strong and rigid enough to support the
weight of the equipment and to
withstand the forces that occur during
operation.
Make sure that the pipe system of the plant is
clean.
Make sure that the equipment is free from
foreign matter.

Furthermore, if the equipment is installed with the
handwheel upside down, dirt can accumulate in the
bellows.
When mounting the equipment make sure that
the handwheel is on top!
Make sure that the flow arrow matches the
direction of the fluid flow in the pipe.
