According to DIN EN 13060 this steam sterilizer is considered a Class B
Observe the following instructions for using the steam sterilizer:
■ Use the steam sterilizer only for the intended purposes outlined in
Universal use
The steam sterilizer sterilizes on the basis of the fractionated pre-vacuum
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
practice.
Large quantities
To generate the sterilization steam, the steam sterilizer uses a separate
steam generator. At program start, steam is generated and conducted
into the sterilization chamber. A defined pressure and a prescribed
temperature is thereby given. The sterilization chamber is protected from
overheating and you can conse

devices and components approved by MELAG.
■ The sterilization of instruments and textiles with this steam sterilizer,
like the foregoing instrument preparation, 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 steam sterilizer and/or to the items to be sterilized.

■ After disinfection and cleaning, rinse the instruments if possible with
demineralized or distilled water and subsequently thoroughly dry the
instruments with a clean, non-fuzzing cloth.
■ Employ only cleaning materials which are suitable for steam
sterilization. Ask the manufacturer about the cleaning materials.
In case of non-observance, residual dirt can possibly be loosened
up during sterilization in the steam pressure. Rests of the
disinfection and cleaning agents lead to corrosion. Increased
maintenance requirements and impairment of the function of the
steam sterilizers can be the consequence.
Unsuitable cleaning materials, e.g. water-rejecting cleaning
materials or steam-impermeable oils, can result in unsterile
instruments. This endangers your health and the health of your

Air leakage – checking the air leakage
Air leakage is a poorly sealed location through which
unwanted air can enter or escape;
Checking the air leakage serves to verify that the volume
of the air leak in the sterilization chamber during the
vacuum stages does not exceed a value where it would

that the air leakage is not a possible cause of a renewed
contamination of the sterilizer load during drying
