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
theycan filea claim with theshipping 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.
1.2 Warranty
We certify that this instrument is guaranteed to be free from defects in
material and workmanship for two years against faulty components and
assembly.
This warranty does not include routine cleaning and preventive
maintenance to be performed according to instructions in
section 9.1 (Preventive and Scheduled Maintenance).
Tuttnauer warrantees all new autoclaves for a period of two full years,
covering both parts and labor. This two year warranty covers defects in
materials and workmanship on every part in the autoclave except door
gaskets and HEPA filters (they are wear items).
Tuttnauer warrantees all chambers for a period of ten (10) years against
defects in materials and workmanship. This chamber warranty went into
effect January 1997.
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.
The Autoclave should only be used in a manner described in this
manual!
1.3 Warranty Statement
To activate the warranty, the registration card must be completed and
returned to Tuttnauer within fourteen (14) days of purchase or you may call
our customer service department at the number listed below.
No product will be received or accepted for repair without prior return
authorization from Tuttnauer. All transportation charges to and from
Tuttnauer must be paid by the owner of the autoclave. During the first 90
days after purchase of an autoclave, Tuttnauer will pay shipping costs on
an individually evaluated basis and ONLY with pre-approval.

Note:
If you have any questions or there are any difficulties with this instrument
and the solution is not covered in this manual, please contact your dealer or
Tuttnauer USA Co. Do not attempt to service this instrument yourself.

2 TECHNICAL DATA
2.1 Introduction
This tabletop 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). It 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 shutdown 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 Standby Heating Mode
The autoclave provides an option of heating the chamber in standby
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 Environmental 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.

2.4 Operating Conditions
This device is to be used for indoor use.
This autoclave is intended for NORMAL environment conditions as
follows:
Altitude up to 2000m.
Room temperature range 41ºF to 104ºF (5ºC to 40ºC).
Installation Category II.
Pollution Degree 2.
Maximum relative humidity 80% for temperature up to 31ºC decreasing
linearly to 50% relative humidity at 40ºC.
Main supplyvoltage fluctuations up to +/-5% of the nominal voltage.
The sterilizer should be loaded only with autoclavable material.
Caution!
Waste water should be brought into the public net in accordance
with the local rules or requirements, i.e.
ONLY NON-HAZARDOUS LIQUIDS SHALL BE DISPOSED IN
PUBLIC SEWAGE!

(3) Glassware (slow exhaust, no drying)
Pressing one of the above program keys determines the chosen
program. The program parameters are displayed and the
program indicator lights.
(4) Dry Only
Pressing this key allows inclusion of the Additional Drying
procedure for a period of time determined by the operator. Time
range is 0-99 minutes.
3.2.2 Other keys
(5) TEMP.
Pressing this key places the marker under the temperature
displayed on the display. To raise or lower the program
sterilization temperature, press UP or DN keys. To store the
new value in the memory, as the nominal setting, complete the
changing of the parameter by pressing TEMP. key again. The
permitted temperature range for proper sterilization is 250ºF-
274ºF (121ºC-134ºC).
Note:
In no case should the temperature be set higher than 274ºF
(134ºC)
(6) STE. TIME
Pressing this key places the marker under the sterilization time
displayed on the display. To raise or lower the program
sterilization time, press the UP or DN keys. To store the new
value in the memory, as the nominal setting, complete the
changing of the parameter by pressing STE. TIME key again.
Time range is 3-99 minutes.
Note:
It is important to properly coordinate the STE. TIME
with the sterilization temperature.
(7) DRY TIME
Pressing this key places the marker under the drying time
displayed on the display. To raise or lower the program drying
time, press the UP or DN keys. To store the new value in the
memory, as the nominal setting, complete the changing of the
parameter by pressing DRY TIME key again. The time range is
0-99 minutes. This key does not allow any change of the dry
time for the glassware program, for which it is permanently set
to 00 minutes.
(8) UP
Pressing this key in combination with TEMP. (5), STE TIME
(6), DRY Time (7) and CLOCK (9) increases these values.
