1. Safety measures

Carefully read the operating instructions before assembling
and starting. The appliance must not be used by persons
who are not thoroughly acquainted with the instructions
handbook (operating instructions). Children and persons
under the age of 16 cannot use the pump and must be
kept well away from the appliance when it is connected.
The user is liable towards third parties in the area where
the appliance is in operation.

While the pump is operating persons must
not be in the liquid to be pumped.
The pump may be connected only by

means of a safety switch for fault currents, with
a rated opening current up to 30 mA and a socket
with an earth contact installed in conformity with
the regulations.
Protection: at least 10 Amps.
Operation in swimming pools and garden ponds is
admitted.
For other operation, the provisions in conformity with
the standard VDE 0100 part 702 must be respected.

CAUTION: Before checking, connect the pump and
the system with no voltage!
Replacing the line connecting up with the mains
requires using special tools and therefore may be
done only by the manufacturer or its service engineers.

The pump may operate only with a pipe connecting
the appliance (extension) that is no lighter than a
rubber hose mod. H07 RNF in conformity with the DIN
57282 or DIN 57245 standard.

(For your safety)
The voltage (230 Volts alternating current) indi-
cated on the pump’s rating plate must correspond

to the available mains voltage.
Before starting it is necessary to make sure by having a
check made by qualified personnel that there are the
necessary electrical protection measures.
• Earth connection.
• Earthed neutral.
• The safety switch for fault currents corresponds to the

safety regulations of the electricity board and functions
perfectly.

• Plug connections must be protected from water. If there

is a risk of flooding, plug connections must be placed
somewhere safe.

• Definitely avoid pumping aggressive liquids and abrasive

products.

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.

SUBMERSIBLE PUMP

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;

b) or if GENUINE SPARE PARTS are not used to replace

parts;

c) or if the indications and provisions given in the instruc-

tions handbook are not complied with.
The same provisions hold for the accessories.

Resistance

The maximum temperature of the delivery liquid should
never 35

C in continuous operation.

Infiammable, combustible or explosive liquids cannot
be conveyed with this pump!
In particular, do not use engine fuels, detergents, or other
chemical products.

2. Use

CAUTION! Sector of use

“DRAINAGE” – To transfer and empty fresh to
slightly polluted water from rainwater barrels and
casks.

“VORTEX” – Portable submersible pump for
discharge and waste water with solids in suspen-
sion.
Also used as emergency pump, in case of over-
flowing with muddy water, thanks to its large
suction filter.

To achieve excellent motor cooling the pump
casing is provided with a breather hole that enables
water to flow out.
The pump must be protected from running dry.

Starting

First put the pump into water and then
connect the plug.
The pump is ready for use.

3. Before starting

Installation of your canned motor pump is:
• fixed with a fixd pipe, or
• fixed with a flexible hose.

Take care
When installing it is necessary to take care that the pump
is never fitted hanging from its delivery pipe, but is always
placed in a raised position with respect to the bottom of

�

the well so that the muddy bottom is not sucked up with
the water.
Never handle or hang the pump by gripping the power
supply cable.
In pumps with a floating switch, the latter is adjusted in
order to make immediate starting possibile.

Note
The pump well must have minimum dimensions of
40x40x50 cm. so that the floating switch can move freely.
It is also possible to use round, prefabricated concrete
wells with an inner diameter of approx. 40 cm.

4. Maintenance instructions

Your canned motor pump is a quality product, free from
maintenance. It has been subjected to rigorous final
checks.
However, for a long service life and continuous operation,
we recommend constant care and regular checks.

•

Before every maintenance job, disconnect the plug.

• F

or transportable use the pump should be washed with

clear water after every use.

• F

or fixed installation it is recommended to check the

operation of the floating switch every 3 months.

•

Using a jet of water, get rid of the fibre and spindly

particles that may get deposited in the pump’s cassing.

•

In the event of excessive deposits in the pump cassing,
dismantle the inlet filter by unscrewing the star screw.
Wash the pump casing and fit the inlet filter back on.

• E

very 3 months remove the mud from the bottom and

walls of the well.

• Eliminate the deposits from the floating switch, washing

it with fresh water.

•

Protect the pump from frost.

CAUTION!

“DRAINAGE”
Special instructions: It is not suitable for pumping:
sewage, sandy water.
The pump must never run dry.
The manufacturer’s warranty is null and void in
the event of damage to the pump caused by it
running dry.

“VORTEX”
The pump must never run dry.
The manufacturer’s warranty is null and void in
the event of damage to the pump caused by it
running dry.

CAUSES

The motor will not work

The motor works, the pump will not convey

Defective protection device
Motor protection disconnected, pump straining/blocked
Dry operation protection disconnected, the water level has fallen too much
Defective pump

Clogged suction opening
Check valve blocked or delivery pipe bent
Delivery pipe clogged

oreign bodies in the pump, pump impeller blocked

The pump runs dry

If it is not possibile to eliminate the trouble, please call our service department.
