START-UP PROCEDURES
Following installation and checking of all electri-
cal and hydraulic connections, the unit may be
turned ON by pressing the green switch posi-
tioned below the control panel.
The display will automatically position a triangu-
lar cursor at the indicator for electric current.
Simultaneously, the relative values of the afore-
mentioned parameters will be displayed.
When humidification is requested, the LED 7)
HUMIDIFY ON is turned ON and the control unit
fills the cylinder with water: the fill led (4) is also
turned on at this point. The operation proceeds
until the correct current value is reached. This
value dependes not only on the steam produc-
tion imposed but on the conductivity of the feed
water measured by the two small electrodes
positioned on the filling cup as well.
Steam production is factory-set at 70% of maxi-
mum production capacity.
START-UP WITH CONDUCTIVITY OF FEED
WATER SUPERIOR TO 1000 MICROSIEMENS
The humidifier reaches full efficiency immediate-
ly, adjusting water flow to the cylinder to provide
the value of current necessary to produce the
required steam quantity.
START-UP WITH CONDUCTIVITY OF FEED
WATER INFERIOR TO 1000 MICROSIEMENS
The humidifier reaches full efficiency slowly
because it begins on “soft” cycle. This cycle
may last one hour dependent upon the conduc-
tivity; it will proceed until the conductivity reach-
es the projected value. If the scarcely con-
ductible water reaches the top level electrodes
during the filling phase a prealar m (E05)
appears. It is followed by another prealarm
(E02) signalling reduced functionality if the con-
ductibility remains low during successive fill-
ings.
This pre-alarm may persist for a prolonged time
period in cases where conductivity is very low.
The aforementioned pre-alarms do not block the
functioning of the unit and they are turned off
automatically as soon as the conductivity within
the cylinder reaches projected values.
If the situation persist after numerous fillings
(particularly when the humidifier has been in
use for some time) it means that the cylinder
needs cleaning or replacement and on addition-
al alarm (E08) will appear blocking the function-
ing of the unit.
SETTING OF PARAMETERS
As already mentioned, some of the indicators
are only displayed values while others may be
modified by the user:
2) maximum steam production
3) drainage with electrodes whether under cur-
rent or not.
Respositioning of the triangular cursor by using
the pushbutton 12) SEL, the indicators are dis-
played in a clockwise manner in the following
order:
1) - 2) -3) - 4) - 5) - 1)
visualisation lasts for 30 seconds afterwich the
display returns automatically to the initial start
configuration, that is, either current or relative
humidity depending on the model.
In cases of modification of parameters, the
memorization of the new value must be made
within 30 seconds by pressing push-button 12)
SEL.
MAXIMUM STEAM PRODUCTION
Using push-button 12) SEL, position the cursor
at the indicator for max production. The value of
maximum steam production which had been
previously set is visualized and with pushbutton
13) and 14) this value may be either increased
or decreased.
Pressing pushbutton SEL a second time the
new value is memorized and the cursor is posi-
tioned at the indicator 3) CONFIGURATION.

POWER
In “AUT” position the system supplies 30% of
max water vapour delivery which is preset in
phases Iª and IIª of LevControl 1; Iª, IIª, IIIª of
LevControl 2. It supplies the max. water vapour
delivery in phase IIIª of LevControl 1 and in
phase IVª of LevControl 2.
In “MAX” position it always supplied the max.
water vapour delivery.
Note: The “MAX” position must be used only
during the manual leavening phase.
