Tunze Magnet problems

[nadking]

Hi, I just picked up a used 6100 with 7094 and 6080.5 magnet from a fellow reefer. I am setting it up and was wondering if there is suppose to be some kind of screw that connects the pump to the magnet holder as it seems that mine sways and jolts around quite a bit.
Thanks

There is some freeplay between the magnet holder and the 6080.230 post with hinge, this results in the sway, this sway is worse if you mount the pump upside down, the pump should hang from the arm, not be above the arm. This freeplay was deliberate to allow removal after coralline algae growth. There is a later piece 6200.230 that is more secure, these did not come out as a standard part until the 6101.
