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. The autoclave is
equipped with an air compressor that, during the drying stage draws air
through a HEPA filter (0.2µm). 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, 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 model EZ10K and optional on
EZ9 and EZ10 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 5ºC to 40ºC.
♦ Installation Category II.
♦ Pollution Degree 2.
♦ Maximum relative humidity 0% 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!
