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.
He unit must be always earthed, also with a non-
metallic delivery pipework.
ATTENTION: in the case of water containing
chloride (or salt water), the earthing (grounding)
conductor is useful also to reduce the risk of
galvanic corrosion due to electrolytic action,
especially with non-metallic delivery pipe and
safety rope.
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 type A 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.
The motor will stop if overheating is detected by means
of thermal protector.
When the windings cool down (after 2 to 4 minutes),
the thermal protector enables re-starting.
The pumps are supplied with 3G1 power supply cable
DRINCABLE type.
ATTENTION The cable modification is forbidden.
7. Operating modes
The system is set to minimize pressure fluctuations
and minimize the number of starts.
WARNING The installation of a small tank (8 ltrs
minimum) on the pump delivery side is always required.
7.5.1. High number of starts/hour
Disconnect the power supply wait 10s and restore
power.
If the pump starts more than 240 times within 2 hours,
it stops.
7.5.2. Dry-run settings operation and manage-
ment
In normal operation conditions, i.e. after the first
starting (30s), the warning Error is displayed so the
pump will try to start again every 10 minutes for 10
seconds for maximum 6 times.
In the case that all these attempts fail. Disconnect the
power supply wait 10s and restore power.
7.5.3. Forced start
To avoid any mechanical blocks, if the pump is in
stand-by state for more than 24 hours, the pump starts
running for a minimum time defined (30 s), and then
until the stop pressure.
8. STARTUP AND OPERATION
8.1. Preliminary checks before start-up of the
pump
Do not start-up the device in case of damaged parts.
8.2. First starting
OFF
Never start the pump before it has been immersed to
a depth of at least 100 mm.
Pump is equipped with a vent plug.
To prime the pump properly, at first start the minimum
immersion depth must be at least 1 meter.
An air vent valve must be used in systems with an
immersed delivery outlet (par. 14 fig. 3).
Do not start the pump with a completely closed shutoff
gate valve.
Never take the pump out of the water while the pump
is still operating.
8.3. Vessel pressure
Tank preloaded pressure must to 0,2 bar lower than
re-start pressure (i.e. 1,6 bar re-start pressure, tanks
to be preloaded at 1,4 bar).
8.4. Abnormal operation
Prolonged operation without a change of water in the
pump causes dangerous increases of temperature and
pressure.
Prolunged operation with a closed delivery port
causes breakage or damage to parts of the pump.
When the water is overheated due to prolonged
operation with a closed port, stop the pump before
opening the gate valve.
Do not touch the fluid when its temperature is
higher than 60 °C.
Do not touch the pump when the surface
temperature is higher than 80 °C.
Wait until the water has cooled inside the pump before
starting again or opening the draining and filling plugs.
8.5. Switch off of the pump
ON
The appliance must be switch off every time
there are faults. (see troubleshooting).
The product is designed for continuous operation,
only by disconnetting the supply cable the switching
off occurs. (see paragraph “6.5 Electrical connection”).
9. MAINTENANCE
Before any operations it's necessary to disconnect the
power supply.
If required ask to an electrician or to an expert
technician.
Every maintenance operations, cleaning or
reparation executed with the electrical system
under voltage, it could cause serious injuries
to people.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid
a hazard.
In case of extraordinary maintenance, or maintenance
operations that require part-removing, the operator
must be a qualified technician able to read schemes
and drawings.
It is suggest to register all maintenance operation
executed.
i
During maintenance keep particular attention in
order to avoid the introduction of small external
parts, that could compromise the device safety.
