Lifting equipment is always required when handling the unit. It must fulfill the following
requirements:
• The minimum height (contact Xylem for information) between the lifting hook and the
floor must be sufficient to lift the unit.
• The lifting equipment must be able to hoist the unit straight up and down, preferably
without the need for resetting the lifting hook.
• The lifting equipment must be securely anchored and in good condition.
• The lifting equipment must support weight of the entire assembly and must only be
used by authorized personnel.
• Two sets of lifting equipment must be used to lift the unit for repair work.
• The lifting equipment must be dimensioned to lift the unit with any remaining pumped
media in it.
• The lifting equipment must not be oversized.
NOTICE:
Oversized lifting equipment could cause damage if the unit should stick when being
lifted.
Temperature ranges for transportation, handling and storage
Handling at freezing temperature
At temperatures below freezing, the product and all installation equipment, including the
lifting gear, must be handled with extreme care.
Make sure that the product is warmed up to a temperature above the freezing point before
starting up. Avoid rotating the impeller/propeller by hand at temperatures below the
freezing point. The recommended method to warm the unit up is to submerge it in the
liquid which will be pumped or mixed.
NOTICE:
Never use a naked flame to thaw the unit.
Unit in as-delivered condition
If the unit is still in the condition in which it left the factory - all packing materials are
undisturbed - then the acceptable temperature range during transportation, handling and
storage is: –50°C (–58ºF) to +60°C (+140ºF).
If the unit has been exposed to freezing temperatures, then allow it to reach the ambient
temperature of the sump before operating.
Lifting the unit out of liquid
The unit is normally protected from freezing while operating or immersed in liquid, but the
impeller/propeller and the shaft seal may freeze if the unit is lifted out of the liquid into a
surrounding temperature below freezing.
Units equipped with an internal cooling system are filled with a mixture of water and 30%
glycol. This mixture remains a flowing liquid at temperatures down to –13°C (9°F). Below –
13В°C (9В°F), the viscosity increases such that the glycol mixture will lose its flow properties.
However, the glycol-water mixture will not solidify completely and thus cannot harm the
product.
Follow these guidelines to avoid freezing damage:
10
Flygt 3153 Installation, Operation, and Maintenance Manual
Transportation and Storage
1. Empty all pumped liquid, if applicable.
2. Check all liquids used for lubrication or cooling, both oil and water-glycol mixtures, for

Storage guidelines
Storage location
The product must be stored in a covered and dry location free from heat, dirt, and
vibrations.
NOTICE:
• Protect the product against humidity, heat sources, and mechanical damage.
• Do not place heavy weights on the packed product.
Freezing precautions
The unit is frost-proof while operating or immersed in liquid, but the impeller/propeller
and the shaft seal may freeze if the unit is lifted out of the liquid into a surrounding
temperature below freezing.
Follow these guidelines to avoid freezing damage:
When
Guideline
Before storage
After storage
• The unit must be allowed to run for a short time after raising it to
discharge remaining pumped liquid.
This does not apply to impeller/propeller units.
• The discharge opening must be covered in a suitable way, or placed
facing down so that any still remaining pumped liquid runs out.
• If present, the cooling jacket must be drained manually by opening the
air vent screws at the top of the cooling jacket.
If the impeller/propeller is frozen, it must be thawed by immersing the unit
in liquid before operating the unit.
NOTICE:
Never use a naked flame to thaw the unit.
Long-term storage
If the unit is stored more than 6 months, the following apply:
• Before operating the unit after storage, it must be inspected with special attention to
the seals and the cable entry.
• The impeller/propeller must be rotated every other month to prevent the seals from
sticking together.

General precautions
Electrical Hazard:
• A certified electrician must supervise all electrical work. Comply with all local codes and
regulations.
• Before starting work on the unit, make sure that the unit and the control panel are
isolated from the power supply and cannot be energized. This applies to the control
circuit as well.
• Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep
the end of the motor cable above the liquid level.
• Make sure that all unused conductors are insulated.
• There is a risk of electrical shock or explosion if the electrical connections are not
correctly carried out or if there is fault or damage on the product.
• A permanent-magnet motor generates voltage when the shaft is rotating. Ensure that the
shaft can not rotate before performing any electrical installation.
WARNING:
Do not install the starter equipment in an explosive zone unless it is explosion-proof rated.
CAUTION:
If the pump is equipped with automatic level control and/or internal contactor, there is a
risk of sudden restart.
Requirements
These general requirements apply for electrical installation:
• The supply authority must be notified before installing the pump if it will be connected
to the public mains. When the pump is connected to the public power supply, it may
cause flickering of incandescent lamps when started.
• The mains voltage and frequency must agree with the specifications on the data plate.
If the pump can be connected to different voltages, then the connected voltage is
specified by a yellow sticker close to the cable entry.
• The fuses and circuit breakers must have the proper rating, and the pump overload
protection (motor protection breaker) must be connected and set to the rated current
according to the data plate and if applicable the cable chart. The starting current in
direct-on-line start can be up to six times higher than the rated current.
• The fuse rating and the cables must be in accordance with the local rules and
regulations.
• If intermittent operation is prescribed, then the pump must be provided with
monitoring equipment supporting such operation.
• If stated on the data plate, then the motor is convertible between different voltages.
• The thermal contacts/thermistors must be in use.
• For FM-approved pumps, FLS must be connected and in use in order to meet approval
requirements.
22
Flygt 3153 Installation, Operation, and Maintenance Manual
Installation
Cables
These are the requirements to follow when you install cables:
• The cables must be in good condition, not have any sharp bends, and not be pinched.
• The sheathing must not be damaged and must not have indentations or be embossed
(with markings, etc.) at the cable entry.
• The cable entry seal sleeve and washers must conform to the outside diameter of the
cable.
• The minimum bending radius must not be below the accepted value.
• If using a cable which has been used before, a short piece must be peeled off when
refitting it so that the cable entry seal sleeve does not close around the cable at the
same point again. If the outer sheath of the cable is damaged, then replace the cable.
Contact an Xylem service shop.
• The voltage drop in long cables must be taken into account. The drive unit’s rated
voltage is the voltage measured at the cable connection point in the pump.
• The screened cable must be used according to the European CE requirements if a
Variable Frequency Drive (VFD) is used. For more information, contact your Xylem
representative (VFD-supplier).
Earthing (Grounding)
Electrical Hazard:
• You must earth (ground) all electrical equipment. This applies to the pump equipment,
the driver, and any monitoring equipment. Test the earth (ground) lead to verify that it is
connected correctly.
• If the motor cable is jerked loose by mistake, the earth (ground) conductor should be the
last conductor to come loose from its terminal. Make sure that the earth (ground)
conductor is longer than the phase conductors. This applies to both ends of the motor
cable.
• Risk of electrical shock or burn. You must connect an additional earth- (ground-) fault
protection device to the earthed (grounded) connectors if persons are likely to come
into physical contact with the pump or pumped liquids.
Connect the motor cable to the pump
CAUTION:
Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep the
end of the motor cable above the liquid level.

voltage on all three phases.
• Check the fuses. Replace fuses that have tripped.
• If the fuses are intact, notify a certified electrician.
The phase currents vary, or they are
too high.
Contact the local Xylem service shop.

Troubleshooting
Cause
Remedy
The insulation between the phases
and ground in the stator is
defective.
1.
Use an insulation tester. With a 1000 V DC megger, check that the
insulation between the phases and between any phase and ground is
> 5 megohms.
If the insulation is less:
Contact the local Xylem service shop.
2.
The density of the pumped fluid is
too high.
Make sure that the maximum density is 1100 kg/m3 (9.2 lb/US gal)
• Change the impeller, or
• Change to a more suitable pump.
• Contact the local Xylem service shop.
There is a malfunction in the
overload protection.
Replace the overload protection.
If the problem persists, refer to the Flygt Service Guide on the web or contact the local
Xylem service shop. Always state the serial number of your pump when you contact Xylem,
see Product Description (page 12).
The pump delivers too little or no water
WARNING:
Always disconnect and lock out power before servicing to prevent unexpected startup.
Failure to do so could result in death or serious injury.
WARNING:
Electrical hazard. A permanent magnet motor produces voltage when the shaft is rotating.
The conductors must be insulated.
NOTICE:
Do NOT override the motor protection repeatedly if it has tripped. Doing so may result in
equipment damage.
Cause
Remedy
The impeller rotates in the wrong
direction.
• If it is a 3-phase pump, transpose two phase leads.
• If it is a 1-phase pump:
Contact the local Xylem service shop.
One or more of the valves are set in
the wrong positions.
•
•
•
•
The impeller is difficult to rotate by
hand.
• Clean the impeller.
• Clean out the sump.
• Check that the impeller is properly trimmed.
The pipes are obstructed.
Clean out the pipes to ensure a free flow.
The pipes and joints leak.
Find the leaks and seal them.
Reset the valves that are set in the wrong position.
Replace the valves, if necessary.
Check that all valves are correctly installed according to media flow.
Check that all valves open correctly.

Troubleshooting
Cause
Remedy
There are signs of wear on the
impeller, pump, and casing.
Replace the worn parts.
The liquid level is too low.
• Check that the level sensor is set correctly.
• Depending on the installation type, add a means for priming the pump,
such as a foot valve.
If the problem persists, refer to the Flygt Service Guide on the web or contact the local
Xylem service shop. Always state the serial number of your pump when you contact Xylem,
see Product Description (page 12).
