1. SAFETY INSTRUCTIONS
KEY
The following symbols have been used in the discussion:
Situation of general danger.
Failure to respect the instructions that follow may cause harmto persons and property.
Situation of electric shock hazard.
Failure to respect the instructions that follow may cause a situation of grave risk for personal safety.
Notes
These instructions must be observed for explosion-proof pumps.
WARNINGS
Read this documentation carefully before installation. Installation and operation must comply with the local safety
regulations in force in the country in which the product isinstalled. Everything must be done in a workmanlike manner.
Failure to respect the safety regulations not only causes risk to personal safety and damage to the equipment, but invalidates

ENGLISH
17
every right to assistance under guarantee.
PERSONNEL QUALIFICATIONS
Installation, commissioning and maintenance must be carried out by competent, skilled personnel in possession of
the technical qualifications required by the specific legislation in force.
The term skilled personnel
means persons whose training, experience and instruction, as well as their knowledge of the
respective standards and requirements for accident prevention and working conditions, have been approved by the person in
charge of plant safety, authorizing them to perform all the necessary activities, during which they are able to recognize and
avoid all dangers. (Definition for technical personnel IEC 364).
The appliance is not intended to be used by persons (including children) with reduced physical,sensory or mentalcapacities,
or who lack experience or knowledge, unless, through the mediation of a person responsible for their safety, they have had
the benefit of supervision or of instructions on the use of the appliance. Children must be supervised to ensure that they do
not play with the appliance.
SAFETY
Use is allowed only if the electric system is in possession of safety precautions in accordance with the regulations
in force in the country where the product is installed (for Italy CEI 64/2).
The pump must be provided with a device for isolating the power supply complying with the requirements of
standard EN60204-1 5.3.2.
Pump installation in tanks must be carried out by specially trained persons.
Work in or near tanks must be carried out according to local regulations.
For safety reasons,all work in tanks must be supervised by a person outside the pump tank.
It is advisable to make all maintenance and service jobs when the pump is placed outside the tank.
Tanks for submersible sewage and wastewater pumps may contain sewage or wastewaterwith toxic and/or disease-causing
substances. Therefore, all persons involved must wear appropriate personal protective equipment and clothing, and all work
on and near the pump mustbe carried outunder strict observance of the hygiene regulations in force.
Never tamper installed protections and safety devices; when
necessary, ask for intervention of competent
personnel.
Be sure to operate in safety conditions with well dimensioned equipment and instrumentations complying with local
safety regulations and standards.
Failure to observe the warnings may create situations of risk for persons or property and will void the product guarantee.
RESPONSIBILITY
The Manufacturer does not vouch for correct operation of the electropumps or answer for any damage that they
may cause if they have been tampered with,
modified and/or run outside the recommended work range or in
contrast with other indications given in this manual.
The Manufacturer declines all responsibility for possible errors in this instructions manual, if due to misprints or errors in
copying.The Manufacturer reserves the rightto make any modifications to products that it may consider necessary or useful,
without affecting their essential characteristics.
POTENTIALLY EXPLOSIVE ENVIRONMENTS
Use explosion-proofpumps for applications in potentially explosive environments.
FKV and FKC pumps must under no circumstances pump combustible liquids.
The classification of the installation site must be approved by the local fire-
fighting authorities in each individual
case
Special conditions for safe use of FKV and FKC explosion-proofpumps:
1. Make sure thatthe thermal switches are connected in the same circuitbut have separate alarm outputs (motorcutout) in
the event ofa high temperature in the motor.
2. Bolts used for replacementmust be class A2-70 or better according to EN/ISO 3506-1.
3. Contact the manufacturer for information on the dimensions of the flameproofjoints.

ENGLISH
18
4. THE PUMP MUST ALWAYS BE SUBMERGED WHEN WORKING.The level of pumped liquid must be controlled by two
level switches connected to the motor control circuit. The minimum level depends on the installation type and is specified
in these installation and operating instructions.
5. Make sure the permanently attached cable is suitably mechanically protected and terminated in a suitable terminal board
placed outside the potentially explosive area. The pump is supplied with an appropriate
power supplycable.
6. The sewage pumps have an ambient temperature range of -20 °C to +40 °C and a maximum process temperature of
+40 °C. The minimumambient temperature for a pump with a water-in-oil sensor is 0 °C.
7. The thermal protection in the stator windings has a nominal switch temperature of 130°C and must guarantee the
disconnection of the power supply; the power supply must be reset manually.
2. GENERAL DESCRIPTION
This manual contains the instructions for the installation, operation and maintenance of submersible pumps of the FK series. The pumps
are equipped with electric motors with power between 1.1 and 11 kW.
The pumps in the FK series are designed and suitable for pumping domestic and industrial sewage and waste waters compatible with
the materials of which the pumps are made.
The pumps can be installed on an auto-coupling system or stand freely on the bottom of a tank.
The booklet also includes specific instructions for the explosionproofpumps.

5. INSTALLATION
Before beginning installation procedures, carry out these checks:
• Does the pump correspond to order?
• Is the pump suitable for the supply voltage and frequency available atthe installation site?
• Are accessories and other equipment undamaged?
When choosing the installation site, check that:
1. The voltage and frequency on the pump’s technical data plate correspond to the values of the
power supply
system.
2. The electrical connection is made in a dry place,far from any possible flooding.
3. The electric system must be approved by the safety regulations in force and in good condition.
The construction of tanks, reservoirs or sinkholes where the electropump is to be housed, as well as its positioning with
respect to the level of the sewage network, are subject to standards and legalregulations that mustbe respected.
Before beginning the installation, switch off the power supply and lock the mains switch in position 0 with a padlock
to ensure that the power supply cannot be accidentally switched on. Any external voltage connected to the pump
must be switched off before working on the pump.
For further details on the accessories, see the pump technicaldata sheet or contact DAB Pumps.
Fix the extra nameplate supplied with the pump to the cable end in the control cabinet.
All safety regulations must be observed atthe installation site,e.g. the use of blowers for fresh-air supply to the tank.
Do not put your hands or any tool into the pump suction or discharge port after the pump has been connected to
the power supply, unless the pump has been switched off by removing the fuses or switching off the mains switch.
It must be ensured that the power supply cannot be accidentally switched on.
We recommend to always use Dab Pumps accessories to avoid malfunctions due to incorrect installation.
Only use the lifting bracket for lifting the pump. Do not use it to hold the pump when in operation. Check that the
tools and equipment used for handling, lifting and lowering it into the sinkhole are suitable for the
weight to be
lifted,efficient and complying with the safety laws in force.

ENGLISH

Installation types
The FKVand FKC pumps are designed for two installation types:
• submerged installation on auto-coupling,
• free-standing submerged installation on ring stand.
Before installation, check that the bottom of the tank is flat and uniform.
Check that pit, pool or tank are well dimensioned and that water level assures a correct running of electric pump
with limited startings per hour.
5.1 Submerged installation on an automatic coupling device
Pumps for permanent installation can be installed on a stationary auto-coupling guide rail system. The auto-coupling system facilitates
maintenance and service as the pump can easily be lifted out of the tank.
In the case of a potentially explosive atmosphere, before starting installation
operations, check that the pump is
suited for working in that atmosphere.
Make sure that the piping is correctly installed so that the pump does not have to bear loads due to the weight of
the pipes.
Do not use elastic elements or bellows in the pipework; these elements should never be used as a means to align
the pipework.

Proceed as follows:
- Fix the upper bracket for the guide pipes (fig. 5 – pos. A ) to the
edge of the pit.
- Locate at bottom of pit the foot pedestal for the automatic coupling
(fig. 5 – pos. B) and check that the guide pipe conical fixations are
perfectly perpendicolar and leveled to the correspondent fixations
of the upper bracket located to the edge of the pit.
- Mark the position of the slots in the support foot, then measure the
exact length ofthe guiding pipes (fig.5 - pos. C).
- Fix firmly the pedestal foot to the bottom of pit with suitable anchor
clamps or metallic blocks.
- Connect the delivery pipe to the footpedestal outlet.
- Disassemble the upper brackets from the edge of the pit and insert
in the conical fixations of the foot pedestal the guide pipes
previously cutted of correct length and fix them to the brackets
reassembling the same to the edge of the pit.
- Assemble the special skid-flange (fig. 5 – pos. D) on the delivery
outlet of the pump and hook the rope or chain to the handle or slot
located on the upper partof it.
- Liftthe electric pump up to over the pitand let it slowly descend guiding

- When it arrives at the bottom, the electropump will automatically connect to the support foot.
- The hook of lifting rope or chain must be in line with the center of gravity of pump.
- Secure the extremities ofrope or chain to the upper bracket located atthe edge of the pit.
- Dispose the electric cables avoiding bends and deflections and paying attention that relevant terminals are not in contact with
water.
The correct fixed installation must include installation of a non-return valve.
The guide rails must not have any axial play as this would cause noise during pump operation.
During positioning of the pump, air may remain blocked inside the pump body. The air may
be removed from the pump body by installing the pump after having removed the cap of the
vent hole positioned on the side of the pump. (Fig. 6).
Attention,the vent hole is on the side opposite the oil filling holes.
5.2 Submerged installation on a support base
Delivery pipe must have diameter notinferior to the pump inlet.
When using a flexible pipe , it is advisable a reinforced pipe with metallic spiral which maintains the section unchanged even in presence
of bends.
The eventual foot valve and gate valve must be assembled at a distance of approx 50 ÷ 200 cm. in a section of metallic pipe (rigid).
Special attention should be paid to the positioning of electric cables in order to avoid possible bending, pressing,lifting and that the same
are accidentaly sucked by the pump.
The free end of the cable must not be submerged, as water may penetrate through the cable into the motor.
Fig. 7 Submerged installation on a support base
6. ELECTRICAL CONNECTION
Attention: always respect the safety regulations!
Electrical installation must be carried out by an expert, authorised electrician, who takes on all responsibility and
respects the regulations in force.
The system must be correctly and safely earthed as required by the regulations in force.
The control panel and respective electrical equipment, when contemplated, must be of a type approved by the safety
regulations in force.
Instruments and components of the panel must be of an adequate capacity and quality to maintain
reliable operation over time.
In potentially explosive environments,
the electrical connection and the control panel must be provided with
explosion-proof protection.

as to be removed or dismantled, the
earth lead must be removed last.
The installer is responsible f
or ensuring that the earthing system is efficient and made in compliance with the
regulations in force.
For explosion-
proof pumps the electrical and equipotential connection must be made according to standard EN
60079-14.
Before installation and the first start-
up of the pump, check the condition of the cable visually to avoid short
circuits.
If the power cable is damaged, it must be replaced by the manufacturer’s service centre or by another qualified
person.
On explosion-proof pumps, make sure that an external earth conductor is connected to the external earth terminal
on the pump.
The section of the earthlead must be at least 4mm², yellow/green.
Make sure thatthe earth connection is protected from corrosion.
Make sure thatall protective equipment has been connected correctly.
Float switches used in potentially explosive environments must be approved for this application.
Set the motor-protective circuit breaker to the rated current of the pump. The rated current is stated on the pump
nameplate.
The supply voltage and frequency are marked on the pump nameplate.The voltage tolerance must be within - 10 %/+ 10 % of the rated
voltage. Make sure thatthe motor is suitable for the power supply available atthe installation site.

6.2 Electric panel level switches
During operation the electropump must be immersed in the pumped liquid. It is necessary to install a control system with
level switches (level probes or floats or other appliances) thatensure the minimum level of liquid and protect the electropump
against dry running.
When installing the level switches, observe the following points:
•To prevent air intake and vibrations install the stop level switch in such a way that the pump is stopped before the liquid level is
lowered below the top of the cable entry.
•In tanks with one pump, install the start level switch in such a way that the pump is started at the required level; however, the
pump must always be started before the liquid level reaches the bottom inlet pipe to the tank.
•In tanks with two pumps, the start level switch for pump 2 must start the pumpbefore the liquid level reaches the bottom inlet pipe
to the tank, and the start level switch for pump 1 muststart this pump correspondingly earlier.
•If installed,always install the high-level alarm switch about 10 cm above the start level switch; however, the alarm mustalways be
given before the liquid level reaches the bottom inletpipe to the tank.
For further inf
ormation on electric panels and the
respective use of level switches, contact DAB Pumps.
Fig. 9 Start and stop levels
Make sure thatthe effective volume ofthe tank does
not become so low thatthe number of starts per hour
exceeds the maximum permissible number.
Switches or sensors in potentially explosive
environments must be certified for this application.
6.3 Thermal switch
All FKV and FKC pumps have thermal protection incorporated in the stator windings (see wiring diagrams, contacts k1, k2) See parag.
6.1.
The thermal switches are inserted in the motor windings and intervene by opening and interrupting the circuit when an excessive
temperature is reached in the windings (about 150°C).
Non explosion-proof pumps
For correct operation the thermal switch must be connected to a device for interrupting the power supply circuit of the
electropump.
When the electropump has cooled, once the circuit of the thermal switch has been reset, the device can
automatically restart the pump.
Explosion-proof pumps
The device for interrupting the power supply circuit of explosion-
proof pumps must not restart the pump
automatically. This ensures protection against over temperature in potentially explosive environments.

6.4 Sensor (water in theoil) (not available for explosion-proof versions)
The sensor probe inserted in the oil chamber detects any presence of water in the oil when the water percentage exceeds a
predetermined value.
When the water level in the oil is reached, the probe closes the circuit between the sensor (contact S1 on wiring diagram) and the
equipotential contact of the pump.
The probe must be connected to a suitable device in the control panel; the device may give an acoustic alarm or a luminous signal or,
when requested,it may stop the electropump.
If the signal is activated you must stop the electropump, dismantle it and check the state of the oil, the mechanical seals, and look for the
causes ofintervention.
7. START-UP
Before starting work on the pump, check that the main switch is off.
It must be ensured that the power supply cannot be accidentally switchedon.
Make sure that all protective equipment has been connected correctly.
The pump must not run dry.
The pump must not be started if the atmosphere inthe tank is potentially explosive.
Before starting the pump, check that it is suitably connected to the pumping system to avoid uncontrolled leakage
of liquid.
Do not put your hands or any tool into the pump suction or discharge port after the pump has been connected to
the power supply.
7.1 General start-up procedure
This procedure applies to new installations as well as after service inspections if start-up takes place some time after the pump was
placed in the tank.
- After long periods of storage, check the conditions of the oil in the oil chamber. See also section 8.1 Routine maintenance.
- Check thatthe system,bolts, gaskets, pipework and valves etc.are in correct condition.
- Mount the pump in the system.
- Switch on the power supply.
- Check whether the monitoring units, ifused, are operating satisfactorily.
- Check the setting of the float switches or of the level sensors.
- Check thatthe impeller can turn freely by briefly startingthe motor.
- Check the direction of rotation.See section 7.2 Directionof rotation.
- Open the isolating valves, if fitted.
- Check that the liquid level is above the motor for S1 operation and above the cable entry for S3 operation. See fig. 9. If the
minimum level is notreached do not start the pump.
- Start the pump and let the pump run briefly, and check if the liquid level is falling.
- Observe if the discharge pressure and input current are normal.If notthere mightbe air trapped inside the pump (See section 5
Installation).
In case of abnormal noise or vibrations from the pump, other pump failure or power supply failure or water supply
failure, stop the pump immediately. Do not attempt to restart the pump until the cause of the fault has been found
and the fault corrected.
After one week of operation or after replacement of the shaft seal, check the condition of the oil in the chamber. For pumps without
sensor, this is done by taking a sample of the oil. See section 8. Maintenance and service for procedure. Every time the pump has been
removed from the tank, go through
the above procedure when starting up again.
7.2 Direction of rotation
The pump may be started for a very short period without being submerged to check the direction of rotation.
Check the direction of rotation before starting up the pump. An arrow on the motor housing indicates the correct direction of rotation.
Correct direction of rotation is clockwise when viewed from above.

ENGLISH
27
Checking the direction of rotation
The direction ofrotation should be checked in the following way every time the pump is connected to a new
installation.
Procedure
1. Let the pump hang from a lifting device, e.g. the hoist used for lowering the pump into the tank.
2. Start and stop the pump while observing the movement (jerk) of the pump. If connected correctly,
the pump will rotate clockwise, i.e. it will jerk counter-clockwise. See fig. 10. If the direction of
rotation is wrong, interchange any two of the phases in the power supplycable.
8. MAINTENANCE AND SERVICE
Routine maintenance work, limited to checking, cleaning or replacing limited parts, may be carried out only by expert and
qualified personnel,provided with suitable equipment, who know the safety regulations for the working environment and have
read and carefully checked the contentof this manual and ofany other documentation attached to the product.
Special maintenance or repairs mustbe entrusted to authorised Dab Pumps service centres.
Before starting any work on the system or troubleshooting, ensure that the main switch is off and that the power
supply cannot be switched on again accidentally. Check that all the protection systems are correctly connected and
that all the rotating parts are stopped.
Maintenance work on explosion-proof pumps must be carried out by DAB Pumps or a service workshop authorized
by DAB Pumps.
However, this does not refer to hydraulic components such as the pump body, the impeller and the mechanical seal.
The replacement of the cable must be carried out exclusively by the manufacturer’s service centre or by another
qualified person.
The pump may have been used for pumping liquid that is harmful to health, contaminated or toxic. Take all the
precautions concerning health and safety before carrying out maintenance or repairs.
Use genuine spare parts only for repairs.
Select the spare parts to be ordered,consulting the exploded drawings available on the DAB Pumps site or the DNA selection software.
The manufacturer declines any responsibility for eventual damages to persons, animals or things for maintenance and repair
interventions carried out by non authorized personnel orwith no genuine spare parts.
Specify the following information when ordering spare parts:
1. The type of electric pump.
2. Serial number and manufacturing year.
3. Denomination and reference number of the spare parts.
4. Required number of parts.
8.1 Routine Maintenance
Pumps running normal operation should be inspected every 3000 operating hours or at least once a year. If the pumped liquid is very
muddy or sandy, inspect the pump at shorter intervals.
Check the following points:
•Power consumption
See pump nameplate.
•Oil level and oil condition
When the pump is new or after replacementof the shaft seal, check the oil level and water contentafter one week of operation. If there is
more than 20 % extra liquid (water) in the oil chamber, the shaftseal is defective. The oil should be changed after 3000 operating hours
or once a year.
•Cable entry
Make sure thatthe cable entry is watertight (visual inspection) and that the cable is notsharply bent and/or pinched.
•Pump parts
Check impeller, pump housing,etc. for possible wear. Replace defective parts.
•Ball bearings
Check the shaftfor noisy or heavy operation (turn the shaft by hand). Replace defective ballbearings.
A general overhaul of the pump is usually required in case of defective ball bearings or poor motor function. This work must be done by
an assistance workshop authorised by DAB Pumps.
Fig. 10 Jerk direction

ENGLISH
28
The ball bearings used are sealed and lubricated, usinga special lubricant for high temperatures (-40°C + 150°C).
Defective bearings may reduce the Ex safety.
•O-rings and similar parts
During service/replacement, it must be ensured that the grooves for the O-rings as well as the seal faces have been cleaned before the
new parts are fitted.
Used rubber parts must not be reused.
Explosion-proof pumps must be checked by an authorized Ex workshop once a year.
•Oil change
After 3000 operating hours or once a year, change the oilin the oil chamber as described below.
If the shaftseal has been replaced, the oil must be changed.
When loosening the screws of the oil chamber, note that pressure may have built up in the chamber. Do not remove
the screws until the pressure has been fully relieved.
•Draining of oil
1. Place the pump on a plane surface with one oil screw pointing downwards.
2. Place a suitable container (approx.1 litre), for instance made of transparent plastic material, under the oil screw.
Used oil must be disposed of in accordance with local regulations.
3. Remove the lower oil screw.
4. Remove the upper oil screw. If the pump has been in operation for a long period of time, if the oil is drained off shortly after the
pump has been stopped, and if the oil is greyish white like milk, it contains water. If the oil contains more than 20 % water, it is
an indication that the shaft seal is defective and must be replaced. If the shaft seal is not replaced, the motor will be damaged. If
the quantity of oil is smaller than the quantity stated, the shaftseal is defective.
5. Clean the faces for the gaskets for oilscrews.
•Filling with oil
1. Rotate the pump so that one of the two oil holes in a vertical position facing upwards.
2. Pour the oil into the chamber. The suitable amount of oil is indicated by the second oil
venting hole (positioned beside the vertical filling hole). Once the oil has reached and
escapes from the hole at the side, the oil quantity is correct.
3. Fit the oil screws with new gaskets.

8.2 Special maintenance
Special maintenance operations must be carried out exclusively by an assistance workshop authorised by DAB Pumps.
8.3 Contaminated pumps
If a pump has been used for a liquid which is injurious to health or toxic, the pump will be classified as
contaminated.
If you are asking to have a pump repaired, you must contact the service centre to give them the details about the pumped liquid, etc.,
before sending the pump for repair. Otherwise,the service centre may refuse to acceptthe pump.
However, any application for service (no matter to whom it may be made) must include details about the pumped liquid if the pump has
been used for liquids which are injurious to health or toxic.
Before a pump is returned, it mustbe cleaned in the bestpossible way before it is returned.
