A/C installation (II)

Greg (father-in-law) and I started working on the A/C Wednesday afternoon. I had picked up the A-coil, line set and pad in the morning and when Greg got to the house with his truck we picked up the condenser. http://lh4.ggpht.com/_punhvcXlptE/THQXLbemHJI/AAAAAAAAByg/7g4OnnJZukc/%5BUNSET%5D.jpg?imgmax=800The first matter is to cut a hole in the plenum of the furnace. We cut the hole above the burner, then attached some strips of right angle aluminum to rest the A-coil on. You can see the furnace coils are positioned right below the brackets that the A-coil rests on. http://lh6.ggpht.com/_punhvcXlptE/THQYZnPjYpI/AAAAAAAAByk/3n8ZrZgQ1Z0/%5BUNSET%5D.jpg?imgmax=800The A-coil is filled with a gas (nitrogen I think), to ensure that the integrity of the unit is intact when you install it. You use a tube cutter to remove the cap on the end of the bigger pipe coming out of the A-coil, and the gas is released at that point. You set the coil on the brackets and then work on "brazing" the line set to the A-coil.
