outage F512. Warning!

Load NOT disinfected!

Possible cause

1.

The basis basket has

been inserted incor-

rectly or not at all.

2.

Strong foam genera-

tion: The instruments

are pre-cleaned in a

foam-generating solu-

tion or are dropped in

and subject to insuffi-

cient rinsing.

3.

Non-cleared process

agents (rinse aid or

cleaning agent) were

used / the metering

concentration has been

set incorrectly.

4.

Large receptacles are

to be placed in the bas-

ket with the opening fa-

cing upwards. Other-

wise, they take the wa-

ter from the rinse li-

quor.

5.

The blind cap on the in-

jector rail could have

leaks.

The salt storage has been

exhausted. No new

regeneration can be

performed.

Liquid in the floor trough.

A running program was

interrupted by a power

outage.

Remedy

1.

Check whether the basis basket

has been fitted correctly. The in-

jector rail should be located on the

right-hand side and dock with the

blind cap on the port of the rear

wall (see

Inserting the basis bas-

ket

[} page 24]).

2.

Re-start the program again. If a

malfunction message is displayed,

open the door.

– Check for foam in the washing

chamber.

– PLEASE NOTE: do not pre-

treat the instruments. Remove

any strongly encrusted soiling

manually.

3.

Check whether the connected pro-

cess agents have been approved

by MELAG.

Check the settings of the metering

concentration and if necessary, ar-

range for the technical service to

correct them.

4.

Setup the containers with their

opening facing downwards.

5.

Check the black plastic seal on

the fore-side of the injector rail for

its stability.

Re-fill the regenerating salt.

A program can then be started if the

salt has dissolved in the water. Do not

start the program until the

regenerating salt has been filled and

the signal tone has sounded.

▪ Switch off the device and close the

water inflow tap. Check whether ex-

ternal influence has enabled water

to enter the device. CAUTION!

Avoid contact with liquids in the

device floor trough; they can include

process agents.

▪ Contact your technical service pro-

vider and name the device serial

number and the malfunction number

displayed.

Acknowledge with the «4» key. The

program must be restarted as the

disinfection is not guaranteed.

Do not switch off the device at the

power switch whilst a program is

running.

User Benefits
Universal use
The device cleans and disinfects. The disinfection phase is conceived so as to reach an A0-value of at
least 3000. This eliminates vegetative bacteria and fungi/fungal spores and disables viruses (inc. HBV,
HCV) thus reaching the effective range AB in according to the (German) RKI directive.
Active drying
The device has an active drying facility. This means that after cleaning and disinfection, the instruments
are dried inside (interior lumen) and out via an integrated drying fan. The HEPA-Filter guarantees drying
with contamination-free air. Automatic treatment of hollow-bodied instruments is also possible. This
protects the instruments from stain accretion and rusting. The geometry of some hollow-bodied
instruments such as turbines, requires additional drying.
Automatic sieve recognition
The device recognizes automatically before a program start whether the fine sieve has been inserted in
the base of the washing chamber. Thus it avoids a situation in which instrument components enter the
opening of the drain pump or the circulation pump and thus compromising the function of the pumps, rinse
arms and the injector rail.
Internal water softening
The device has an internal softening plant. The water hardness of the local drinking water is set in the
device. The internal water softening unit then automatically adjusts itself to the best solution. This ensures
a optimal instrument decontamination result.
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 properly and the rinse arms do not become blocked e.g. by
protruding instruments in the washing chamber.
Monitoring the cleaning pressure
The cleaning pressure is monitored during a program run via a pressure sensor. This ensures effective
cleaning. Excess foam generation results in the interruption of the program run.
Metering monitoring
The required amounts of cleaner and neutralizer are measured out using a hose measuring pump. A
measurement turbine performs flow monitoring. The rinse aid is metered using a hose metering pump
subject to monitoring for rotation speed.
Drawer for process agents
The drawer in the lower area of the device provides storage space for the process agents cleaning agent,
neutralizer and rinse aid.
Automatic conductivity measurement
If the device is provided with DI water in the final rinse, the DI water is subject to automatic, internal
conductivity measurement.
Emergency opening of the door
The door can be opened manually via the emergency release following a power outage or malfunction.





4 Performance specifications

Program sequence
The program steps are indicated on the display during the program run:
Pre-cleaning
Pre-cleaning is performed with softened water and without process agents. It is temperature controlled. All
proteins on the instruments must be removed entirely. It is necessary to avoid denaturation resulting from
too a high water temperature. These and other coarse organic deposits are removed during pre-cleaning.
Cleaning
The actual cleaning is performed during the cleaning process. The washing chamber is heated until
reaching the program-specific temperature. This is then held during the holding time. The cleaner is added
automatically before the holding time begins.
Neutralization
The main cleaning is followed immediately by neutralization. Neutralization reduces alkalinity and frees the
instruments from acid-soluble deposits such as lime scale and extraneous rust etc. During this process, a
specified amount of cold process water is pumped into the washing chamber. This is followed by the
addition / mixing of a measured amount of neutralizer.
Intermediate rinsing
Intermediate rinsing is a preparatory step to disinfection to reduce the residual concentration of the
process agents.
Disinfection
Intermediate rinsing is followed by thermal disinfection at a temperature of over 90°C.
Drying
The instruments are then dried by the integrated drying fan from inside and out. 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
Observe the operating and safety information from the process agent manufacturer.
Process agents from different manufacturers may not be mixed. Any change to another
authorized combination may only be performed by trained service partners. 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.
The following combinations of process agents were tested for suitability for use with MELAtherm 10,

u Flush all hollow-bodied instrument after use with patients / before automatic treatment.
u Treat only those hollow-bodied instruments which guarantee sufficient and reproducible rinsing. Re-
move instruments with a recognisably reduced throughflow.
u Use only MELAG adapters (accessories list) for the injector rail to treat hollow-bodied instruments. The
suitability of the hollow-bodied instruments for the respective adapter and the sufficient flushing of the
instruments can only be proven by validation.
u Check the connections between the adapter and the hollow-bodied instrument for stability both before
and after treatment. Should a connection work loose after treatment, the instruments must be treated
again.
u Comply with the cleaning and replacement intervals when using filter inserts. The cleaning and re-
placement intervals are listed in the separate document Instructions for the use and care of the ac-
cessories.
u When treating dental and ophthalmologic transfer instrument, observe and comply with the special

purpose.
n Do not treat any instruments which are used for operations of the posterior segment surgery
(contact with retinal tissue, sub-retinal fluid and the optical nerve).
n These devices should be fitted with a suitable filter system: Ophthalmological instruments
may only be treated using the filter discs (MELAG art. no. 64375).
NOTICE
Use only those instruments designed by their manufacturer for automatic treatment in a
washer-disinfector.
n Some brands are only authorized for thermal disinfection after a specific year of manufac-
ture.
n Comply with the information from the relevant instrument manufacturer.
NOTICE
Do not use a rinse aid to treat ophthalmological instruments.
n Remove the container for the rinse aid from the process agents drawer and hang the black
suction lance in the suction lance bracket.
PLEASE NOTICE
Use demineralized water to treat ophthalmological instruments.
n To this end, connect a mixed-bed resin cartridge.

Suitable program
Treat ophthalmological instruments in the Ophthalmo-Program. Only this program enables monitoring of
the conductivity during the disinfection phase; this ensures an uncritical residual conductivity.
Comply with the following specifications before automatic treatment:
u Cleaning should be undertaken with a mildly alkali cleaner. Neutralization should be effected with a cit-
ric acid based neutralizer.
u Flush all hollow-bodied instruments with DI water following patient use / before automatic treatment
u Treat only those hollow-bodied instruments which guarantee sufficient and reproducible rinsing. Re-
move instruments with a recognisably reduced throughflow.
u All hollow-bodied instruments should be connected with the rinse bar designed for the purpose.
u Ensure that plugs and / or cables from phaco handpieces are not able to slip through the basis basket,
otherwise the rinse arm can become blocked.
u Try to prevent dirt from drying or encrusting on and in the instruments.
u Dry the hollow-bodied instrumts with clean (medical) compressed air after treatment in order to re-
move any residual moisture.
u When using the rinsing system, individual outlets which are not connected can be sealed with suitable
accessories.
Instrument care
Comply with the manufacturer's instructions regarding the care and maintenance of the instruments / the
load accessories.
Routine controls
Perform a routine check of the pH value after treatment of the hollow-bodied instruments.
1. Blow through the hollow-bodied instruments with medical compressed air onto indicator paper (e.g.
From Macherey-Nagel: PEHANON pH 4.0-9.0). The ph-value should be 0.5 or even more exact.
2. Compare the value displayed on the indicator paper with the pH value of the final rinse water from the
previous performance qualification.
3. Should you discover any deviations, contact the customer services.
Overview of programs
u Choose the program according to the level of soiling of the load. Comply with the specifications from
the validation.
u The Universal-Program is sufficient for every-day general cleaning and disinfection. The Quick-Pro-
gram is designed for lightly-soiled instruments.

Batch documentation
The batch documentation acts as proof of the successful conclusion of the sterilization process and
represents an obligatory part of quality control. The data, such as type of program as well as batch and
process parameters of the completed programs, are stored in an internal log memory of the device.
To obtain the batch documentation, you can read out the internal log memory and transfer its data to
various output media. This can be performed immediately at the end of every program or at a later point,
such as at the end of the day.
As delivered, the MELAflash CF card is set as the output medium. Setting a different output medium or
activating the internal log memory is outlined under Settings [}page 18].
Capacity of the internal log memory
The device is equipped with an internal log memory. This saves all the data regarding the sterilization
program automatically. The capacity of the internal log memory is sufficient for 15-20 logs. If the internal
log memory is full, the display will show the warning Internal program log memory full, do not
output all logs. If this warning is issued, provide the specified output medium (see Settings [}page
18] menu → Logging) and output the affected log (→ Logging [}page 18] menu). If the program is
continued, the logs are deleted automatically; the last ten saved logs remain in the log memory.
We recommend outputting logs immediately.
Outputting logs immediately and automatically
u The text log is issued on the selected output medium after the end of the program run. At the same
time, this text log is saved in the internal log memory and marked as “outputted”.
u If multiple output media have been activated, all activated output media must be connected to the
device. Otherwise, the text logs are saved in the internal memory and are classed as “not outputted”.
u If the internal log memory is full, the device will register all the text logs which are classed as “not out-
putted”. The warning 386 appears after the program start. You can acknowledge this warning with the
 key in order to continue the program run.
u With warning 372, logs not yet outputted must be outputted manually. Only then is a program start
possible. The log memory is deleted automatically after manual issue; the last ten logs remain in the
log memory. The manual outputting of logs is outlines under Subsequent log output [}page 41].
Output media
You can output the logs of the finished programs via the following output media:
▪ MELAflash CF card
▪ A computer via the practice network (LAN)
▪ MELAprint 42 log printer with network adaptor
The output media can be combined in any fashion. Thus it is possible both to save logs on the CF card
(included in the scope of delivery) and also to print them on the log printer.
PLEASE NOTICE
Further information about the log printer (e.g. the duration of the readability of the log
print-out) is specified in the appendant operating manual.

Finding the logs
PLEASE NOTICE
Do not rename the directory, otherwise logs will be stored in both the renamed directory
as well as the new device directory generated automatically by the device.
All storage media (CF card or computer) contain a directory with the encoded serial number of the device
concerned following log output. The folder name consists of five characters identical with the first five
characters of every log, e.g. CR0ZH. This directory contains a sub-directory with the month of log
generation e.g. 01_2013 for January 2013. This contains all logs generated by the device this month. The
device directory is entered in the main directory on the CF card.
The device checks the storage medium after every type of log output (immediate output after a completed
cycle or the transfer of multiple logs simultaneously). Should a directory not exist, it creates one of device
and a month. If logs are issued on the same storage medium more than once, a “duplicated" directory will
be created under the device directory in which these logs will be saved only once.
Given direct log transfer to a computer, set the storage location in the program (FCP, FTP) used on your
computer.

u Check the material compatibility before application!
u Never use solvents or benzene.
u Use surface disinfectants which are suitable for plastics. Observe the manufacturer's information on
the respective surface disinfectant.
Pump pit and non-return valve
If the rinse water has not been removed entirely after a program, the non-return valve must be cleaned.
1. Remove the coarse and fine sieves and remove the
residue and deposits from the pump pit.
2. Remove the non-return valve upwards by pulling on
its grip and pull it out of the pump pit.
3. Clean the non-return valve under running water. Do
not use any dishwashing detergent.
4. Replace the non-return valve and the fine and
coarse sieve in the pump pit.
5. Start the “Rinse” program.
Avoiding staining
Stains on the instruments or the device can develop from poor water quality. In particular, heavy metals or
chloride deposits can result in the development of stains and rust. To avoid the development of stains on
the instruments or the washing chamber, we recommend a final rinse with deionised water (DI water). All
water-conducting parts of the device are made of non-rusting materials. This excludes the formation of
stains or rust caused by the device. Often a rust-producing instrument already suffices for third-party rust
to form on the other instruments or in the device. Further information is provided in the document How to
optimise cleaning and protect instruments.
Changing the filter in the drying fan
Exceeding the permissible level of blockage can result in a worsened drying outcome. For this reason, the
device checks the degree of blockage automatically. Exceeding the tolerances results in the issue of the
relevant display message.
DANGER
Careless touching of the HEPA filter may damage the lamellae.
This may impair filter services and recontamination of the disinfected instruments.
n Only touch the HEPA filter by the frame and do not damage the lamellae.





11 Maintenance

PLEASE NOTICE
The pre-filter and HEPA filter must be changed yearly (e.g. during maintenance).
1. Pull the process agent drawer forwards.
2. Undo the screw on the cover cap of the drying fan by
hand and lift up the cover cap.
3. Pull out the pre-filter upwards and replace it.
4. Take out the HEPA filter upwards and replace it.
5. Close the cover cap and turn the screw hand-tight.

and replaced where necessary. Maintenance is carried out according to the maintenance instructions
relevant for this device.





11 Maintenance
50
Maintenance is to be performed after every 1000 cycles or after 18 months at the latest. Please note any
restrictions arising from the process agents used (see Approved process agents [}page 11]).
(Process) validation
A reproducible cleaning and disinfection outcome can only be ensured via correct operation (inc. use of
suitable accessories). The practice operator is responsible for ensuring reproducibility through the use of
batch, routine and / or periodic inspections (e.g. validation). 
This requirement is made (in Germany) by e.g. the Medizinprodukte-Betreiberverordnung (§ 4 Abs. 2
MPBetreibV); DGKH, DGSV and AKI directives and the recommendations from the Robert-Koch-Institut.
This requirement is also made in international regulations. This is based on DIN EN ISO 15883, which is
also valid in Germany. 
Please observe all valid national regulations and specifications. In case of doubt, please consult the
relevant professional association.
▪ Only use the loading pattern specified and approved within the scope of the validation.
▪ We cannot provide a guarantee for non-MELAG accessories, even if they are in possession of valida-
tion.

Glossary

Glossary
A0-value
The A0 value represents a standard for the elimin-
ation of microorganisms and the deactivation of vir-
uses in the disinfection procedure with damp heat.
The A0 value depends on temperature and time.
Authorized personnel
An authorized  personnel can be  a medical  stock-
ists, depot  technicians or  MELAG-authorized cus-
tomer services trained by MELAG.
Batch
Collection of  sterilization  material which has  been
processed  together  in  the  same  sterilization  pro-
gram.
Cleaner
The cleaning agent serves the removal of organic
material  (e.g.  blood).  The  maximum  pH  value  of
the  working  solution  of  a  mildly-alkaline  cleaning
agent is 11.
DI water
Demineralized  water,  also  known  as  de-ionized
water  or  deionate.  Water  (H2O)  which  does  not
contain  the  minerals  (salts,  ions)  found  in  source
and tap water.
Empty batch
Program  run  without  a  load  or  accessories  (only
with a basis basket).
Neutralizer
In  addition  to neutralizing  the  cleaning  agent,  the
neutralizer  serves  to  protect  the  instruments  and
brightens their stainless steel surface.
pH value
The pH value is a measure of  the  strength  of the
acid or alkali effect of a watery solution.
Rinse aid
The rinse aid serves the subsequent rinsing of the
instruments before drying.  The rinse aid dries  the
load faster and without stain accretion.
VDE
German abbreviation "Verband der Elektrotechnik,
Elektronik  und  Informationstechnik  e.V."  (Alliance
of  the  Electronics,  Electrotechnical  and  IT  In-
dustry).
