Intended use
The steam sterilizer is designed for use in a general medical environment in which the instruments used
and their packaging do not require a class B steam sterilizer.
According to DIN EN 13060, this steam sterilizer is a Class S sterilizer. As a universal steam sterilizer, it is
suitable for the sterilization of unwrapped or wrapped solid instruments, hollow body articles and smaller
quantities of textiles.
WARNING
Any attempt to sterilize liquids can result in a delay in boiling. This can result in damage
of the steam sterilizer and burns.
nNever use this steam sterilizer to sterilize any fluids. It is not licensed for the sterilization of
fluids.
NOTICE
Failure to comply with these safety instructions can result in damage or can compromise
safety.
nOnly ever use the steam sterilizer for the applications as foreseen in the technical
documentation and only in connection with the devices and components as recommended
by MELAG.
nAs with the preceding instrument decontamination and in accordance with §2 MPBetreibV,
the sterilization of instruments and textiles using this steam sterilizer may only be carried out
by competent personnel.
nWhen conducting sterilization procedures, only use instruments, packaging and textiles
which the manufacturer has cleared for steam sterilization.
Sterilization procedure
The steam sterilizer sterilizes on the basis of the fractionated flow procedure.
This guarantees the complete and effective wetting/penetration of the sterilization material with saturated
steam.
The steam sterilizer uses integrated steam generation to generate sterilizing steam. Steam is generated in
the sterilization chamber upon program start. This establishes a pre-defined pressure and a set
temperature. The sterilization chamber is protected against overheating. You can sterilize instruments or
textiles directly one after each other, thereby achieving excellent drying results.
Automatic preheating
Activation of the preheating function pre-heats the cold chamber or holds it at a specific temperature
between two sterilization runs. This reduces program times and reduces the accretion of condensation,
thus improving drying results.

Type of the feed water supply
The steam sterilizer works with both a one-way feed water system and following the feed water circulation
system. The one-way feed water system uses fresh demineralized or distilled feed water for every
sterilization procedure. The quality of the feed water is subject to permanent monitoring via integrated
conductivity measurement. If combined with instrument decontamination of the instruments, this serves
largely to prevent stain accretion on the instruments and soiling of the steam sterilizer. When using the
feed water circulation system, the steam sterilizer saves water, as the feed water is used for multiple
sterilization cycles. The quality of the feed water is subject to permanent monitoring via integrated
conductivity measurement.
Automatic feed water supply
The supply with feed water for steam generation is performed automatically via an internal storage tank or
a water treatment unit (e.g. MELAdem40, MELAdem47). The technical manual provides detailed
information regarding connection to a water treatment unit.
Safety equipment
Internal process monitoring
An 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 warning 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.

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.
Table2: Phases of a sterilization program
Program phase Description
1. Air removal phase The fractionated flow procedure removes the air from the chamber through
pulsing repeated steam injection and removal. Depending on the program
selected and the current chamber temperature upon program start, further
fractionation can also follow.
2. Heating phase The heating phase follows the air removal phase. The pressure and temperature
increase 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.
5. Drying phase The drying phase begins after the pressure release.

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 setup
The record of installation 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. The internal
storage tank holds 5 L and is sufficient for up to 7 sterilization runs in a one-way system. The used feed
water, so called wastewater is either collected in the internal storage tank on the wastewater side (left) and
emptied manually or disposed of automatically via a building-side wastewater connection.
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. 5 litres. This volume of feed water is sufficient for up to seven
sterilization runs.
The feed water supply must be switched on. The steam-generating system requires at least one litre of
water.
}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
shows Function: Last batch number
2. Navigate using the '+' or '-' keys until the display shows: Function: Feed water supply.
3. Press the ‘P’ button. 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.
