GENERAL
Read the instructions carefully before installing this unit. Verify the technical characteristics of the motor in
order to assure the compatibility with the device.
DESCRIPTION
EPR - Electronic Pressure Regulator
The EPR is an electronic controller for single-phase pumps up to 2.2kW with an innovative system of pressure
reduction/regulation in order to maintain a steady outlet pressure. Therefore, in addition to the typical
features of traditional electronic pump controllers: integrated non-return valve, flow sensor, accumulation
membrane, pressure gauge, indicator led-lights, dry-run protection, automatic restart system (ART). It allows
adjusting and control of the output pressure, avoiding overloads and water hammer. Ultimately, improving
the comfort and durability of the installation.
DPR - Digital Pressure Regulator
Evolving from EPR, adding to its features a digital display with instantaneous indication of current
consumption and outlet pressure since it houses current and pressure transducers inside. This device allows
separates the regulation of the outlet pressure from the cut-in pressure to improve the flexibility of the
system’s hydraulic reserve, reducing the prolongation of inactive pauses and, consequently, reducing the
number of starts of the electric pump. This independence from pressure regulation also allows operation with
a minimum dierential between the cut-in pressure (ON) and the outlet pressure (OUT). It also integrates
alarm and function registers, as well as the possibility of adjusting multiple operating parameters such as
automatic reset system, anti-flood function, start and stop delays, etc.

*ART FUNCTION (AUTOMATIC RESET TEST)
When the device has stopped, the pump by the intervention of the dry-running protection system, the ART
tries after 5 minutes to re-start the pump in order to restore the water supply. After this first attempt is
performed, it will attempt every 30 minutes.
In the DPR, this function can be activated in the ADVANCED MENU. The number of attempts can be set
(1-48) and also the span of the attempt (10-40 seconds).
**APR FUNCTION (ANTI-BLOCKING PERIODIC ROUTINE)
After 72 hours without operation the pump is automatically started for 10 seconds in order to avoid rotor
locking. In the DPR the display will show the message “APR” while the pump is operating. In the EPR the
pump LED will be on during this operation.

HYDRAULIC INSTALLATION
Before proceeding with hydraulic connection it is essential to prime the pump correctly. The DPR and
EPR must be installed in a vertical position (arrows in upward position), thus connecting the inlet opening
directly to the pump outlet; and the outlet to the network. The following accessories are recommended:
flexible with a disassembling link for network protection, protecting the set from possible flexion charges
and vibrations, ball valve which permits the isolation vales on suction and discharge of pump, use of unions
for easy disconnection of the pump. optional pressure tank for protection against possible water hammer
and vibrations.
ELECTRONIC CONNECTION
The electric connection must be performed by qualified technicians in compliance with the Australian
regulation. Before doing manipulations inside the device, it must be disconnected from the electric supply.
Wrong connection could spoil the electronic circuit.
The manufacturer declines all responsibility in damages caused by wrong connections.
Check if the power supply is between 110-230V.
If you have purchased the unit without cables see diagram below. (EPR and DPR devices have the same
electric wiring diagram.)
• Use cable type H07RN-F 3G1 or 3G1.5 with section enough to the power installed.
• Do the pump connection U, V and .
• Do the power supply connection L, N and .
• The earth conductor must be longer than the others. It will be the first one to be mounted during the
assembly and the last one to be disconnected during the dismantling.
The earth conductors connections are compulsory!

STARTUP
Before starting the device please read the previous sections, especially “Hydraulic Installation” and
“Electrical 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 motors rated current:
• Press and hold for 3 seconds.
• The current intensity value is displayed on screen and LED A is flashing (factory setting 16A).
• By pressing of and it is adjusting the rated current reflected 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 pressing of and it is adjusting 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 outlet pressure and anticlockwise to
decrease it (factory setting 3 bar) . Look at the working pressure viewer (Figure 2) while
turning the screw to have a first approximation of the outlet pressure setting.
• Close the tap and do the final adjustment looking at the pressure gauge (EPR) or the display
(DPR).
• The regulated pressure should be at least 1 bar less than the maximum pressure of the pump.
