NOTICE
Use only properly functioning lifting equipment!
Use only properly functioning lifting equipment to lift and lower the pump. Ensure
that the pump does not become jammed during lifting and lowering. Do not exceed
the maximum bearing capacity of the lifting equipment! Check that lifting equip-
ment is functioning properly before use!
▪ Prepare the operating space/installation location as follows:
– Clean, free of coarse solids
– Dry
– Frost-free
– Decontaminated
▪ Take immediate countermeasures if there is a build-up of toxic or suffocating gases!
▪ Use the handle for lifting, lowering and transporting the pump. Never carry or drag the
pump by the connection cable!
▪ It must be possible to attach the lifting equipment safely. The storage place and the
operating space/installation site must be accessible by the lifting equipment. The set-
down location must have a firm surface.
▪ Attach the lifting gear to the handle using a shackle. Only use lifting gear which has
been technically approved.
▪ The laid connection cables must enable safe operation. Check whether the cable cross-
section and the cable length are sufficient for the selected installation type.
▪ The corresponding IP class must be observed when using switchgear. Install the
switchgear in an overflow-proof position and away from potentially explosive atmo-
sphere areas!
After a storage period of more than 6 months, turn the impeller prior to installation.
