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.

If you are not sure what the cause of the problem is, it is better to call the service station and talk to a technician. Together with the technician it can be determined what needs to be sent in and sometimes it is possible to even solve the problem right away.

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 jeopardized. Consequently, only water with conductivity of less than 15 µS/cm should be used for your W&H sterilizer. The Multidem system is especially suited to preparing suitable water (see chapter “Water quality” in the Instructions for Use).

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.

Lisa/Lara/Lina/Lyla/Lexa features test cycles (B&D/Helix test, Vacuum test). Compulsory and frequency of testing are regulated by local/national guidelines.

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.

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. Compulsories of recording is regulated by local/national guidelines.

The generator in the contra-angle handpiece requires at least 300 rpm to produce enough electricity for the LED. The rotary speed is between 15 and 50 rpm when positioning an implant.

No, the Implantmed/Elcomed motor does not need greasing. The motor bearings require no maintenance. Any additional greasing would reduce the service life of the bearings.

Yes, if the thermal washer disinfector has a drying cycle and the motor bears the sign that it is "Thermo washer disinfectable".

No. The new generation of motors have to be sterilized without cap.

Regular servicing of function and safety including the accessories is necessary and should be carried out at least once every three years, unless shorter intervals are prescribed by law. Detailed information can be found in the user manual at chapter "Servicing".

For propper tubing see "correlation of tubing" or user manual.

For applications which do not require accurate torque (drilling, grinding,…), any handpiece with ISO 3964 connection can be used. Please be informed that hand pieces from other manufacturers might not be able to handle the torque of your unit/motor and therefore might get damaged.

Not recommended. Due to different specifications (material, dimensions) it could cause problems like leakage, insufficient cooling or even damage the unit. For propper tubing see "correlation of tubing" or user manual.

Please find a detailed description in the user manual at chapter "Starting operation - General".

Please find a detailed description in the user manual at chapter "Hygiene and Maintenance".

Yes, it must engage audibly once, as otherwise the required torque is not achieved.

The user must replace the LED socket as soon as the protective coating on the LED discolours and the luminous power is impaired as a result. The length of time this takes can differ depending on the type of steriliser or sterilization process.

No
a. Different thread
b. Third-party device cannot find the correct resonance point – instrument fails to oscillate

The useful service life of the instruments is determined by the length of time they are used reprocessing and sterilization cycles have only marginal influence.

W&H Service Oil F1 has long­term stability between –30 oC and +160 oC.

Extensive research and testing produced a formula which best covers the extreme demands of dental instruments. It consists of an all-synthetic special oil of the highest purity supplemented by the specially developed additive package.

Check/replace the O-rings on the motor coupling/adapter (FAQ video Assistina O-rings). Ensure that the Start button is held depressed for at least 2 seconds when starting a programme. When the button is pressed, the green ball should be visible on the right in the functional display (cleaning solution). When the button is then released again, the green ball should be shown on the left. This procedure is also demonstrated in the FAQ video "Using Assistina". A detailed functional check can be found in the "weekly checklist" and in the "Test and functional check" section of the instructions for use.

Please find a detailed description about first startup, regular use and maintenance in the user manual. Furthermore you can find video tutorials about Assistina 301plus.

The pressure should be between 4 - 10 bar (58 to 145 psi).

Annually or if the filter is full of debris (visual check - filter should be white). Please see video about changing the filter).

All adaptors that are suitable for the Assistina 3x2/3x3 can also be used in the Assistina TWIN. There is only one exception: the RM/ISO adaptor for the Assistina 3x2/3x3 is not compatible with the Assistina TWIN. The HPI adaptor can be used for the Assistina TWIN instead.

During the maintenance process in the Assistina TWIN, the rotating parts are lubricated with oil and the spray channels rinsed with cleaning solution. These liquids are introduced to the handpieces using compressed air, which produces aerosols that may contain potentially contaminated body fluids (e.g. blood and saliva). In order to ensure that the apparatus poses no risk to the user, the patient or third parties, the law stipulates that aerosols must be prevented from leaking out of the apparatus. We make sure of this by using active suction and the HEPA filter. This HEPA filter must of course be changed regularly, which is why the lifespan of the filter is matched exactly to the capacity of the two cartridges. The HEPA filter therefore reaches the end of its service life once one set of cartridges has been used.

HEPA is short for 'High Efficiency Particular Air', and the filter is classified as HEPA class E11. This means that the filter retains all particles larger than 1 µm, which includes, among other things, a wide range of bacteria and viruses, suspended particles such as dust and respirable aerosols.

The intelligent process monitoring system documents the number of maintenance cycles that have been performed, thereby automatically calculating the number of instruments that can be serviced with the remaining quantity of fluid. The user receives an alert 300 cycles before the cartridge needs replacing (the oil and cleaner LEDs on the top of the unit turn yellow in colour).

The consumption volumes for each instrument are 0.07 ml of oil and 0.07 ml of cleaning solution. This gives a maximum capacity of 2857 cycles. In reality, the value is around 2800 to 2850 cycles, as initial filling is also required and the fill quantity of the cartridges is subject to certain tolerances that are regulated by the applicable standards.

The two cartridges and the filter can be changed easily without any tools. As with the Assistina 3x2/3x3, the fluid is supplied via tapping needles in the bottom of the cartridge spaces that penetrate the cartridge membrane, thereby drawing the fluid out of the cartridge. The two cartridges have different shapes to ensure that the two fluid types cannot be mixed up. In addition, it is only possible to install the HEPA filter incorrectly by using force, which is not necessary.

The oil is atomized in the Assistina TWIN before it is enters the instrument. This ensures full coverage of the gear parts, eliminating the need for technically complex and time-consuming rotational lubrication. However, there is no negative impact on the maintenance quality: the results of a maintenance operation correspond to those achieved with the Assistina 301 Plus.

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 jeopardized. Consequently, only water with conductivity of less than 15 µS/cm should be used for your W&H sterilizer. The Multidem system is especially suited to preparing suitable water (see chapter “Water quality” in the Instructions for Use).

Internal and external parts are of high quality stainless steel (including the contra-angle handpiece head).

Generally, prophylaxis contra-angle handpieces feature a seal on the head that prevents the ingress of saliva and paste. This extends the lifespan of the contra-angle handpiece.

The most effective removal of discolouration that at the same time protects the enamel and dentine as much as possible, depends on the polishing speed, i.e. revolutions per minute, among other things. With a speed ratio of 4:1 (four revolutions of the motor mean one revolution of the cup), the revolution speed of the Prophy cup is reduced. This means during application, there is no risk of paste splattering.

Yes, it is neccesary to properly adjust the air/water pressure and if applicable the voltage for the turbine.

If there is electricity at the end of turbine hose, you need a proper coupling and a turbine with light (example: RQ-24 and TK-97 L). If no electricity is available, the simplest way is to buy a W&H Alegra turbine with LED and its Roto Quick coupling (e.g.: TE-97 LQ and RQ-54). It doesn't require any other investment in the dental unit.

25 mm for the standard turbine (XX-98 modells) and 21 mm for turbines with small head (XX-97 modells). When using longer rotary instruments the user must ensure by correct selection of the operating conditions, that there is no danger to the user, patient or third parties.

Yes, the new generation of turbines can be operated with both the existing and the new couplings.

Yes, if your Primea Advanced Air Turbine is labelled with the symbol "thermo washer disinfectable".

It is not sufficient to purchase the Primea Advanced Air Turbine alone. In order to be able to operate it, you need the entire Primea Advanced Air System – consisting of a turbine, control system, user interface (UI) and the supply hose with Roto Quick coupling. You can add this as an add-on or built-in solution to/in your dental unit.

W&H can offer you the Primea Advanced Air System as an external add-on which you can connect to your dental unit. To do this, you need a spare supply hose for your dental unit, a minimum operating pressure of 5 bar and the possibility to connect the control system to the mains power supply.

For detailed instructions, see the chapter "Hygiene and maintenance" in the respective instructions for Use.

The built-in electronic components do not need to be serviced separately. However, regular servicing should be carried out together with the dental unit at the legally required intervals. This will ensure the proper functioning and safety of the components. For details, see the chapter "Service" in the respective instructions for Use.

Regular servicing of the Primea Advanced Air Add-on including the accessories should be carried out at least once every three years, unless shorter intervals are prescribed by law. The regular service must only be performed by an authorised W&H service partner. For details, see the chapter "Service" in the respective instructions for Use.

This is possible. In order to operate standard turbines (from W&H and other manufacturers), the control system of the Primea Advanced Air System can be changed over to standard turbines mode. Turbines which can be connected to the standard 6-hole connection are then operated with a constant 3 bar operating pressure.

In "Power" mode, the set speed is also constantly maintained when pressure mounts on the rotary instrument, which translates to a higher removal rate. The "Tactile" mode permits a reduction in the removal rate when pressure mounts on the rotary instrument.
