    The Lisa sterilizers

    From the outside
    Smooth surfaces, a fresh, ergonomic design – and an incredibly crystal clear colour display. The menu structure and the artificial intelligence behind it turns high end B type sterilizing into one of the most simple, comfortable and safest systems in the world. For full infection control within your daily work.

    From the inside
    So many elements, so much incredible technology and so many parts, completely integrated, in the right place and ready to serve and fulfil the daily requirements of a high end B type sterilizer!

    Incredible thanks to

    • EliSense: Thanks to LED indicators and display the outstanding technology offers cycle status information, temperature information and much more to optimise both workflow and output at a glance.
    • EliTrace: For the first time, the sterilization process can be traced and documented down to the individual instrument or instrument kit. Without additional software or computer.
    • Eco Dry+: Eco Dry technology adapts the drying time to the mass of the load. This reduces the cycle time, increases the life span of your instruments and optimises the energy consumption.
    • Intuitive interface
    • Perfect ergonomics
    • New environmentally friendly packaging
      The new environmentally friendly packaging is completely reusable and recyclable. Plastic components were reduced to a minimum. For 99% of its weight, the new package is made of cardboard and other fully biodegradable substances.

    EliSense

    Status Sense, Temperature Sense, Smart Sense: three incredible features, combined into EliSense.

    Cycle status information, temperature information and all information to optimise both workflow and output at a glance.

    EliSense Status Sense
    Shows you the cycle status of your sterilizer.

    EliSense Status Sense

    //a.storyblok.com/f/45617/385x402/bc6bbfa593/lisadisplay_image_left_385.jpg
    All the information you need at a glance:

    Cycle in progress
    The green lights flash.

    Cycle finished
    The green lights are static.

    Cycle Stop
    Occurs every time you manually stop during the cycle. The red lights flash.

    Cycle Stop finished
    The cycle error or manual stop has finished. The lights are static.

    Chamber temperature cold
    The load can be handled. The blue lights are static.
    EliSense Smart Sense
    Tells you what your sterilizer needs.

    EliSense Smart Sense

    Tells you:

    › When to replace Multidem

    › How to optimize drying

    › When it is possible to perform the vacuum test based on the temperature of the chamber

    › When the next tests depending on local legal requirements are needed

          • Should I pouch/wrap my instruments and how long can I store them after sterilization?
            To ensure that your instruments are stored in a sterile state from their successful sterilization until they are used, W&H recommends wrapping them in suitable sterile barrier systems before sterilization. The recommended storage period can be found in the recommendations of the wrapping material manufacturer. For further information, please contact your dealer. more
          • How do I change consumable components on my sterilizer?
            Consumable replacement instructions are provided in the Instructions for Use, chapter “Maintenance”. In addition, a video description is available: • in the sterilizer, in the maintenance section of the menu; • in the Consumables & Accessories and Video Tutorial section of this website. more
          • Who should I contact to validate and maintain my sterilizer?
            Validation shall be carried out by an official authority. Maintenance tasks shall be carried out by a qualified and authorised technician. more
          • Does my sterilizer need any periodic qualification/validation?
            Validation generally comprises a range of tests defined in internationally recognised standards. These tests begin for every device with the factory tests at W&H. In addition, corresponding documentation is included with your device. Prior to commissioning the device at your premises, the technician performs further checks to ensure the device functions correctly. Then, depending on the national/regional laws and directives, the device must be subjected to a so-called renewed performance qualification at regular intervals. For further information, please contact your dealer. more
          • How long should I archive the documentation of regular tests?
            Keep the results according to your country/regional specific laws and guidelines. Those records can be of assistance in case of service as well. more
          • Do I need to document the results of all periodic tests?
            W&H recommends recording all periodic tests, repairs, and modifications on the sterilizer in a logbook including date and signature of the person who carried out the test or other activity. Compulsorily of recording is regulated by local/national guidelines. more
          • What is validation?
            Validation is a testing procedure carried out by an official authority, proving the effectiveness of your sterilizer. Compulsories and frequency of validation are regulated by local/national guidelines. more
          • Warning about consumable replacement.
            POSSIBLE CAUSE
            A consumable needs to be replaced.
            SOLUTION
            Order the requested consumable (door seal and HEPA/bacteriological filter) and replace it. See the chapter “Maintenance” in the Instructions for Use. more
          • The sterilizer is connected to an automated water supply system, there is no clean water in the tank and the automatic water filling does not fill the water.
            POSSIBLE CAUSE
            Water filling system not connected.
            SOLUTION
            Connect the water filling system to the sterilizer. (see Instructions for Use).

            POSSIBLE CAUSE
            When the water filling system attempted to fill the tank, water was temporarily unavailable.
            SOLUTION
            Since the water tank filling is attempted only once in-between cycle execution, this event inhibits water feeding. Switch the sterilizer OFF and then ON again.
            Check the external water supply system.
            Check for water leaks from the sterilizer.

            POSSIBLE CAUSE
            Faulty MIN water level sensor in the clean water tank.
            SOLUTION
            Contact an authorised W&H service partner. more
          • The cycle report printer does not work.
            POSSIBLE CAUSE
            Printer not properly connected or not powered.
            SOLUTION
            Check the data and power connection to the printer. more
          • Warning about saving to the USB (HTML and SCL files)
            POSSIBLE CAUSE
            The USB drive is disconnected or full.
            SOLUTION
            Check presence and condition of the USB drive. If the problem persists, contact an authorised W&H service partner. more
          • Do I need to carry out periodic testing on my W&H sterilizer?
            All W&H sterilizers feature test cycles (B&D/Helix test, Vacuum test). Compulsory and frequency of testing are regulated by local/national guidelines. more
          • Which water quality should I use for my sterilizer?
            The water quality for sterilizers is internationally specified by standards and directives. The reasons for this are that your sterilizer can be seriously damaged by it or the sterilization can be jeopardised. Consequently, only water with conductivity of less than 10 µS/cm in North America and 15 µS/cm for the rest of the world should be used for your W&H sterilizer. The Water treatment devices Multidem and Osmo are especially designed to prepare suitable water (see chapter “Water quality” in the Instructions for Use). more
