3 Performance specifications
Intended use
The steam sterilizer is designed for use in a general medical environment in which the instruments used and their pack-
aging do not require a type B steam sterilizer with cycles.
According to }EN 13060, this steam sterilizer is a type S cycle sterilizer. As a universal steam sterilizer, it is suitable for
sterilization of unwrapped/single-wrapped solid instruments, simple hollow items and dental transmission instruments1).
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.
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.
nLike the preceding instrument reprocessing, the sterilization of instruments with this steam sterilizer (in
Germany according to §2 }MPBetreibV) may only be carried out by }competent personnel.
nOnly use instruments and packaging which are suitable for steam sterilization according to the
manufacturer's information.
Sterilization procedure
The steam sterilizer sterilizes on the basis of the fractionated flow procedure.
This guarantees the complete and effective wetting/penetration of the }load with saturated steam.
The procedure can be used to safely and quickly sterilize single wrapped instruments.
The steam sterilizer uses integrated steam generation to generate sterilizing steam. The sterilization chamber is protect-
ed from overheating and you can sterilize instruments in a short time.
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 program times and the accretion of
condensation, thus improving drying results.
Drying
The load is dried with the pulsating overpressure drying method. This way you achieve optimal drying results for wrapped
instruments as well.
Type of the feed water supply
The steam sterilzer works with a feed water one-way 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 a proper preparation of the instruments, this serves largely to
prevent stain accretion on the instruments and soiling of the steam sterilizer.
1) Further information is provided in the certificate of suitability (enclosed).

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 interplay. 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 optimise 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.
Quantity and quality of the feed water
The quantity and quality of the }feed water is automatically checked before every program start.
Performance characteristics of sterilization programs

Program sequences
Regular sterilization program
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 and drying.
Program phase Description
1. Air removal phase The fractionated flow procedure removes the air from the sterilization 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.
2) Further information is provided in the certificate of suitability (enclosed).

Program phase Description
3. Sterilization phase The sterilization phase begins as soon as the pressure and temperature correspond to the
program-dependent nominal values. 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.

Water stop For insurance reasons, MELAG recommends the installation of a water stop with a cut-off
valve (e.g. from MELAG), as the MELAdem 40 / MELAdem 47 are under constant hydraulic
pressure from the domestic water supply.
Compressed air connection (only MELAquick 12+)
A compressed air connection is provided for MELAquick 12+.
The externally provided compressed air must meet the following conditions:
nDried, free of condensate and filtered with a filter unit ≤ 2 µm
nPressure range 3-8 bar (43.5-116 PSI)
nFor hose lengths greater than 4m the minimum pressure must be 4 bar (58 PSI)
nStandard volume flow 10 l/min; this is removed from the supply only during drying
For the connection of the compressed air hose, different manifolds and coupling plugs are available as optional accesso-
ries, see Accessories and spare parts [}page68].
WARNING
If the steam sterilizer is operated without a compressed air supply, it is not conform to EN13060
because of the missing drying function. The steam sterilizer no longer accords with the intended
purpose outlined in the user manual.
nIf the device is to be operated without a compressed air supply, then have the stopper set included with the
device to deactivate drying installed by an authorised customer services / stockist technician before
commissioning.
NOTICE
According to EN ISO 7396-1, the steam sterilizer may not be connected to the supply network for
medical compressed air, e.g. medical air technology.
