2TECHNICAL DATA
2.1 Introduction
This E-Type table-top autoclave is designed for the sterilization of
medical and surgical solid instruments in dental, medical and
veterinary clinics, first aid rooms, laboratories etc.
Types E and EK are intended to sterilize non wrapped solid products.
Types EA and EKA are intended for sterilization of non-wrapped and
wrapped solid products.
The autoclave models E, EK, EA and EKA are electrically - heated
sterilizers of different dimensions, using steam as the sterilizing agent.
A computerized control unit ensuring a fully automatic sterilization
cycle and precise control and monitoring of physical parameters and a
clear documentation of the sterilization cycle controls the autoclave.
Five automatic programs are available, according to the material to be
sterilized. All sizes (except 1730) have a model that includes a drying
stage (EA and EKA). The difference between EK and EKA is the air
compressor that, during the drying stage, pushes filtered air (0.2µm.)
through the chamber to pull out the humidity, the dry operation 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 intensifies the water flow
into the chamber. 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.
All models (except 1730) are equipped with a pressure gauge that is
used as a guide only. Should there be a power failure during the
operation of the autoclave, the pressure gauge indicates to the operator
that there is pressure in the chamber. The accuracy is ±1.6%.
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/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 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. The stand-by feature is activated, as default, on cycles 1,
2, 3, 4 and not activated on cycle 5.

7
The company – qualified technician can cancel this feature on EK or
EKA models, or activate it on E and EA models, according to customer
requirements.
2.3 Operating Conditions
This device is for indoor use only!
The sterilizer should be loaded only with autoclavable material!
The environment shall not exceed an ambient temperature of 40ºC and
a relative humidity of 85% respectively.
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!

2.11 Water quality
2.11.1 Water for generation of steam
The distilled or mineral – free water supplied to the
autoclave should have the physical characteristics and
maximum acceptable level of contaminants indicated in the
table below:
Physical characteristics and acceptable contaminants
levels in water, for sterlizers
Evaporate residue <15 mg/l
Silica <2 mg/l
Iron <0.2mg/l
Cadmium <0.005 mg/l
Lead <0.05 mg/l
Rest of heavy metals <0.1 mg/l
Chloride <3 mg/l
Phosphate <0.5 mg/l
Conductivity <50 µs/cm
pH 6.5 to 8
Appearance colourless, clean, without sediment
Hardness <0.1 mmol/l
Compliance with the above data should be tested in
accordance with acknowledged analytical methods, by an
authorized laboratory.
Attention:
We recommend testing the water quality once a month. The
use of water for autoclaves that do not comply with the
table above may have severe impact on the working life of
the sterilizer and can invalidate the manufacturer’s
guarantee.
2.11.2 Reverse Osmosis
A Reverse Osmosis (RO) system may be used to improve the
quality of the water used to generate steam in the steam
generator.
In RO, the water is forced through a semi-penetrable
membrane, which filters out contaminants to a high degree
of efficiency. In deionisation (DI) ions and charged particles
are removed either by electric fields or by ion exchange in
resin beds.
Although the RO cannot normally attain the degree of purity
possible with the DI methods, it is more than adequate for
the feed water intended for clean-steam generators.
Moreover the RO has several advantages:

12
1. RO is cheaper to install and to run than DI.
2. RO removes particulate matter, organic molecules and pyrogens
that DI cannot remove
3. RO water is less corrosive to steel and copper than DI water.
4. RO maintenance requirements are less demanding than those of
the DI units.
Therefore the use of mineral free water will contribute to better
performance and longer life of the autoclave.

♦Fast exhaust; steam is exhausted out of the chamber at a fast rate
until pressure drops to atmospheric pressure.
♦Drying; heating of chamber for 30 min. at a reduced power.
Venting the chamber with a pump (on EA, EKA model).
Notes:
1. On E, EK models the door shall be opened to reduce drying time.
2. On EA, EKA models the drying stage is performed with a closed
door. Filtered air is pumped into the chamber to ventilate the
chamber during the drying stage.
3. After operating the sterilizer, brown stains might appear on the
bottom of the chamber. These stains are a result of the heating
elements that are located at the lower external part of the chamber.
The brown color is a common phenomenon, can be easily be
removed, and will not have any effect on the steriliszed goods.

♦Sterilization time: 30mins.
♦Dry time: 30mins.
Operations Sequence
♦Steam is generated by electric heating elements heating the water
until the sterilization temperature is reached.
♦Fast exhaust; steam is exhausted out of the chamber at a fast rate
until pressure drops to atmospheric pressure.
♦Drying; heating of the chamber 30 mins. at a reduced power.
Venting the chamber with a pump (on EA, EKA model).
Note:
1. On E, EK models the door shall be opened to reduce drying time.
2. On EA, EKA models the drying stage is performed with a closed
door. Filtered air is pumped into the chamber to ventilate the
chamber during the drying stage.
3. After operating the sterilizer, brown stains might appear on the
bottom of the chamber. These stains are a result of the heating
elements that are located at the lower external part of the chamber.
The brown color is a common phenomenon, can be easily be
removed, and will not have any effect on the steriliszed goods.
Attention:
The sterility of instruments processed in unwrapped cycles
cannot be maintained if exposed to non-sterile environment.
