4.2 PROGRAM 2. Wrapped Instruments and Porous Loads
For wrapped instruments and materials, when the manufacturer
recommends autoclaving at temperatures between 250F and 274F
(121C and 134C) with a drying stage.
Nominal parameters default settings
 Sterilization temperature: 273F (134C).
 Sterilization time: 7 minutes.
 Dry time: Models EA/EKA  30 minutes.
Models E/EK  60 minutes.
Operations sequence:
 Heating by actuation of electrical heaters until the sterilization
temperature is reached.
 Sterilization temperature is maintained constant for the preset
sterilization time.
 Fast exhaust, steam is exhausted out of the chamber at a fast rate until
pressure drops to 4 psi abs. (124 kpa abs.).
 Dry heating of chamber to remove leftover moisture from the
instruments and wraps, 30 minutes for models EA/EKA and 60 minutes
for models E/EK.
