[Music] disinfection and cleaning of suction systems the suction system is contaminated to a considerable degree with germs and dental materials which could lead to the formation of biofilm and a drop in performance or even to the failure of the unit therefore it is necessary to clean and disinfect the suction unit regularly eg with Aurra toll plus from der dental for the daily disinfection and MD 555 cleaner for the weekly cleaning please wear personal protective equipment and observe the occupational safety directives we recommend rinsing the suction system with two litres of cold water prior to every cleaning or disinfection process disinfect the suction hand pieces before you connect them to the adapters of the Oro cups the rinsing removes coarse particles from the system if necessary the spittoon can be cleaned between patients or prior to cleaning and disinfection measures with md5 50 from der dental disinfection of suction systems the disinfection solution must be dosed according to the manufacturer information up to two liters of ready to use solution can be prepared in the Oro cup care system from der dental we recommend the suction of one liter ready to use solution per treatment unit the Orica is a care system specially developed for suction systems it creates an ideal air solution mixture which contributes to effective cleaning and disinfection after the preparation of the solution 1 litre of the ready-to-use solution per unit is aspirated via the suction hoses with a filling level of 2 liters the Ora cup must be positioned upright during the suction of the first liter thanks to the sophisticated system the auro cap automatically stops the intake of liquid after 1 later with a filling level of 1 liter the Orica must be positioned horizontally the spittoon should be disinfected with at least 250 milliliters solution the system must not be rinsed with water during the exposure time the exposure time specified by the manufacturer must be observed to disinfect the suction system and to prevent the formation of biofilm the disinfection solution or atoll PLAs can remain in the system until the next restart of the assembly we recommend rinsing the system with two liters cold water prior to the first patient and following the expiry of the exposure time cleaning of suction units to dissolve acid soluble deposits such as scale or prophy powder we recommend using the acidic special cleaner MD 555 cleaner from der dental one to two times weekly a cleaning solution must be dosed according to the manufacturer information the cleaning should be preferably carried out during the lunch break thus the necessary time interval to alkaline reacting disinfection with or Atal plus is guaranteed and a mutual neutralization of the products is prevented after the preparation of the solution 1 litre of the ready-to-use solution per unit is aspirated via the suction hoses the spittoon must then be cleaned with at least 250 milliliters solution it is essential to adhere to the exposure times defined by the manufacturer in order to successfully clean the suction system the system must not be rinsed with water during the exposure time please note we recommend rinsing the suction system with two liters cold water prior to the cleaning or disinfection a time interval of at least two hours must be observed in order to prevent a mutual neutralization of the alkaline reacting disinfection with or Atal plus and the acidic cleaning with MD 555 cleaner please observe the exposure times at all times [Music] you
