Product review (4 stars): Product works, installation directions are worthless
For the money this is a nice choice.  Looks good and operates well.  However, the installation directions didn't match the product shipped. The directions describe a bottom base plate separated from the motor housing.  This allows you to install the support rods easily from the bottom.  The product shipped had these two pieces welded together, so additional fabrication and a lot of thought had to go into installing this.  I had to drill eight addition holes in the bottom of the motor housing to connect the support rods to it.  This requires you to remove the filters and reach in to attach the nuts to the bolts.  As always, the weight of the unit, fat fingers, small bolts and nuts and gravity are not your friends.
