1. GENERAL
Read the Operating Instructions carefully, before beginning any
operation on the autoclave!
1.1. Incoming Inspection
The autoclave should be unpacked and inspected for mechanical
damage upon receipt. 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 damage is apparent, contact your dealer or point of purchase, so that
they may notify the manufacturer and file a claim with the appropriate
carrier.
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.
1.2. Warranty
We certify that this instrument is guaranteed to be free from defects in
material and workmanship for one year against faulty components and
assembly with the exception of the heaters.
The warranty does not include and does not replace routine
treatment and preventive maintenance to be performed according
to instructions in paragraph 11. (Preventive and Scheduled

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.
If the autoclave is equipped with a printer, send along a copy of the last
printout for our inspection. If service or replacement parts are needed,
contact the dealer or our Technical Service Department. in your call
stipulate the model (written on the front) and the serial number of the
machine (written on the left side).
No products will be accepted for repair without proper authorization
from us. All transportation charges must be paid both ways by the
owner. This warranty will be void if the unit is not purchased from an
authorized full service Tuttnauer dealer.

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 guidance provided by the manufacturer: how to operate
the autoclave, the door safety mechanism, and the hazards involved in
circumventing safety means and how to select an adequate sterilization
program.
Make sure that you know where the main power switch is located.
Autoclave maintenance is crucial for the safe and effective function of the
device.
The daily B&D test, at the beginning of the working day, is part of the
preventive maintenance plan, along with the annual validation of the
sterilization processes that ensures appropriate sterilization conditions.
Never use the autoclave to sterilize liquids since it is not designed to sterilize
liquids.
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 away 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. Individual glass bottles shall be placed on a tray.
6. On closing the device door, make sure it is properly locked before
activating. Verify that DOOR OPEN symbol is replaced by the load
number.
7. Verify once again that you have chosen the appropriate sterilization
program.
8. Before withdrawing trays, wear heat resistant gloves.
9. Before opening the door, verify that there is no pressure in the chamber
(chamber pressure is displayed on the screen).
10. Open the door slowly to allow steam to escape and wait 1 minute before
you remove the load.
11. Once a month, ensure that the safety valve is operating, and once a year
certified inspector must perform pressure chamber safety test.
12. Once annually, or more frequently, effective tests must be performed, i.e.,
calibration and validation.
13. Make sure there are no leaks, breaks, blockages, whistles or strange noises.
14. Perform maintenance operations as instructed. The owner of the
autoclave is responsible to perform the maintenance operations.
15. Notify the person in charge immediately of any deviation or risk for the
proper function of the device.
16. 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. 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 goods that are defined as hollow A 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 and
ST55.
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 following safety devices installed in the autoclave to
optimize the safety operation:
1. Two thermostats, for over-heating of generator and the chamber.
2. Two safety pressure valves for generator and chamber.
An absolute digital display is used for monitoring and control
purposes. This device displays the pressure in kPa or in psi, according
to the operator’s requirement, and the absolute zero is displayed as “0”.
This displayed pressure indicates the pressure in the chamber.
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.
•Better drying of materials due to the vacuum achieved in the
chamber at the end of the sterilization 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.
Before operating this autoclave read carefully the 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.
Only technical personnel having proper qualifications and holding
technical documentation (including a Technician Manual) and
adequate information are authorized to service the apparatus.
