Chapter 1 – Performance Specification
In this chapter you learn
under which conditions and for which purpose you should use this autoclave
what benefit you can achieve by using this autoclave
which sterilization programs you can use
Proper use
Application area The autoclave is intended for use in the medical field, e.g. in general
physician and dental practices.
Sterilization tasks According to →DIN EN 13060 this autoclave is considered a Class B
sterilizer. It is suited as a universal autoclave for demanding sterilization
tasks. For instance, you can sterilize narrow-bore instruments and
transmission instruments – wrapped or unwrapped – and larger quantities
of textiles.
Dange
r
Observe the following instructions for using the autoclave:
■Do not sterilize any liquids with this autoclave. It is not approved for
the sterilization of liquids.
In case of non-observance, the consequences could be →delayed boiling,
damage to the autoclave and burns.
Attention ■Use the autoclave only for the intended purposes outlined in the
related technical documents and only in connection with the devices
and components recommended by MELAG.
■The sterilization of instruments and textiles with this autoclave, like the
foregoing instrument sterilization, is only to be done by competent
personnel.
■Only use instruments, wrappings and textiles which are suitable for
steam sterilization according to the manufacturer's information.
In case of non-observance the consequences can entail damage to the
autoclave and/or to the →items to be sterilized.
User benefit
Universal use The autoclave sterilizes on the basis of the →fractionated vacuum
method. This ensures the complete and effective wetting or penetration of
the →items to be sterilized with saturated steam. This method makes it
possible to sterilize all kinds of loads which occur in a physician's medical
practice.
Large quantities
Small time expenditure
No pause times
Overheating protection
To generate the sterilization steam, the autoclave uses a →double jacket
steam generator. Once heated up, it provides permanent steam. The walls
of the →sterilization chamber thus have a defined temperature. The
sterilization chamber is protected from overheating and you can
consecutively sterilize large quantities of instruments or textiles very
rapidly and achieve excellent drying results.
Clean feed wate
r
The autoclave works with a one-way feed water system. This means that it
uses fresh purified →feed water for every sterilization run. The quality of
the feed water is constantly monitored via integrated →conductivity

Chapter 1 – Performance Specification
4
measurement. This prevents stains on instruments and soiling of the
autoclave, assuming the instruments have been carefully prepared.
Automatic feed water suppl
y
The supply with purified →feed water for the steam production is
automatically provided from an internal supply tank or a water treatment
unit (e.g. MELAdem®40, MELAdem®47).
Optimal drying for wrappe
d
items to be sterilize
d
The →items to be sterilized are dried by the →vacuum. (→vacuum
drying). This way you achieve optimal drying results for wrapped objects
as well.
Optimized total operatin
g
time
The autoclave works with an →electronic parameter control. This way the
autoclave optimizes the total operating time of a program depending on
the load.
High degree of safety b
y
extensive safety devices
The autoclave checks the pressure and temperature in the sterilization
chamber at all times and does not permit the door to be opened in case of
overpressure in the chamber. The motor-operated automatic door lock
opens the door by slowly turning the locking spindle and holds the door
while it opens. Pressure compensation takes place even if there is any
difference in pressure until the door is completely opened.
The quantity and quality of the →feed water is checked.
A →process evaluation system is integrated in the electronics of the
autoclave. During a program it compares such process parameters as
temperatures, times and pressures with each other. It monitors the
parameters with respect to their limit values at activation and control and
guarantees a safe and successful sterilization.
A monitoring system checks the device components of the autoclave with
respect to their functional reliability and their plausible interaction.
If one or more parameters exceed defined limits, the autoclave issues
warnings or error messages, and if necessary aborts the program. In the
event of an automatic program abort, observe the information on the
display.
Additional function chec
k
You can conduct an additional function check at any time with the help of
test programs.
Use the vacuum test to check the autoclave for leaks in the steam system.
Use the →Bowie & Dick test to check whether there is sufficient steam
penetration for porous material to be sterilized (e.g. textiles).
Effective batch
documentation
The autoclave has an internal log memory. All data of the completed
sterilization programs are automatically stored here.
You can read out the internal log memory immediately after the end of the
program, or at a later time. You determine whether the logged data are
issued to one or several different output media (e.g. log printer
MELAprint®42, MELAflash CF card, computer).

With the MELAdest®65 distilling unit, you can produce →feed water in the
practice cost effectively.
Feed water with wate
r
treatment uni
t
A water treatment unit is connected to the drinking water grid. It produces
the →feed water required for generating the steam for the autoclave. The
purified feed water connection for the autoclave is directly connected to
the water treatment unit.
If you use a water treatment unit, then there is always sufficient feed water
available. You no longer need to fill the water storage tank.
Water treatment units
MELAdem®40 an
d
MELAdem®4
7
The water treatment units MELAdem®40 and MELAdem®47 produce the
optimal purified feed water quality for the autoclave. The selection of the
respective unit depends on the number of sterilizations per day and the
respective loads. Every MELAG autoclave can be supplemented with a
water treatment unit.
Notice Please first consult with MELAG if you would like to use water treatment
units from other manufacturers.

should be 30% to 60% and the ambient temperature 16° to 26 ˚C.
Attention ■Without fail, keep the specified distance free to the surrounding
surfaces at the sides and above the autoclave.
Non-observance can lead to heat accumulation. This could adversely
affect the function of the autoclave and entail the shorting of the service
life of the vacuum pump and extended program times.
Distance to the surroundin
g
surfaces
The distance of the autoclave to the surrounding surfaces must be at least
5 centimetres on both sides and 10 centimetres at the back side. The
autoclave should be freely accessible from above, so that the built-in
supply tank can be filled and a good ventilation is guaranteed.
