7. Operating the sterilizer - general information
7.1. Preheating the chamber
After switching on the unit it is in a wait modus. After activating a program the unit changes into a
standby modus and activates automatic preheating function. This function is automatically preheating
the steam generator if the lid is closed. Jacket preheating starts in special programs only if it is
activated.
If the door / lid is open, the automatic preheating is disabled!
7.2. Preparation of sterilization goods
Solid sterilization goods should be cleaned before sterilizing. Cleaning is a basic part of sterilization
process. It reduces the numbers of microorganism on the surface. The sterilization is not a cleaning
process! Microorganism will be killed or deactivated but the rest of material that the microorganism
consists of will be on the surface after the sterilization has finished! Often these particles act as
pyrogenes!
Solid sterilization goods should be cleaned before
sterilization! Only this gives warranty of a high quality
sterilization cycle!
For wrapping the sterilization goods the wrapping material should be convenient to use as wrapping
material! The wrapping should be closed over the complete cycle to protect the goods against
recontamination after sterilization has finished. For waste material in a waste bag the opposite is
valid. Waste bags should be opened or should open under vacuum! This is necessary to make sure
the steam comes in direct contact with sterilization good. If there are doubts that the sterilization
process runs without complications it should be validated!
Wrapped and porous material should be sterilized with
vacuum program only! Waste bags are a kind of wrapping
material! To sterilized waste in a waste bag a vacuum
program is the best deaeration process. Pressure purge
process may be not enough for good deaeration.
Especially when sterilizing wrapped goods it is necessary to keep the load in the same kind it was
validated. The single packages should not lay inside to close to the next. Deaeration and drying
function depend on the kind of loading! If the steam can not reach the good evenly spread , the
heating power will create temperature differences!
Heavy good should lay on the ground of the chamber, lighter goods should lay upstairs. In each
program cycle the loads should be from the same type. The deaeration type should respect the
heaviest and most complicate load! A mixture of solid and liquid loads should be avoided.
