  • Page 17: 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 18 Wrapped instruments should be packed in material that promotes drying such as autoclave bag, autoclave paper, and muslin towels. It is highly recommended to utilize the Tuttnauer Pouch Rack. This rack allows the operator to place pouches on their side, thus increasing the capacity of the autoclave significantly and promoting better drying of the instruments.
  • Page 19 Packs Place packs upright on trays, side by side. Packs should not touch the chamber walls. Pack instrument sets in a manner that prevents damage to delicate items. Pack hollowware sets so that all openings face the same direction and so that the contents cannot move inside the pack. Load packs of folded operating room drapes with layers vertical, allowing air to be removed from the packs rapidly.
  • Page 20 Liquids Use only heat-proof glass, filled to 2/3 capacity. Ensure that the glass container is covered, but not sealed to prevent pressure build-up. Liquids Note: A table of suitability steam sterilization process for various goods and methods of packing is included with accompanying documents.

    OPERATION To avoid possible damage, do not leave the autoclave un-attended while in operation 1. Ensure that the drain valve is in a CLOSED position. 2. Remove the water reservoir cover. 3. Pour distilled or mineral-free water into the reservoir through the opening on top of the autoclave until it reaches the base of the safety valve holder (the base must no immerse in the water.
  • Page 22 7. Set the multi-purpose valve knob to the FILL position. The water will now flow into the chamber. When the water reaches the mark at the bottom of the autoclave set the multi-purpose valve knob to the STE.(sterilize) position. Note: When used for the first time, the multi-purpose valve requires slight effort, but with use it will turn smoothly and easily.
  • Page 23 11. Set the STE. timer to the desired sterilization period according to the Sterilization Time Table (see table ahead). Recommended times for a, b, c are based on tests performed with a load according to Sterilization Load Test Table: Sterilization Load Test Table Loads Models 1730 2340 2540 3545 11.0 3850 13.6 3870 17.5...
  • Page 24 12. The POWER light is lit during the entire sterilization period, indicating connection to the power. The HEAT indicator signifies the operation of the pressure switch (B10), which keeps the temperature stable by connecting and disconnecting the heating elements. When the timer reaches 0, the sterilization process is complete and a buzzer will indicate that the cycle is complete.
  • Page 25 16.2 It is recommended to put the bottles on an un-perforated tray, which can be ordered at Tuttnauer, to prevent the clogging of the vessel opening in case the liquid starts boiling. 16.3 When the pressure decreases to “0” open the door and unload the autoclave.

    Checking the Safety Valve (Located in the water reservoir.) In order to prevent the safety valve from blockage, every two months, under ordinary usage, it is necessary to allow the steam pressure to escape through it. Checking the safety valve shall be performed during any cycle, when the pressure in the chamber is approx.
