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. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjxn1fec24qyEP3kxqGSpftwruM3p_5Qdf3sL7b0L0xam9rCinenNiIOdGjH_5KGpopzsMdOO1zeR5Gtkh-vWry8_JnBpRIiLBZmalvWgsjF_HORjxU6wpAZgYOnsU57Y_73fc0SRZT8clt/?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. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgZ9qK4lUYpyrf88EXZ6jDKig4AjmAFQyfAy1OtMO3FCCSvIX8i3mW3_DouXAYOJ51cuQ3L25liJio8e6-TLYYE96BREryNIib6MLV97wIomtLBuD5MN6aK7xBuSQND4fTGixtilin2jUz7/?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.
