Switch on the doser-mixer using the external switch (or by plugging in the flying socket).

The first displays appearing at the switching on refer to the self-test. The displays show the numbers form

0 to 9, the microprocessor software version, then the data regarding the last discharge.

•

Press P00 on the keyboard (the yellow Manual led lights up and the decimal point of the litres

flashes), then select the required water quantity. If only the quantity has to be stored, press START. If

the operator needs to store also the temperature, press the key

point of the temperature, which can be set. In case of error, in the litres or in the temperature, press

STOP/C key and reselect.

•

Press the START key: the display 8 shows the actual discharge temperature and the display (16)

indicates the decreasing litres.

•

To manually stop delivery at any time press the STOP/C key. In the display (16) the quantity if

delivered water flashes; to resume the dosage, press again the START key; otherwise pressing again

the STOP/C key the memory is cancelled and a different quantity can be set.

•

Adjust the water temperature using the knob (5), checking it on the electronic thermometer (8). In case

of correction, wait a few seconds before intervening, so as to allow the temperature to stabilize.

•

To obtain the same water dosage in successive operations, simply press the START key, as the doser-

mixer is provided with a memory. In the case of power failure during dosing the data are not lost;

when power is restored simply repress the START key to complete the dosing operation (see page 20

par.3.5.3).

•

To modify quantity and/or temperature in memory, press directly the

first data entry.

•

To ensure optimum operation the warm water temperature must be at least 10°C higher than the

required delivery water temperature and the cold water should be at least 3°C lower. Low

temperatures (under 10° - 15°C) may be obtained only using a refrigerator.

•

The doser-mixer is equipped with a valve for manual delivery of pre-mixed water (by-pass). This

valve can be used both for discharging possible backwater in the pipes, when the doser is switched on

for the first time every day, and for water delivery during power failure or in the event of dosing

solenoid valve failure.

NOTES:

1) The by-pass function light never switches on in this machine version, and the RUN

function light is on during the whole discharge.

2) The stored temperature appears only when a recipe is recalled, or when the key for the

quick modification is pressed, and remains for 6"; then the

actual internal probe temperature.
