Dear doctor,

We thank you for your confidence demonstrated by the purchase of this autoclave.

Over 55 years ago, MELAG began as a medium-sized family-run enterprise to specialise in the
manufacture of sterilization equipment for medical practices. In the meantime our company has grown
into one of the world's leading producers of sterilization equipment. Verification of it success has been
the sale of more than 410,000 MELAG units worldwide, attesting to the high quality of our sterilizers,
which are exclusively made in Germany.

This autoclave has also been manufactured and tested according to the most stringent quality criteria.
Nevertheless, please read the Operating Instructions carefully before the initial start-up of the device.
The long-term serviceability and the retention of value of your autoclave depend primarily on the
careful preparation of the instruments and the regular maintenance of the device.

Chapter 1 – Performance Specification

In this chapter you learn

 under which conditions and for which purpose you should use this autoclave
 what benefit you can achieve by using this autoclave
 which sterilization programs you can use

Proper use

Application area The autoclave is intended for use in the medical field, e.g. in general

physician and dental practices.

Sterilization tasks According to →DIN EN 13060 this autoclave is considered a Class B

sterilizer. It is suited as a universal autoclave for demanding sterilization
tasks. For instance, you can sterilize narrow-bore instruments and
transmission instruments – wrapped or unwrapped – and larger quantities
of textiles.

Dange

Attention

Universal use The autoclave sterilizes on the basis of the →fractionated vacuum

Large quantities

Small time expenditure

No pause times

Overheating protection

Clean feed wate

Observe the following instructions for using the autoclave:

■ Do not sterilize any liquids with this autoclave. It is not approved for
the sterilization of liquids.

In case of non-observance, the consequences could be →delayed boiling,
damage to the autoclave and burns.

■ Use the autoclave only for the intended purposes outlined in the
related technical documents and only in connection with the devices
and components recommended by MELAG.

■ The sterilization of instruments and textiles with this autoclave, like the
foregoing instrument sterilization, is only to be done by competent
personnel.

■ Only use instruments, wrappings and textiles which are suitable for
steam sterilization according to the manufacturer's information.

In case of non-observance the consequences can entail damage to the
autoclave and/or to the →items to be sterilized.

User benefit

method. This ensures the complete and effective wetting or penetration of
the →items to be sterilized with saturated steam. This method makes it
possible to sterilize all kinds of loads which occur in a physician's medical
practice.

To generate the sterilization steam, the autoclave uses a →double jacket

steam generator. Once heated up, it provides permanent steam. The walls
of the →sterilization chamber thus have a defined temperature. The
sterilization chamber is protected from overheating and you can
consecutively sterilize large quantities of instruments or textiles very
rapidly and achieve excellent drying results.

The autoclave works with a one-way feed water system. This means that it

uses fresh purified →feed water for every sterilization run. The quality of
the feed water is constantly monitored via integrated →conductivity

documentation

The supply with purified →feed water for the steam production is

automatically provided from an internal supply tank or a water treatment

unit (e.g. MELAdem® 40, MELAdem

®

47).

The →items to be sterilized are dried by the →vacuum. (→vacuum

drying). This way you achieve optimal drying results for wrapped objects
as well.

The autoclave works with an →electronic parameter control. This way the

time

autoclave optimizes the total operating time of a program depending on
the load.

The autoclave checks the pressure and temperature in the sterilization

chamber at all times and does not permit the door to be opened in case of
overpressure in the chamber. The motor-operated automatic door lock
opens the door by slowly turning the locking spindle and holds the door
while it opens. Pressure compensation takes place even if there is any
difference in pressure until the door is completely opened.
The quantity and quality of the →feed water is checked.
A →process evaluation system is integrated in the electronics of the
autoclave. During a program it compares such process parameters as
temperatures, times and pressures with each other. It monitors the
parameters with respect to their limit values at activation and control and
guarantees a safe and successful sterilization.
A monitoring system checks the device components of the autoclave with
respect to their functional reliability and their plausible interaction.
If one or more parameters exceed defined limits, the autoclave issues
warnings or error messages, and if necessary aborts the program. In the
event of an automatic program abort, observe the information on the
display.

You can conduct an additional function check at any time with the help of
test programs.
Use the vacuum test to check the autoclave for leaks in the steam system.
Use the →Bowie & Dick test to check whether there is sufficient steam
penetration for porous material to be sterilized (e.g. textiles).

The autoclave has an internal log memory. All data of the completed

sterilization programs are automatically stored here.
You can read out the internal log memory immediately after the end of the
program, or at a later time. You determine whether the logged data are
issued to one or several different output media (e.g. log printer

MELAprint

42, MELAflash CF card, computer).

■ Never splice or modify the mains cable.

■ Never bend or twist the mains cable.

■ Never pull on the mains cable to take it out of the socket. Always take

hold of the power plug itself.

■ Never place any heavy objects on the mains cable.

■ Never run the mains cable over places where it could be squeezed

(e.g. doors or windows).

■ Do not run the mains cable along a heat source.

■ Do not use any nails, staples or similar objects to fixate a cable.

■ If the mains cable or the power plug is damaged, turn off the

The internal supply tank holds maximum 5 liters. This quantity of →feed

water suffices for up to 7 sterilizations.
