3 Performance specifications
Intended use
This steam sterilizer is designed for application in a medical context, e.g. general practitioners and dental
practices. According to EN 13060, this steam sterilizer is considered as a steam sterilizer with type B cy-
cles. As a universal steam sterilizer, it is suited to highly-demanding sterilization tasks. It can be used for a
range of tasks such as the sterilization of large quantities of instruments with narrow lumen and transmis-
sion instruments - both wrapped or unwrapped - and of textiles.
WARNING
Any attempt to sterilize liquids can result in a delay in boiling. This can result in burns
and damage to the device.
nNever use this device to sterilize fluids. It is not licensed for the sterilization of fluids.
Sterilization procedure
The steam sterilizer sterilizes on the basis of the fractionated vacuum procedure. This guarantees the
complete and effective wetting/penetration of the sterilization material with saturated steam.
This procedure enables the sterilization of loads common to a doctor's practice.
The steam sterilizer uses the double-jacket technology to generate the sterilization steam, i.e. the steam
sterilizer is fitted with a separate steam generator combined with a double-walled sterilization chamber. Af-
ter heating, steam is held constantly available in the double-jacket. This gives the walls of the steriliza-tion
chamber a defined temperature and protects the sterilization chamber from overheating. This especially ef-
fective procedure supports the quick evacuation of the air from the sterilization chamber, the sterilization
packaging and instrument cavities. This permits the sterilization of large quantities of instruments or tex-
tiles directly one after each other, thereby achieving excellent drying results.
Type of the feed water supply
The steam sterilizer works with a one-way feed water system. This means that it uses fresh feed water
(demineralized or distilled water) for every sterilization procedure. The quality of the feed water is subject
to permanent monitoring via integrated conductivity measurement. If combined with careful preparation of
the instruments, this serves largely to prevent stain accretion on the instruments and soiling of the steam
sterilizer.
Safety equipment
Internal process monitoring
A process evaluation system is integrated in the electronics of the steam sterilizer. It compares the process
parameters (such as temperature, time and pressure) during a program run. It monitors the parameters in
terms of their threshold values during control and regulation and guarantees safe and successful
sterilization. A monitoring system checks the device components of the steam sterilizer for their
functionality and their plausible interaction. If one or more parameters exceeds pre-determined threshold
values, the steam sterilizer issues warnings or malfunction messages and if necessary, aborts the
program. In the case of a program abort, follow the instructions on the display.
The steam sterilizer uses an electronic parameter control. This enables the steam sterilizer to optimize the
total operating time of a program in dependence on the load.
Door mechanism
The steam sterilizer constantly checks pressure and temperature in the sterilization chamber and prevents
the door from being opened when over-pressure has built up in the chamber. The motor-driven automatic
door locking mechanism opens the door slowly by turning the locking spindle. This also holds the door

whilst it opens. Pressure compensation will have been performed by the time that the door is completely
open, even following pressure differences.
Quantity and quality of the feed water
The quantity and quality of the feed water is automatically checked before every program start.

Program sequences
A program runs in three main phases: the air removal and heating up phase, the sterilization phase and
the drying phase. After program start, you can follow the program run on the display. It shows the chamber
temperature and pressure as well as the time until the end of sterilization / drying.
Program phases of a standard sterilization program
Program phase Description
1. Air removal and heating
up phase
Air removal
The air removal phase comprises the conditioning and the evacuation.
During conditioning, steam is repeatedly injected into and removed from the
sterilization chamber. This generates over-pressure and the residual air is
removed. Then, during fractionation, the mixture of air and steam is
evacuated from the sterilization chamber and steam is injected. This
procedure is also called the fractionated pre-vacuum procedure.
Heating
The continued steam injection into the chamber leads to an increase in
pressure and temperature which continues until the program-specific
sterilization parameters have been reached.
2. Sterilization phase Sterilizing
If the pressure and temperature correspond to the program-dependent
nominal values, the sterilization phase begins. The corresponding process
parameters (pressure and temperature) are held at sterilization level. The
sterilization time (holding time) is indicated on the display.
3. Drying phase Pressure release
The sterilization phase is followed by pressure release from the sterilization
chamber.
Drying
The sterile material is dried using a vacuum (vacuum drying).
Ventilation
Upon program end, the chamber is filled with sterile air via the air filter and
adjusted to the ambient pressure. The corresponding display
notificationVentilation is displayed.
Program phases of the vacuum test
Program phase Description
1. Evacuation phase The chamber is evacuated until the pressure for the vacuum test has been
reached.
2. Equilibration time An equilibration time of 5 min will follow.
3. Measurement time The measurement time amounts to 10 min. The pressure increase within the
chamber is measured during the measurement time. The evacuation
pressure and the equilibration time or measuring time are shown on the
display.
4. Ventilation The chamber is ventilated after the end of the measuring time.
5. Test end The display shows the test result, the batch number, the total number of
batches and the leakage rate.

Feed water supply
Steam sterilizer requires the use of distilled or demineralized water, known as feed water. Annex C of
EN13060 specifies the guideline values to be observed.
The steam sterilizer requires c. 3 l feed water for the first filling of the steam generator.
The feed water supply is effected either via the internal feed water tank or via a separate water treatment
unit (e.g. MELAdem40 / MELAdem47). The used feed water, so called waste water is either collected in
the internal storage tank on the waste water side (left) and emptied manually or disposed of automatically
via a building-side waste water connection.
NOTICE
When connecting an external feed water supply it is necessary to connect an external
wastewater outflow as well.
There is a risk that hot wastewater might run through the emergency overflow.
