UNIT OPERATION
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
model and the microprocessor software version.
At the end of the self-test the display show:
−
The quantity of the last discharge.
−
Internal temperature.
Set desired water quantity using
[+]
and
[-]
keys. Setting appears on display (13).
Increases/decreases may be obtained in three different ways:
step by step: pressing once
[+]
and
[-]
keys
continuous: keeping constant pressure on
[+]
and
[-]
keys
fast: 3 seconds after keeping constant pressure on
[+]
and
[-]
keys.
Press
[START]
key to execute the batch.
Water delivery may be stopped at any time by pressing
[STOP/C]
key. Quantity of water
delivered will then flash on display (13).
To resume delivery of remaining water press
[START]
key.
Press
[STOP/C]
key and the original litre setting will reappears on display. Press
[STOP/C]

Quantity in memory is retained at the end of each dosing. Simply press
[START]
key if
identical successive dosing is desired. Memory is protected against power failure; pre-set
dosing can be resumed pressing
[START]
key when power is restored. In this case the
display shows the message “

”. At the first pressure of the
[STOP/C]
key the machine
shows the discharged quantity till it was stopped, the operator may now cancel the
discharge by pressing again the
[STOP/C]
key, or to resume by pressing
[START]
.
Water temperature is selected by turning the temperature regulation knob: the
temperature is shown on the electronic thermometer display. When regulating the water
temperature wait a few seconds between adjustments so as to allow the temperature to
stabilize.
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 5°C
lower.
ATTENTION: the graduated scales are indicative. They suffer from the temperature of the
water input. The scale "red" indicates the temperature of the mixed output when you use
HOT. The scale "blue" indicates the temperature of the mixed output when you
use NETWORK.
Low temperatures (below 10 ÷ 15°C) may be obtained only when using a refrigerator.
The scales have been obtained with temperatures of 3° C (refrigerated), 18° C (net) and
65° C (warm).
