Titan T-1060 Manual Search and Vibration problem...

I have purchased and have this product installed about 6 month ago:

The problem is, all of a sudden, the bottom mount lock got released from a use. So, I thought nothing of it and re-mount the lock and tightened it in. The problem is, for some reason it is lot louder and now it vibrates a LOT. There seems to be two of magnetic half-circular arch thingy which was on the bottom of the sink. I have no idea where it is supposed to go…

I am hoping to find a manual of which I wasn’t able to… So, I was wondering if anyone of you might know where I might be able to find one. My google search fail for me.. sadly.

If any of you even have a suggestion, that would be welcome also.
