Note

The liquid cycle is not designed for
sterilization of liquids in a clinical
application. Do not prepare sterile
liquids for in vivo applications with
the Sterilemax system.

Dental handpieces should be run
in the optional cycle at 132°C for
10 minutes. Refer to manufactur-
er's recommendations for contra
indication of sterilization parame-
ters.

When sterilizing handpieces, refer
to the manufacturer's specifica-
tions on handpieces for contra
indication of sterilization parame-
ters.

Operational Programs

The sterilizer has four preset cycles which have been opti-
mized to provide excellent results for most applications. In
addition, there is one optional cycle that allows you to set
your own sterilization parameters. You access the pre-pro-
grammed cycles by pushing one of the four green fixed-cycle
buttons. The four preset sterilization programs are:

Unwrapped Goods

For unwrapped instruments and items made of metal,

glass or plastic. Parameters: 3 minutes at 135°C.

Wrapped Goods

For wrapped packs of clothes, bandages, pads, fabrics,

rubber tubing and metal instruments. Parameters: 10 minutes
at 135°C.

Liquids

For distilled water, media solutions and other liquid pre-

pared in closed bottles or flasks. Parameters: 15 minutes at
121°C.

Packs

For packs of instruments and towels and other packed

goods. Parameters: 30 minutes at 121°C.
