2. SAFETY INSTRUCTIONS

The autoclave has unique characteristics. Please read and understand
the operation instructions before first operation of the autoclave. This
manual includes instructions and guidance provided by the
manufacturer: how to operate the autoclave, the door safety
mechanism, and the dangers involved in circumventing safety means,
how to ensure that the door is closed, and how to select a correct
sterilization program.

Make sure that you know where the main power switch is located.

Autoclave maintenance is crucial for the correct and efficient function of
the device.

Never use the autoclave to sterilize corrosive products, such as: acids,
bases and phenols, volatile compounds or solutions such as ethanol,
methanol, chloroform or radioactive substances. Below are the
operating instructions – safety instructions:

1. All autoclave users must receive training in proper usage from an
experienced employee. Every new employee must undergo a
training period under an experienced employee.

2. When sterilizing plastic materials, refer to the item manufacture
information and make sure that the item can withstand the
sterilization temperature. Plastic that melts in the chamber is liable
to cause a great deal of damage.

3. On closing the device door, make sure it is properly locked before
activating. Verify that the DOOR OPEN symbol is replaced by
“System Ready”.

4. When withdrawing trays, use the enclosed tray handle or wear
heat resistant gloves.

5. The door is electronically locked and will not open unless the
pressure in the chamber equals the atmospheric pressure
(chamber pressure is displayed on the screen).

6. The door also remains locked if there is a cycle failure or the unit
has no power.

7. Open the door slowly to allow steam to escape.

8. Once a month, ensure that the safety valve is operating, and once
every 5 years a certified inspector must perform a chamber
pressure safety test.

9. Make sure there are no leaks, breaks, blockages, whistles or
strange noises.

10. Perform maintenance operations as instructed. The owner of the
autoclave is responsible to perform the maintenance operations.

11. Notify the person in charge immediately of any deviation from the
proper function of the device.

12. Protective equipment and clothes and other safety instructions
should be implemented in accordance with local and national
regulations and/or rules!

3. GENERAL INFORMATION

3.1. Introduction

The EZPlus tabletop autoclave is designed for sterilization of
wrapped and unwrapped instruments, and related items found in
dental, medical, and veterinary clinics, first aid rooms, hospitals,
laboratories etc.

This autoclave is an electrically – heated sterilizer using steam

as the sterilizing agent. This unit uses steam flush pressure

pulse technology for removing air from the chamber. A

computerized control unit ensures a fully automatic sterilization

cycle, control and monitoring of physical parameters and a clear

documentation of the sterilization cycle.

The autoclave offers a choice of four automatic programs and

two custom programs designed to match the material to be

sterilized. In addition there is a dedicated cleaning program. The

autoclave is equipped with an Air Assisted Drying system. This

includes an air pump that during the drying stage draws air

through a HEPA filter (0.2µm) and circulates that air through the

heated chamber to remove moisture and facilitate the drying

operation. Drying is performed with the door closed.

On all models, a water pump is installed between the water

reservoir and the chamber. This pump guarantees fast and

accurate filling of the chamber every time. Entry of water may be

accompanied by a noise for approximately 30 seconds. This is

normal noise generated by the regular operation of the pump.

The EZPlus series features a digital absolute pressure display
for monitoring and control purposes. The pressure display
indicates if there is pressure in the chamber. The device is
capable of displaying the pressure in psia, psig, or in kPa
according to the operator’s requirements. When the pressure is
displayed in psig, the atmospheric pressure is shown (at sea
level) as 0 psig. If the pressure is defined in psia or kPa the
absolute zero is displayed as “0” and the atmospheric pressure
is shown (at sea level) as 14.7 psia or 100 kPa respectively.

Note: This unit comes from the factory with the pressure
parameter set to display in psig.

The EZPlus can display temperature in ºF or ºC.

Note: The unit comes from the factory set to display
temperature in ºF.

Page 9

The control system is designed to meet the most current
sterilization standards to ensure efficacy, safety of personnel
and reliable operation. See sec. 3.9

A printer is an optional addition to the autoclave. The printer
prints the preset and actual parameters of the cycle
(temperature, time and pressure).

The EZPlus features built in memory to record up to 100
sterilization cycles. These can be reprinted on the optional
printer or exported to a USB device to be transferred to a PC.

The EZPlus has a built in Network Port for use with Tuttnauer’s
R.PC.R software when connected to your local network.

The R.PC.R software has been developed especially for the
Tuttnauer autoclaves.

This application will allow you to:

 Monitor up to 8 autoclaves
 Monitor the real time activity of any autoclave connected via

the network port.

 Manage the history files of the cycles run on your autoclave.

The history files can be downloaded either directly through a
physical connection to the network port or transferred
manually using a USB device.

 Store all the history of the processes that have been run on

your autoclave

 Track the parameter setting that have been used in each of

the cycles and stages run.

 Choose the style of the report to view; either graph, table, or a

print out

 All reports can be saved as a PDF.
 The graph style report offers the user an option to customize

the inputs and outputs used in the presentation.

For more information on the R.PC.R refer to the R.PC.R user
guide.

This manual is intended for the user and gives the user a
general understanding of the instrument and the best ways to
operate and take care of it in order to obtain effective results.

Before operating this autoclave read carefully this operation
manual. After reading this manual, operating the autoclave will
be easy. However since this instrument is built with high
technology sensitive components, no attempt should be made
by the user or any other unauthorized person to repair or
recalibrate it.

transferring to a PC for storage or printing.

 The network port (located on the rear of the unit) can be

used to connect to a local network and download
information to Tuttnauer’s R.PC.R software.

The RPCR software has been developed especially for the
Tuttnauer autoclaves and is an excellent report generating tool.

This software will allow you to:

 Monitor up to 8 autoclaves
 Monitor the real time activity of any autoclave connected via

the network port.

Page 24

 Manage the history files of the cycles run on your autoclave.

The history files can be downloaded either directly through a
physical connection to the network port or transferred
manually using a USB device.

 Store all the history of the processes that have been run on

your autoclave

 Track the parameter settings that have been used in each of

the cycles and stages run.

 Choose the style of the report to view; either graph, table, or a

print out

 All reports can be saved as a PDF.
 The graph style report offers the user an option to customize

the inputs and outputs used in the presentation.

For more information on the R.PC.R refer to the R.PC.R user
guide.

 The printer is an optional device. It prints the detailed history of

each cycle performed by the autoclave. The printing is on
thermal paper with 24 characters per line and records the
sterilization cycle information for subsequent consideration.

4.2. Displayed Error Messages / Symbols

An error message is displayed when a failure occurs. The
failures are divided into two categories.

1. Failures that occur before completing the sterilization stage,

6. STERILIZATION PROGRAMS

The control system incorporates a safety feature that prevents
changing programs if the door is closed.

This protection is intended to prevent running an inappropriate program
if the autoclave is loaded, but the cycle is not immediately started.

If the operator for example inserts the load into the chamber, closes the
door and leaves the room and another operator/user tries to change
the program, the operator/user will not be able to do this unless the
door is opened and the type of load inside the chamber can be seen.

The autoclave offers four preset FDA cleared sterilization programs, a
dedicated cleaning program (for cleaning the chamber using Chamber
Brite), a calibration program (for use by a technician) and two custom
programs. The custom programs are not FDA cleared and it is the

user’s responsibility to validate these programs.

Spore testing is your only assurance of complete sterilization.

Using the UP OR DOWN keys enables the user to select the various

programs as seen in the following list:

 Do not rub the papers with hard substance.
 Keep the papers away from organic solvent.

CAUTIONS!

Never disassemble the printer. Failure to follow

this instruction may cause overheating or burning
of the printer or AC adapter or an electric shock,
which may lead to fire or personal injury.

Use caution when cleaning the printer or

autoclave. Splashing water, cleaning solution or
other liquids into the printer can cause fire or
electrical shock.

Page 76

Never touch the thermal head immediately after

printing as it becomes very hot. Make sure that the
thermal head is cool before setting papers or
cleaning the thermal head.

Power OFF the autoclave in any of the following

cases:

 The printer does not recover from an error.
 Smoke, strange noise or smells erupt from the

printer.

 A piece of metal or any liquid touches the internal

parts or slot of the printer.

Page 77

9. INSTALLATION INSTRUCTION

9.1. Lifting and carrying

CAUTION!
Any time the autoclave is to be moved, make sure that the

electric cord is disconnected from the power source, and
there is no pressure in the chamber.

1. Disconnect the power supply cord from the rear of the
autoclave.

2. Drain any water that may be in the reservoir or chamber.

Note: Lifting straps have been provided with this unit. Lifting

straps are for one time use and should be removed and
discarded after initial set up.

To avoid injuries, lifting and carrying should be done by two
people.

Do not drop the device!

9.2. Placing

CAUTION!
The sterilizer must be placed on a rigid and leveled surface.
The counter top or stand must be able to withstand the load
of the device and loaded material. See sec. 3.3 for unit
specifications.

Note: This unit requires a minimum counter depth of 22”

Note: Make sure while placing the autoclave, to leave space

around the machine for ventilation and to give the technician
access to service the machine. It is recommended that a minimum
2” (50mm) space be provided. Insufficient space for ventilation
may result in an increase of the autoclave’s temperature which
may damage the unit.

9.3. Electrical

The electrical connection should comply with the devices power
requirement. It must also comply with local installation and safety
rules and regulations. The voltage supplied to the device must
comply with the device label ± 5%.
Note: It is recommended that the device be on a dedicated
electrical circuit.

Page 78

Note: The autoclave must be connected to a properly grounded
outlet.

In order to avoid any personal injury due to electrical shock, it is
mandatory to have installed an earth leakage relay (GFCI outlet or
circuit breaker) in the electrical circuit to which the autoclave is
connected. This relay disconnects all electrical power in case of
accidental contact with any electrically energized parts of the
autoclave,

9.4. Setup

Your new Tuttnauer Autoclave was programmed and tested at the
factory and requires a minimum of setup.

1. Make sure the counter is level and sturdy see sec. 9.2 above.

2. Make sure all the feet are on the autoclave and none of them has
been lost.

Use only steam distilled water having the characteristics
described in sec. 3.8

1. Open the door (1). The autoclave needs to be on for the door to
open.

2. Pour steam distilled water, gently, into the front funnel (2) until it
reaches the top of the blue area (3) on the level gauge. If water is
filled above the blue area into the red area (4) then use the drain
hose to drain off the over fill (see sec. 12.2 ). It is preferable to
use a carafe or small pitcher when filling.

Note:

This reservoir is designed with an over flow and filling the
reservoir above the safe level as indicated on the Front Fill Funnel
will cause excess water to spill out below the machine onto the
counter.

CAUTION!
Under no circumstance should water be filled higher than the
blue area (3) on the level gauge.

3. If the reservoir is empty, it can be filled quickly by adding water
directly through the opening at the top of the reservoir, as follows:

CAUTION!
Before filling the reservoir, verify that the autoclave is not
running a cycle.
Note:

This reservoir is designed with an over flow and filling the
reservoir above the safe level as indicated on the Front Fill Funnel
will cause excess water to spill out below the machine onto the
counter.

4. Remove the water reservoir cover (6).

5. Pour steam distilled water into the reservoir through the opening
on top of the autoclave until it reaches the base of the safety
valve holder (7) or reaches the top of the blue area of the level
gauge.

CAUTION!
Under no circumstance should water be filled above the safety

valve holder.

In case more water is accidentally filled above the blue area,
or safety valve decrease the water level by draining the
reservoir before starting a cycle (see sec. 12.2 ).

CAUTION!
USE STEAM DISTILLED WATER ONLY having the

characteristics as per table in sec. 3.8. The impurities in water

from a well, spring or municipal water supply will create the need
for more frequent cleaning and maintenance

This type of water can damage your instruments, your unit and void

your warranty.

10. PREPARATION BEFORE STERILIZATION

The purpose of packaging and wrapping of items for sterilization is to
provide an effective barrier against contamination once the items have
been sterilized and removed from the sterilizer.

Packaging and wrapping materials should permit the removal of air
from the pack during heating, penetration of the steam vapor into the
pack during sterilization and removal of the steam vapor during drying.

The basic principle determining the size, mass and contents of
instrument pouches, cassettes and hollowware packs is that the
contents are sterile and dry immediately on completion of the drying
cycle and removal from the sterilizer.

Instruments to be sterilized must be free from any residual matter, such
as debris, blood or organic tissue. Instruments must also be dry and
free from mineral deposits. Such substances may cause damage to the
instruments themselves or the sterilizer.

Correct loading of the autoclave is essential for successful sterilization.
Efficient air removal from the chamber and load will permit total steam
penetration and saturation. Additionally, correct loading will promote
efficient drying and reduce damage to packs and their contents and
maximize the effectiveness of the sterilizer.

Notes: In order to protect sensors at the back bottom of the chamber, the

rack of the EZ11Plus is designed with stops for the bottom tray.
It is normal for the bottom tray to be closer to the door than the other
trays.

Pushing the bottom tray all the way back will cause it to interfere with
the chamber sensors.

1. Check the instructions of the instrument manufacturer as to the
proper procedure for cleaning and sterilizing each item. The
instrument manufacturer’s instructions always supersede any
other instructions.

2. Clean instruments immediately after use to remove any residue. It
is recommended that all instruments be ultrasonically cleaned
using TuttnauerTMClean & Simple enzymatic cleaning tablets or
other suitable solution.

3. After cleaning, rinse instruments under tap water for 30 seconds
and pat dry to remove residual minerals. If your tap water has a
high mineral content then rinse a second time in a bath of distilled
water to remove minerals and pat dry.

4. Launder textile wraps prior to sterilization, thoroughly rinse wraps
laundered in chlorine bleach. Chlorine bleach can harm your
stainless steel instruments and the sterilizer.

5. Follow the instrument manufacturer’s instructions on the use of
products for cleaning and lubricating instruments that have been
ultrasonically cleaned.

Page 82

6. Be sure that instruments of dissimilar metal (stainless steel,
carbon steel, etc.) are separated. Carbon steel instruments should
be bagged or placed on autoclavable towels and not directly on
stainless steel trays (mixing will result in damage to the
instruments or trays from the electrolysis of these materials).

7. Load items within the boundaries of the tray so that they do not
touch the chamber walls, or fall off when the tray is moved. Items
should not be allowed to touch the walls of the Chamber as the
hot metal can damage the item.

8. Don’t overload the sterilizer trays. Overloading will inhibit
sterilization and produce poor drying results.

9. Items must be sterilized in an open position. Surfaces that are
hidden because the item is in a closed position will not be exposed
to the steam and will not be sterilized.

10. Make sure that all instruments remain apart during the sterilization
cycle. Surfaces that are hidden because items are covering other
items will not be exposed to steam and will not be sterilized.

11. Disassemble or sufficiently loosen multiple-part instruments prior
to packaging to permit steam to come into contact with all parts of
the instrument.

12. Verify that packaging methods are in accordance with the good
practice approach and the packaging materials used are in
agreement with applicable standards.

13. Tilt on edge items prone to entrap air and moisture, e.g.
hollowware, so that only minimal resistance to removal of air, the
passage of steam and condensate will be met.

14. Allow a distance of approximately 1” (2.5 cm) between trays to
permit steam circulation.

15. Wrapped instruments should be placed in material which will allow
steam penetration and promote drying, such as autoclave bag,
autoclave paper, or muslin towels.

16. When using a paper / plastic bag, the plastic side should always
be up.

17. Do not stack pouches. It is recommended that a pouch rack such
as the TuttnauerTMPouch Rack be used to ensure proper steam
penetration and adequate drying. Surfaces that are hidden
because the items are being stacked will not be exposed to the
steam and will not be sterilized.

Page 83

18. Empty canisters should be placed upside-down, in order to
prevent accumulation of water (see the figure below).

19. When sterilizing glassware use only heat-proof glass. Glassware
needs to be placed on the tray with the open end down.

20. Tubing should be rinsed after cleaning. When placed in the tray
making sure that both ends of the tubing are open and there are
no sharp bends or twists.

21. Cassettes or packs should be placed on the tray rack in place of
the trays. They should not be touching each other or the Chamber
walls. There should be about ½” between cassettes or packs for
proper steam circulation. Cassettes in an EZ9Plus should be
sterilized in a horizontal position (see the figure below).

Wrong

Right

Page 84

22. Cassettes in an EZ11Plus should be sterilized in a vertical position
(see the figure below).

To adjust the rack for vertical sterilization of cassettes
remove the trays and gently squeeze the sides of the
rack inward and at the same time rotate the rack into a
vertical position.

23. Small packs can be placed directly on the tray in an upright
position. They should not be touching each other or the Chamber
walls. There should be about ½” to 1” between packs for proper
steam circulation.

Page 85

24. Place a sterilization indicator on each tray and/or inside each
wrapped cassette.

25. At least once a week use a biological spore test (Bacillus
Stearothermophilus) in any load to insure proper sterilization (be
aware testing standards may vary). Always follow the spore test
manufacturer’s instruction.

26. If spotting is detected on the instruments it is necessary to
determine if the spot is dirt or oxidation. The first step would be to
use an ordinary eraser to remove the spot. If there is no pitting
under the spot then the spot is only dirt. Dirt spots on an
instrument may be an indication that the autoclave needs to be
cleaned or that the instruments were not adequately cleaned prior
to sterilization. If removal of the spot reveals pitting then the spot
is most likely oxidation. Oxidation spots on an instrument are not
uncommon on inexpensive instruments. It may also be an
indication that the instruments were rinsed in tap water with a high
mineral content. These minerals when exposed to high
temperature and steam will accelerate the oxidation of the metal.
One suggestion would be to final rinse the instruments in a
distilled water bath and pat dry to absorb residual water and
minerals.

27. If the instruments exhibit a discoloration this can be due to the
mixing of carbon steel and stainless steel. When these two metals
come into contact with each other electrolysis occurs that breaks
down the metal. The best solution is to separately wrap the carbon
steel instrument to insulate it from other instruments on the tray
and from the tray itself.

28. This unit is not approved for sterilizing liquids of any type.

11. OPERATING INSTRUCTIONS

11.1. Turning on the autoclave

1. Plug the power cord into the back of the autoclave and into the
wall outlet.

2. Turn on the rocker switch mounted on the side of the front panel.

11.2. Pre-Heating (EZ11Plus only)

This feature keeps the chamber hot between cycles to provide optimal
drying results when running the “Wrapped Instrument, Pouches” or
“Handpiece” or “Custom A” cycles Pre-heating is active during stand-by
unless the autoclave is in screen saver mode. The screen saver mode
is set to activate after 90 minutes of inactivity, to modify this time see
sec. 7.2.3.

Note: Pre-heating activates automatically every time you turn the
autoclave on and the “Wrapped Instrument, Pouches”, “Handpiece” or
“Custom A” cycles are selected.. Use caution since pre-heating will
make the bottom of the chamber hot.

If you press start during pre-heating, the following screen appears:

1

Page 87

In this case, there is no need to press start again: when the required
pre-heat temperature is reached, the process will start automatically.

Pressing start again will result in the following screen:

11.3. Opening the door

This machine is equipped with an electronic door lock. The door will
not open when the sterilizer is running a cycle or the power is off or the
display screen does not say “System Ready” or if the “Water in the

Chamber” icon is displayed.

When “System Ready” is displayed on the screen, open the door by
following these steps:

1. Place your thumb on the plastic door cover (1) and the other fingers

in the handle (3).

2. Pull the handle (2) until the latch of the door is released.

3. Open the door.

Page 88

4. With the door open you can now fill the reservoir as per
instructions in section 9.5

Note: The first time you start the unit it is important to set the
date and time (see sec. 7.1.6)

11.4. Adding additional drying time

If the default drying time is not adequate for the load to be sterilized,
additional drying time can be added. See sec. 7.1.1 for detailed
instructions on adding extra drying time.

Tuttnauer strongly suggests that each user/operator learn how to
arrange the load and apply additional drying time. This will ensure that
your sterilizer provides efficient drying of the pouched and/or wrapped
instruments used in your office
Tuttnauer affords you the ability to adjust drying times to accommodate
various instrument loads. Since no two instrument loads are the same it
is important to match the drying time with the load. In addition, proper
packaging is important. Like materials should be packaged together.
Carbon steel should not be mixed with stainless instruments. Plastic
instruments should be separated from metal instruments. Pouched
items should be separated on the tray and should only be one layer
deep. When using paper/poly bags the paper side should be down.
Using a Tuttnauer Pouch Rack will insure good air circulation and more
efficient drying .

11.5. Loading

1. Load the autoclave properly according to instructions in sec. 10.

 Be sure that instruments of dissimilar metal (stainless

steel, carbon steel, etc.) are separated (see sec. 10 #6).

 Observe maximum weight limits as referenced in the

table in sec. 3.3

 When sterilizing wrapped instruments it is recommended

that a pouch rack such as the TuttnauerTMPouch Rack

1

3

2

Page 89

be used to ensure proper steam penetration and
adequate drying when sterilizing pouched instruments.

 If a pouch rack is not available then the pouches need to

be laid out plastic side UP and only one layer deep on
each tray.

 When sterilizing cassettes in the EZ9Plus the cassettes

are loaded horizontally (see picture below).

Note: Pushing the bottom tray all the way back will cause it to

interfere with the chamber sensors.

 When sterilizing cassettes in the EZ11Plus they are

loaded vertically (see picture below). To adjust the rack
for vertical sterilization of cassettes, remove the trays
and gently squeeze the sides of the rack inward and at
the same time rotate the rack into a vertical position.

 When sterilizing textiles do not put the textiles on the

bottom tray.

Loading of heavy and diverse loads

When sterilizing heavy loads we recommend using a
TuttnauerTMPouch Rack. See the figures below showing

Page 90

examples of using a combination of trays and racks for
sterilizing heavy or diverse loads.
The EZ9Plus is supplied with 3 wire trays. The EZ11Plus is
supplied with 5 wire trays and 1 pouch rack.

NOTE: The EZ9Plus can accommodate 1 pouch rack and the
EZ11Plus can accommodate 2 pouch racks.

1. Ensure that the correct sterilization program is selected:

 Use the UP or DOWN keys to select the program to run.
 The program can only be changed when the door is

open.

2. If needed additional drying time can be added at this time (see
sec. 7.1.1).

3. Close the door by either:

 Holding the handle in the open position while pushing the

door until it comes to the closed position, then releasing
the handle.

 Pushing on the door handle and gently pushing the door

closed.

 When the door is properly closed the open door symbol

is then replaced by the message “System Ready”.

4. Start the cycle by pressing the START/STOP key.

Note: Pushing the bottom tray all the way back will cause it

to interfere with the chamber sensors.

Cycle Description

 The door is now locked

 “Water Filling” is displayed until the correct volume of water

has automatically filled the chamber.

 The autoclave starts performing the sequence of operations.

The actual measured values of pressure and temperature are
displayed continuously and printed (if the optional printer is
installed).

 The EZView display shows the current stage of the cycle. (See

sec. 5.1 ).

 In any program that has a drying stage scheduled, the dry

stage begins after the steam exhaust stage. The autoclave is
equipped with an air pump that during the drying stage draws
air through a HEPA filter (0.2 µm) and circulates that air
through the heated chamber and out the slow exhaust valve to
remove moisture and facilitate the drying operation. Drying is
performed with the door closed.

 At the end of a successful cycle, the screen shows the Cycle

Ended message and the door is automatically unlocked. The
slow exhaust valve is opened to prevent formation of a
vacuum.

 In the event of a program failure, the exhaust valve is opened

to release pressure from the chamber and a fail message is
displayed.

 There is a mandatory 1 minute of drying before the door can

be opened.

 When the mandatory drying is completed pressing the

START/STOP key will clear the error message and unlock the
door.

Extra Drying Time

If you see that additional drying is needed, with the door open select
Extra Drying Time, then close the door and press the Start/Stop button
to run the Extra Drying Time cycle (see sec. 6.7). The default additional
drying time is 5 minutes, however it can be altered by the user (see
sec. 7.1.1).

door:

 It is strictly forbidden to lean on the autoclave.
 It is strictly forbidden to place your hand or any part of

your body over the door.

Use the tray handle or wear heat-resistant gloves to
remove the load from the autoclave.

On completion of the cycle, the load shall be visually
inspected to ascertain that the load is dry, and that
sterilization indicators have made the required color
change.

Warning!

The sterility of the instruments processed in
unwrapped cycles cannot be maintained if exposed
to non-sterile environment.

If the symbol for “Water in the Chamber” appears on the
screen, the door will stay locked. This indicates that there is still

water in the chamber or that the water electrode, in the chamber,
needs to be cleaned. To open the door, see Emergency Door
Opening section 12.8

CAUTION! Bypassing the automatic door lock and forcing the

door open can result in water spilling out of the chamber.

11.7. Stopping the process manually

It is possible to stop the program while the autoclave is operating.
Pressing the START/STOP key at any stage of the process stops the
operation. Any cycle that stops prematurely is considered a failed cycle.

Page 93

WARNING! If the cycle was aborted before
completing the sterilization stage, it will leave the
load unsterilized. Handle it as a contaminated load.

 If the cycle is manually aborted before completing the sterilization

stage, the screen becomes yellow; a caution symbol is displayed
with the message "Cycle Failed” and an error message stating
the reason for the failure. (See sec. 5.3 ).

 If the cycle is manually aborted after the sterilization stage is

completed, the screen will remain white with the message

12. MAINTENANCE INSTRUCTIONS

12.1. Preventive and Scheduled Maintenance

The maintenance operations described in this chapter need to be
followed as indicated to keep the device in good working condition.
This maintenance schedule is the responsibility of the equipment owner
and not covered under the warranty.
The majority of instructions that follow can easily be carried out by the
operating personnel and do not require a service technician.
Should the need arise or the instructions in this section indicate,
technical assistance or a service technician can be requested by either
calling your dealer or Tuttnauer USA.

12.1.1. Daily

 Clean the door gasket and outside rim of the chamber with a

mild detergent, water and a soft cloth or sponge. The gasket
should be clean and smooth. Be sure to clean the inside and
outside of the gasket flap.

12.1.2. Weekly by the operator

 Once per week or after 20 cycles, clean and descale the

chamber, copper tubes and the reservoir using Chamber

BriteTM. Follow these instructions:

Cleaning Table Top Autoclaves with Chamber Brite™

CHAMBER BRITE™ is a cleaning and descaling agent designed
specifically for the cleaning and removal of water deposits, oxides and
other sediments that are found in steam sterilizers. The material is a
combination of acidic salts and additional cleaning materials.

Cleaning is an important part of maintaining your sterilizer.
Cleaning the autoclave chamber is a very simple, but important
procedure to keep your sterilizer operating properly.
If the autoclave is not cleaned regularly, dirt and debris will build up and
clog the tubing and valves.
This dirt can also be transmitted to the instruments during sterilization.
In addition, a layer of dirt on the stainless steel chamber traps moisture
against the metal and will lead to the chamber becoming porous and
failing.

Page 96

Cleaning Procedure

Items you will need to have on hand:

Chamber Brite™

 For EZ9Plus models use one packet of CHAMBER BRITE™.

 For EZ11Plus models use one packet of CHAMBER BRITE™.

Soft cloth or sponge
Drain hose (to drain water reservoir)
Pail (to drain reservoir water into)
Gloves
Nonabrasive stainless steel cleaner (for trays and tray rack)
Steam distilled water having the characteristics described in sec.

3.8.

Important!

Please remember:
NEVER use bleach, steel wool, a steel brush or anything abrasive
to scrub or clean the chamber, trays and tray holder.
Do NOT sterilize instruments during the chamber cleaning
process.
Before using Chamber Brite, the autoclave chamber MUST be
cold. If the chamber is hot, Chamber Brite will react and give off
an odor.
All steps in this procedure must be completed without
interruption.

1. When the autoclave chamber is cold, remove instruments
trays and the tray holder from the autoclave. Starting with a
hot chamber can result in burning of the Chamber Brite and
the release of a strong odor.

2. Open the door and spread the contents of one packet of
Chamber Brite™ in a straight even line along the bottom of
the chamber, from back to front. Do not leave a pile of
Chamber Brite in one spot.

3. Select the Chamber Brite Cleaning program, Close the door
and start the cycle.

4. At the end of the cycle open the door and drain the water
from the reservoir

5. Fill the reservoir with steam distilled water or mineral free
water only. Use only water having the characteristics

described in sec. 3.8.

Page 97

6 Repeat the Chamber Brite cleaning cycle, BUT without using

the Chamber Brite powder. This will remove any residue
from the internal plumbing.

7. At the end of the second cycle open the door and drain the
water from the reservoir.

8. Wipe the interior of the chamber with a damp cloth or
sponge to remove any residue.

Clean the water sensor in the rear of the chamber with a
damp cloth or sponge. Cleaning the dirt off the sides of the
sensor is more important than the tip. (see sec. 12.6 )

9. Fill the reservoir with steam distilled water or mineral free
water only. Use only water having the characteristics

described in sec. 3.8.

10. The autoclave is now ready to use.

IMPORTANT:
DO NOT sterilize instruments during the cleaning process!!!
CAUTION!

 Keep out of reach of children. Contains mildly acidic

ingredients. Avoid contact with the skin, eyes or
clothing. Wash hands well after touching the powder,
in the case of eye contact flush with continuous
running water for at least 15 minutes. If irritation
persists get medical attention. If large quantities of this

Page 98

material are swallowed, call a physician immediately. Do
not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an
unconscious person. If victim is conscious give water to
drink.
Note: If cleaning the chamber with Chamber
Brite is not possible then at a minimum follow
these two steps.

1. Once per week, drain the reservoir (see sec. 12.2)
and fill with steam distilled water or mineral free
water only. Use only water having the
characteristics described in sec. 3.8.

2. Clean the water sensor in the rear of the chamber
with a damp cloth or sponge. Cleaning the dirt off
the sides of the sensor is more important than the
tip. (see sec. 12.6).

 Clean the tray holder and trays with a non-abrasive

stainless steel cleaner and water, using a cloth or sponge.
You may use diluted Chamber Brite™ solution as cleaning
agent. To prepare this solution, pour one packet of
Chamber Brite™ into 32 ounces of warm mineral-free
water. Rinse the tray holder and trays immediately after
cleaning with clean water to avoid staining the metal. Wipe
dry with a cloth or paper towel.

CAUTION!
Do not use steel wool, steel brushes, bleach or any
cleaning agent containing bleach or anything abrasive to
clean the chamber, tray holder or trays. Doing so will
damage the chamber and trays!

 Put 1-2 drops of oil, such as 3 IN ONE Oil, on the door pins

and any moving parts of the door locking mechanism (See
the figure below).
