## Indications for use
The SYSTEM IE Liquid Chemical Sterilant Processing System is intended for liquid chemical sterilization of cleaned, immersible, and reusable critical and semi-critical heat-sensitive medical devices in healthcare facilities. The SYSTEM IE Processor dilutes the S40 Sterilant Concentrate to its use dilution (>1820 mg/L peracetic acid), liquid chemically sterilizes the load during a controlled 6-minute exposure at 46 to 55°C, and rinses the load with extensively treated* potable water. The processed load should be used immediately. The SYSTEM IE Processor uses only S40 Sterilant Concentrate to liquid chemically sterilize medical devices. *The extensive treatment of EPA potable water consists of: 1. Pre-filtration through two pre-filters: * Pre-filter 1 is a gross depth filter that removes approximately 5 micron or larger particles/contaminants. * Pre-filter 2 is a surface filter that removes particles/contaminants > 0.1 micron. 2. UV Irradiation: * During transit through the UV water treatment chamber, a UV dose sufficient to achieve a >6-log reduction of MS2 virus is delivered to the water. 3. 0.1 micron filtration: * The water prepared by pre-filtration and UV irradiation is filtered through redundant, 0.1-micron (absolute rated) membranes to remove bacteria, fungi and protozoa >0.1 micron.
