Intended use
This steam sterilizer is designed for application in a medical context, e.g. general practitioners and dental
practices. According to DIN EN 13060, this steam sterilizer is considered as a steam sterilizer with type B
cycles. As an 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 trans-
mission 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.
The steam sterilizer uses a separate steam generator to generate sterilizing steam. Steam is generated
upon program start and led into the sterilization chamber. This establishes a pre-defined pressure and
temperature. The sterilization chamber is protected against overheating. You can sterilize large quantities
of instruments or textiles directly one after each other, thereby achieving excellent drying results.
Automatic preheating
If preheating is activated, the cold chamber is heated up to the preheating temperature of the particular
program before program start, or this temperature is held between two program runs. This reduces pro-
gram times and reduces the accretion of condensation, thus improving drying results.
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 functionali-
ty 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.
Quantity and quality of the feed water
The quantity and quality of the feed water is automatically checked before every program start.

Program sequences
Regular sterilization program
A program runs in three phases: air removal, sterilization and 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 / the drying.
Program phase Description
1. Air removal phase
(fractionation)
The air removal phase comprizes the conditioning and the evacuation phase.
During conditioning, steam is repeatedly injected into the sterilization chamber to
generate over-pressure. The mixture of air and steam is then removed
repeatedly (evacuation). This procedure is also called the fractionated pre-
vacuum procedure.
2. Heating phase The heating phase follows the air removal phase. The continued steam
admittance into the chamber leads to an increase in pressure and temperature
which continues until the program-specific sterilization parameters have been
reached.
3. Sterilization phase If the pressure and temperature correspond to the program-dependent nominal
values, the sterilization phase begins. The sterilization time is indicated on the
display.
4. Pressure release The end of the sterilization phase is followed by pressure release with
simultaneous emptying of the steam generator.
5. Drying phase The sterilization material is dried using a vacuum (vacuum drying). The drying
phase begins after the pressure release. Upon program end, the chamber is
filled with sterile air via the air filter and adjusted to the ambient pressure.
6. Ventilation Once the program has come to an end, the chamber pressure is adapted to the
ambient pressure. The corresponding notification for ventilation is displayed.
Vacuum test
The vacuum test serves measurement of the leakage rate. No real sterilization is performed. The test is
performed with a cold, dry and unloaded device.
Program phase Description
1. Air removal phase
(evacuation)
The chamber is evacuated until the pressure for the vacuum test has been
reached.
2. Equilibration time An equilibration time of five minutes will follow.
3. Measurement time The measurement time amounts to ten minutes. The pressure increase within
the chamber is measured during the measurement time. The evacuation
pressure and the equilibration time or measuring times are shown on the
display.
4. Test end The display shows the test results, the batch number, the total number of
batches and the leakage rate.

Setup and installation
PLEASE NOTE
Comply with the specifications of the technical manual during set-up and installation.
This contains all building-side requirements.
Record of installation and setting up
The record of installation and setting up is to be completed by the responsible stockist and a copy sent to
MELAG as proof of the correct set-up, installation and initial commissioning. This is a constituent part of
any guarantee claim.
Feed water supply
Steam sterilization requires the use of distilled or demineralized water water, known as feed water.
DINEN13060 requires that feed water be used in accordance with the guideline values in appendix C.
The feed water supply is effected either via the internal feed storage tank or via a separate water treatment
unit (e.g. MELAdem 40/MELAdem 47). When using the internal storage tank for the feed water supply, it is
necessary to refill it periodically. The steam sterilizer will issue notification at the relevant time.
A water treatment unit is connected to the domestic water supply. It produces the feed water which the
steam sterilizer requires for steam generation. The use of a water treatment unit guarantees the availability
of sufficient feed water. There is no need to fill the feed water container manually.
Using the internal water storage tank
When feed water is supplied via the internal storage tank, this needs to be filled manually from time to
time. The steam sterilizer will issue notification at the relevant time.
The internal storage tank holds max. 4 l. This volume of feed water is sufficient for up to seven sterilization
runs.
The steam-generating system requires at least 1l of water to ensure the feed water supply.
}To fill the storage tank with fresh feed water remove the lid and fill the right-hand chamber of the
storage tank with fresh feed water up to the MAX mark.
Setting the feed water supply on the steam sterilizer
The INTERNAL function must be set in order to enable feed water supply via the internal storage tank. The
EXTERNAL function must be set in order to enable feed water supply via a water treatment unit.
1. Select the SETUP menu Function by pressing the '+' and '-' keys simultaneously. The display will
show the notification Function: Last batch number.
2. Navigate using the '+' or '-' key until the display shows: Function: Feed water supply.
3. Press the 'P' key. The display shows the option currently set.
4. Press the 'P' key again to change to the desired setting (INTERNAL/EXTERNAL).
5. Press the 'S' key to save the setting and to leave the menu.
