1General
Caution!
Read the Operating Instructions carefully, before beginning any
operation on the autoclave!
1.1 Incoming Inspection
Upon receiving your Tuttnauer Autoclave, carefully inspect the outside of the
shipping carton for signs of damage. If any damage to the carton is found, note
the location with respect to the autoclave and check that area of the autoclave
carefully once it is fully unpacked. Observe packing method and retain packing
materials until the unit has been inspected. Mechanical inspection involves
checking for signs of physical damage such as: scratched panel surfaces,
broken knobs, etc.
If any damage is found, contact your dealer as soon as possible so that
they can file a claim with the shipping carrier and also notify Tuttnauer.
All Tuttnauer products are carefully inspected prior to shipment, and all
reasonable precautions are taken in preparing them for shipment, to assure
safe arrival at their destination.
Note: Lifting and carrying should always be done by two people.

maintenance to be performed according to instructions in
sec. 12.1 (Preventive and Scheduled Maintenance).
Tuttnauer warrantees all new autoclaves for a period of one full year, covering
both parts and labor. This one year warranty covers defects in materials and
workmanship on every part in the autoclave except the HEPA filter and the
door gasket.
This warranty does not apply to any instrument that has been subjected to
misuse, neglect, accident or improper installation or application, nor shall it
extend to autoclaves that have been repaired or altered outside the factory
without prior authorization from Tuttnauer.
Tuttnauer’s obligation is limited to the repair or replacement of parts for the
autoclave. This warranty will be void if the unit is not purchased from an

authorized Tuttnauer dealer. No other warranties or obligations are expressed
or implied.
Warning
Only United States Food and Drug Administration cleared accessories
such as sterilization wraps, sterilization pouches, chemical indicators,
biological indicators, and sterilization cassettes should be used with this
autoclave. Sterilization programs 1,2,3,4,5,6,7 and 8 are not considered by
the Food and Drug Administration to be standard sterilization cycles.
There are currently no sterilization wraps, sterilization pouches, chemical
indicators, biological indicators, or sterilization cassettes cleared for use
by the Food and Drug Administration for the specific sterilization
parameters of sterilizer programs 1,2,3,4,5,6,7 and 8.
The Autoclave should not be used in a manner not described in this
manual!
1.3 Warranty Statement
The warranty registration must be completed and returned to our service
departments; within fourteen (14) days of purchase or the warranty will be void. Our
European Representative’s Technical Service Department can be reached at:

Note: If there is any difficulty with this instrument, and the solution is not
covered in this manual, contact our representative or us first. Do not attempt to
service this instrument yourself. Describe the difficulty as clearly as possible so
we may be able to diagnose the problem and provide a prompt solution.
Send along a copy of the last printout for our inspection. If replacement parts
are needed, stipulate the model and serial number of the machine.
No autoclaves will be accepted for repair without proper authorization from us.
All transportation charges must be paid both ways by the owner.

2Safety Instructions
The autoclave has unique characteristics. Please read and understand this
technician manual before first operation of the autoclave.
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. Before use, check inside the autoclave chamber to ensure that no items
have been left from the previous cycle.
3. Load trays in such a way as to allow steam to move freely among all
items.
4. When sterilizing plastic materials, make sure that the item can withstand
sterilization temperature. Plastic that melts in the chamber is liable to
cause a great deal of damage.
5. On closing the device door, make sure it is properly locked before
activating. Verify that DOOR OPEN symbol is replaced by the
message "System Ready".
6. Verify once again that you have chosen the appropriate sterilization
program.
7. Open the door slowly to allow steam to escape and wait 1 minute before
you remove the load.
8. When removing the trays it is recommended to use the tray handle or
wear heat resistant gloves.
9. Once a month, ensure that the safety valve is operating.
10.A certified inspector must perform a periodic pressure chamber safety
test according to the local regulations.
11.Once annually, or more frequently, effectiveness tests must be
performed, i.e., calibration and validation.
12.Make sure there are no leaks, breaks, blockages, whistles or strange
noises.
13.Perform maintenance operations as instructed. The owner of the
autoclave is responsible to perform the maintenance operations.
14.Notify the person in charge immediately of any deviation from the
normal functioning of the device.
15.Protective equipment and clothes and other safety instructions should
be implemented in accordance with local and national regulations and/or
rules!

3General Information
3.1 Intended Use
This table-top autoclave is designed for sterilization of medical and surgical
goods such as unwrapped and wrapped, solid, hollow, porous products and
tubes in ophthalmic, dental and medical clinics, first aid rooms, small
laboratories etc.
3.2 Introduction
This autoclave model is an electrically heated sterilizer using steam as a
sterilizing agent.
The autoclave is designed as Type B in accordance with EN13060.
This model is a prevacuum sterilizer having the following features;
An air removal stage (prevacuum), before starting the sterilizing stage.
A post-sterilization drying phase, based on the combined operation of
heat and vacuum with air inlet pulses.
There are the following safety devices installed in the autoclave to optimize its
safe operation:
Two safety thermostats, to prevent over-heating of the steam generator
and the chamber.
Two safety pressure valves to prevent over pressurizing the steam
generator or the chamber.
A digital display is used for monitoring and control purposes. This device
displays the pressure in kPa, psia or psig, according to the operator’s
needs. The pressure is displayed for both the pressure in the chamber
and the pressure in the steam generator.
Temperature can be displayed in either °F or °C according to the
operator’s needs.
The advantages of the prevacuum sterilizer are as follows:
Removal of residual air from packs and porous load and most kinds of
tubes (rubber, plastic etc.) by vacuum at the first stage of the cycle.
More efficient steam penetration into the load; assuring effective
sterilization.
Improved temperature uniformity throughout the chamber.
Better drying of materials due to the vacuum achieved in the chamber
during the drying cycle.
The printer prints the preset and actual parameters of the cycle (temperature,
time and pressure/vacuum).
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.
