Instructions for all sterilization procedures

Electricity and water supplies
________________________________________
4.1.1
Cooling water and purified feed water _______________________________________________
The autoclave automatically monitors the availability of cooling water and purified water, as well as the quality
of the distilled / demineralised water before starting a program.
In order to allow an immediate program start and to avoid error reports or interruptions of programs (see
Sections: 7.3 and 0):
Before the first sterilization at the start of the working day, check that the water supply is turned on (stop
cock)
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 8.3.2)
If the feed water is drawn directly from a MELAdem
®
47 water purifier, 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.
4.1.2 Power
supply ___________________________________________________________________
Switch on the power using the switch on the front of the autoclave (bottom right). About 15 seconds after the
message "Please wait Door release“ the appliance is in the start status:

Loading the autoclave
_______________________________________________
It is of crucial importance for effective sterilization and good drying that the autoclave is loaded properly:
Tray rack
For the Vacuklav
®
24-B/L there are 2 types of tray rack:
Type "B" (MELAG-Art.-No.: 40224) for up to 4 trays or 4 standard tray-cassettes.
Type "C" (MELAG-Art.-No.: 40242) for up to 6 trays or 3 standard tray-cassettes.
Both types of tray rack are also suitable for the MELAG-sterilization containers Type 15K,M,G;
Type 17K,M,G,R; Type 23M,G,R, Type 28 M,G.
Normally, the autoclave should be used in conjunction with a tray rack, since this ensures that steam
penetration and drying are as good as. 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 allow condensate to run away.
MELAG-trays are recommended. If you use dishes or trays without perforations, then the objects being
sterilized 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 MELAG-sterilization
containers meet these requirements with perforations on two sides and filter-cloth- inlays.
Sterilization containers which only have perforations on the top only allow limited drying.
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
®
, then the items should if possible be stood
vertically on the tray, or sterilized in foil holders (MELAG-Art.-No.: 22420). They 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 sealing impulse or to
use a double-seal.
Standard tray- cassettes sealed in MELAfol
®
(250 mm wide) must be taped and clasped additionally to ensure
that the side-seals do not split open.
Multiple wrapping
The pulsed vacuum method means it is possible to use multiple wrapping.
