Leakage water detector For insurance reasons, we recommend the installation of a leakage water
detector with a cut-off valve (e.g. a MELAG water stop), as the MELAdem 40 /
MELAdem 47 are under constant water pressure from the domestic water
supply.
PLEASE NOTE
The wastewater hose must be fitted at a constant decline without sagging. Deviations to
the installation arrangements require consultation with MELAG.
Failure to do so can result in malfunctions of the steam sterilizer.
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 supply with feed water is effected via an external water storage container, which must be filled
periodically with water of the corresponding quality, either manually or automatically via a water treatment
unit (e.g. MELAdem40 / MELAdem47).

Switching on the steam sterilizer
ü The steam sterilizer is connected to the electricity supply.
}The steam sterilizer is switched on at the power switch.
The display switches between the initial state and the notificationUnlock door with '+' key, if the
door is closed.
PLEASE NOTE
All accessories must be removed from the chamber directly after the steam sterilizer has
been switched on for the first time and before initial commissioning.
After activation of the device, a heating up time of c. 5 minutes (Vacuklav24B+) or c. 3 minutes
(Vacuklav30B+) is required depending on the device type. This time is required for the pre-heating. A
program will be started only after the target temperature has been reached.
PLEASE NOTE
When switching off the device via the power switch, wait three seconds before switching
it back on.
Preparing the sterilization material
Cleaning and disinfection must always have been performed before sterilization. Only in this way is it
possible to guarantee the subsequent sterilization of the sterilization material. The materials used, the
cleaning fluid and treatment procedures used are of decisive significance.
NOTICE
Only ever operate the steam sterilizer with a sterile filter inserted.
Decontaminating textiles
WARNING
The incorrect decontamination of textiles, e.g. a textile package can prevent steam
penetration and/or produce poor drying results. The textiles could not be sterilized.
This could endanger the health of patient and practice team.
Please comply with the following points when treating textiles and putting the textiles in sterilization
containers:
uComply with both the manufacturer's instructions of the textiles regarding treatment and sterilization as
well as the relevant standards and directives e.g. from the RKI and DGSV.
uArrange the folds in the textiles parallel to each other.
uStack textiles vertically wherever possible and not too closely together in the sterilization container.
This enables the development of flow channels.
uRetain the vertical stacking system when packing textiles in the sterilization container.
uIf textile packages do not remain together, wrap the textiles in sterilization paper.

7 Sterilization
19
uOnly ever sterilize dry textiles.
uThe textiles may not be permitted to come into direct contact with the sterilization chamber; otherwise
they will become saturated with condensate.
Decontaminating the instruments
WARNING
The incorrect decontamination of instruments could result in any dirt residue being
loosened by the steam pressure during sterilization.
The use of unsuitable care agents e.g. water repellent agents or oils impermeable to
steam could result in unsterile instruments. This represents a danger to the health of
both patients and yourself.
NOTICE
The presence of residual disinfection and cleaning fluids results in corrosion.
This could result in increased maintenance requirements and a restriction of the steam
sterilizer function.
Please ensure the following when treating used and brand-new instruments:
uFollow both the instrument manufacturer’s instructions regarding decontamination and sterilization and
comply with the relevant standards and directives e.g. from the BGV A1, RKI and DGSV.
uClean the instruments exceptionally thoroughly e.g. using an ultrasonic device or washer-disinfector.
uRinse the instruments after washing and disinfecting, where possible with de-mineralized or distilled
water and then dry the instruments thoroughly with a clean, non-fuzzing cloth.
uUse only those care agents suitable for steam sterilization. Consult the manufacturer of the care
agents. Do not use any water repellent agents or oils impermeable to steam.
uWhen using ultrasound devices, care equipment for handpieces and washer-disinfectors, please
comply with the manufacturer’s treatment instructions.
Frequency of sterilization
Pause times between the individual programs are not necessary, as the sterilization chamber is
maintained permanently at the same temperature. After the end/abort of the drying time and removal of the
sterilized equipment, you can load the steam sterilizer again and start a new program.
Loading the steam sterilizer
Effective sterilization and good drying is only possible if the steam sterilizer has been loaded correctly.
Ensure the following during loading:
uInsert trays or cassettes in the chamber only with their appropriate mount.
uUse perforated trays such as those from MELAG. Only in this way can condensate drain off. The use
a non-perforated base or half-shell to accommodate the sterilization material can result in poor drying
results.
uThe use of paper tray inserts can also result in poor drying results.
uWherever possible, please ensure the separate sterilization of textiles and instruments in separate
sterilization containers or sterilization packaging. This leads to better drying results.

7 Sterilization
20
Packaging
Only ever use packaging materials and systems (sterile barrier systems) which fulfil the standard
DINENISO11607-1. The correct use of suitable packaging is important in achieving successful
sterilization results. You can use re-usable rigid packaging systems such as e.g. standard tray cassettes or
soft packaging such as transparent sterilization packaging, paper bags, sterilization paper, textiles or
fleece.
Closed sterilization containers
CAUTION
The use of unsuitable sterilization containers results in insufficient steam penetration
and even failure of the sterilization. This can also prevent condensate drain-off.
This produces poor drying results. This can result in unsterile instruments and thus
endanger the health of patient and practice team.
CAUTION
Incorrect stacking of the sterilization containers can result in the dripping condensate
being unable to drain off to the chamber floor. This can saturate sterilization material
directly underneath it.
This produces poor drying results. This can result in unsterile instruments and thus
endanger the health of patient and practice team.
nDo not cover the perforations when stacking the sterilization containers.
Please comply with the following when using closed sterilization containers for sterilization material:
uUse aluminium sterilization containers. Aluminium retains and conducts heat and thus accelerates
drying.
uClosed sterilization containers must be either perforated or have a valve on at least one side -
optimally the bottom. MELAG sterilization containers fulfil the requirements for successful sterilization
and drying.
uThe perforations of one-sided perforated sterilization containers should be at the top of any containers
such as with MELAstore-Boxes.
uWherever possible, please ensure that sterilization containers are only stacked on top of those of
identical size, so that the condensate can run down their sides.
uEnsure that the perforations are not covered when stacking the containers.
Tip: MELAG sterilization containers fulfil the requirements of DIN EN 868-8 for successful sterilization and
drying. They have a perforated lid and base and are fitted with disposable paper filters.
Soft sterilization packaging
Soft sterilization packaging can be used in both sterilization containers and on trays. Please comply with
the following when using soft sterilization packaging e.g. MELAfol:
uArrange soft sterilization packaging in a perpendicular position and at narrow intervals.
uDo not place multiple soft sterilization packages flat on top of each other on a tray or in a container.
uIf the seam seal tears during sterilization, this could be caused by the choice of undersized packaging.
Should this not be the case, re-pack the instruments and sterilize them again.
uShould the seam seal rip during sterilization, extend the sealing pulse on the film sealing device or
make a double seam.
Multiple wrapping
The steam sterilizer works with a fractionated pre-vacuum procedure. This permits the use of multiple
packaging.
