Instruction Manual
8.1.8 Daily maintenance
of the hose holder system
After each treatment aspirate one glass of cold water.
For the cleaning and disinfection of the entire aspiration system, you
are instructed to us a material-compatible, non-foaming disinfectant
especially for aspiration systems (e.g. Orotol Plus).
It is recommended to disinfect and clean the aspiration system with
water twice a day.
Use a standard surface disinfectant to disinfect the hose holder. Regu-
larly clean and disinfect the surface of the components, e.g. with Dürr
Surface Disinfection FD 322 / FD 350 / FD 366.
Disinfect any used aspiration hand pieces after each patient and auto-
clave them if required to protect the dentist and the patient.
Please see the operating instructions of Dürr Dental which come with
the device for maintenance instructions.

Weekly maintenance
8.2.1 Spittoon – Changing the disposable filter
In order to minimize the danger of infection, it is essential to wear im-
permeable gloves when performing maintenance.
Change the filter once a week.
Remove the filter cover and extract the yellow disposable filter. Rinse
it under warm water or change and replace it. The filter has been desi-
gned for disposable use and is not suitable for autoclavation. It is heat-
resistant up to approx. 60°C.
Never work without filter, otherwise solid particles may get stuck at un-
suitable places in the drain and affect its function. Do not rinse the filter
in the spittoon as this may cause the drain to clog up. Always reinsert
the spittoon’s filter after cleaning or changing, in order to avoid clog-
ging caused by incrustation.
Re-order disposable filter 320.6508.01 (set of 12 pieces)
In order to facilitate the removal and insertion of the filter cover, we re-
commend to regularly lubricate the O-rings with 320.3981.01.
