Finally got around to finishing the job last night. Wish I had taken pictures of my vacuum setup but when its 90 degrees and youre pouring sweat while 10ft in the air, I decided not to ad any steps.
Turned the unit on at 11pm last night the room was 91. Went to sleep and the room was 68 this morning
So here steps involved from my last post.
Mount the outside unit on the bracket. 88lbs 10ft in the air with just an extension ladder was not fun or safe
Run conduit outside and up the wall to the water tite disconnect. House is 2 rows of 4"
brick with a 1" air gap between the rows. I only had a 1"x16" sds bit which was just a bit too small for 3/4 pvc conduit. Had to bore the hole out for a while to get it big enough.
Next was the lineset running. My unit came with 25ft of linesets which were too long so I had to cut them down. I bought the yellow jack flaring tool 60278.
Cut, debur, nylog everything, then flare
The tool had great reviews but I had less than a great experience with it. When screwing down the flaring cone, its easy to go just a bit too far. This results in a ridge down the face of the flare which will cause a leak. I didnt notice this ridge until my last flare. Needless to say I was very frustrated.
There are other flaring tools available that have a clutch in them. Takes the guess work out of how much to tighten.
I remade 3 of my 4 flares and hooked up my nitrogen setup and pressure tested to 300 PSI. I checked all connections and found no leaks.
In hindsight, I wish I had left the returning line flare off and purged the system with nitrogen for a few minutes. I believe I could have gotten a better vacuum on the system.
Then I hooked up my vacuum pump micron gauge. I got the system down to 325 microns and valved off the pump. It rose to 525 and stopped. This was good enough for me. Plus is was 1030pm on a sunday night.
The outside unit is very very quiet and the inside unit is about as loud as my refrigerator. I have the temp set to 75 right now and the first floor is very comfortable.
The inside unit display shows the compressor frequency. There are 5 bars that can illuminate 1-5. I think that more load is more bars? Since this is an inverter based unit??
