Six steps to your customized sterilizer:
- Purchase the Activation Code of your choice from your local approved dental supplier.
- After receiving the related login code, go to activation.wh.com
- Specify this code along with the serial number and model of your sterilizer.
- Your individual, secure Activation Code is generated.
- Enter this code in the menu of your sterilizer.
- The feature is available.
Step 1
Collecting dataCollecting data
The first step towards full traceability is creating a database of all instruments and kits. This can be done directly by touching the screen – but also via PC or W&H Steri App. Different types of instruments and kits are pre-set.
But there is also the possibility to create individual ones.
Step 2
Load identificationLoad identification
There are three ways for load identification.
The first way: You pre-print a certain number of related barcode labels and place them in an organizer. When it comes to sterilizing, simply attach the related barcode label to the pouch and scan it. Now the EliTrace system knows which instruments or kits are in the pouch.
The second way: You print one label per instrument or kit, keeping them to have them ready at any time.
During loading, you scan and then print the final label to be added to the pouch.
The third way: Directs you to the display, where you select the related product or kit. Then all you have to do is press the print button on the display to get the related barcode label printed.
Step 3
RetrievalRetrieval
After storing the sterilized instruments in their pouches, a simple scan of the barcode labels when at the dentist´s chair shows you and your patient when the instruments or kits have been successfully sterilized.

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
-

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

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 max. noise level of Lara is 66.9 dB. The max. noise level of Lara XL/Lexa Plus is 70 dB. 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
