suction hose, in order to avoid the hose narrowing due
to suction vacuum.
With the liquid level on the suction side above the
pump (inflow under positive suction head, par. 14. fig.
1) fit an inlet gate valve.
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.
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 (parameter UP02) is 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 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 capacitor
and thermal protector, 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 (after 2 to 4 minutes), 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.
