    IMPORTANT: Read this document to get the best understanding and to help ensure best performance of this equipment, which has been thoroughly inspected, tested and adjusted by factory-trained personnel. Equipment operation or maintenance other than described in the manual (unless by authorized representatives of the STERIS Corporation), shall be at the risk of invalidating the equipment warranty.
  • Page 14 The performance of the sterilizer is validated as a system including components defined by STERIS in the Operator and Maintenance Manuals 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 15 2 — Safety Precautions Repairs and adjustments to this equipment must be made only by STERIS or STERIS-trained personnel. Maintenance performed by unqualified personnel or installation of unauthorized parts could cause personal injury, result in improper equipment performance, void the warranty or result in costly damage.
  • Page 16 2 — Safety Precautions WARNING SLIPPING HAZARD To reduce slippery conditions, keep floors dry by immediately wiping up any spilled liquids or condensation in sterilizer loading or unloading areas. WARNING STERILITY ASSURANCE HAZARD Load sterility may be compromised if the Bowie-Dick test or air leak test indicates a potential problem. If these indicators show a potential problem, refer the situation to a qualified service technician before using the sterilizer further.
