  • 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.
  • Page 10: Technical Data

    TECHNICAL DATA Introduction Models 3840, 3850, and 3870 ELV/ELVC are vertical sterilizers designed especially for sterilization of instruments, liquids and other materials in hospital laboratories, medical laboratories, research institutes, food laboratories and pharmaceutical facilities. A special feature of this sterilizer is the fast cooling operation, provided as an option for the liquids sterilization cycle.
  • Page 11: Operating Conditions

    Operating Conditions  The autoclave is intended to work in ‘indoor’ conditions only.  Only autoclavable materials shall be used.  The environment shall not exceed an ambient temperature range of 5ºC (41ºF)-40ºC (104ºF) and a relative humidity of 85% respectively.

    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.

    3.13 Description of Operation 3.13.1 Heat The ELV vertical autoclaves are equipped with immersion type, heating elements. After water has been introduced to the chamber and the unit has been activated, the heating elements begin to heat. The temperature and pressure in the chamber increase until appropriate levels are reached.
