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
LED A is flashing (factory setting 16A).
- 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
START is flashing.
- By mean of
and
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)
while turning the screw to have a fisrt aproximation of
the outlet pressure setting.
- Close the tap and do the final adjustment looking at the
manometer (EPR) or the display (DPR).

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 specified on the nameplate of the pump. If a
new pump is installed this process should be repea-
ted.
