Installation and electrical connection
The following installation types are not permitted:
▪ Horizontal installation
▪ Locally applicable accident prevention and trade association safety provisions must be ob-
served.
▪ Observe all regulations for working with and underneath heavy suspended loads.
▪ Make available protective equipment and ensure that the personnel wear the protective
equipment.
▪ Observe the local regulations of sewage technology for the operation of sewage systems.
▪ Avoid pressure surges!
Pressure surges may arise in long discharge pipes with pronounced route profile. These
pressure surges could lead to pump destruction!
▪ Depending on the operating conditions and the pump chamber size ensure the cooling time
of the motor.
▪ To allow the product to be fixed securely and functionally, the structural components and
foundations must be of sufficient stability. The operator is responsible for the provision and
suitability of the structural components and foundations!
▪ Check that the available consulting documents (installation plans, layout of the operating
space, intake ratios) are complete and correct.
DANGER
Risk of fatal injury due to dangerous lone working practices!
Working in pump chambers and tight spaces as well as working where there is a danger
of falling is dangerous work. This work must not be carried out alone! A second person
must be present for safety reasons.
WARNING
Hand and foot injuries due to a lack of protective equipment!
During work there is a risk of (serious) injury. Wear the following protective equipment:
• Safety gloves that protect against cuts
• Safety shoes
• If lifting equipment is used, a protective helmet must also be worn.
NOTICE
Use only technically faultless lifting equipment!
Use only technically faultless lifting equipment to lift and lower the pump. Make sure
that the pump does not jam during lifting and lowering. Do not exceed the maximum
bearing capacity of the lifting equipment! Check that lifting equipment is functioning
properly before use!
▪ Prepare operating space/installation site as follows:
– Clean, cleaned of coarse solids
– Dry well
– Frost-free
– Decontaminated
▪ If toxic or suffocating gases build up, immediately take countermeasures!
▪ Attach the lifting gear to the attachment point using a shackle. Only use technically ap-
proved lifting gear.
