GENERAL DESIGN OF A FLYGT PUMP
The stator is insulated in accordance with class F
(155°C, 310°F). The motor is designed to deliver its
rated output at ± 5% variation from the rated voltage.
Without overheating the motor, ± 10% variation from
the rated voltage can be accepted provided that the
motor does not run continuously at full load. The
motor is designed to operate at a voltage imbalance
of up to 2% between the phases.

Monitoring equipment
The stator incorporates thermal contacts connected in
series for some versions.
INSTALLATION
Handlingequipment
Lifting equipment is required for handling the pump.
— Stay clear of suspended loads.
— Always lift the pump by its lifting
handle - never by the motor cable
or the hose.
The minimum height between the lifting hook and the
floor shall be sufficient to lift the pump out of the
sump.
The lifting equipment shall be able to hoist the pump
straight up and down in the sump, preferably without
the need for resetting the lifting hook.
Oversize lifting equipment could cause damage if the
pump should stick when being lifted.
Make sure that the lifting equipment is securely
anchored.

INSTALLATION
Generalrecommendations
To ensure proper installation, please see the dimen-
sions on the dimensional drawing in the Parts List.
NOTE! The end of the cable must not be submerged.
It must be above flood level, as water may penetrate
through the cable into the junction box or the motor.
Check that the lifting handle and chain are in good
condition.
For automatic operation of the pump (level control),
it is recommended that the level regulators be used
at low voltage. The data sheet delivered with the regu-
lators gives the permissible voltage. Local rules may
specify otherwise.
Clean out all debris from the sump before the pump is
lowered down and the station is started.
— NOTE for Ex version page 3.
— Minimum stop level should be
according to the dimensional
drawing.
— The pump must never run dry or
on snore.
Safety precautions
In order to minimize the risk of accidents in connection
with the service and installation work, the following
rules should be followed:
11. Never work alone. Use a lifting harness, safety
line and a respirator as required. Do not ignore
the risk of drowning!
12. Make sure there are no poisonous gases within
the work area.
13. Check the explosion risk before welding or using
electric hand tools.
14. Do not ignore health hazards. Observe strict
cleanliness.
15. Bear in mind the risk of electrical accidents.
16. Make sure that the lifting equipment is in good
condition.
17. Provide a suitable barrier around the work area,
e.g. a guard rail.
18. Make sure you have a clear path of retreat.
19. Use safety helmet, safety goggles and protective
shoes.
10. All personnel who work with sewage systems
must be vaccinated against diseases to which
they may be exposed.
11. A first-aid kit must be close at hand.
12. Note that special rules apply to installation in
explosive athmosphere.
Follow all other health and safety rules and local
codes and ordinances.
ELECTRICAL CONNECTIONS
— Before starting work on the
pump, make sure that the pump
and the control panel are isolated
from the power supply and cannot
be energized.
— If the pump is equipped with
automatic level control, there is
a risk of sudden restart.
— All electrical equipment must be
earthed. This applies to both pump
equipment and any monitoring
equipment. Failure to heed this
warning may cause a lethal
accident. Make sure that the earth
lead is correctly connected by
testing it.
— If persons are likely to come into
physical contact with the pump or
pumped media (liquid), e.g on con-
struction sites and farms, the
earthed(grounded)socketmust
haveanadditionalearth-(ground-)
faultprotection device (GFI)
connected.
When pumping near a lake (jetties,
beaches,ponds,fountainsetc)
a safety-distance of at least 20 m
(65 ft) between the person and the
pump is applicable.
The pump must never be placed
directly into a swimming pool. If
used in connection with swimming
pools, special safety regulations
apply.
NOTE for Ex version page 3.

ELECTRICAL CONNECTIONS
- All electrical work shall be carried out under the super-
vision of an authorized electrician.
- Local codes and regulations shall be complied with.
- Check on the data plate which voltage supply is valid
for your pump.
- Check that the main voltage and frequency agree with
the specifications on the pump data plate.
- If the pump can be connected to different voltages,
the connected voltage is specified by a yellow sticker.
- Connect the motor cable to the starter equipment as
illustrated in the wiring diagrams.
- When the pump is connected to the public mains it
may cause flicker of incandescent lamps when start-
ing. In this case the supply authority should be noti-
fied before installing the pump.
Conductors that are not in use must be isolated.
The cable should be replaced if the outer sheath is
damaged. Contact an Flygt service shop.
Make sure that the cable does not have any sharp
bends and is not pinched.
Under no circumstances may the starter equipment be
installed in the sump.
NOTE! For safety reasons, the earth conductor
should be approx. 50 mm (2.0") longer than the phase
conductors. If the motor cable is jerked loose by
mistake, the earth conductor should be the last
conductor to come loose from its terminal. This
applies to both ends of the cable.
Thermal contacts are incorporated in the stator for
some versions. The thermal contacts can be
connected to max 250 V, breaking current max 4 A.
Flygt recommends that they be connected to 24 V over
separate fuses to protect the other automatic equip-
ment.
Make sure that the pump is correctly earthed (grounded).
Whenusing a variable-frequency-drive(VFD) the
shielded cable (type NSSHÖU.../3E+St) should be
used in order to fulfil European CE requirements. Con-
tact your Flygt representive and ask your VFD-supplier
for electrical limitations.
Remember that the starting current in direct on-line
starting can be up to six times higher than the rated
current. Make sure that the fuses or circuit breakers
are of the proper rating.
The data plate gives rated current. Fuse rating and
cable shall be selected in accordance with local rules
and regulations. Note that with long cables, the
voltage drop in the cable must be taken into consider-
ation, since the motor’s rated voltage is the voltage
that is measured at the terminal board in the pump.
The overload protection (motor protection breaker) for
direct on-line starting shall be set to the motor rated
current as given on the data plate.
Check the phase sequence in the mains with the
phase sequence indicator.
If intermittent operation is prescribed (see data plate),
the pump shall be provided with control equipment
that provides such operation.
Singlephaseoperation
The Flygt single phase pumps must be equipped with a
starter which has a capacitor.
A special Flygt designed starter is required for the
operation of single phase pumps. The connection of
the motor cable to the starter is shown in the wiring
diagram.
NOTE! It is not possible to change the direction of
rotation of a single phase pump by changing the cable
conductors on the starter. Please contact your nearest
Flygt representative.
