CORRECT LOAD PLACEMENT
WARNING! Do not overload trays and the chamber. Adhere
to the maximum load weight limits (see "Sterilization
programs" on page 1).
Never place the load or the trays directly into the chamber
without the chamber rack as this could affect the steam
and temperature distribution. The load must always be
supported by the chamber rack.
Risk of burns. Before touching, ensure the sterilization
chamber is cold.
Wrap items with porous wrapping materials to facilitate steam
penetration and drying (e.g. sterilization bags for autoclaves).
Always use the chamber rack to allow adequate steam circulation.
Follow these requirements:
Load type Placement
Hinged instruments (e.g., In open position
forceps, extraction pliers, etc.)
Tubes Place tubes on a tray allowing the ends to
remain open. Do not bend tubes.
Cassettes can be placed vertically or horizontally
Cassettes
into the chamber rack (vertical placement
enhances drying). When placing cassettes
horizontally, slide them into the rack position
without putting them on trays (if size allows) to
enhance drying. When sterilizing double-decker
cassettes, place them in the lowest rack position
as there is more space height-wise.
