    2. 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 11 On closing the autoclave's door, make sure it is properly locked before activating. Before withdrawing baskets, wear heat resistant gloves. Before opening the door, verify that there is no pressure in the chamber (chamber pressure gauge is located on the autoclave's front panel or door, depends on model).

  • Page 73: Preparation Before Sterilization

    9. 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 74: Liquids

    Place instruments with ratchets opened and unlocked or clipped on the first ratchet position. Disassemble or sufficiently loosen multiple-part instruments prior to packaging to permit the sterilizing agent to come into contact with all parts of the instrument. Tilt on edge items prone to entrap air and moisture, e.g. hollowware, so that only minimal resistance to removal of air, the passage of steam and condensate will be met.

    10. Operation 10.1 Draining and filling the water reservoir (WR only). Drain the water from the mineral free water reservoir once a week, and refill with fresh mineral-free water or distilled water 10.1.1 Draining Caution! Before starting, Make sure that the electric cord is disconnected and there is no pressure in the autoclave.

  • Page 76: Turning On The Autoclave

    Caution! Use only water having the characteristics as per table in sec 3.11. Tap water may clog the system. A clogged system causes increase of pressure, which prevents temperature from rising. Turn on the main power switch. Caution! Under no circumstance should water be filled above the cooling coil.
