Detailed information regarding the various mounts, their combinability with various load holders and their application can be found in the document “Usage instructions for mounts”. Mount A “Plus”...
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.
5 First steps Wastewater connection The wastewater can either be collected in the internal storage tank on the wastewater side (left) and be removed manually or be let out automatically via the one-way outlet. An upgrade kit can be ordered to connect the steam sterilizer to the wastewater.

6 Loading the steam sterilizer 6 Loading the steam sterilizer 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.
Page 22
Insert trays or cassettes in the chamber only with their appropriate mount. Use perforated trays such as those from MELAG. Only in this way can condensate drain off. The use of a non-perforated base or half-shell to accommodate the sterilization material can result in poor drying results.
Page 23
Ensure 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.
(see above). The use of another test system in accordance with DIN EN 867-5 is possible. The number of the available test systems means that MELAG is not able to provide technical support when using a different system. The indicator test strips used need not be stored.
7 Sterilization Selecting the program You can switch between the initial state and the desired program using the program selection key 'P'. Now select the sterilization program according to how and whether the sterilization material is wrapped. It is also necessary to take into account the temperature resistance of the sterilization material. The following table shows which program is to be selected for which sterilization material.
PLEASE NOTE The steam sterilizer must remain continually activated for the automatic preheating. MELAG recommends activating the automatic preheating function. To alter this setting proceed as follows: Select Function by pressing the '+' and '-' keys simultaneously until the display shows Function: Last batch number.
NOTICE Unsupervised operation of electrical devices, including this steam sterilizer at the operator’s risk. MELAG accepts no liability what so ever for any damage resulting from unsupervised operation. After having selected a program via the program selection key 'P', the display will show both the selected program and sterilization temperature as well as whether the program is suitable for wrapped or un- wrapped sterilization material.
7 Sterilization The steam sterilizer provides excellent drying of the sterilization material. If difficult-to-dry items require better drying, you can undertake the following steps to improve drying: Load the steam sterilizer properly. Stand e.g. the transparent and paper sterilization packaging upright.
Page 29
7 Sterilization Proceed as follows to abort the program during drying: Press the 'S' key. Confirm the following security query Stop program? by pressing the 'S' key repeatedly. PLEASE NOTE The security query will be displayed for approx. five seconds. If the 'S' key is not pressed again, the program will continue with the usual program run.
7 Sterilization Removing the sterilized equipment CAUTION Danger of burns from hot metal surfaces Allow the device to cool sufficiently before opening. Do not touch any hot metal parts. CAUTION Unsterile instruments resulting from damaged or burst packaging. This endangers the health of your patients and practice team.
8 Logging 8 Logging Batch documentation The batch documentation serves as proof of the successful conclusion of the program and represents an obligatory part of quality assurance (MPBetreibV). The device internal log memory saves such data as the program type, batch and process parameters of all the programs completed. To obtain the batch documentation, you can output the internal log memory and transfer its data to various output media.
8 Logging Output media You are able to output and archive the logs of the completed programs on the following output media: ▪ MELAflash CF card printer on the CF card ▪ Computer, e.g. with MELAtrace/MELAview software (optionally with MELAnet Box) ▪...
Page 33
8 Logging Reading out text logs on the computer You can use the MELAtrace/MELAview software to read out the logs. The following settings are required to register the computer on the steam sterilizer: Switch on the steam sterilizer. Wait until the display shows the initial state. Select SETUP menu Function by pressing the '+' and '-' keys simultaneously.
8 Logging Mark the editor and confirm with “OK”. Ê You can then open files with this ending via a double-click in Windows Editor. Alternatively, you can open all text logs with the documentation software MELAtrace/MELAview (from MELAview 3). Outputting logs immediately and automatically Text logs If you want to output the associated text log on an output medium automatically and immediately after the end of a program, use the following function: Immediate output YES.
PLEASE NOTE If immediate output is unable to output a log, for example, because the output medium activated is not connected, a warning will appear. MELAG recommends using the immediate log output function. For log output immediately after program end, comply with the following: In SETUP menu Function: Log output MELAnet+graphic data must be selected as the output...

10 Maintenance Internal storage tank Should you use the internal storage tank for the feed water supply, perform regular checks and cleaning as follows: Interval Upon every refill Check the storage tank for soiling. If necessary, use a cloth and fresh feed water to clean the storage tank before filling.
10 Maintenance Avoiding staining Only proper cleaning of the instruments prior to sterilization enables you to avoid residue from being released from the load under steam pressure during sterilization. Loosened dirt residue can clog the filter, nozzles and valves of the steam sterilizer and deposit themselves on the instruments and chamber as deposits and stains.
10 Maintenance Insert the door seal in the groove of the round blank. PLEASE NOTE Make sure that the broad seal face faces the chamber. The door can only be shut correctly and the chamber sealed, if the door seal sits correctly in the groove. Replacing or sterilizing the sterile filter The sterile filter must be replaced regularly within the scope of the maintenance.
Page 46
10 Maintenance Replace the sterile filter or sterilize the current sterile filter, see Sterilizing the sterile filter [} page 46]. Exert a little pressure on the sterile filter and turn to insert it into the holding sockets. Sterilizing the sterile filter Remove the sterile filter by turning and pulling it from the holding sockets simultaneously.
10 Maintenance Cleaning the filter in the chamber Screw out the condensate return filter (pos. a) and the chamber filter (pos. b) anti-clockwise from the opening in order to perform a check. Unscrew the chamber filter (pos. b) using the chamber filter wrench included in the scope of delivery (pos. c). Rinse the filter (a and b) for cleaning with water.
