  • Page 8: Safety Instructions

    SAFETY INSTRUCTIONS The autoclave has unique characteristics. Please read and understand the operation instructions before first operation of the autoclave. The following issues may require instructions guidance provided by the manufacturer: how to operate the autoclave, the door safety mechanism, the dangers involved in circumventing safety means, how to ensure that the door is closed, and how to select a correct sterilization program.
  • Page 9 Open the door slowly to allow steam to escape and wait 5 minutes before you remove the load. When sterilizing liquids, wait 10 minutes. Once a month, ensure that the safety valves are functioning, and once annually a certified tester must conduct pressure chamber safety tests. Once annually, or more frequently, effective tests must be performed, i.e., calibration and validation.

    3.11 Water Quality 3.11.1 Water for Steam Generation The distilled or mineral – free water supplied to the autoclave should have the physical characteristics and maximum acceptable level of contaminants indicated in the table below: Physical Characteristics and Maximum acceptable contaminants levels in steam for sterilizers (According to EN 13060:2004).

  • Page 19: Safety Features

    3.11.3 Reverse Osmosis A Reverse Osmosis (RO) system may be used to improve the quality of the water used to generate steam in the autoclave chamber. In RO, the water is forced through a semi-penetrable membrane, which filters out contaminants to a high degree of efficiency. In deionisation (DI) ions and charged particles are removed either by electric fields or by ion exchange in resin beds.

  • Page 71: Preparation Before Sterilization

    PREPARATION BEFORE STERILIZATION The purpose of packaging and wrapping of items for sterilization is to provide an effective barrier against sources of potential contamination in order to maintain sterility and to permit aseptic removal of the contents of the pack. Packaging and wrapping materials should permit the removal of air from the pack, penetration of the sterilizing water vapor into the pack and removal of the sterilizing vapor.

  • Page 72: Liquids

    9. Once a week, use a biological spore test indicator in any load to make sure sterilization is performed. 10. Make sure that all instruments remain apart during the sterilization cycle. 11.

Pressing the START/STOP key at any stage of the process stops the operation. If the cycle was aborted before completing the sterilization stage, it will leave the load unsterilized.
  • Page 76 10.11.2 Loading Correct loading of the autoclave is essential to successful sterilizing for several reasons. Efficient air removal from the chamber and the load will permit effective steam penetration and saturation, and allow proper drainage of condensate. Additionally, correct loading will prevent damage to packs and their contents and maximize efficient use of the sterilizer.

  • Page 77: Door Safety System

    DOOR SAFETY SYSTEM The door safety consists of two safety means: 11.1 Pressure switch and Locking solenoid While at “stand-by” mode and the pressure in the chamber is less than 10 kPa above ambient pressure, the solenoid’s pin is retracted. The autoclave is equipped with a NC 10 kPa (1.4 psi) pressure switch that is connected to the chamber.

    SERVICE AND MAINTENANCE 12.1 Preventive Maintenance The maintenance operations described in this chapter must be fulfilled periodically in order to keep the autoclave in good working condition and to reduce the breakdown time to a minimum. The user’s maintenance personnel, according to the following instructions can easily execute these operations.

  • Page 79: Checking The Safety Valve

    12.2 Checking the Safety Valve The safety valve is located on the rear side of the autoclave In order to prevent the safety valve from a blockage, operate it once a month. 12.2.1 PED-approved type safety valve Operate the sterilization cycle according to the manual. Allow a pressure of approximately 200 kPa (29 psi) to build up in the chamber.
  • Page 80 12.2.2 ASME-approved type safety valve Operate the sterilization cycle according to the manual. Allow a pressure of approximately 200 kPa (29-psi) to build up in the chamber. Operate the safety valve by pulling the ring of the safety valve using a tool, i.e. screwdriver, hook etc and lift the safety valve ring for 2 seconds.
