2. TECHNICAL DATA
2.1 Introduction
This table-top autoclave is designed for the 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. A computerized control unit ensuring a fully automatic sterilization cycle,
control and monitoring of physical parameters and a clear documentation of the
sterilization cycle controls the autoclave.
The autoclave has three automatic programs, according to the material to be
sterilized, and one auxiliary drying program. Models EA and EKA are equipped
with an air compressor that during the drying stage, draws air through a HEPA
filter (0.2µm.) and pushes that air through the heated chamber to remove moisture
and facilitate the drying operation. Drying is performed with the door closed.
On all models (except 1730), 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 regular operation of the pump.
The control system provides adequate protection, to ensure the safety of personnel
and reliable operation with a minimum of shut down time.
On all models (except 1730), a printer is an optional addition to the autoclave. The
printer prints the preset and actual parameters of the cycle (temperature, time and
pressure).
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
optimum effective results.
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.
2.2 Stand – by heating mode
The autoclave provides an option of heating the chamber in stand-by mode
between cycles with a very low power in order to reduce total cycle time (1.6% of
the total power only). The autoclave turns off automatically if the interval between
the sterilization cycles is more than 2 hours. This feature is standard on all EK,
EKA models and optional on all E, EA models.
2.3 Environment Emission Information
1. The peak sound level generated by the autoclave is less than 70 dBA with
background noise of 60 dBA.
2. The total heat per hour transmitted by the autoclave is < 100 Wh for all
models.

1. GENERAL
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 aclaim with the shipping carrier and also notify
Tuttnauer.
