5.3. Installation
DANGER of falling!
When installing the pump and its accessories,
work is sometimes performed directly at the
edge of the basin or sump. Carelessness or
wearing inappropriate clothing could result
in a fall. There is a risk of fatal injury! Take all
necessary safety precautions to prevent this.
The following information should be taken into
considerationwheninstallingthepump:
• Thisworkmustbecarriedoutbyaqualied
person and electrical work must be carried out by
an electrician.
• Thecollectortankmustbeclean,freeofcoarse
solids,dry,frost-freeand,ifnecessary,de-
contaminated. It must also be suitable for the
particular pump.
• Whenworkinginsumps,asecondpersonmust
be present for safety reasons. If there is a risk of
poisonousorasphyxiatinggasesforming,the
necessary precautions must be taken.
• Depending on the ambient conditions in opera-
tion,theunitplannermustselectthesumpsize
and motor cooling time accordingly.
• Ensurethatliftingequipmentcanbetted
withoutanytrouble,sincethisisrequiredfor
assembly and removal of the pump. It must be
possible to reach the pump safely in its operating
and storage locations using the lifting equip-
ment.Themachinemustbepositionedonarm
bearingsurface.Fortransportingthepump,the
load-carrying equipment must be secured to the
liftingeyeletsprovided.Whenusingchains,they
must be connected with a shackle to the lifting
eyeletsorthecarryinghandle.Liftinggearmust
be technically approved.
• Power supply cables must be laid out in such
a way that safe operation and trouble-free
assembly/dismantling are possible at all times.
The pump must never be carried or dragged by
thepowersupplycable.Checkwhetherthecable
present is long enough for its cross-section and
its installation type.
• Whenusingswitchgears,thecorresponding
protectionclassmustbeobserved.Ingeneral,
switchgears must be installed outside potentially
explosive areas in such a way that they are pro-
tectedfromooding.
• Structural components and foundations must
besufcientlystabletoallowtheproducttobe
anchored securely and functionally. The operator
or the supplier is responsible for the provision of
the foundations and their suitability in terms of
dimensions,stabilityandstrength.
• If the motor housing is to be taken out of the
uidduringoperation,theoperatingmodefor
non-immersed operation should be followed.
To keep dry motors sufciently cooled in S3
mode, they must be ooded completely before
being switched back on if the motor has been
taken out of the uid!
• Never let the pump run dry. The water level must
neverfallbelowtheminimum.Therefore,we
recommend installing a level control system or a
dry-running protection system where there are
great variations in the level.
• Useguideanddeectorplatesfortheuidintake.
Ifthewaterjetreachesthesurfaceofthewater,
airwillbeintroducedintotheuid,whichcan
accumulate in the pipe system. This can result in
inadmissible operating conditions and to deacti-
vation of the entire system.
• Checkthattheavailableconsultingdocumen-
tation(installationplans,layoutofthecollector
tank,intakeratios)iscompleteandcorrect.
• Pleaseobserveallregulations,rulesandlegal
requirements for working with and underneath
heavy suspended loads. Wear appropriate protec-
tive clothing/equipment.
• Please also observe the applicable national acci-
dent prevention regulations and trade association
safety provisions.
5.3.1. Maintenance work
Afterastorageperiodofmorethan6months,the
following maintenance work must be carried out
beforeinstallation:
• Rotate impeller
• Checkoillevelinthesealingchamber
Rotate impeller
1. Positionthepumphorizontallyonarmsurface.
Make sure that the pump cannot fall over and/
or slip.
2. Carefullyandslowlyreachintothehydraulics
housing from below and rotate the impeller.
BEWARE of sharp edges!
Sharp edges can form on the impeller and
hydraulic opening. There is a risk of injury!
Wear the necessary protective clothing, such
as protective gloves.
Check oil level in sealing chamber
The sealing chamber has a hole for draining and
llingthechamber.
1. Positionthepumphorizontallyonarmsurface
with the screw plug facing upward.
Make sure that the pump cannot fall over and/
or slip.
2. Unscrewthescrewplug(seeFig.4).
3. The oil should reach up to about 1 cm below the
hole for the screw plug.
4. Ifthereisnotenoughoilinthesealingchamber,
topitup.Todoso,followtheinstructionsunder
“Oilchange”inthe“Maintenanceandrepair”
chapter.
5. Cleanthescrewplug,replacethejointring,if
necessary,andscrewitbackin.
5.3.2. Portable wet well installation
The pump can be positioned anywhere in the
operating space using the built-in pump foot.
