34 WILOSE04/2014V05DINA4
English DECOMMISSIONING/DISPOSAL
correctdirectionofrotation,aclockwiserotating
eldmustbeavailable.
The pump is not approved for operation with a
counter-clockwise rotating eld!
6.2.2. If the direction of rotation is incorrect
If the direction of rotation is incorrect for direct
startmotors,2phasesmustbeswapped.Inthe
caseofstar-deltamotors,theconnectionsoftwo
windingsmustbeswapped,e.g.U1withV1and
U2 with V2.
6.3. Level control
Checkthatthelevelcontroldeviceisinstalled
properlyandinspecttheswitchingpoints.Forthe
required information please refer to the instal-
lation and operating instructions for the level
controldevice,aswellastheconsultingdocu-
mentation.
6.4. Commissioning
The pump must have been installed properly as
speciedinthe“Installation”chapter.Thismust
be checked before the system is switched on.
Minor oil leakage in the mechanical shaft seal on
deliveryisnocauseforconcern.However,itmust
beremovedpriortosubmersionintheuid.
Keep out of the pump's work area. No persons
are allowed in the work area during start-up or
operation.
Ifthepumpfallsover,itmustbeswitchedoff
before setting it up again.
WARNING: Danger of crushing!
In portable installations, the pump can fall
over when it is switched on or during opera-
tion. Make sure that the pump is positioned
on a rm bearing surface and that the pump
foot is mounted correctly.
6.4.1. Before activation
• Checkthefollowing,ingeneral:
• Cableguidance–noloops,slightlytaut
• Min./max.temperatureoftheuid
• Max. immersion depth
• Cleanthepipesystemonthepressureside
(hose,piping)–ushwithcleanwatertopre-
vent deposits forming clogging.
• The hydraulics housing must be completely
lledbytheuidandtheremustbenoairin
the housing. It can be vented by suitable vent-
ingdevicesinthesystemor,ifavailable,using
vent screws on the pressure port.
• Checkswitchingpointsoflevelcontroland
dry-running protection systems
• Checktoensureallaccessoriesareproperly
tted
• The following points must also be checked for
wetwellinstallation:
• Cleanthepumpsumpofcoarsecontaminants
• Openallslidevalvesonthepressureside
6.4.2. Switching on/off
The pump is switched on and off using a sepa-
rateoperatingpoint(on/offswitch,switchgear)
provided by the customer.
Duringthestart-upprocedure,theratedcurrent
is temporarily exceeded. After the start-up pro-
cedureisnished,thecurrentmustnotexceed
the rated current again.
Ifthemotordoesnotstartup,itmustbe
switched off without delay. Before switching it on
again,waitforthespeciedstartpauseandmake
sure to rectify the fault.
6.5. Safety rules during operation
Whenoperatingthepump,alwaysfollowthe
locally applicable laws and regulations for work
safety,accidentpreventionandhandlingelec-
trical machinery. To help ensure safe working
practice,theresponsibilitiesofemployeesshould
beclearlyspeciedbytheoperator.Allpersonnel
are responsible for ensuring that regulations are
observed.
Duetotheirdesign,centrifugalpumpshave
rotating parts that are easily accessible. Depend-
ingontheoperatingcondition,sharpedgescan
develop on these parts.
WARNING: Danger of crushing and amputation
of limbs!
Sharp edges can form on the rotating parts in
the hydraulics. These can result in crushing
and amputation of limbs. Never reach into the
hydraulics when the machine is in operation.
The following must be checked at regular inter-
vals:
• Operatingvoltage(permissibledeviation+/-
5%oftheratedvoltage)
• Frequency(permissibledeviation+/-2%ofthe
ratedfrequency)
• Currentconsumption(permissibledeviation
betweenphasesisamaximumof5%)
• Voltage difference between the individual
phases(max.1%)
• Switchingfrequency(seetechnicaldata)
• Avoidairentryintheinlet,adeectorplate
shouldbettedifnecessary
• Minimum water submersion
• Switching points for level control device or
dry-running protection
• Smooth running
• All slide valves must be open.
7. Decommissioning/disposal
• All work must be carried out with the greatest
care.
• Proper protective clothing is to be worn.
• Whencarryingoutworkinbasinsand/ortanks,
the respective local protection measures must be
observed. A second person must be present for
safety reasons.
• Onlyliftingequipmentthatisinatechnically
perfect condition and load-carrying equipment
