Here's a tip, aside from the one nut touching the cooler, the inside plumbing components don't really need to be taped or even torqued down.  Just thread them on there a couple spins by hand so you can take them apart easily to clean the unit.  Be sure to use stainless steel clamps rather than galvanized, although you might find you don't need clamps at all if your heat rated tubing is tight enough.  If it loosens over time you will have to replace it or start using the clamps.

One of the problems you may encounter is getting too much grain underneath the false bottom.  This can cause problems with draining.  One of the major causes is crushing the grain too finely.  Try not to set your mill below .039.  You can fix this by using a half pound or more of rice hulls which will further filter and channel the grain.  Rice Hulls are needed for most wheat recipes.  Stirring can disturb the bottom causing it to float up and grain get underneath, so when you stir avoid disturbing the False Bottom.  Low mash temperature will make the dough thicker as temperatures drop resulting in poor runoff.  Try to sparge at mash-out temps.  If you get too many grain fragments after you drain,  you can let it cool and settle then rack off the clear stuff with a siphon (leaving the muck on the bottom for further straining), drain through a screen filter, or just pour the clear stuff off through a screen.
