READ FIRST BEFORE YOU CONTINUE
Re-Sealing the Tropic Air ® Blower discharge cavity Reassembling the discharge cavity.. don't forget the wires...
Once the assembly of the motor to the housing is complete, it is prudent to reseal the lower blower cavity with silicone sealant.  Without it, this thing would probably whistle so loud that it would drive neighbors crazy 3 blocks down.
Assembly complete, wires threaded, now install the screws  
Now, I carefully thread the three blower motor wires through the access hole to the connection box, and pull them in a reasonable amount todouble check for wire interference with the armature ensure that air movement won't cause interference between the rotating armature, and the wires inside.  This must be done simultaneously with assembling the blower housing.  Afterwards, it's a good idea to make a visual check through the blower exhaust to ensure that none of the wires are liable to make contact with the rotating armature.  Everything done?  Now re-install the through bolts and tighten the nuts down.
Reusing the noise reducing foam
With the discharge assembly complete, I re-use the foam strips and install them with silicone.
foam reinstalled.. 
It is important to try to re-use the foam, simply because it is the most important part of noise reduction.  The blower will work without it... only it'll be a bit louder.
check the foam here to ensure it's secure in the housing assembly of the blower is complete.
Make a judicious inspection of the noise reducing foam in the blower intake cap.  If it's loose or coming apart, go ahead and remove and replace it, or re-install it using silicone adhesive.  Finally, re-install the screws from the suction part of the housing.
