On a low level, everything is fine. But when i put it on high or medium, the brackets of the blades very slightly scrape against the motor housing on one side. Perhaps my ceiling or the fan box is not completely level. What can I do to have that side lowered?
I have a Harbor Breeze New Haven model NH52ABZ5C.

thanks
