• The noise (continuous equivalent in dbA) of
the motor-driven pumps is less or equal (≤) to
70 dbA.
• The voltage (230 Volts alternating current)
indicated on the pump rating plate must correspond
to the available mains voltage.
• The temperature of the liquid conveyed must not
exceed 35°C.
• Never attempt to lift or move the pump by stretching
the power-supply cable whilst it is plugged into the
mains.
• Make sure that the plugged electrical connections are
in an area safe from flooding and are protected from
humidity.
1. Safety Measures
• Read carefully the operating instructions before
assembling and starting. The appliance must not be
used by operators who are not thoroughly acquainted
with the instructions handbook (operating instructions).
Moreover, the appliance must not be used by persons
under the age of 16.
• The user is liable towards third parties in the area where
the appliance is in operation.
• Before starting it is necessary to check that the
necessary electrical protection measures are met, by
means of a test carried out by a specialist.
WHILST using the pump, there should be
no person in the water or liquid to be
pumped, and the carrying out of any type
of maintenance is strictly forbidden.
The pump may be connected only by means of a
safety switch for fault currents, with an opening
rated current up to 30 mA and a socket with an
earth contact in compliance with the regulations.
Protection: at least 10 Amps.
Operation in swimming pools and garden ponds is
not recommended.
For other operation, the provisions in conformity with
the standard VDE 0100 part 702 must be respected.
CAUTION: Before checking, unplug the pump
from the mains!
Replacing the power supply cable requires using
special tools and therefore you must address to the
authorized after-sales service.
The pump may only operate with an extension
obtained through cable mod. H07 RNF and a thread
section of no less than 1 mm in compliance with the
DIN 57282 or DIN 57245 standard.
ELECTRIC SELF-PRIMING JET PUMP

• Before use it is necessary to check that the plug and
the mains connection line are not damaged.
• Unplug from the mains before performing any work on
the pump.
• Avoid directly exposing the pump to the jet of water.
• The user is responsible for complying with the local
regulations concerning assembly and safety.
• The user by taking appropriate measures (e.g. installing
an alarm, reserve pump and the like) will have to
exclude the possibility of indirect damage caused by
flooding premises due to failure of the pump.
• In the event of the pump failing, repair work may only
be carried out by the repair workshops of the technical
service. Only genuine spare parts must be used.
• It is notified that in conformity with the law on product
liability
we cannot be held responsible
for the damage caused by our appliance:
a) because of improper repairs not carried out by the
personnel of the assistance points authorized by us; or
b) if GENUINE SPARE PARTS are not used to replace
parts; or
c) if the indications and provisions given in the instructions
handbook are not complied with.
The same provisions hold for the accessories.
Resistance
This pump should not be used to convey inflammable,
combustible or explosive liquids.
2. Use
CAUTION! Sector of use
• For irrigation and watering of lawns, gardens,
vegetable patches, etc.
• For operating garden sprinkler systems
• For drawing water from ponds, streams, water butts
and wells, subject to fitting of suitable filter.
Acceptable liquids
In order to pump clear water (fresh water), rainwater
or non-aggressive chemical cleaning solutions.
Abrasive liquids or any other type of corrosive
liquid could damage or destroy the pump.
Operating Instructions
Generally speaking it is recommended to use a
preliminary filter and exhauster with a suction
hose, suitable and foot valve (reflux lock) to avoid
long suction times and pointlessly damaging the
pump due to stones and solid foreign bodies.
3. Before Starting
Your irrigation pump is self-priming. Before starting for
the first time, the pump has to be filled through the
delivery union with the delivery liquid until it overflows.
Suction Piping
• Fit the water suction pipe so that it points upwards
towards the pump. Absolutely avoid fitting the suction
pipe higher than the pump (formation of air bubbles in
the suction pipe).
• The suction and delivery piping must be fitted so as
not to be able to apply any mechanical pressure on
the pump.
• The suction valve should be situated at least 30 cm.
below the bottom water level.
• Suction pipes that are not airtight suck in air obstructing
suction of the water.
Delivery Piping
During suction, the cut-off parts (sprayers, valves, etc.)
situated in the delivery piping have to be fully open so
that the air in the suction pipe can be freely expelled.
4. Maintenance Instructions
The irrigation pump is entirely maintenance-free.
Should the pump become blocked, first try rinsing. Should
it turn out that the blockage is due to the inefficiency or
complete absence of the filters, dismantle the hydraulic
section and thoroughly rinse the interior, carefully
reassemble and refit the filters correctly before turning
back on.
• If there is a risk of frost, the pump has to be emptied
completely.
• When the pump is not going to be used for a long time,
for instance in the winter period, it is recommended
to rinse out the pump thoroughly with water, empty it
completely and store it in a dry place.
• Before restarting, check whether the pump works freely
by briefly connecting and disconnecting it.
• Then fill the pump again with the delivery liquid and
set it up for use.
CAUTION!
In order to work, the pump must always be filled
with the delivery liquid until it overflows!
Caution: The pump must never run dry. The
manufacturer’s warranty is null and void in the
event of damage to the pump caused by its running
dry.
Check that the pump is airtight, in fact not airtight
pipes draw in air preventing the pump from
working properly.
If it is not possibile to eliminate the trouble, please call our service department.
To avoid damage during transport, please ship in the ORIGINAL PACKING.
