Intended use
The MELAtherm10 Evolution DTA/DTB is intended for use in a medical context such as a clinic 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 invasive 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 clean-
ing 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:
uThermo-unstable instruments e.g. flexible endoscopes
uLaboratory waste requiring disposal
uCrockery
uBedpans
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 (inc. HBV, HCV) so that the
effective 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 inside and
out after cleaning and disinfection. The additionally fitted HEPA filter guarantees drying with contamina-
tion-free air. The automatic reprocessing of hollow-body instruments is also possible. This protects the
instruments from stain accretion and rusting. The geometry of some hollow-body instruments mean that
they require additional drying.
Automatic filter recognition
The device recognizes 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 circulation 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 wa-
ter is set on the device. The internal water softening unit then automatically adjusts itself to the most suit-
able performance. This ensures best reprocessing results.
Monitoring the speed of the rinse arms
The rotation speed of the rinse arms is subject to permanent monitoring during a program run. This en-
sures 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 the program run. This ensures an effective
cleaning performance. The device aborts a current program if too much foam is generated.

3 Performance specifications
9
Metering monitoring
The required amounts of cleaning agent and neutralizer are measured out using a hose metering pump. A
measurement turbine performs flow monitoring. The rinse aid is metered using a hose pump subject to
monitoring for rotation speed.
Drawer for process agents
The drawer for the process agents is located in the lower area of the device in which the cleaning agent,
neutralizer and rinse aid containers are stored.
Automatic conductivity measurement
If the device is supplied with DI water in the final rinse, the DI water is subject to automatic internal con-
ductivity measurement.
Manual door emergency-opening
The door can be opened manually in an emergency via the emergency opening following a power outage
or malfunction.
Program sequence
The following program steps are indicated on the display during the program run.
Pre-cleaning
Pre-cleaning is performed with cold (min. 22 °C), softened or de-ionized water without process agents.
Instrument soiling and contamination (proteins and/or coarse organic deposits) are subject to mechanical
cleaning to avoid denaturation from excessively-high water temperatures.
Cleaning
The pre-cleaning is followed by the actual cleaning phase with warm process water and the addition of a
mildly-alkaline cleaning agent. As part of the cleaning process, a defined volume of process water is let
into the washing chamber and heated to 40 °C. The mildly-alkaline cleaning agent is automatically
metered to the process water as soon as the set temperature has been reached.
The process water is heated to 55°C for the actual cleaning process. This temperature is maintained and
any remaining organic deposits will be removed from the instruments.
Neutralization
Main cleaning is followed immediately by neutralization. Neutralization reduces the alkalinity introduced
during cleaning and removes acid-soluble deposits such as limescale and extraneous rust etc.
A metered amount of neutralizer is added during this phase. The neutralized process water is subject to
continual circulation for a defined period. Finally, the process water is pumped out of the washing chamber
completely.
Intermediate rinsing
Intermediate rinsing is the preparatory step for thermal disinfection in which the instruments are rinsed
without process agents. The rinsing serves to reduce the residual process agents to a defensible level. In
this phase, a metered amount of cold process water is let into the washing chamber and subject to contin-
ual circulation for a defined period. Finally, the process water is pumped out of the washing chamber.
Disinfection
The disinfection is performed after intermediate rinsing. The disinfectant effect of MELAtherm is achieved
using thermal disinfection and subsequent drying.
A rinse aid is added to the process water at a temperature of 70°C. The thermal disinfection is performed
via continual circulation and heating of the process water to 90 °C and a holding time at this temperature of
minimum 5min. Following the disinfection, the process water is pumped out of the washing chamber com-
pletely.

3 Performance specifications
10
Drying
Drying is effected by drawing ambient air through a class H13 HEPA filter. The instruments are dried
inside and out with hot, filtered air. This prevents the development of rust on the instruments.
Displaying the batch counter
The display shows the batch number of the last program run and the total batch counter after every pro-
gram end or the end of a program abort.
Process agents
NOTICE
Only use process agents of the same manufacturer. Process agents from different
manufacturers may not be mixed. Any change to another combination may only be
performed by trained service technicians. The metering concentration must be adapted
to local conditions. This is to be performed by the service technician during set-up in
accordance with the manufacturer's information.
NOTICE
Observe the operating and safety information from the process agent manufacturer. If,
despite observation of the manufacturer's information, the process agents have a
negative effect on the material of the instruments or the device, liability lies with the
manufacturer of the process agents. The use of process agents not suitable for this
device absolves MELAG of all liability whatsoever for any damage to the device or the
instruments.
MELAG recommends the usage of MEtherm process agents. These are adapted for the process in
MELAtherm and achieve excellent cleaning results with optimal instrument protection. Contact the process
agent manufacturer when using other process agents. MELAG does not accept liability for the cleaning
effectiveness of other process agents in MELAtherm.
Preset metering concentrations
Program Cleaning agent Neutralizer 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 --------
When using drinking water (hardness range medium - hard) we recommend the metering concentrations
as specified. The metering concentration must be adapted individually depending on the local conditions.
The pre-set metering quantities can be used for various combinations of process agents. Observe the
metering specifications of the process agent manufacturer. This information can be read-off from the
canister in the units "ml/l" or on separate data sheets provided by the manufacturer. The process-relevant
parameters must be adapted depending on the nature of the soiling, the quality of the tap water and other
framework conditions.

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 setting up
The record of installation and setting up 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.
Supply with cold water
The reprocessing of medical devices requires the use of drinking water in accordance with the Drinking
Water Ordinance or demineralized water (DI water).
The cold water supply is effected either via the in-house connection of the practice or 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. Comply with the following:
uIn 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.
uIt is possible that the drinking water has been contaminated by the water installation (domestic
installation and pre-device periphery).
uArrange 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.
uFurther information is available from the corresponding trade associations and their publications. In
case of uncertainty, contact your stockist or the pertinent professional association.
Switching the device on and off
}Switch the device on or off at the power switch.
