STARTUP
Before starting the device please read the previous
sections, especially “Hydraulic Installation” and “Elec-
trical connection”.
Follow next steps:
1. Start the device. Connect to the power supply and press
ENTER in the DPR model. Connect to the power supply
in the EPR model.
2. (Only DPR)
Set the pump rated current intensity value:
- Press during 3 seconds.
- The current intensity value is displayed on screen and
-
By mean of and -
ted in the characteristics plate of the motor. See Note 1.
- Press for validation.
3. (Only DPR)
Set the cut-in (start) pressure:
- Press during 3 seconds.
- The start pressure value is displayed on screen and LED
- By mean of and is adjusted the start pressure
from 0,5 to 5,5 bar.
- Press for validation.
4. Set the maximum pressure of the installation:
- Open a tap.
- Take the provided allen key.
- Turn the regulation screw clockwise to increase the out-
let pressure and anticlockwise to decrease it (factory set-
ting 3 bar). Look at the working pressure viewer (Fig. D)
the outlet pressure setting.
manometer (EPR) or the display (DPR).
- The regulated pressure should be at least 1bar less than
the maximum pressure of the pump.

5. The unit EPR is ready to operate but the unit DPR has
more optional adjustments that can be set through basic
and advanced MENUS. See the next chapter.
Note 1: it is important to introduce exactly the rated
current specied on the nameplate of the pump. If a
new pump is installed this process should be repea-
ted.
