DANGER
Magnetic field.
Risk of death for persons with cardiac pacemaker, metallic implant or neurostimulator.
► Under no circumstances may persons with cardiac pacemakers, metallic implant or
neurostimulator perform work on the pump/pump unit.
WARNING
Danger of crushing when assembling motor and pump.
When the motor approaches the pump, high magnetic forces can produce sudden collisions and thus
injuries to hands or fingers.
► Two persons are required for the assembly.
► Use suitable hoisting equipment (for example chain hoist).
► Carry out assembly in the vertical position as far as possible.
► Fixate the pump with suitable measures.
► When the motor approaches the pump, ensure that hands/fingers are not positioned between mo-
tor and pump.
