future reference
The appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
(CEI EN 60335-1 : 08)
The power cord must never be used to carry or move the pump. Always use the pump’s handle.
When handling the pump, while it is connected to the electric power supply, you should avoid
all contact with water.
Never remove the plug by pulling on the power cord.
Before taking any action on the pump, always remove the plug from the power socket.
There should be no individuals present in the liquid that is being pumped while the pump is in
use.
If the power supply cord has been damaged, it must be replaced by the manufacturer or his
authorized customer support service in order to avoid all risks.
The pump is equipped with a thermal overload safety device. In the event of any overheating of
the motor, this device automatically switches off the pump. The cooling time is roughly 15 to 20
minutes, then the pump automatically comes on again. If the overload cutout is tripped, it is
essential to identify and deal with the cause of the overheating. See Troubleshooting.

USE
Multi-impeller submersible pumps with 2, 3 or 4 impellers ideal for rain water and mains irrigation
systems, for pumping water from tanks, ponds and wells and other applications that require high
pressure.
The multistage submersible pumps must only be used in clean water.
The pump should ideallybe completely submersed for it to operate correctly, but can be used at a
minimum suction height of 1”1/2 for very short periods.
•
Available in an automatic version with a float switch for automatic starting and stopping of the
pump.
Characteristics:
•
Optimum motor cooling that allows the pump to be used also when it is only
•
Stainless steel anti-deposit filter
•
Non-return valve and 4-way connector.
The temperature of the fluid being pumped must never exceed 95°F
The pump must not be used to pump salt water, sewage, flammable, corrosive or explosive

STARTING THE PUMP
Given the different provisions applicable to the safety of electric systems in different countries,
make sure that the pump system, as concerns its intended use, is in accordance with current
legislation.
Before starting the pump, make sure that:
•
The voltage and frequency specified on the pump’s nameplate coincide with those of the
available power supply;
•
there are no signs of damage to the pump or its power cord;
•
The electric connection is made in a dry place, protected against any risk of flooding;
•
The electric system is complete with a residual current circuit-breaker GFI Ground fault Indicator
(l An S 30 mA) and an efficient earthing connection;
•
Any extension cords must comply with the requirements od the DIN VDE Standard 0620
Insert the plug of the power cable into a suitable power socket.
Automatic operation:
The floating switch starts and stops the pump automatically.
The water level that prompts the starting and stopping of the pump can be adjusted by changing
the length of cable of the float between the holder and the float.
NB
The length of the float cable must never be shorter than ½”.
Manual operation:
a) The floating switch must be lifted in order to start pumps with a float.
b) For pumps without a float, insert the plug.

RECOMMENDATIONS
To ensure the proper operation of the pump, it is important to comply with the following
recommendations:
The pump must never be allowed to run dry.
Never leave the pump in operation when the delivery pipe is clogged.
•
The pump must only be used when it is immersed in water. If the water runs out, the pump must be
stopped immediately by removing the plug from the power supply.
•
Pay careful attention when the pump is operated in manual mode.
•
The pump must be placed in a stable position inside a trap or in the lowest part of the place where it is
installed.
•
The float must be able to move freely while the pump is running therefore the advised dimensions of
the trap are 1”1/4 x 1”1/4.
Periodically, it is advisable to make sure the no dirt (leaves, sand, etc) has accumulated in the
collection trap or around the suction grid.
MAINTENANCE AND CLEANING
lt is absolutely essential to prevent any risk of the pump freezing. In the event ol freezing temperatures.
remove the pump from the liquid, empty it and keep it in a place where it cannot freeze.
The pump must be disconnected from the mains before performing any cleaning operation.
The pump is maintenance free.

FAULT
CAUSE
SOLUTION
The motor does not
start or makes no
noise
1)The motor is not powered.
2) There is no water (pump not
Enabled by the float switch)
1) Check if power is supplied to the socket
and that the plug is correctly inserted
2) Check the water level, make sure the float
can move freely.
The pump delivers no
water
1) The suction grid or piping are
clogged
2) The impeller is worn or stuck
3) The required head is too high for
the characteristics of the pump.
4) Water level under the suction
minimum
1) Remove the obstruction correctly sealed
and start the pump again.
2) 2) Replace the impeller or remove the
obstruction.
The pump does not
stop (automatic
version only)
1) The pump is not disabled by the
float
1) Make sure the float can move freely
Flow rate to low
1) The suction grid or pipe work is
partically clogged.
2) The impeller is partically clogged
or fouled
1) Remove any obstruction.
2) Remove any obstruction.
The Pump stops
running (possible
intervention of the
overload switch).
Make sure the fluid being pumped is
not too dense, causing the motor to
overheat.
- Make sure the temperature of the
water is not too high.
- Make sure there is no solid body
obstructing the impeller.
- Power supply doesn’t comply with
