Disposal
MELAG devices are synonymous with high quality and a long life-span. When you eventually need to
decommission your MELAG device, we offer a special disposal service. Simply contact your stockist.
Dispose of accessories and consumption media which you no longer require in the appropriate manner.
Comply with all relevant disposal specification in terms of possibly contaminated waste.
The packaging protects the device against transport damage. The packaging materials have been
selected for their environmentally-friendly disposability and can be recycled. Returning the packaging to
the material flow reduces the amount of waste and saves raw materials. Dispose of all non-required
packaging materials at the collection points of the dual system.
Dispose of waste from process agents in accordance with the specifications from the manufacturer of the
process agents. Information regarding this topic is provided in the safety data sheets or can be obtained
directly from the manufacturer of the process agents.

Intended use
In accordance with DIN EN ISO 15883-1 and -2, this device is a washer-disinfector intended for use in a
medical context such as clinics and medical and dental practices. You can subject thermostable medical
instruments (i.e. instruments which are heat resistant to a temperature of 95 °C) to automatic reprocessing
as long as they are suitable for this purpose and have been approved for such treatment by their manufac-
turer. The cleaning is undertaken via the use of water and a chemical cleaning agent. Subsequent disin-
fection is thermal disinfection. This device is not intended to be used in a patient environment.
This device is NOT suitable for the decontamination of:
▪ Thermo-unstable instruments e.g. flexible endoscopes
▪ Laboratory waste requiring disposal
▪ Crockery
▪ Bedpans
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 is achieved. 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 outside and
in after cleaning and disinfection. The additionally fitted HEPA filter guarantees drying with contamination-
free air. The automatic decontamination 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
water is set on the device. The internal water softening unit then automatically adjusts itself to the most
suitable performance. This ensures best decontamination results.
Monitoring the speed of the rinse arm
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.

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) will be mechanically
removed 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 temperature is main-
tained (holding time). This is followed by the actual cleaning.
The process water is heated further for the actual cleaning process. Any soiling or organic deposits still on
the instruments are removed at a temperature of 55 °C.
Neutralization
The main wash 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 serve 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 con-
tinual circulation for a defined period. Finally, the process water is pumped out of the washing chamber.
Disinfection
The actual disinfection is performed after intermediate rinsing. The disinfectant effect of MELAtherm 10 is
achieved using thermal disinfection and subsequent drying.
A rinse aid added to the process water at a temperature of 70 °C. The actual thermal disinfection is per-
formed via continual circulation and heating of the process water to 90 °C and a holding time at this tem-
perature of min. five minutes. Following the disinfection, the process water is pumped out of the washing
chamber completely.

Drying
Drying is effected by drawing ambient air through a class H 13 HEPA filter. The instruments are dried
inside and out with hot, filtered air. This prevents rust accretion on the instruments.
Displaying the batch counter
The display shows the last batch number run and the total batch counter after a program end or the end of
a program abort.
Approved process agents
NOTICE
Only use process agents of the same manufacturer. Process agents from different
manufacturers may not be mixed. Any change to another authorized 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
setup 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 approved by MELAG
absolves MELAG of all liability whatsoever for any damage to the device or the
instruments.
