WARNINGS
For the safety of individuals and objects.
Carefully follow the instructions marked with the following symbols.
FEATURES
CHAPTER 1
DOMINATOR electropumps are suitable to pump clear water that contains no dissolved gases.
The electropumps of this series are multiphase centrifugal and submergible pumps. The parts that come into contact with water
are all suitable to be used with cooking water. Every electropump has been carefully tested and packed. On receiving the product,
verify that the electropump has not been damaged during transport. If damage is reported, immediately contact the dealer within
and no later than 8 days from the purchase date.
Read this manual carefully before installing this pump. Any damage caused by failure to observe the directions contained in this
manual will not be covered by warranty.

INSTALLATION
CHAPTER 3
LIMITATIONS
• Max. Temperature of pumped liquid
40° C continuous operation
• Max.On/off cycles/hour
30 equally spaced
• Max. Immersion depth 17 m
• It is advisable to fit a check valve to
prevent the fluid from re-circulating
when the pump is stopped. Avoid
using the electric cable to lift or
transport the pump.
• Use a stainless steel or nylon rope,
suitable to sustain the weight, to
immerse the electropump.
• 1 slot only has been provided to
anchor the electropump.
• Maximum dimension of pumped solid
objects 2 mm
• Maximum amount of sand
50 g/m3
• Anchor the rope so that it balances
the weight of the electropump.
• It is advisable to connect the electric
cable to the delivery with plastic
straps, at a distance of about 3 m,
when using rigid piping.
• It is also advisable to fit automatic
level controls to prevent the
electropump from running without
liquids and a pressure gauge (suitable
to the electropump model) to verify its
performance during operation.
• Minimum diameter of the well
135 mm DOMINATOR 5"
(without float)
• Minimum diameter of the well
100 mm DOMINATOR 4"
(without float)
• The automatic DOMINATOR model is
equipped with a pre-set float switch
(See fig.1). To change the adjustement
range, increase or decrease the free
piece of float switch cable by sliding it
through the seat on the handlebar.
Verify that the electropump never runs without liquids.
WARNING
The electropump cannot be used to move inflammable or dangerous liquids.
WARNING
During installation, verify that the pump is disconnected from the electrical supply.
Make sure that the float switch stops the pump, when the min. level of liquid is reached.
Make sure no obstacles obstruct the movement of the float switch.
This appliance can be used by children aged 8 years or over and by persons with limited physical, sensory or
intellectual capabilities, or with limited experience and knowledge, provided that they are supervised or have
been instructed in the safe use of the appliance and are aware of the dangers involved. Children must not
be allowed to play with the appliance. Cleaning and user maintenance must not be carried out by children
unless they are supervised.

WARNING
WARNING
DANGER
The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming
of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index
(MEI) is based on the full impeller diameter. The operation of this water pump with variable duty points may be more efficient and
economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system information
on benchmark efficiency is available at: www.europump.org/efficiencycharts
Pollution of the liquid could occur due to the leakage of lubricants

ELECTRICAL CONNECTIONS
CHAPTER 4
The installer must make sure that the electric system is grounded in accordance with the law in force.
Make sure that the electric system has a (RCD) high-sensitivity circuit breaker D=30 mA.
Verify that the voltage and frequency of the electropump shown on the nameplate correspond to those
available on the mains.
DANGER - ELECTRIC SHOCK RISK
DANGER - ELECTRIC SHOCK RISK
WARNING
Electropumps have a plug with double ground contact at the end of the power supply cable. In this case the electropump
is grounded by inserting the plug in the socket.
DOMINATOR is a single-phase electropump with in-built thermal circuit breaker and automatic reset and doesn't therefore
require any external protections.
OVERLOAD PROTECTION
Use the electropump for the applications listed on the nameplate.
Do not operate the electropump without liquids, to avoid damaging hydraulic parts and seal.
Do not operate the electropump when the interception valve on the delivery side is completely closed.
WARNING
WARNING
WARNING
STARTING THE UNIT (SEE PICTURE 1 PAGE 91)
CHAPTER 5
Connect the pipe to the 1" 1/4 delivery mouth before starting the electropump. Connections must be made so as to avoid losses.
Start the pump by inserting the plug in an appropriate outlet.

• Under normal conditions DOMINATOR
electropumps do not need any type
of maintenance. In order to avoid
possible failures, it is advisable to
periodically check the pressure
supplied and current absorption.
• A decrease in pressure is a symptom
of wear. An increase in current
absorption is a sign of abnormal
mechanical friction in the pump
and/or motor.
• If the electropump is not going to be
used for long periods of time it should
be emptied completely, rinsed with
clean water and put in a dry place.
MAINTENANCE AND TROUBLESHOOTING
CHAPTER 6
Make sure the machine is disconnected from electric power supply, before performing servicing operation.
The power cord must be replaced by the manufacturer or the Customer service, using special tools.

• If the sucked water is not perfectly
clean, it may be necessary to clean
the filter with a steel brush to scrape
the dirt accumulated on the external
surface.
• It is also possible to clean the internal
section of the filter.
• Loosen the screw that fixes the filter
to the body of the electropump and
remove it.
• Scrape the dirt with a steel brush and
rinse it with clean water.
• If this is not sufficient, have the
hydraulic parts cleaned by an
authorised centre.
CLEANING THE FILTER
If the problem cannot be eliminated after carrying out the above-described operations contact the closest service centre.
PROBLEM POSSIBLE CAUSE REMEDY
THE ELECTROPUMP DOES NOT PUMP WATER, THE
MOTOR DOES NOT RUN
1) No power. 1) Check the presence of voltage and if the plug is plugged in properly.
2) Motor protection tripped. 2) Verify the cause and reset the switch. If the thermal circuit breaker has tripped wait
for the system to cool down.
3) Defective condenser. 3) Replace the condenser.
4) Shaft blocked. 4) Verify the cause and unblock the electropump.
THE MOTOR RUNS BUT THE ELECTROPUMP DOES NOT
PUMP LIQUID
1) The pump is sucking air. 1)
• Make sure that the joints are airtight.
• Check that the level of liquid has not dropped below the minimum priming level.
2) The pump rotates in the wrong direction 2) Reset the direction of rotation.
3) Suction grid blocked. 3) Clean the suction grid.
4) Check valve blocked. 4) Clean or replace valve.
THE ELECTROPUMP STOPS AFTER RUNNING FOR
A SHORT PERIOD OF TIME BECAUSE ONE OF THE
THERMAL MOTOR CIRCUIT BREAKER TRIPS
1) The power supply does not conform with the data
on the nameplate.
1) Check the voltage on the power supply cable leads.
2) A solid object is blocking the impellers. 2) Take the electropump to an authorised centre so that it can be disassembled and
completely cleaned.
3) The liquid is too thick. 3) Change the type of electropump.
