ATTENTION: the pump is equipped with a integrated
non-return valve into the pump suction, in order to
fill the suction pipe it is necessary to prepare a filling
system on the suction pipe (par. 14 fig. 4).
Follow local specifications if increasing network
pressure.
EN
Install a strainer 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.
With a geodetic head at outlet 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
Electrical connection must be carried out only
by a qualified electrician in accordance with
local regulations.
Follow all safety standards.
Make sure the frequency and mains voltage correspond
with the name plate data.
For use in swimming pools (not when persons are in
the pool), garden ponds and similar places, a 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 incorporated thermal
protector and with 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 feed the pump with a
frequency converter.

7.3. Programming parameters
To show the programming parameters, select
(menu).
Will be displayed progressively:
UP – User settings: these are the basis settings
that the user may change.
AP - Advanced settings: these settings are available
only to qualified personnel. To enter password is
required (see paragraph 7.6.).
Err - Last 5 alarms. In case of no error, it appears nOnE
AE - You can identify the firmware between the AE
menu. Firmware=AE01+AE02+AE03

7.5. Operating modes

The operating mode allows you to keep the system
Pressure constant at a setpoint value adjustable
with UP01 parameter. The restart pressure can be
calculated subtracting UP01 – UP02, the latter defined
as pressure hysteresis. The product is equipped with a
membrane that works as an expansion vessel.
7.5.1. Warning for high number of starts/hour
The TANK symbol
for high number of starts and stops, if the pump
achieves at least 20 starts in a short time (cycle time
less than 5 seconds).
Press (enter) button to reset the warning.
If the pump starts more than 90 times in 1 hours, Er05
will be displayed.
7.5.2. Dry-run settings operation and manage-
ment
In case of pump not primed and without water inside
the pump casing:
UP03=0 (default)
In normal operation conditions, i.e. after the first
starting (15s), the warning Er01 is displayed so the
pump will try to start again every 10 minutes for 5
seconds for maximum 5 times.
In the case that all these attempts fail, Er01 is kept
displayed and a manual reset or turn off and back on
the pump is required.
