▪ Protect the pump from direct sunlight and heat. Ex-
treme heat can cause damage to the impellers and the
coating!
▪ Impellers must be turned by 180 ° at regular intervals
(3 – 6 months). This prevents jamming of the bearings
and renews the lubrication film of the mechanical seal.
WARNING! There is a risk of injury due to edges on
the impeller and suction port!
▪ Elastomer parts and the coating are subject to natural
brittleness. Contact customer service if the pump must
be stored for more than 6 months.
After storage, remove any dust and oil from the pump
and check the coating for damage. Repair damaged
coatings before further use.

Installation and electrical connection

6.1

Personnel qualifications

▪ Electrical work: Electrical work must be carried out by a
qualified electrician (in accordance with EN 50110-1).
▪ Installation-/dismantling: The technician must be
trained in the use of the necessary tools and mounting
materials for the relevant construction site.
6.2

Installation types

▪ Vertical stationary wet well installation with suspension
unit
▪ Vertical portable wet well installation with pump sup-
port foot
The following installation types are not allowed:
▪ Dry well installation
▪ Horizontal installation
6.3

Operator responsibilities

▪ Observe locally applicable accident prevention and
safety regulations of trade associations.
▪ Observe all regulations for working with heavy loads
and under suspended loads.
▪ Provide protective equipment and ensure that the pro-
tective equipment is worn by personnel.
▪ Observe local sewage technology regulations for the
operation of sewage systems.
▪ Avoid pressure surges!
Pressure surges can occur in long discharge pipelines
with steep terrain. These pressure surges can lead to
the destruction of the pump!
▪ Ensure the cooling time of the motor depending on the
operating conditions and the size of the pump cham-
ber.
▪ Structural components and foundations must be of
sufficient stability in order to allow the device to be
fixed securely and functionally. The operator is re-
sponsible for the provision and suitability of the struc-
tural component/foundation!

DANGER
Potentially fatal danger due to dangerous
autonomous work!
Work in chambers and narrow rooms as well as work
involving risk of falling are dangerous work. Such
work may not be carried out autonomously! A
second person must be present for safety reasons.
WARNING
Hand and foot injuries due to lack of protect-
ive equipment!
Danger of (serious) injuries during work. Wear the
following protective equipment:
• Safety gloves against cuts
• Safety shoes
• Safety helmet must be used if lifting equipment
are used!
NOTICE
Only use lifting equipment in a technically
sound condition!
Only use lifting equipment in a technically sound
condition for lifting, lowering and transporting the
pump. Ensure that the pump does not become
jammed during lifting and lowering. Do not exceed
the max. permissible bearing capacity of the lifting
equipment!
NOTICE
Emerging of the motor during operation
If the motor emerges during operation, the specific-
ations for "Operating mode non-immersed" must be
complied with!
To ensure that the motor is cooled during continu-
ous duty, the motor must be immersed completely
before switching it on again!
▪ Prepare operating space/installation location as follows:
– Clean, free of coarse solids
– Dry well
– Frost-free
– Decontaminated
▪ Take immediate countermeasures if there is a build-up
of toxic or suffocating gases!
