FAILURE error message will be displayed, and the sterilizer will add 24
hours of aeration before the display indicates that you may remove your products. (If
this happens, please call Customer Service for assistance.)
• In the event of a vent pump failure, the cycle will be aborted, and the purge pump
will evacuate the liner bag of any remaining gas. (If this happens, please call
Customer Service for assistance.)
28
OWNER’S MANUAL
• If a power outage occurs during any part of the cycle, the sterilizer is equipped with a
battery back up on the circuit board that will keep track of elapsed cycle time. When
power is restored, the cycle will continue. Do not open the door of the sterilizer until
power is restored and the vent/purge systems have removed any residual gas from
the liner bag.
☺HINT: In the case of any sterilizer malfunction or power failure, you can determine
whether sterilization was achieved by examining the Steritest biological indicator
included in the load.
3) Reasons for locking the Anprolene sterilizer:
1. To protect the contents from spark or flame.
2. To protect the liner bag from puncture.
3. To ensure the Anprolene sterilizer exhausts the ethylene oxide through the
ventilation system and abator, if installed, to the outside.
Note: No other container or sterilizer can be used with Anprolene sterilizing gas.
4) Reasons why the gas release bag containing the ampoule should never be opened:
1. To prevent the liquid ethylene oxide from coming in contact with the user or the
items to be sterilized.
2. To prevent the gas from escaping too quickly to achieve sterilization.

OWNER’S MANUAL
Pre-Cycle Error Messages (Before the ampoule is broken): The self test portion
of the cycle begins when the START button is pressed and ends after the initial purg-
ing of the sterilization liner bag. Ethylene Oxide has not been released into the ster-
ilization liner bag during the self test. Therefore, it is safe to remove the sterilization
liner bag and its contents from the machine if needed. The self test screen is shown
below.
If you see this screen, the controller is indicating that the ventilation sensor, purge
sensor, ventilation pump and cooling fan are all operating correctly. If an abator is
attached to the sterilizer, it indicates that the abator pump is operating correctly as
well. The bottom line on this display indicates that the cooling fan is running at
100% of its nominal revolutions per minute (RPM).
6.1. VENT SENSOR FAILURE: Failure of the ventilation sensor during the self test
portion of the cycle will show the VENT SENSOR FAILURE message on the
screen. A vent sensor failure during the self test is often caused by a defective sensor.
In this instance, the sensor needs to be replaced.
6.2. PURGE SENSOR FAILURE: Failure of the purge sensor during the self test por-
tion of the cycle will show the PURGE SENSOR FAILURE message on the screen.
A purge sensor failure during the self test is often caused by a defective sensor. In
this instance, the sensor needs to be replaced.
6.3. PRESSURE SENSOR FAILURE: Failure of the pressure sensor during the self test
portion of the cycle will show the PRESSURE SENSOR FAILURE message on the
screen. A pressure sensor failure during the self test is often caused by a defective
sensor. In this instance, the sensor needs to be replaced.
6.4. VENT PUMP FAILURE: Failure of the ventilation pump during the self test potion
of the cycle will show the VENT PUMP FAILURE message on the screen.
Possible causes of VENT PUMP FAILURE during self test and remedies:
• The ventilation tubing has become disconnected inside the top cabinet. Reconnect
ventilation tubing.
• The ventilation vacuum pump has failed to generate the required vacuum. Replace
ventilation vacuum pump.
• The exhaust tubing from the ventilation pump is blocked. Remove obstruction.

OWNER’S MANUAL
Response: The cause of failure must be identified and corrected prior to starting the
sterilization cycle.
6.5. PURGE PUMP FAILURE: Failure of the purge pump during the self test portion of
the cycle will show the PURGE PUMP FAILURE message on the screen.
Possible causes of PURGE PUMP FAILURE during self test and remedies:
• Tubing inside the bottom cabinet has become disconnected or the sterilization bag is
not properly secured to the purge tube bobbin with the Velcro strap. Reconnect tub-
ing, recheck the integrity of the sterilization liner bag and retighten the Velcro strap.
• The purge pump failed to generate the required vacuum. Replace the purge pump.
• The purge tubing became disconnected inside the top cabinet. Reconnect purge tub-
ing.
• Exhaust tubing from purge pump is blocked. Remove obstruction.
Response: The cause of failure must be identified and corrected prior to starting the
sterilization cycle.
6.6. COOLING FAN FAILURE: Failure of the cooling fan located in the center rear of
the top cabinet during the self test portion of the cycle will show the COOLING FAN
FAILURE message on the screen.
Possible causes of COOLING FAN FAILURE during self test and remedies:
• If the fan is running, the cooling fan blade may be partially or completely obstructed.
This is indicated by a RPM value of less than 70% on the self test screen on the
previous page. Remove the obstruction, clean the filter and reinitiate the self test.
• If the fan is running but the indicated RPM value is 0%, the white feedback wire
from the fan may not be properly connected to the PC board. Check connection.
• If the fan is not running, check the connection of the red and black lead wires to the
PC board. If they are properly connected, check the voltage at the PC board
connector for the red and white wires. If you obtain a reading of 6 VDC, replace the
fan. If you obtain a reading of 0 VDC, the PC board may need to be replaced.
6.7. ABATOR FAILURE: Failure of the abator pump during the self test portion of
the cycle will show the ABATOR FAILURE message on the screen.
Possible causes of ABATOR FAILURE during self test and remedies:
• If the BNC Connector on the back of the AN 74 I is not attached to the sterilizer or to
the Abator, the Abator pump will not start. Check the connection. Listen to the
Abator to determine if the pump is starting when START is pressed.
• Check for an obstruction in the tubing between the sterilizer and abator. If there is a
complete obstruction it can cause an abator failure. Remove the obstruction and
repeat the self test.
• The abator pump may have failed. It will need to be replaced to continue.
38
OWNER’S MANUAL
Response: The cause of failure must be identified and corrected prior to starting the
sterilization cycle.
Error Messages During the Cycle (After the ampoule is activated)
6.8. CLOSE DOOR: The CLOSE DOOR message is accompanied by a constant audible
alarm and indicates that the sterilizer door is open when it should be closed. There is
a magnetic sensor in the upper left corner of the door frame that senses when the door
is closed. To turn off the alarm and message, close the door of the sterilizer.
6.9. VENT PUMP FAILURE (During the initial 12 (or extended 24) hours of the
sterilization cycle): Please note that sterilization takes place during the initial 12/24
hours of the cycle. If the vent pump fails during this time, the sterilization process
has been compromised.
If the ventilation pump fails during the sterilization portion of the cycle when a sub-
stantial amount of ethylene oxide remains within the sterilizer cabinet and the sterili-
zation liner bag, the paramount concern is the safety of the operator. If a ventilation
pump failure is sensed, the sterilizer will immediately start the purge pump. The
purge pump will then remove Ethylene Oxide from both the sterilization liner bag
and the cabinet by drawing air from the enclosed cabinet, into the sterilization liner
bag and then exhaust it to the outside thereby minimizing the risk of operator expo-
sure. If this happens, the sterilization time and concentration of ethylene oxide inside
the sterilization liner bag has been prematurely reduced and the items in the sterilizer
should not be considered sterile.
Response: The sterilization cycle is halted and a purge is initiated to minimize the
possibility of operator exposure to Ethylene Oxide. After the machine has completed
the two hour purge and is unloaded, the cause of the failure must be identified and
corrected prior to starting a new sterilization cycle.
CAUTION!: In this scenario, items in the sterilizer may not be sterile. Items must
be resterilized prior to use.
6.10. VENT PUMP FAILURE (During the purge cycle): The sterilization process takes
place in the first 12 hours of the sterilization cycle. If the vent pump fails during
hours 12 to 14 (or 24 to 26 during an extended cycle), the sterilization process has
not been compromised.
Instead of the vent pump and purge running alternating two minute cycles, the purge
pump will run continuously. The purge pump will remove Ethylene Oxide from both
the sterilization liner bag and the cabinet by drawing air from the enclosed cabinet,
into the sterilization liner bag and then exhaust it to the outside thereby minimizing
the risk of operator exposure.
39
OWNER’S MANUAL
If examination of the sterility indicators included with the load indicate adequate
time/concentration exposure to ethylene oxide, the items in the sterilizer may be con-
sidered sterile. The vent pump failure message will be displayed after the entire cy-
cle is complete, and the door has been opened to remove the load from the sterilizer.
Response: Sterilization cycle was completed normally. After the machine is
unloaded, the cause of the failure must be identified and corrected prior to starting a
new sterilization cycle.
6.11. PURGE PUMP FAILURE (During the purge cycle): The sterilization process
takes place in the first 12/24 hours of the sterilization cycle. If the purge pump fails
during the purge cycle, hours 12 to 14 (or hours 24 to 26 for extended cycles), the
sterilization process has not been compromised. However, if the purge pump fails,
there will be abnormally high concentrations of Ethylene Oxide inside the steriliza-
tion liner bag at the end of the normal 14 hour cycle. In response to this failure, the
sterilizer will: (1) immediately start the vent pump, which will now run continuously
until the end of the cycle; (2) add 24 hours to the total cycle time; and (3) display a
PURGE PUMP FAILURE message on the screen.
During this additional 24 hour aeration time, most of the remaining Ethylene Oxide
will pass through the wall of the sterilization liner bag. The sterilizer will count
down 24 hours and then instruct the operator to release the Velcro strap from the
neck of the sterilization liner bag and immediately close the door. The sterilizer will
then count down an additional 2 hours of aeration time to remove any residual Ethyl-
ene Oxide from the opened sterilization liner bag within the cabinet. If examination
of the sterility indicators included with the load indicate adequate time/concentration
exposure to ethylene oxide, the items in the sterilizer may be considered sterile.
Response: Sterilization cycle was completed normally, however, the sterilization
liner bag was not fully purged. The sterilizer will add 24 additional hours to the cy-
cle to allow residual Ethylene Oxide to pass through the sterilization liner bag. After
the machine is unloaded, the cause of the failure must be identified and corrected
prior to starting a new sterilization cycle.
ALARMS: If a critical component of the sterilizer fails during any part of the cycle, the
controller will notify the operator by means of a visual display and an audible alarm:
6.12 Ventilation Pump Alarm: If the cabinet ventilation pump fails to maintain an ade-
quate vacuum for 20 consecutive seconds while the ventilation pump is running, an
alarm will sound continuously and the display will read: VENT PUMP FAILURE.
The audible alarm may be silenced by pressing the EXIT button.
40
OWNER’S MANUAL
The ventilation sensor monitors the vacuum between the cabinet ventilation pump and
the interior of the cabinet. The pressure within the cabinet relative to the room is
negative (vacuum) which ensures the sterilizing gas which has diffused through the
walls of the sterilization liner bag is retained within the cabinet.
Before the ventilation pump is turned on at the beginning of the cycle, the controller
tests to make sure the ventilation sensor is reading zero vacuum. It then turns on the
ventilation pump and checks to see if there is adequate vacuum. If the vacuum is less
than 0.25 inches of water vacuum, the VENT PUMP FAILURE message will be dis-
played.
During the entire sterilization and ventilation cycle, the amount of vacuum created by
the ventilation pump is also continuously monitored while the vent pump is running.
If a VENT PUMP FAILURE message is displayed, the audible alarm may be silenced
by pressing the EXIT button.
As an automated safety precaution, if the cabinet ventilation pump fails at any time
during the 12 (or 24) hour sterilization cycle, the purge pump will automatically start
and run continuously for the remainder of the sterilization and ventilation cycle. The
sterilization liner bag will be vacuumed down until the check valves in the purge tube
open at 3.0” (7.6 cm) of water vacuum. At this point the check valves will open and
the cabinet will then be vented through the sterilization liner bag for the remainder of
the cycle.
6.13 Purge Pump Alarm: Similarly, the purge pump sensor monitors the vacuum within
the tubing that connects the purge pump to the sterilization liner bag. Before the purge
pump is turned on at the beginning of the cycle, the controller tests to make sure the
purge sensor is reading zero vacuum. The purge pump is then turned on and the sterili-
zation liner bag is vacuumed down. The controller checks to make sure the vacuum is
greater than 5.00 inches of water vacuum. Otherwise, the controller will display a
PURGE PUMP FAILURE message.
During the 2 hour ventilating bag cycle at the end of the 12 (or 24) hour sterilizing cy-
cle, the amount of vacuum created by the purge pump is also continuously monitored
while it is running. If the vacuum created by the purge pump is inadequate for 20 con-
secutive seconds, a PURGE PUMP FAILURE message is displayed.
If the purge pump fails during the 2 hour ventilation cycle, the controller will
automatically add 24 hours to the cycle time to allow the remaining Ethylene Oxide
contained within the sterilization liner bag to diffuse through the walls of the steriliza-
tion liner bag as opposed to being flushed with fresh air for 2 hours, as would occur

OWNER’S MANUAL
The first purge cycle takes place immediately prior to activation of the Anprolene am-
poule and commencement of the sterilization cycle. This cycle lasts for 1 minute, 30
seconds and is displayed as the INITIAL PURGE.
The second purge cycle is automatically initiated when the sterilization cycle has
reached the end of the 12 (or 24) hours. The purge cycle continues for two hours with
the display showing VENTILATING BAG - 02:00:00 REMAINING and counting
down to zero. At the end of the two hours, the sterilizer can be unloaded. The purge
pump runs for two minutes and then turns off for two minutes, alternating with the ven-
tilation pump during the ventilation cycle.
If the two hour VENTILATING BAG period has expired but: (1) the door to the steri-
lizer has not been opened; and (2) the EXIT button has not been pressed, the sterilizer
will continue to intermittently purge the sterilization liner bag. It will remain on this
schedule indefinitely until the door is opened and the EXIT button is pressed. In addi-
tion, the display will show a count-up timer indicating additional aeration time.
6.14 Abator Alarm: The alarm will beep 3 times on startup if the abator is down to 25 or
fewer remaining cycles. A constant alarm sounds when the abator is down to 0 cycles
remaining.
6.15 Power Outage: The program in the microchip is protected from power loss by a bat-
tery which is built into the clock chip mounted on the circuit board. The design enables
the program to continue in the event of a power loss by using the backup battery
power.
If a power outage occurs during the sterilization portion of the cycle, the program will
continue without interruption as if a power outage did not occur since the items inside
the sterilization liner bag will still be exposed to the Anprolene gas for the same
amount of time even if the power is off.
If a power outage occurs during the ventilation portion of the cycle, the program will
record how long the sterilization liner bag was ventilated prior to the power outage (for
example, 30 minutes) and it will resume the countdown for the remainder of the 2 hour
ventilation cycle. (in this example, an additional 1 hour, 30 minutes).

Maintenance
7.1. The cabinet ventilation pump and the sterilization liner bag purge pump have an ex-
pected life of 18,000 hours (this translates to approximately five cycles per week for five
years). During this time, the pumps are designed to pump at or above minimum required
volumes of exhaust air at up to 27 inches of water backpressure. The total number of hours
that the pumps have run is displayed on the Liquid Crystal Display at the beginning of each
sterilization cycle.
When the pumps have been in operation for more than 18,000 hours (approximately 1,300
sterilization cycles), it is recommended that the complete sterilizer unit be returned to the
factory for replacement and/or refurbishment of the pumps and associated tubing. Call
Andersen Products Customer Service for return authorization and pricing.
7.2. On a semi-annual basis, or every 1,800 hours of operation, the following mainte-
nance should be performed:
a. Check the quick connect fittings and the tubing that runs from inside the upper
right hand corner of the sterilizer cabinet to the purge tube.
b. All external tubing and tubing connections that are visible, and therefore
accessible to the operator, should be checked to make sure they are secure and that
there are no visible signs of degradation such as cracking or splitting.
c. Check the exhaust tubing connections at the back of the sterilizer and perform a
leak test as detailed in Appendix D, page 55 and following.
d. The filter media attached to the cooling fan in the rear of the top cabinet should be
removed, cleaned and reattached.
7.3 All exterior surfaces and the interior surfaces of the lower cabinet should be cleaned
using a cotton cloth and a mild soap and water solution. Do not use abrasive pads as this
may mar the finish of the stainless steel and plastic molded fittings.

OWNER’S MANUAL
APPENDIX A
Technical Features
A.1. Cabinet: The AN74i/ix cabinet is assembled from grain finish stainless steel with
molded ABS front and rear end plates. The door is assembled from a molded polystyrene
outer door and inner stainless steel liner. The door is provided with an exterior grain finish
stainless steel cover panel, door support arm and latching lock with removable key.
Protective rubber feet are attached to the lower cabinet panel.
A.2. Pumps: The lower cabinet is ventilated by means of two linear oscillating pumps
located in the enclosed top cabinet. The pumps remove the air from inside of the lower
cabinet and sterilization liner bag and exhaust the air to the outside. The 3/4” (1.9 cm) in-
side diameter braided PVC tubing may be up to 200 feet (60.96 meters) in length. During
sterilization and ventilation cycles, the pumps maintain a negative pressure (vacuum) in the
lower cabinet with respect to the room where the sterilizer is located. If an abator is in-
stalled it uses a third linear pump that is enclosed in the abator cabinet.
A.2.a. Ventilation Pump: The cabinet ventilation pump will run continuously from
the time the operator pushes the START button at the beginning of the cycle until the 12
or 24 hour sterilizing cycle is complete. After that, during the 2 hour purge cycle, it will
alternate with the purge pump, running for two minutes and then shutting down for two
minutes until the operator:
1.Opens the door to remove the sterilized items; and
2.Presses the EXIT button.
The cabinet ventilation pump is designed to exhaust the lower cabinet at a minimum rate
of 38 liters per minute. These specifications are for a cabinet equipped with a maximum
of 200 feet (60.96 m) of 3/4” (1.9 cm) inside diameter braided PVC tubing with one 90º
bulkhead fitting at the back of the cabinet and one 90º bulkhead fitting at the interior
wall above the sterilizer.
Additional Aeration: If the operator wishes to use the sterilization cabinet to further
aerate the sterilized items after the normal 14/26 hour sterilization and ventilation cycles
are completed, the operator may simply leave the sterilizer running when the UNLOAD
STERILIZER screen appears. A count-up timer will appear on the screen showing the
additional aeration time after the end of the normal 14/26 hour sterilization and aeration
cycle. When the operator wishes to stop the additional aeration, they simply need to fol-
low the steps outlined in A.2.a. above.
A.2.b. Purge Pump: The second exhaust pump, referred to as the purge pump, is
connected to the purge tube assembly and sterilization liner bag by a tube connected to
the front right corner of the lower cabinet. Purging is the intermittent flushing of the
sterilization liner bag with fresh air and takes place at the beginning and end of the cycle.

Statement of Hazards:
DANGER!
Extremely flammable liquid and gas under pressure. May form
explosive mixtures with air. Highly reactive. May be harmful if in-
haled and may cause delayed lung injury, respiratory system and
nervous system damage. Inhalation may cause dizziness or drowsi-
ness. Liquid contact may cause frostbite. May cause allergic skin
reaction. Harmful if swallowed. May cause adverse blood effects,
liver and kidney damage based on animal data. Cancer and repro-
ductive hazard.
HAZARD RATINGS: (0 = minimum; 4 = maximum)
HMIS RATING: Health = 3
Flammability = 4
Reactivity = 3
Personal Protection Code = x (Consult your
supervisor or standard operating procedures
for special handling directions.)
NFPA RATING: Health = 3
Flammability = 4
Reactivity = 3
Exposure Limits:
TWA (8 hr) STEL (15-min)
OSHA 1 ppm 5 ppm
ACGIH 1 ppm n/a
PRIMARY ROUTES OF EXPOSURE: Inhalation; eye contact, skin
contact/absorption
SIGNS AND SYMPTOMS OF OVEREXPOSURE: Effects include
skin, eye and respiratory tract irritation or burns. Central nervous
system effects initially cause headache, dizziness and nausea and in
extreme cases, unconsciousness and death. Peripheral nerve dam-
age may result in muscular weakness, giddiness, irrational behavior
and loss of sensation in the extremities. Dulling of the sense of smell
may occur.
ACUTE HEALTH EFFECTS:
INHALATION: Inhaling concentrated vapor may cause serious
health effects. Inhalation may progressively cause mucous mem-
brane and respiratory irritation, headache, vomiting, cyanosis, drowsi-
ness, weakness, in coordination, CNS depression, lachrymation,
nasal discharge and salivation, gasping, and labored breathing.
Delayed effects may include nausea, diarrhea, edema of the lungs,
paralysis and convulsions. NOTE: Ethylene oxide has a high odor
threshold (>250 ppm) and the sense of smell does not provide ade-
quate protection against its toxic effects.
EYE CONTACT: Liquid ethylene oxide is severely irritating and
corrosive to the eyes and contact can cause swelling of the conjunc-
tiva and irreversible corneal injury. Contact with liquid ethylene oxide
can cause frostbite. Vapors may cause eye irritation, tearing, red-
ness and swelling of the conjunctiva.
70
OWNER’S MANUAL
SKIN CONTACT: Prolonged contact with liquid ethylene oxide can
cause a local erythema, edema, and formation of blisters. Response
is more severe on damp skin. There may be a latency period of
several hours prior to the onset of symptoms. Ethylene oxide may
be absorbed by the skin, and sustained contact may produce ad-
verse effects such as headache, dizziness, nausea, and vomiting.
Ethylene Oxide is a skin sensitizer and some individuals may suffer
an allergic skin reaction. Skin contact may also cause allergic con-
tact dermatitis in some exposed individuals. Liquid Ethylene oxide
evaporates rapidly and may chill the skin causing frostbite.
INGESTION: This relatively unlikely route of exposure is expected to
cause severe irritation and burns of the mouth and throat, abdominal
pain, nausea, vomiting, collapse and coma. Aspiration may occur
during swallowing or vomiting, resulting in lung damage.
CHRONIC HEALTH EFFECTS:
SKIN CONTACT: Long term effects are unknown but are expected
to be similar to acute effects of skin exposure.
EYE CONTACT: Some cases of cataract formation have been re-
ported.
INHALATION: Respiratory irritation which can result in permanent,
lung injury, chromosomal aberrations and peripheral neurotoxic
effects with a numbing of the sense of smell. Cognitive and CNS
impairment may result from long term exposures.
INGESTION: May cause anemia, gastrointestinal irritation, effects
on liver, kidneys, and adrenal glands.
CARCINOGENICITY:
OSHA classifies ethylene oxide as a cancer/ reproductive hazard
and considers that, at excessive levels, ethylene oxide may present
reproductive, mutagenic, genotoxic, neurologic and skin sensitization
hazards.
ACGIH classifies ethylene oxide as “A2”- suspected human carcino-
gen.
NTP classifies ethylene oxide as a known human carcinogen.
IARC classifies ethylene oxide in Group 1 (carcinogenic to humans).
NIOSH classifies ethylene oxide as a potential human carcinogen.
EYE CONTACT: Immediately flush eyes, including the entire sur-
face of the eyes and under the eyelids, gently but thoroughly with
plenty of running water for at least 15 minutes. Obtain medical atten-
tion immediately. NOTE: Never wear contact lenses when work-
ing with ethylene oxide.
SKIN CONTACT: Immediately flush skin thoroughly with water for at
least 15 minutes while removing contaminated clothing and shoes.
Obtain medical attention immediately. Wash clothing before reuse
and discard contaminated leather articles such as shoes and belts.
INHALATION: Remove exposed person to fresh air. If breathing
has stopped, give artificial respiration then have qualified personnel
administer oxygen, if needed. Get immediate medical attention.
INGESTION: If patient is conscious give plenty of water ( minimum
of two glasses) but DO NOT INDUCE VOMITING. This material is
corrosive. Keep head lower than hips to avoid aspiration, should
vomiting occur. Get medical attention immediately.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Preexisting skin, eye and respiratory disorders; lung, blood, nervous
system and peripheral nerve disorders.
NOTE TO PHYSICIANS: Respiratory symptoms include nausea,
vomiting and irritation of the nose and throat. Pulmonary edema
may occur. Respiratory effects may be delayed. Consider oxygen
administration. If a chemical burn is present decontaminate skin
and treat as any thermal burn. No specific antidote is known, how-
ever consider gastric lavage and administration of a charcoal slurry.

NEFA HAZARD RATING:
Health: 3 Flammability: 4 Reactivity: 3
AUTOIGNITION TEMPERATURE:
804 F (429C); burns in the absence of air
EXTINGUISHING MEDIA: Carbon dioxide, dry chemical or water
spray for small fires. Water spray, polymer or alcohol resistant
foams for large fires. Dilution of liquid ethylene oxide with 23 vol-
umes of water should render it non-flammable. Dilution with 100
parts water to one part of ethylene oxide vapor may be required to
control build up of flammable vapors in closed systems. Water spray
can be used to reduce intensity of flames to cool fire-exposed con-
tainers and to dilute spills to render non-flammable.
HAZARDOUS DECOMPOSITION PRODUCTS: Carbon monoxide
and carbon dioxide.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Ethylene oxide is
dangerously explosive under fire condition; it is flammable over an
extremely large range of concentrations in air and burns in the ab-
sence of oxygen. Liquid ethylene oxide is lighter than water (floats)
and vapors are heavier than air and may travel along ground long
distances to sources of ignition and then flash back. Containers
should not be subject to temperatures hotter than 127F (52 C).
Vapors are extremely flammable and are readily ignited by static
charge, sparks and flames at concentrations above 3%.
PRECAUTIONS: Treat any ethylene oxide leak as an emergency.
Evacuate all personnel from the area except those directly engaged
in stopping the leak or in cleaning up. If an Anprolene ampoule is
inadvertently dropped and activated before it is sealed inside of the
sterilization liner bag, it will still take time for the ethylene oxide
Section 4
First Aid Measures
Section 5
Fire Fighting Measures
Section 6
Accidental Release Measures
71
OWNER’S MANUAL
to diffuse out of the gas release bag and into the room. At one full
minute after activation there is less than 1 ppm measured at a dis-
tance of 18 inches from the gas release bag. In the case of a pre-
mature activation the operator should immediately:
• Place the Anprolene ampoule inside the sterilizer
• Close the sterilizer door
• Turn the power on; and
• Press the button to the right of PURGE.
This will cause the purge and ventilation pumps to turn on and
evacuate the ethylene oxide from the sterilizer and exhaust it from
the workspace. Allow a full 14 hour cycle before you open the door
and remove the used Anprolene ampoule and dispose of it.
HANDLING AND STORAGE PRECAUTIONS: Have established
handling and emergency response procedures in place prior to use.
Make sure that the sterilizer is properly grounded. Protect contain-
ers from physical damage and regularly inspect them for cracks or
leaks.
ENGINEERING CONTROLS: Ethylene oxide, a major fire hazard,
can burn in the absence of oxygen. All electrical devices used in
areas processing or handling ethylene oxide must be engineered
and designed to the applicable local electrical/fire codes. Safe-
guards can include designing electrical devices as explosion proof
and/or intrinsically safe. ATTENTION: Ethylene oxide vapors are
colorless and odorless above OSHA’S permissible exposure level.
An air monitoring system and/or AirScan® badges are recom-
mended to determine airborne exposure levels.
STORAGE SEGREGATION: Store ethylene oxide in a cool, dry,
well-ventilated area away from incompatible chemicals and sources
of ignition. Store Anprolene® refill kits upright; do not drop and
move in a carefully supervised manner. DO NOT STORE IN
DIRECT SUNLIGHT.
SHIPPING AND STORAGE CONTAINERS: (See 49 CFR 173.4)
All Anprolene® refill kits containing ethylene oxide are packaged and
shipped in accordance with the small quantities exemption under 49
CFR 173.4(c) and DOT approval CA 9803005 issued April 9, 1998.

OWNER’S MANUAL
Various mammalian species exposed to lethal concentrations of
ethylene oxide had symptoms of mucous membrane irritation, central
nervous system depression, lacrimation, nasal discharge, salivation,
nausea, vomiting, diarrhea, respiratory irritation, incoordination, and
convulsions.
TOXICOLOGICAL-CHRONIC INHALATION: Symptoms of chronic
exposure are similar to those observed in acute studies, including
lung, kidney and liver damage and testicular tubule degeneration in
some species. Studies demonstrated neuromuscular effects as the
most sensitive indicator of ethylene oxide over exposure.
TOXICOLOGICAL-ACUTE DERMAL: No dermal LD50 information
is available on this product. It is expected to be corrosive to rabbit
skin.
TOXICOLOGICAL – CHRONIC DERMAL: No chronic dermal
toxicity data are available on this product.
TOXICOLOGICAL- EYE: No eye irritation animal data are available
on this product. However, it is expected to extremely irritating to
rabbit eyes.
TOXICOLOGICAL-ACUTE INGESTION: The acute oral LD50 for
This product is; 72 mg/kg, rat
TOXICOLOGICAL-CHRONIC INGESTION: The effects of chronic
ingestion of this product are unknown
CARCINOGENICITY: A recent assessment of available
epidemiology studies related to ethylene oxide concluded that the
evidence indicates that ethylene oxide does not cause heart disease,
an excess of cancers overall, or brain, stomach or pancreatic cancers
which were seen in some animal and isolated human studies. The
findings with respect to leukemia and non-Hodgkins lymphoma are
less definitive. While the majority of the evidence does not indicate
that ethylene oxide causes these cancers, there are some suggestive
trends. Longer follow-up of ethylene oxide workers is needed to
better clarify these relationships. Two inhalation studies with rats
demonstrated carcinogenic responses consisting of increased inci-
dences of mono-nuclear cell leukemia, peritoneal mesotheliomas ,
and primary brain tumors. In 2-year inhalation studies with mice
there was evidence of carcinogenic activity as indicated by dose-
related incidences of benign or malignant neoplasms of the uterus,
mammary gland, and hematopoietic system (lymphoma).
MUTAGENICITY: While ethylene oxide has demonstrated, in epide-
miological studies with exposed workers, an increased incidence of
chromosomal aberrations and sister chromatid exchanges, the rele-
vance of such effects to human health hazard evaluation is currently
uncertain. In rodent studies, dose related exposure to ethylene oxide
induces increases in numbers of adducts in DNA and hemoglobin.
Laboratory studies with mice have shown that acute exposure to
ethylene oxide at 300 ppm and above caused testicular injury as
evidenced by concentration-related increased embryonic deaths
following mating of exposed males to non-exposed females
(Dominant-Lethal Test).
NEUROTOXICITY: Effects are similar to those of acute (short term)
exposure, namely headaches, nausea, diarrhea, lethargy, and
irrational behovior. Muscle weakness, loss of sensation in the
extremities and a reduction in the sense of smell and/or taste may
also result. Studies on workers Indicate that CNS and cognitive im-
pairment may result from chronic exposures to ethylene oxide.
REPRODUCTIVE EFFECTS: Some limited epidemiological data
suggests that women exposed to ethylene oxide have a greater
incidence of miscarriages. A one-generation reproduction study in
rats showed decreased number of pups at 100 ppm, but not at 33
ppm. In a two-generation reproduction study involving exposure of
rats to ethylene oxide vapor for 5 hrs/day, 5 days/week, there was
parental toxicity at 33 ppm and 100 ppm. The no-observable effect
concentration for adult toxicity, offspring effect and reproductive
effect was 10 ppm.
TERATOLOGY: Inhalation development toxicity studies with rats
exposed to ethylene oxide vapor at concentrations of 50 ppm, 125
ppm and 225 ppm showed that maternal toxicity occurred at 125 and
225 ppm. Fetotoxicity, evidenced by reduced fetal body weight,
occurred at all concentrations. At 225 ppm and to a lesser extent at
125 ppm an increased incidence of skeletal variants was found.
There was no evidence of embryotoxicity or malformations.
TARGET ORGANS: Overexposure to this product may affect the
skin, eyes, respiratory system, liver, kidneys, brain, blood, reproduc-
tive system, and central nervous system.
ECOTOXICOLOGICAL DATA: Ethylene oxide hydrolyzes to ethyl-
ene glycol. Biodegradation of ethylene oxide occurs at a moderate
rate after acclimation (3-5% degradation after 5 days; 52% after 20
days). Biodegradation is expected in a wastewater treatment plant.
Ethylene oxide has an estimated half-life in the atmosphere of 211
days. A high adsorptivity in soil is expected.
WASTE MANAGEMENT/DISPOSAL: Dispose used Anprolene
ampoules, sterilization liner bags, indicators and accessories as you
would ordinary trash.
However, unused Anprolene ampoules containing ethylene oxide
are a RCRA hazardous waste with waste code U115 (Commercial
chemical product - listed for toxicity and ignitability). Unused
Anprolene ampoules containing ethylene oxide may be incinerated in
an approved hazardous waste incinerator or can be biologically
treated in an approved facility. Unused Anprolene ampoules con-
taining ethylene oxide are banned from land disposal.
Dispose of waste materials in accordance with all applicable Federal,
State and local laws and regulations.

OWNER’S MANUAL
ANDERSEN One-Year Limited Warranty
Andersen Products, Inc. (“Andersen”) warrants that this Anprolene© Sterilizer (“Product”) is free from defects in mate-
rial and workmanship that result in Product failure during normal usage, according to the following terms and condi-
tions:
1. The limited warranty for the Product extends for ONE (1) year beginning on the date of the purchase of the Product.

ferable to any subsequent purchaser/end-user.

pan, Mexico, Central and South America and the Caribbean.
4. During the limited warranty period, Andersen will repair, or replace, at Andersen's option, any defective parts, or any
parts that will not properly operate for their intended use with new or factory rebuilt replacement items if such repair or
replacement is needed because of product malfunction or failure during normal usage. No charge will be made to the
Consumer for any such parts. Andersen will also pay for the labor charges incurred by Andersen in repairing or re-
placing the defective parts. The limited warranty does not cover defects in appearance that are cosmetic or decorative.
Andersen's limit of liability under the limited warranty shall be the actual cash value of the Product at the time the Con-
sumer returns the Product for repair, determined by the price paid by the Consumer for the Product less a reasonable
