– TABLE OF PROGRAMS –
ATTENTION
This document is complementary to the user manual of the equipment and must be used in conjunction with the manual for the correct and safe use of the device.
The laboratory programs are installed on the "GW" machines.
The programs may vary depending on the firmware version installed. Check on the machine the correspondence between the installed version and this version, as shown in the table at
the bottom of the document.
ABBREVIATIONS USED
P1, ..., P5: the acronym refers to the activation of the corresponding peristaltic pump. Each pump doses the default preset values.
Depending on the machine model you choose, some peristaltic pumps can be absent.
P5 pump is always optional.
N.C.: "NOT CONTROLLED" - refers to the stages of heating, relatively short, in which the heaters are turned on but it is not set a target value of temperature to be reached.
TD: Thermal disinfection.
INT: intense
INS: Instruments
AGG: aggressive
ENC: very dirty
Cold, Hot, Demi: cold, hot, demineralised water, the type of water used in a specific phase of the program.

NOTES
WATER FILLING: at each step corresponds a load equal to 40 liters of water.
NUMBER OF THE PHASES: the display of the machine, during the progression of the cycle, provides information on the various stages in progress. The first phase assumes the identity of
"Phase 0", the second phase "Phase 1", etc..
CYCLE DURATION: The given duration is indicative and refers to standardized test conditions (inlet water pressure: 3 bar, cold water temperature 25 °C, electrical connection 3/N/PE 400V
50Hz). Pressures and temperatures lower impact on cycle duration. The total time reported is indicative, it can vary significantly depending on the inlet water pressure, of the total weight
of the load and of the oscillations of the mains voltage power supply.
DRYING: Drying stage at the end of the cycle are present only on the models equipped with a drying system, “DS” models.
A0 PARAMETER
A0 parameter is used by the international standard UNI EN ISO 15883-1 in order to associate a numerical value to the disinfection performed.
z = 10°C - t = time in seconds - T = temperature °C.
For the calculation of the parameter, the 15883 standard considers only the intervals at which the temperature is greater than 65 °C.
For thermal disinfection programs the calculation is simplified by counting only the "extension" phase, where the temperature is kept constantly around the target value set.
The drying phase meets the requirements of the standard when the following minimum requirements are met.
Greater values in the extension time and / or temperature are to be considered as improvements.
Times and temperatures lower than those listed here do not guarantee the compliance of the drying phase to the regulatory requirements (ref. par. 6.12 standard 15883-1).
Drying parameters, Time and temperature
Thermodisinfections at 90°C or 93°C
Thermodisinfection at 80°C
The values refer to a dry test load of 30kg properly positioned, with no overlapping of instruments (ref. M12x100 stainless hex head screws, see Section 6.3.2.2 EN ISO 15883-2).
The drying is only available on "DS" models (eg. WD6090DS).
The total cycle time shown is indicative, can vary significantly depending on the incoming water pressure, the total weight of the load and fluctuations in the mains voltage. The times
refer to the conditions listed in the operating instruction manual, empty chamber.
