GW3060 – GW4090
GW3060 series: glassware washers, 60cm, without drying system.
GW4090 series: glassware washers, 90cm, with forced-air drying system and side cabinet to take detergent cans.

Demi: demineralised water, the type of water used in a specific phase of the program.
Cold: cold mains water, the type of water used in a specific phase of the program.
Hot: hot mains water, the type of water used in a specific phase of the program.
N.C.: "NOT CONTROLLED" - refers to the relatively short heating phases during which the heating elements are “on” but no target temperature value is set.
P1, ... P5: the code refers to the activation of the relative peristaltic pump, with dispensing of the liquid detergent associated to it.
Each pump has a default dispensing rate set in the factory.
P1b, P2a: the code refers to dispensing by pump P1, P2 at a rate different from the default rate, used in special cases, as specified in the program table.
DEFAULT DOSAGE LABORATORY PROGRAMS GLASSWARE WASHER GW [ml/litro]
TD: thermal disinfection - phase during which the target temperature is kept above a target value for a specified time. The efficacy of the thermal disinfection process is indicated by
means of parameter A0. In preset programs, the target value for a thermal disinfection process is always at least 80°C.
Temp. T [°C]: Target temperature of the current phase. The temperature inside the tank is kept constant around the specified value for the time shown in the table. The phase during
which the temperature is held at the target value is called the EXTENSION phase. When no target temperature is indicated or the indication is (“0”), the heating elements are not
activated (e.g. during a cold prewash or for cold rinses).

WARNING
This document is an appendix to the appliance's user manual and must be consulted together with the manual for proper, safe use of the device.
It contains up-to-date information concerning the characteristics of the washing programs installed in the appliance.
Programs may vary depending on the firmware version installed in the appliance. If in doubt, have authorised staff check on the appliance that the installed version is the same as the
version stated in the table at the back of this document.

VARIOUS NOTES
WATER FILLING: at each step corresponds a load equal to 10 liters of water.
PHASE NUMBERING: 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 TIME: the stated time for the complete cycle refers to standard test conditions: intake water pressure 3bar, cold water temperature 25°C, electrical connection 3/N/PE 400V 50Hz).
Pressures and temperatures lower impact on cycle duration. The cycle times indicated are approximate and refer to the washing cycle only, without considering the drying phase.
PARAMETER A0
Parameter A0 is used by product standard UNI EN ISO 15883-1 to assign a numerical value to the thermal disinfection process.
It is calculated mathematically using the formula:
z = 10°C - t = duration of time interval considered in seconds - T = load temperature in °C.
When calculating the parameter, only the time intervals during which the temperature is above 65°C are considered.
For our thermal disinfection programs, the calculation is simplified by only including the “extension” phase, when the temperature is kept constant with reference to the target value set.
DRYING: Drying stage at the end of the cycle are present only on the models equipped with a drying system.
