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.
Warning!
Mind the Power Socket. Keep it and its vicinity dry. Danger of
electrocution.
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. Do not place your hand or head, etc. above the door while opening, as hot
steam is escaping the chamber.
5. Do not stand near the back panel of the autoclave while operating, as the
pressure safety valve may release steam.
6. Do not touch hot surfaces, such as the top enclosure and area adjacent to
the chamber opening!
7. When withdrawing trays, use the enclosed tray handle or wear heat
resistant gloves.
8. To assure proper operation of the autoclave, avoid placing in the vicinity
of electrical equipment which is not certified for Electromagnetic
Compatibility according to IEC/EN 61326-1.
9. 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).
10. The door also remains locked if there is a cycle failure or the unit has no
power.
11. Open the door slowly to allow steam to escape.
12. Once a year, or more frequently, effectiveness tests must be performed,
i.e., calibration and validation.
13. 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.

7
14. Make sure there are no leaks, breaks, blockages, whistles, or strange
noises.
15. Perform maintenance operations as instructed. The owner of the
autoclave is responsible to perform the maintenance operations.
16. Notify the person in charge immediately of any deviation from the proper
function of the device.
17. Protective equipment and clothes and other safety instructions should be
implemented in accordance with local and national regulations and/or
rules!

3. TECHNICAL DATA
3.1 Introduction
This autoclave is an electrically heated sterilizer using steam as the
sterilizing agent. Acomputerized 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. The autoclave is
equipped with an air compressor that, during the drying stage draws air
through a HEPA filter (0.2
µ
m). It pushes the 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 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, 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, 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.
3.2 Standby Heating Mode
The autoclave provides an option of heating the chamber in standby
mode between cycles, at a very low power level, 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 model EZ10K and optional on
EZ9 and EZ10 models.
3.3 Environmental Emission Information
1. The peak sound level generated by the autoclave is less than 70 dBA
with background noise of 60 dBA.

9
2. The total heat per hour transmitted by the autoclave is < 100 Wh for
all models.
3.4 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 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.
Mains supply voltage fluctuations up to +/-10% 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!
