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.

DANGER - ELECTRIC SHOCK RISK

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

DANGER

GB TRANSLATION OF THE ORIGINAL INSTRUCTIONS

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

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

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.

TRANSLATION OF THE ORIGINAL INSTRUCTIONS

• 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.

DANGER - ELECTRIC SHOCK RISK

• 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.
