Intended use
The MELAtherm 10 Evolution DTA/MELAtherm 10 Evolution DTB is intended for use in a medical context such as a clin-
ic or medical and dental practices. }ENISO15883-1 and -2 defines it as a washer-disinfector intended for }reprocessing
medical instruments prior to their re-use or a further reprocessing step such as sterilization in a steam sterilizer. You can
subject thermostable medical instruments (i.e. instruments which are heat resistant to a temperature of 95°C) and inva-
sive thermostable instruments to automatic reprocessing as long as they are suitable for this purpose and have been
approved for such treatment by their manufacturer. The cleaning is performed using water in combination with
a }process agent (e.g. MEtherm). Subsequent disinfection is thermal disinfection. This device is not intended to be used
in a patient environment.
This device is NOT suitable for the reprocessing of:
nThermo-unstable instruments e.g. flexible endoscopes
nLaboratory waste requiring disposal
nCrockery
nBedpans
User benefits
Universal use
The device both cleans and disinfects. The disinfection phase is conceived so as to reach an }A0 value of at least 3000.
This kills vegetative bacteria, fungi and their spores and viruses (incl. HBV, HCV). This means that the }effectiveness
range AB is reached in accordance with the specifications of the Robert Koch Institute.
Active drying
The device is equipped with active drying. An integrated drying fan dries the instruments from outside and in after clean-
ing and disinfection. The HEPA filter guarantees drying with contamination and particle-free air. This protects the instru-
ments against corrosion. Manual subsequent drying is usually not necessary. The geometry of some hollow-body instru-
ments mean that they require additional drying.
Automatic sieve recognition
The device recognises automatically before a program start whether the fine sieve has been inserted in the base of the
washing chamber. The fine sieve avoids a situation in which instrument components enter the opening of the drain pump
or the circulating pump during cleaning, thereby compromising the function of the pumps, rinse arms and the injector rail.
Internal water softening
The device is equipped with an internal water softening unit. The water hardness of the local drinking water is set on the
device. The internal water softening unit then automatically adjusts itself to the most suitable performance. This ensures
best reprocessing results.
Monitoring the rotation speed of the rinse arms
The rotation speed of the rinse arms is subject to permanent monitoring during a program run. This ensures that the
cleaning process proceeds without hindrance and the rinse arms do not become blocked e.g. by protruding instruments
in the washing chamber.
Monitoring the rinsing pressure
The rinse pressure is monitored by a pressure sensor during a program run. This ensures an effective cleaning perfor-
mance. The device aborts a current program if too much foam is generated.
Metering monitoring
The required amounts of cleaning agent and neutraliser are metered using a metering pump. A measuring turbine per-
forms flow monitoring. The rinse aid is metered using a metering pump subject to monitoring for rotation speed.

3 Performance specifications

Drawer for process agents
The drawer for the }process agents is located in the lower area of the device in which the cleaning agent, neutraliser and
rinse aid containers are stored.
Automatic conductivity measurement
If the device is supplied with }DI water in the final rinse, the DI water fed in is subject to automatic internal conductivity
measurement.
Program sequence
The following program steps are indicated on the display during the program run. The program runs will be significantly
defined through the process-relevant parameters (VRP) specified in the technical manual.
Pre-cleaning
The water-soluble soiling will be rinsed roughly with cold water and removed from the device. This prevents protein fixing
from too high a water temperature; the soiling load of the rinse liquor in the following program steps will be reduced con-
siderably. In Intensive-Program, this step is performed twice.
Cleaning
Water is fed into the washing chamber and heated. When the metering temperature has been reached, a mildly-alkaline
or alkaline }cleaning agent will be metered. Once the cleaning temperature has been reached, the holding time begins,
which ensures a reproducible cleaning effectiveness.
Neutralisation
The cleaned instruments will be freed from alkali residue during neutralisation. At the same time, this prevents the devel-
opment of acid-soluble deposits such as limescale and foreign corrosion. To this end, water will be fed into the washing
chamber, a citric acid or phosphoric acid-based }neutraliser will be metered and short circulation will be performed.
Intermediate rinsing
Water is fed into the washing chamber and circulated cold. This rinses off the neutraliser residue. In Ophthalmo-Pro-
gram, this step is performed twice.
Disinfection
The disinfection is the same as the final rinse. The cleaned and rinsed instruments are subject to thermal disinfection.
Water, preferably }DI water is fed into the washing chamber and heated. When the metering temperature is reached,
a }rinse aid is metered in the Quick-Program, Universal-Program and Intensive-Program. Once the disinfection tempera-
ture has been reached, the holding time begins, which ensures a reproducible disinfectant effect.
Drying
Active drying is effected by drawing ambient air through a class H13 }HEPA filter and heating it. The instruments are
dried inside and out with hot, filtered air.
Displaying the batch counter
The display shows the batch number of the last program run and the total batch counter after every program end or the
end of a program abort.

Process agents
Note the following:
nUse only suitable }process agents. The use of unsuitable process agents can impair the reprocessing result and
material compatibility.
nMELAG recommends using MEtherm process agents. The suitability of the MEtherm process agents for use in
MELAtherm has been proven in comprehensive cleaning effectiveness and material-compatibility tests.
nOther process agents must not be used if their performance and safety for use with the MELAtherm have not been
conformed by the manufacturer of the process agents.
nPlease address all queries relating to the compatibility of process agents with the instruments to the instrument
manufacturer.
nEvery change of a process agent in a validated device necessitates revalidation. Comply with all national
regulations.
Pre-set metering concentration
The pre-set metering concentrations have been harmonised to MEtherm.
Program }Cleaning agent }Neutraliser }Rinse aid
Universal-Program 6 ml/l 1.5 ml/l 0.3 ml/l
Quick-Program 6 ml/l 1.5 ml/l 0.3 ml/l
Intensive-Program 10 ml/l 1.5 ml/l 0.3 ml/l
Ophthalmo-Program 6 ml/l 1.5 ml/l --------
NOTICE
When using process agents from other manufacturers, it may be necessary to adjust the metering
concentration. Only trained and authorised service technicians are permitted to change the metering
concentration.

Setup and installation
PLEASE NOTE
Comply with the specifications of the technical manual during setup and installation. This contains all
building-side requirements.
Record of installation and setup
The record of installation and setup is to be completed by the responsible stockist and a copy sent to MELAG as proof of
the correct setup, installation and initial commissioning. This is a constituent part of any guarantee claim.
Water supply
The }reprocessing of medical devices requires the use of potable water in accordance with the Drinking Water Ordi-
nance.
The potable water supply is effected on the input side via the house supply.
The quality of the water used for reprocessing influences the value-retention of the }load. Silicate or chloride cannot be
removed by the internal water softening unit and will result in the development of stains and corrosion. Working in con-
sultation with specialist associations (e.g. in Germany }AKI, }DGSV, }DGKH) MELAG recommends performing a final
rinse with demineralised water (DI water).
PLEASE NOTE
The final rinse and the partial cycle Disinfection are the same in MELAtherm.
During installation, it is determined whether DI water is to be used in the final rinse (partial cycle Disinfection). In addition,
depending on customer-specific requirements, the service technician can parametrise the partial cycles pre-cleaning,
cleaning, neutralising and intermediate rinsing to DI water. The DI water supply is effected via a water treatment unit (e.g.
MELAdem53/53 C).
Increased requirements can be placed on the quality of the }DI water (e.g. a low endotoxin content) for
the }reprocessing of certain medical devices such as ophthalmic instruments.
Note the following:
nIn such cases, an additional filter system is required for the reprocessing of DI water. Comply with the specifications
of the user documentation of your water treatment unit.
nIt is possible that the drinking water has been contaminated by the water installation. This includes both the domestic
installation and the entire upstream peripherals.
nArrange for a check of the drinking water quality at the removal point or request a report (e.g. from the building
management) before setting up and installing the device.
nFurther information is available from the corresponding trade associations and their publications. If in doubt, contact
your stockist or the pertinent professional association.
