I already have the blower, and I was just going to use 2 inch PVC with very heavy 1.5 inch thick closed cell insulation (I have 120 feet of this stuff, long story). The blower matches up with the 2 inch PVC perfectly. How would I match up the PVC (both incoming cold air and the return line) to the tower? Also, where is the thermostat line? Is that in the top of a standard freezer? I was going to use the electronic thermostat listed on your website anyway. Does this override the thermostat in the freezer? Thanks for your help.
