1.4.1 Conformity to european standard____________________________________________________

The autoclaves MELAtronic Steam Sterilizers EN 13060 for autoclaves with sterilization cycle of the type „S“ and „N“ (see section .4.5 and 9.2) . Regarding the sterilization performance the autoclaves MELAtronic the sterilization of unwrapped and solid instruments, for the sterilization of single wrapped solid instruments and also for the sterilization of small amounts of single wrapped textiles. Thermo – electrical Tests according EN 13060 and additional bacteriological tests have approved this perfomance.

1.4.2 Fractionated Gravity system________________________________________________________

With the fractionated gravity system which is used steam flows into and then out of the autoclave to ensure effective penetration of the items to be sterilized by saturated steam. This makes it possible to carry out demanding sterilization tasks rapidly and reliably, such as for example the sterilization of wrapped instruments or textiles.

1.4.3 Operating range for sterilization_____________________________________________________

The autoclaves MELAtronic 134°C: the “Universal Program” (for wrapped objects), the “Prion Program” (a special Universal Program), the “Quick Program” for unwrapped items. The “Gentle Program” is a sterilization program for textiles and rubber articles at 121°C.

1.4.4 Integrated steam generation ________________________________________________________

The powerful steam generation in the sterilization chamber makes it possible to sterilize large loads of instruments or textiles in a short time. This system of steam generation means that excess temperatures in the sterilized chamber are not possible.

1.4.5 One-way / Closed-loop system / Conductivity measurement______________________________

The autoclaves MELAtronic circulatory water system. This means that the water evaporated during each sterilization process is condensed and returned to the water storage tank. This takes place during sub-atmospheric pulsing, and during pressure release. This type of operation is effective for sterilization rates of approx. 2 … 3 sterilization cycles per work day, if sufficiently long pauses between sterilization are observed. In work with a circulatory water system, however, it is very important to ensure that the instruments to be sterilized have been especially carefully cleaned and rinsed before sterilization. In addition, the water should be checked for dirt and debris every day, and the water must be changed at least once a week. If the sterilizer is used often, the water in the water storage tank becomes extremely hot, so that complete condensation in the tank is not possible, and steam will exit from the vent openings (Fig. 1, Pos. 13) on the back wall of the autoclave. Under these conditions, an external condensate tank (MELAG article no. 00356) can be connected to the autoclave, and the condensing coil (Fig. 1, Pos. 18) can be removed from the water storage tank. The autoclave will now operate with a single-use (non-reusable) water system, and the evaporated water for each sterilization will be condensed in the external condensate tank. This configuration has the advantage that the water in the storage tank will not become too hot, and the steam will not be ejected from the autoclave. Another advantage of this installation alternative is that impurities dissolved in the steam will not get into the water of the storage tank – and this means that clean distilled or demineralized water will once again be used for sterilization in the following program cycle. An integrated electrical conductivity sensor monitors the quality of the demineralized or distilled water used to generate the steam. Using the recommended one-way operation for the autoclave, the increased consumption of demineralized or distilled water can be provided by using a water purifier such as the MELAdem

40, MELAdem®47 or the MELAdest®65. Provided that the instruments are prepared carefully for the sterilization, stains on the load and soiling of the autoclave itself can be prevented.

15EN, 17EN and 23-EN operate in the standard installation mode, as a

15 / 17 / 23EN

1.4.6 Electronic Parameter Control EPS ___________________________________________________

The microprocessor used in the MELAtronic

15EN, 17EN and 23EN makes it possible to monitor pressure, temperature and time continuously during a program by Electronic Parameter Control The overall operating time can then be optimised according the load and the temperature of the autoclave. The process assessment and monitoring system in the program control compare current process parameters with standard process data and monitors the process relative to limit values for temperatures, times and pressures. This makes it possible to identify faults as they occur, and provides quality assurance for the sterilization process.

1.4.7 Pre-heating / Drying _______________________________________________________________

By activating the "pre-heating" function, the cold autoclave chamber can be warmed up before sterilization, or the temperature can be maintained between sterilization runs. This reduces the duration of cycles and considerably reduces the formation of condensation, thus improving drying results with slightly opened door.

1.4.8 Documentation ___________________________________________________________________

The memory of the electronic control system stores records of the previous 40 programs. For effective hard-copy documentation and for checking purposes a MELAprint to print out a record immediately after completion of a program, or to print out records from the memory. By connection of a PC, the program MELAwin

can also transfer the records to the PC, for permanent

archiving of all results, and for printing out these results as needed.

2 Installation

2.1 Setting up the autoclave

The autoclave should be set up in a dry place which is protected against dust. The base should be stable, and able to support the weight of the autoclave. At the same time, the work surface must provide convenient access to the autoclave, and the display must be clearly visible. The space required by the autoclave can be seen from the external dimensions (as in Section 1.1). A minimum additional space of 5 cm should be allowed on either side and above the autoclave in order to ensure that heat can escape. If the additional condensate container shall be connected to the autoclave you need an adequate space below the autoclave for the container. The electrical power supply should be a separate 230V AC circuit with a 16 A fuse and optionally protected with a 30 mA circuit breaker. Should it be decided at some stage to install an automatic one-way water system, it is necessary to connect the condensate container as an option. The condensate container must stand below the autoclave and the outlet pipe must be without bends and twists which could prevent water flowing out freely. For the supply with demineralized / distilled water from the integrated water storage tank (Fig. 1 Pos. 26) you need at least a space of 30cm or more above the autoclave.

______________________________________________

2.2 Transport ribbons _____________________________________________________

Take the autoclave out of the packaging by means of the transport ribbons. The blue ribbons themselves are each removed by undoing two retaining screws, which must then be screwed firmly back in place without washers. Therefore you need the TORX-key, delivered with the autoclave

2.3 Levelling_____________________________________________________________

In order to ensure that the autoclave will work reliable, the autoclave should be installed in a horizontal position (this should be checked with a spirit level at the chamber flange) as shown in the pictures below.

Fig. 3 Levelling the autoclave with a spirit level

2.4 Mains power supply

2.5 Filling the water storage tank__________________________________________

Remove the lid of the housing (Fig.1 Pos 27) and the lid of the water tank (Fig.1 Pos. 28) below. Fill the water tank with ca. 3 Litres of aqua dest / aqua dem. Do not fill more water into the tank than up to the "MAX" mark (Fig.1 Pos. 16). The cooling coils in the water storage tank should always be covered with water. This will allow the steam flowing out to condense. It will also prevent and problems from the steam, and will eliminate excessive consumption of distilled or demineralised water. For this reason, be sure to top up with distilled or demineralised water as soon as necessary. Or, better: drain out the remaining water through the water drain tap (Fig. 1, Pos. 6) and refill with fresh distilled or demineralised water up to the MAX mark.

15 / 17 / 23EN

2.6 Connecting the external Condensate container (option)

To operate the autoclave with a single-use (non-reusable) water system (one-way system), and to avoid discharge of steam during frequent sterilization work, an external condensate tank (MELAG article no.

00356) can be connected to the autoclave. This external condensate tank is not part of the equipment provided originally with the autoclave. Please proceed as follows to connect the condensate tank to the autoclave: Remove the blind cap from the connection point for the external condensate tank (Fig. 1, Pos. 11), on the back wall of the autoclave. Connect the drain pipe (supplied with the external condensate tank) to the connection point, and tighten it securely with the coupling ring. Fill up the external condensate tank up to the MIN mark with ordinary tap water, and place the tank under the autoclave. Insert the free end of the drain pipe, as far as it will go, onto the plug-on coupling in the top of the external condensate tank. The drain pipe should not have any kinks or dips, and it should lead continuously downward (without any upward loops). Finally, remove the condensing coil for the pressure release (Fig. 1, Pos. 18) in the water storage tank. Remove this coil by pressing toward the rear the locking ring of the plug-in conne ctor for the condensate loop (Fig. 1, Pos. 19). After removing this coil, store it safely where you can find it easily.

4 Instructions for all sterilization procedures

4.1 Electricity and water supplies

4.1.1 Feed water aqua dest / aqua dem___________________________________________________

The autoclave automatically monitors the availability of cooling water and purified water, as well as the quality of the distilled / demineralized water before starting a program. In order to allow an immediate program start and to avoid error reports or interruptions of programs check before the first sterilization at the start of the working day, that the internal water supply has sufficient water in the water storage tank. If necessary, refill with water of appropriate quality (see Section 8.3.3). Before the first sterilization the quality of the feed water has to be checked by pressing the button „-“ after the autoclave is switched on. Is the conductivity of the water higher than 65 µS/cm, the feed water has to be exchanged and fresh aqua dest / aqua dem has to be filled into the water storage tank.. If the water storage tank is dirty, the water has to be drained and the water storage tank must be cleaned bevor refilling the tank with fresh aqua dest / aqua dem (see also section 8.3.3).

4.2 Preparing instruments for sterilization

MELAG - rust-free materials

All parts of the MELAtronic rusting materials: the pressure chamber and the door of stainless steel, steam pipes of Teflon, and screws and magnet-valves of bronze.

Film rust

The use of these materials means that no parts of the autoclave can initiate rust formation. Where rust does attack the autoclave or instruments sterilized in it, tests repeatedly show that this has been brought into the autoclave on instruments (film rust). Even top-quality stainless steel instruments can form rust if they are not handled properly, e.g. if they are treated with the wrong chemical cleaning or disinfecting agents.

Preparing items for sterilization

The example of the formation of film rust shows how important it is to prepare items properly before sterilization. Handpieces and contra-angles must be cleaned before sterilization and maintained (e.g. by oiling). Other instruments must be disinfected and cleaned immediately after use in accordance with UVV/VBG 103, or similarly strict national codes of practice in a disinfectant and / or cleaning solution at the correct concentration for the correct length of time. MELAG recommends the use of cleaning aids such as ultrasonic baths, cleaning and maintenance equipment for handpieces for contra-angles, as well as thermo-disinfecting devices. It is essential that the instruments are well cleaned in order to avoid dirt and contamination being separated from the load in the autoclave and clogging filters, valves, and nozzles. In particular locks, joints, and hinges must be cleaned thoroughly with a brush before sterilization. No traces of cleaning and disinfecting agent s should be allowed to enter into the sterilization chamber of the autoclave, since this can give rise to corrosion! The instruments should be swilled off with demineralized water and then dried off before bei ng loaded in the autoclave. Turbines and handpieces must be oiled in accordance with the manufacturer's instructions in order to ensure their long working life.

Brand-new instruments

The cleaning procedures described above must also be followed before sterilizing brand-new instruments. These often carry small amounts of grease, oil and soiling from the manufacturing process. Important: Carefully follow all instructions provided by manufacturers of instruments for the preparation of their products for first-time sterilization and for subsequent sterilizations.

4.3 Loading the autoclave

It is of crucial importance for effective sterilization and good drying that the autoclave is loaded properly: In the annex you will get information how to load the autoclave. When loading the autoclave, take account of the following points:

Tray rack

Normally, the autoclave should be used in conjunction with a tray rack, since this ensures that steam penetration and drying are as good as possible. In exceptional situations (e.g. when using sterilization containers from other manufacturers), and after consultation with your specialist dealer or with MELAG, the tray rack can be removed and the container can be placed directly in the autoclave chamber.

Trays

Trays for objects which are to be sterilized must be perforated, in order to get safe sterilization results and to allow condensation to run away. MELAG-trays are recommended. If you use dishes or trays without perforations, then the sterilization will not be safe and the autoclave will not dry properly.

Enclosed sterilization containers

Enclosed sterilization containers must be perforated on at least one side (preferably underneath) or must have valves, in order to ensure that steam can penetrate and condensate can run out. All MELAGsterilization containers meet these requirements with perforations on two sides a nd filter-cloth- inlays. Sterilization containers which only have perforations on the top only allow limited drying and are not for the use in the MELAtronic If sterilization containers are stacked in the autoclave, it is important to ensure that the perforations are not blocked.

Transparent sterilization packaging

If you use transparent sterilization packaging, such as MELAfol vertically on the tray. For the MELAtronic The packagings should never be laid flat one on top of the other. If seals split open during sterilization it may be necessary to increase the length of the impulse on the sealing device or to use a double-seal. Standard tray-cassettes sealed in MELAfol ensure that the side-seals do not split open.

Maximum loads

Do not exceed the maximum loads of the autoclave.

Mixed loads

If mixed loads of textiles and instruments are to be sterilized, then as far as possible the textiles should be above the instruments and direct contact with the instruments should be avoided. Inclusion of textiles and instruments in the same sterilization container is not desirable. Textiles should never come into direct contact with the walls of the chamber. If different types of packaging are included in a load, then:

• Instruments and sterilization containers should be at the bottom

• Transparent and paper sterilization packaging should be at the top (but lower than textiles)

Liquids

The appliance is not suitable for the sterilization of liquids!

Suitability for sterilization

Relevant information provided by manufacturers of instruments and textiles about sterilization should be strictly observed.
