Dear doctor,
We thank you for your confidence demonstrated by the purchase of this autoclave.
More than 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 400,000 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 Technical description 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.
MELAG - General Management and employees
For physicians, physician's assistants, and service personnel
Please read this Technical description before you start operation of the autoclave.
The instructions contain important safety precautions. Make sure to keep the
Technical description near to the autoclave. The instructions are a part of the

Warning!
The autoclave is intended for use in every kind of general medical area
where no Class B autoclave is required due to the instruments used and
type of packaging.
According to →DIN EN 13060 this autoclave is considered a Class S
sterilizer. As a universal autoclave, it is suited for sterilizing wrapped
simple hollow body instruments (Hollow Body B) and smaller quantities of
textiles.
■ Use the autoclave only for the intended purposes outlined in the
Observe the following instructions for using the autoclave:

the sterilization of liquids.
In case of non-observance, the consequences could be →delayed

and components approved 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.

The autoclave sterilizes on the basis of the →pre-vacuum method
combined with the →fractionated flow method. These methods ensure the
complete and effective wetting or penetration of the items to be sterilized
with saturated steam. The procedure can also be used to safely and
quickly sterilize wrapped instruments or textiles.
To generate the sterilization steam, the autoclave uses an →integrated
steam generator. The sterilizer chamber is protected from overheating and
you can sterilize instruments and small quantities of textiles in a short time.
The cold chamber is preheated on activation of preheating or can be
maintained at a specific temperature between two sterilizations. This
shortens the program time periods and reduces the formation of
condensate to give improved drying results.

The autoclave works both according to the feed water one-way system as
well as the feed water circulatory flow system.
In the one-way system, it uses fresh purified feed water for every
sterilization run. The quality of the feed water is constantly monitored via
integrated conductivity measurement. This prevents stains on instruments
and soiling of the autoclave, provided the instruments have been carefully
prepared. In the feed water circulatory flow system, the autoclave works in
a more water-conserving manner, since the feed water is used for several
sterilization runs. The quality of the feed water is constantly monitored via
integrated conductivity measurement here as well.
The →feed water for generating the steam is automatically supplied via
an internal water storage tank or a water treatment unit (e.g. MELAdem
40, MELAdem
®
47).
The sterilized items are dried with the →pulsating overpressure and
vacuum drying method. 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 verifies pressure and temperature in the sterilization
chamber at all times and its door locking system does not permit opening
the door when there is overpressure in the chamber.
A →process evaluation system is integrated in the electronics of the
autoclave. It monitors the process parameters such as temperature, time
and pressure during a program. It monitors the parameters with respect
to their limit values at activation and control and guarantees a safe and
successful sterilization.
If one or more parameters are above or fall below the determined limit
values, the autoclave outputs a warning or fault messages and, if
necessary, aborts the program. In the event of an automatic program
abort, observe the information on the display.
With the help of the test programs, you can conduct an additional
function check at any time.
With the →Bowie & Dick-test, you can verify the autoclave for sufficient
steam penetration of porous sterilizing materials (e.g. textiles).
With →Conductivity measurement, you can verify the water quality of the
feed water.
The autoclave has an internal log memory which can save up to 40
program cycles. All data of the completed 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.

unit (e.g. MELAdem

sucks in the feed water.
If you employ the internal storage tank for the feed water supply, you must
fill it manually from time to time. At the given point in time, the autoclave
outputs an appropriate message. Only use water according to →VDE
0510 as →feed water.
The internal storage tank holds maximum 5 litres. This quantity of →feed
water suffices for up to 7 sterilizations.

With the MELAdest
65 distilling unit, you can produce →feed water in the
practice cost-effectively.
A water treatment unit is connected to the domestic water supply. It
produces the →feed water required for generating the steam for the
autoclave. The purified feed water connection for the autoclave is directly
connected to the water treatment unit.
If you use a water treatment unit, then there is always sufficient feed water
available. You no longer have to manually fill the water storage tank.
The waste water can either be collected in an internal storage tank and
manually emptied or automatically drained via the one-way drain.

In order to prevent water damage, MELAG recommends the use of a leak
monitor, e.g. water stop valve from MELAG (Art. No. 01056).
The autoclave is connected to the drain via the one-way drain (see page
10, Fig. 1/ (14)).
The connection must be located below the autoclave.
The one-way drain hose can be connected as follows:
To an existing sink drain
To a separate drain pipe when using the surface-mounted siphon
from MELAG (Art. No. 37410 – not in the standard scope of delivery)
You can reorder a 2-m long hose (Art. No. 36585) for the one-way drain
hose.
NOTICE:
The waste-water hose must be laid dip-free with continuous descent.
For waste-water paths which are longer than two metres we recommend a
fixed laying of HT (high temperature) piping by a specialised installation
firm.
Observe the following precautionary measures when handling the
mains cable and power plug:
■ 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 autoclave.
Mains cables or power plugs may only be replaced by →authorised
persons.
If these points are not observed, the cable or plug can be damaged
and/or a fire or electrical shock might occur. Serious injuries could
be the consequence.
