WASHING AND DISINFECTING PROGRAMS
The functions accomplished by the 20 default programs are described in chapter 6.3 on pages 33,34 and 35.
Only peristaltic pumps 1 and 2 are activated in the standard programs. To activate the other pumps, access the
programming menu and activate them in the required phase.
A drying phase for the material can be added to the washing program (see Drying Programs section).
NOT APPLICABLE FOR THE GW3060 MODELS.
Warning
To prevent possible contamination amongst the various cycles due to water residues that may have remained
after a program, it is advisable to run program N° 1 (tub prewash) at the beginning of a work day as a preventive
safety measure.
A washing program generally comprises phases of different types:
• Prewash with mains or demineralized water
dilutes or softens the pollutants on the instruments; Use cold water without additives to eliminate coarse
dirt and foam substances.
• Hot alkaline wash
effective action that detaches the pollutants from the walls and solubilizes them; this phase is usually
performed at temperatures between 40°C and 65°C for a few minutes. Alkaline or neutral detergents are
used.
• Neutralizing in an acid environment
action that eliminates alkaline residues
solubilization of the calcium carbonate precipitates from the surfaces of the instruments
prevents the surfaces from becoming opaque
• Rinsing with mains water
dilution of the previously used chemical additives
every rinse dilutes the initial concentration of the pollutant by about 99%
•
Rinsing in demineralized water
dilutes the inorganic salts and any organic fractions in the mains water
•
Thermal disinfection
Thermal disinfection is a hot alkaline washing phase where the washing temperature exceeds 70°C and is
maintained for a period of time that depends on the required thermal disinfection action.
Consult the next section for details about the thermal disinfection process.
•
Drying phase
Final process phase that must guarantee sufficient drying
