High-level disinfection

The G 7881 Dental Thermal Disinfectoris suitable for automatic treatment ofdental instruments and accessories. Itcleans and in the disinfection programsimultaneously thermally disinfects, at200°F/93°C, instruments andaccessories.

Areas of effectiveness are physicalremoval or thermal inactivation ofvegetative bacteria includingmycobacteria, fungi, fungal spores, andviruses. These categories include theMycobacterium tuberculosis and theEnterococcus faecium.

Important: Only the programs labeled"Disinfection" disinfect! Only use thisprogram when handling contaminateditems. All other programs are designedto clean items without disinfectingthem.

All relevant safety procedures shouldbe obeyed. Relevant safety proceduresinclude, but are not limited to, theCenters for Disease Control’sRecommended Infection ControlPractices for Dentistry and the OSHABloodborne Pathogens Standard.

The G 7881 Dental Thermal Disinfectorachieves high-level disinfection asdefined by the Spauldingcategorization.

The Spaulding category high-leveldisinfection is the same type of meansas in the sterilant category except thatthe use pattern is different. The sterilantis used as a high-level disinfectant bye.g. reducing the exposure time withinits effective range of tuberculocidal,virucidal, and bactericidal action.

According to the Centers for DiseaseControl’s Recommended InfectionControl Practices for Dentistry,instruments should be classified in oneof the following categories and betreated accordingly:

All critical instruments must besterilized after treatment in the G 7881Dental Thermal Disinfector. Criticalinstruments are used to penetrate softtissue or bone, e.g. forceps, scalpels,bone chisels or scales.

Semicritical instruments should besterilized after treatment in the G 7881Dental Thermal Disinfector. If however,sterilization is not feasible because theinstrument will be damaged by higherheat exposure, the instruments may betreated thermally in the G 7881 DentalThermal Disinfector. Semicriticalinstruments do not penetrate softtissues or bone but contact oral tissues,e.g. mirrors and amalgam placementinstruments.

Noncritical instruments may betreated thermally in the G 7881 DentalThermal Disinfector. Noncriticalinstruments or devices come intocontact only with intact skin, e.g.external components of x-ray heads.

Instruments suitable for processingin the thermal disinfector

In general, only high quality stainlesssteel instruments are suitable forprocessing in the G 7881. Allinstruments, accessories and otheritems to be cleaned and disinfected inthe machine should have the followingproperties:

– heat resistance to a temperature ofup to 95°C / 203°F.

– corrosion resistance in the presenceof heat and alkalinity.

The heat retention capacity of stainlesssteel allows for fast drying. Plastic has alower heat retention capacity, thusrequiring a longer drying time. In thiscase, a slightly extended waiting periodof 5-15 minutes may be necessary afterthe disinfection cycle.

Aluminum instruments may discolorduring the cleaning process. Aluminumhas only a limited suitability forprocessing in this system.

Carbon steel and chrome-platedinstruments may corrode during thecleaning process. Processing thesetypes of instruments in the G 7881 isnot recommended.

Hand pieces, drill bits, grinders, rootcanal instruments or other rotatinginstruments are not suitable for thethermal disinfector. Do not processthem in the thermal disinfector.

Do not clean fiberoptics or electricalequipment and components in thethermal disinfector.

Rhodium coated mirrors must bearranged so that their surfaces do notsuffer any mechanical damage. Not allspecula with glass are suitable formachine treatment.

If you have questions regardingwhether an instrument is suitable forprocessing in the G 7881 DentalDisinfector, please seek the advice ofthe instrument manufacturer.

Water quality

Good water quality is essential forprocessing instruments in the dentalwasher disinfector. Otherwise,instrument corrosion may result.

Poor water quality consists of, but is notlimited to, high concentrations ofchlorides (over 50 ppm). High chloridelevels will cause even high qualitystainless steel instruments to rust whenprocessed in the machine. Othereffects that may be noticed aretarnishing or "blueing" of instrumentsdue to dissolved minerals in the water.

If you notice any of the abovesymptoms in your instruments, pleasecontact a Miele ApplicationsSpecialist at:

Correcting minor faults

44

Unsatisfactory cleaning results

Unsatisfactory cleaning results mayoccur as drying spots, or as spots thatlook like corrosion. Presumably,corrosion spots are often bio-debris.They have the shape of drying spots,blurry edges and a rust color.Bio-debris may also appear onsurfaces that were not contaminatedbefore processing. To remedy thisproblem:

^ Run the machine within six hours ofloading, even if it is partially loaded.

^ Check the dosage of the detergentand adjust. Too little or too muchdetergent may deteriorate cleaningresults.

^ Rearrange the load to be cleaned sothat the spray arms can rotate freely.

^ Check if anything obstructs thepowdered detergent dispenser flap.

^ Make sure that the water connectionspring adapter engages correctlywhen a basket or injector unit isinserted in the machine. It must be4-5 mm higher than the waterconnection inlet. If it is not:

– Loosen the plastic nut.

– Push up the adapter (4-5 mm higherthan the water connection inlet) andtighten the plastic nut.


45

The water in the wash cabinet is notheated or the program sequencelasts too long (fault code "F01-F03,F18, F19" appears in the display)

The machine has a resettabletemperature limiter which will shut offthe heating elements in the case ofoverheating. This could be caused iflarge articles cover the heatingelements or if the filters in the washcabinet are blocked.

^ Remove the cause of overheating.

^ Remove the service panel.

^ Press the blue "Reset" button on thetemperature limiter.

If this switch trips repeatedly, contactthe Miele Technical ServiceDepartment.
