OPERATION
The electronic controller orders the automatic start and stop of the
water pump when opening and closing any tap or valve of the ins-
tallation. When the water pump starts, it keeps running while exists
any tap opened in the system, giving a constant flow and pressure
to the network.
CONSTRUCTION CHARACTERISTICS
· Inlet and outlet: male G1".
· Special non return valve which avoids surges.
· Safety system avoiding dry running operation.
· Automatic reset function.
· Pressure gauge (optional).
· Manual start switch (RESET).
· Tension led (POWER).
· Pump-working led (ON).
· Security system led (FAILURE).
HYDRAULIC CONNECTION (FIG.2)
Before proceeding with hydraulic connection it is essential to pri-
me the pump correctly. The device must be installed in a vertical
position, thus connecting the inlet opening (male 1") directly to the
pump outlet; and the outlet (male 1") to the network. The following
accessoires are recommended: flexible with a disassembling link
for network connection, protecting the set from possible flexion
charges and vibrations, ball valve which permits the isolation of
the pump from the installation a tap (A) on the same level as the
device ( FIG.2).
REMARKS
Mod. 2/22: The water column between the pump and the highest
point of use should not exceed 4 m for the Model F10 and the
pump should supply a minimum pressure of 2 bar. For Model F15
the highest point of use should not exceed 10 m and the pump
should supply a minimum pressure of 2,5 bar. In case of using
points until 30 m should be use the model 22 R. The adjustment of
starting pressure is made by a screw placed in the back of the de-
vice (FIG.5). Read the indicated pressure showed in the pressure
gauge when the pump starts and perform on the screw according
to the wished side.
Mod. 3: For the F15 the water column between the pump and the
highest point of use should not exceed 12 m and the pump should
supply a minimum pressure of 2,5 bar. For the model F22 the wa-
ter column should not exceed 20 m and the pump should supply a
minimum pressure of 3,2 bar. Example Compact 2/22:

20 m
This operation only adjusts the starting pressure, not the operating
pressure of the installation, which only depends on the pump fea-
tures. It will be easier to proceed with the adjustment if the tap of
the installation is opened, that will reduce the internal pressure of
the device.
*These heights are between the device and the highest point of
use. To work at more height, mount the device out of the pump at
the desired position.
ELECTRIC CONNECTION (FIG.3 and FIG.4)
Before performing any manipulation inside the device, it must be
disconnected from the mains.
Installation and electrical connections must be carried out by qua-
lified personnel respecting the safety requirements as well as the
regulations in force in each country.
Incorrect connections can damage the electronic circuit. The ma-
nufacturer will not be liable for damage caused by bad con-
nections.
- Check that the line voltage is 230V/115V~1 (depending on mo-
del).
- It is essential to install a high sensitivity differential switch: I=Δn 30
mA (class A or AC). It is essential to use a circuit breaker adjusted
to the motor consumption.
If you have acquisted the uncabled version follow these steps:
1. Remove cover 1 of the electronic circuit and make the connec-
tions according to the scheme visible on diagram 3.
2. Use H07RN-F 3G1 cables up to 3G2.5. The ends connected to
the device must be provided with fork-type terminals, for the appro-
priate cable section and maximum width 7 mm.
3.Connect U, V and earth to the motor.
4.Connect L1, N and earth to the network.
Earth conductor must be longer than the others. It will be the first to
be connected and the last to be disconnected.
Earth conductor connections are mandatory!

The device can also be used for 3-phase or single-phase pumps
with intensities higher than 10 A (model 2/3) and 16 A (model 22),
using an auxiliary contact (minimum contacts capacity of 4 kW, coil
220V). In this case the connections will have to be made according
to scheme in FIG.4.
AUTOMATIC RESET FUNCTION
If the device goes into failure mode, this function will execute a se-
ries of automatic starts to attempt to restore operation without any
manual intervention via the RESET button. The system operates
as follows: The appliance is in failure mode due to water failure,
for example; after 5 minutes in this condition the system will do a
25-second RESET, attempting to prime the pump. If the system is
able to prime the pump, the failure will disappear and the pump will
be ready to operate without any problems. However, if the failure
persists, the system will do another RESET after 30 minutes, and
will continue in this manner systematically every 30 minutes for 24
hours. If the failure still persists after all these attempts, the system
will remain in this condition until the problem has been resolved by
manual intervention.
STARTING
1. Be sure that the pump is correctly primed, then gently open one
tap of the installation.
2. Conect the device to electric supply, the tensionled will lit
(POWER).
3. The pump starts working automatically and within a period of
20-25 seconds the pressure will reach aproximately, the maxi-
mum pressure provided by the pump. During its working the co-
rresponding led (ON) will be on.
4. Close the tap indicated on point 1. After 10-12 seconds, the
pump will stop, The tension led (POWER) will be the only one
to remain on. Any problem after this procedure will be due to a
defective pump priming.
POSSIBLE PROBLEMS
1. PUMP DOES NOT STOP:
A) Water leak higher than 1 l/min. at some point: check that all the
used taps are closed.
B) Breakdown on the electronic card: proceed to its substitution.
C) Incorrect electric connection: verify the connections according
to FIG.3.
2. PUMP DOES NOT START:
A) The pump is not primed; the protection against dry running
operation has stepped in and the FAILURE led is on: prime the
water pipe, drain the system water by opening tap (A) on the
same level as the device to decrease the pressure of the water
column over it (FIG.2), and check by pressing the manual start
button (RESET).
B) Pump is blocked: led (FAILURE) is on, the security system is
activated. When we act on the manual start switch (RESET) the
led (ON) is activated but the pump does not work: contact with
your dealer.
C) Failure in the electronic circuit: switch off the pump from the
power supply, wait a few seconds and turn it on again, the pump
should start, if it does not start then replace the electronic circuit.
D) Not electrical supply: check the proper electric feeding. The
tension led (POWER) should be on.
E) Not enough pump pressure: the security system has been ac-
tivated and the corresponding led (FAILURE) is on. Check that
the pump pressure was at least 1 bar higher than the starting
pressure for the model F, and for the model R follow the table in
HYDRAULIC CONNECTION.
F) Air in the pump aspiration: Pressure lower than the nominal or
constants oscillations. The security system will act by stopping
the pump, the LED (FAILURE) will be on. Check the sealing of the
connections and the O-ring of the aspiration conduct.
3. PUMP STARTS AND STOPS REPEATEDLY:
Small leak in some point of the installation: Verify possible taps or
WC tank leaks and repair them.
INSTALLATION OF THE PRESSURE GAUGE-OPTIONAL
(FIG.1)
The pressure gauge has an O-ring and two fixing screws. The pres-
sure gauge must be mounted in the side with the three holes, one
big central hole and two more little for fixing the gauge by means of
the two supplied screws. Previously you should remove the screw
located in the central hole and then introduce the cylindrical con-
nector of the pressure gauge. Then fix the pressure gauge with the
two screws supplied with it.
