These operations are exclusively intended for qualified staff.
From the OUT OF SERVICE status, you can manually start the electric pump, for TESTING and PRIMING.
• Press the set of keys  and  for 5 seconds (all the LEDs flash to indicate the STEADYPRES is ready to start in manual
mode)
• Press the ON/OFF button
• The pump starts at minimum speed.
• On the control panel, the LEDs assume the status in continuous rotation and the status LED is fixed green.
To read the PRESSURE
• Press the key  to display the working pressure.
• The status LED turns GREEN.
• Press the keys  or  to increase or decrease the WORKING PRESSURE (steps of 0.5 bar).
To read the CURRENT
• Simultaneously press the keys  and  for 1 second.
• The status LED turns RED.
• Press the keys  or  to increase or decrease the CURRENT (steps of 0.5 A).
To read the FREQUENCY or PRIME the pump
• Simultaneously press the keys  and  for 1 second.
• The status LED turns BLUE.
• Press the keys  or  to increase or decrease the FREQUENCY (steps of 5 Hz. The first LED has a value of 30 Hz).
• To prime the pump, increase the frequency up to 50 Hz to have the maximum priming capacity.
• If priming does not take place approximately within 4 minutes, the procedure interrupts and all the hydraulic and mecha-
nical checks should be carried out in this case.
EXAMPLE
Pressure = 3.5 bar
GREEN status led
1 LED fixed = 1 bar
1 LED flashing = 0.5 bar

1 LED flashing = 0.5 A
Current = 4.5 A
RED status led
1 LED fixed = 1 A
Frequency = 40 Hz
BLUE status led
LED 1 fixed = 30 Hz
Subsequent LEDs fixed = 5 Hz
