The performance of the sterilizer is validated as a system including components defined by STERIS in the Operator Manual and Service Manual for the sterilizer. Substitution of unauthorized components can potentially lead to personal injury, damage or premature failure of the product and result in a unit configuration that is inconsistent with the validated product.
Page 22
Actuation at less than 75% of rated pressure can allow debris to contaminate the seat and cause the safety valve to leak. A leaking safety valve must be replaced. Insufficient service clearance will make repairs more difficult and time-consuming. Piping sized too small may cause water hammer, resulting in damage to the sterilizer. After installation, it is mandatory to brace piping at the drain funnel so that it will not move vertically.

4.7 Techniques of Sterilization for Liquid Cycle WARNING – EXPLOSION HAZARD: This sterilizer is not designed to process flammable compounds. WARNING – PERSONAL INJURY HAZARD: Avoid personal injury from bursting bottles. Liquid sterilization cycle must only be used for liquids in borosilicate (Pyrex) flasks with vented closures. WARNING: The liquid cycle is for non-patient contact use only.
4.8 Recommendations Important: Read the following paragraphs before sterilizing any liquids in your sterilizer. The liquid cycle is for non-patient contact for Sterilizing Liquids use only. WARNING – EXPLOSION Containers of liquid must be located at least 4" (102 mm) from the HAZARD: The liquid cycle is sterilizer chamber door(s).
4.9 Sterilization of A healthcare facility must develop adequate monitoring practices for sterilization implantable devices. Refer AORN Implantable Devices recommended practices for more information. Sterilization of implantable devices by a healthcare facility must be monitored: • When sterilizing an implantable device, always place a biological monitor in the load.
