Do I need to carry out periodic testing on my W&H Sterilizer?

All W&H sterilizers features test cycles (B&D/Helix test, Vacuum test). Compulsory and frequency of testing are regulated by local/national guidelines.

Who should I use to carry out validation and maintenance on my Lisa/Lina?

All validation and maintenance should be undertaken by the Competent Person (Decontamination) or Competent Person (maintenance).

Does my Lisa/Lina need to be commissioned from new?

Yes, validation is needed for new equipment at installation and annually thereafter. It will also be necessary to validate equipment after any major repairs have been carried out.

How long should I Keep periodic test records?

Under current national decontamination guildance, all audit documents should be stored for at least two years and they should not be removed from the premises or destroyed.

Do I need to document the results of all periodic tests?

Yes, all tests performed by the operator or user should be recorded in a logbook with the date and signature of the individual how carried out the test. Every Sterilizer and every thermo washer disinfector should have a logbook (file) in which test details pertaining to the lifecycle of the equipment (from purchase - disposal) are recorded. A logbook is provided as standard with the Premium Careplus Service Contract from W&H, or as an optional extra with the Premium Care Service Contract.

Validation is a series of tests carried out with the use of independent specialist test equipment, as is necessary to demonstrate that the physical conditions required for sterilization, thermal disinfection and/or cleaning (i.e. temperature, pressure, time) are achieved.

What water quality should I use with my Lisa/Lina?

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).

Should I pre-wrap and how long can I store my instruments after sterilization?

Under current UK decontamination guidance, with a type B vacuum cycle, instruments should be pre-wrapped and once sterilized can be stored for up to 12 months. Wrapping should take place shortly after washing and disinfection. Under current UK decontamination guidance, with a type N cycle, instruments should not be pre-wrapped. Once sterilized, instruments can be immediately aseptically wrapped and stored for up to 12 months. Instruments should always be dry before they are placed in the purpose-designed packaging.

What is the minimum shaft length of the bur for the S-11 Surgical Handpiece?

The shaft of the bur should be at least 44mm long (ISO-shaft 104).

What is the maximum noise level of the Lisa Mini sterilizer?

The max. noise level of Lisa Mini is 64 dB.

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.

How do I clean the water tank and what products should I use?

Water tank cleaning 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.

Is Lisa Mini requiring compressed air connection?

Lisa Mini requires compressed air connection to perform sterilization cycle. The compressed air specifications are available in the Instruction for Use, chapter “Technical data”.
