3.6 Record of installation and setting up
____________________________________
As documentation that the autoclave has been set-up properly, a record of installation and setting up should
be produced by an authorised person and a copy sent to MELAG. This is important in the event that you
wish to make claims under warranty provisions.
3.7 Validation __________________________________________________________
In accordance with EN 17665, the sterilization process should be validated before beginning routine
operation with the autoclave.

Sterilization
4.1
Supply with fresh purified feed water/cooling water
______________________
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 malfunction messages or interruptions of programs
•
Before the first sterilization at the start of the working day, check that the water supply is turned on (water
tap),
•
If purified feed water is drawn from a storage container, check the water level, and if necessary fill up with
purified water of appropriate quality (see section 7.4),
•
If the feed water is drawn directly from a MELA
dem
®
55 water treatment unit, check that its water supply
is turned on in good time (this may be up to an hour before starting a sterilization program), if the water
supply has been turned off over night, for example.
•
For routine operation, please refer to the information contained in section 10.
4.2 Preparation of instruments
____________________________________________
MELAG non-rusting materials
All parts of the Cliniklav
®
25 which come into contact with steam are made of non-rusting material. The
autoclave chamber and the steam conducting parts are made of stainless steel, the door is made of
anodised aluminium and the threaded fittings and solenoid valves are made of brass.
Drag-in rust
The use of non-rusting materials excludes the formation of rust as a result of the components of the
autoclave. Where rust forms on the autoclave or the items to be sterilized, investigations have repeatedly
shown that this rust has been brought in from other sources. It should be borne in mind that rust can form
even on best quality stainless steel instruments, for example as a result of improper treatment with chemical
cleaning agents or disinfectant during preparation for sterilization.
Preparations of items for sterilization
The example of drag-in rust shows how important it is to prepare items properly for sterilization, and
particularly the following points.:
Handpieces and angles should be cleaned before the sterilization in accordance with the manufacturers
instructions and maintained (e.g. oiled). The remaining instruments should be disinfected and cleaned
immediately after use in accordance with UVV/VBG 103 with a disinfectant and/or cleaning solution. The
solutions should be used in the correct concentration and care should be taken to observe the immersion
times precisely!
It is advisable to make use of appropriate cleaning aids such as ultrasonic cleaning units, cleaning and
maintenance equipment for handpieces and contra-angles, or thermo-disinfecting systems.
Cleaning the instruments before sterilization is very important in order to avoid introducing contamination
which can separate from the instruments under steam pressure during sterilization and block filters, jets and
valves of the autoclave. In particular, locks, joints and hinges should be thoroughly cleaned with a brush.
Cleaning and disinfecting agents should be washed off the instruments thoroughly in running water, again
with a brush. Residues of cleaning and disinfectant chemicals must not find their way into the autoclave,
since they can lead to corrosion! Swill finally with demineralized water and then dry the instruments.
Turbines and transfer instruments should be oiled in accordance with manufacturer's instructions in order to
ensure a long life for these components.
Brand-new instruments
The cleaning procedures described above are also necessary for brand-new instruments, since these often
carry very small amounts of oil, fat and soiling from the manufacturing process.
