ATTENTION: the pump is equipped with non-return
valve built into the pump suction, in order to fill the
suction pipe there must be a filling system on the
suction pipe (chap. 14 fig. 4).
Follow local specifications if increasing network
pressure.
EN
Install a filter on the suction side of the pump to
prevent foreign particles from entering the pump.
6.4.3. Delivery pipe
Fit a gate valve in the delivery pipe to adjust delivery
and head.
when the geodetic difference in level in the delivery
section is over 15 m fit a check valve between the
pump and the gate valve in order to protect the pump
from water hammering.
ATTENTION It is necessary to check that the restart
pressure (subtraction between
compatible with the actual pressure of the pump and
of the water column of the system.
6.5. Electrical connection
OFF
The electrical connection must be carried out
only by a qualified electrician in accordance
with local regulations.
Follow all safety standards.
Make sure that the frequency and mains voltage
correspond to the values indicated on the plate.
For use in swimming pools (only when there are no
people in the pool), garden ponds and similar places,
an F-type residual current device with IΔN not
exceeding 30 mA must be installed in the supply circuit.
Install a device for disconnection from the mains
(switch) with a contact separation of at least 3 mm in
all poles.
The pumps are supplied with with a built-in thermal
protector and with a plug.
Connect the plug to a socket with an earth lead.
The motor will stop if overheating is detected.
When the windings cool down, the thermal protector
enables re-starting.
The pumps are supplied with power supply type
H07RN-F with plug and cable section equal to or greater
than the value defined in table 1 in paragraph 14.2.
When extension cables are used, make sure the cable
wires are of adequate size to avoid voltage drops.
6.5.1. Operation with frequency converter
ATTENTION: never power the pump with a
frequency converter.

7.3. Programming parameters
To view the programming parameters, select
(menu).
The following are displayed in succession:
UP – User settings: these are the basic settings
that the user may change.
AP - Advanced settings: these settings are available
only to qualified personnel. To enter, a password is
required (see paragraph 7.6.).
GP – booster unit settings: to be set only if there is a
booster unit.
Err - Last 5 alarms. In case of no error, nOnE appears.
AE - By means of the AE menu, you can identify the
firmware installed. Firmware=AE01+AE02+AE03

7.4.4. Booster set with random starts
To activate the mode booster set with random starts
(which consists of the single pump behavior with the
addition of a random delay both when the pump is
turned on and off) follow the procedure.
1.
1.1 Turn on the pump and set it to STOP
1.2 Access the GP menu
1.3 Set GP01=1
The settings of the stop pressure and restart pressure
remain enabled by parameters UP01 and UP02 as for
normal single pump mode.
For correct booster set mode operation UP01 must be
the same for both pumps, also UP02 must be the same
for both pumps.
