 START-UP:
WARNING: do not allow the pump to run for long without water the first time it is switched on otherwise the inverter will
overheat! Prime the pump before switching on the system.
Once all the electrical connections have been made and checked to ensure they are correct, close the unit's cover and switch on the power.
On initial start-up the operator will be requested to enter the current as stated on the motor data plate on the following screen:
Imax
0.5 Amp
The Sirio is now in stand-by; in this mode (pump stationary) all the various parameters can be set (see "programming" paragraph) before the
system is started up.
To start up the pump, simply press the "on-off" button in the centre: The Sirio will exit the stand-by mode and the motor will start turning.
If the pump does not run or if it produces anomalous vibrations, ensure correct connection of the pump and of its capacitor in case of single-
phase pumps. For three-phase pumps also check the direction of rotation is correct.
To facilitate pump filling, the "+" button on the main screen can be pressed to force the pump up to top speed without the dry running
protection feature cutting in.
After setting all the device parameters, write the data entered in the form found at the end of this handbook for future reference and
for guarantee purposes.
 PROGRAMMING
DESCRIPTION OF THE BUTTONS
Left-hand arrow: this scrolls back through the menu pages
Right-hand arrow: this scrolls forwards through the menu pages
On-Off/Reset: this switches the device from stand-by to operation mode and resets the unit in the event
of alarms and/or errors.
"+" button: this increases the value of the parameter currently shown on the display, it allows the pump to run at
top speed without the dry running protection feature cutting in.
"-" button: this decreases the value of the parameter currently shown on the display.
MAIN MANU STRUCTURE
The main menu shows the operational values of the system: pressure, current frequency of the motor, input voltage, output current of the
motor and internal temperature of the inverter. It is also possible to select the language.

Set the value as stated in the technical specifications of the pump (in the case
of 3-phase pumps, identify the value for 230V delta connections); press the
central key to confirm and proceed with entry of the maximum operating
pressure(Pmax)
After setting the pressure, press the central key again to exit the settings menu.
