WARNING
!
The device may only be mounted and commissioned by qualified personnel!
Qualified personnel within the meaning of this operating manual are persons who are
familiar, with assembly, commissioning and operation of this product, and have the
required appropriate qualifications for this activity.
WARNING
!
For assembly and disassembly of the linear unit, the pipes where the valve is installed
on must be depressurized. If the actuator is removed from the linear unit, the position
of the valve stem won't be fixed anymore and will be lost due to the linear units non
self-locking property.
WARNING
!
The linear unit has end stops on both end positions. Do not move against the end stops in
electrical operation. The end limits of the actuator must be set accordingly. Never bring
the valve cone with excessive force in the CLOSED position. This can damage the high
quality sealing edges.
