WASHING PROGRAMS - DESCRIPTION
The default ‘original’ programs are installed in program positions 1 to 20. These programs have been researched and
formulated so as to guarantee the best possible washing and disinfecting results. However, they can be changed in
relation to the quantity of detergent.
The remaining 10 positions from 21 to 30 are empty and can be used by the customer to create his own programs.
These new programs can either be created in the manual mode by means of the keyboard, or by using the
“WDTRACE” software (which can be purchased as an optional).
It is always possible to reinstall the original programs by loading them (consult the relative section).
10.1
WASHING AND DISINFECTING PROGRAMS FOR OPERATING THEATERS
The annex “
Program Table
” document describes the functions accomplished by the 20 Operating Theater default
programs.
Only peristaltic pumps P1 and P2 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.
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 (chamber prewash), empty chamber, 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 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
