With winter coming soon, I’ve been focusing my attention on getting the heat pump working. First I ran the power from the building to the outside unit.<\/p>\n\n\n\n

\"\"<\/a>
The line-set and communication wire will also need to be connected through the other holes.<\/figcaption><\/figure>\n\n\n\n

Adam came over to help me run the line-set, and we spent some time planning things out. Due to limited access to the inside of the wall, I decided to run it up the wall about 13 ft before passing it through the wall into the attic. However, After some careful measuring, it became clear that the line-set I purchased was too short. I ordered a longer line-set, and listed the shorter one for sale, hoping to recoup most of what I paid.<\/p>\n\n\n\n

\"\"<\/a>
The 25 ft. line-set was only about 2 to 3 ft. short, but the next size up is 10 ft. longer.<\/figcaption><\/figure>\n\n\n\n

Meanwhile I also realized I should have painted the line-set cover before attaching it to the building. I painted the parts that weren’t yet attached in the studio.<\/p>\n\n\n\n

\"\"<\/a>
Painting plastic is always a challenge, as it can take up to a month for the paint to fully adhere.<\/figcaption><\/figure>\n\n\n\n

Then I masked off the already attached parts and painted them in place.<\/p>\n\n\n\n

\"\"<\/a>
Thankfully I have found a readily available spray paint that is nearly identical in color to the siding.<\/figcaption><\/figure>\n\n\n\n

Then I ran the line-set from the attic out to the outdoor unit.<\/p>\n\n\n\n

\"\"<\/a>
I placed a flexible cutting mat from our kitchen around the line-set to ensure it could slide through the hole without getting caught on the sharp steel siding.<\/figcaption><\/figure>\n\n\n\n

Unfortunately, one of the adapters had a small leak, so I just disconnected it and set it aside to fuss with later.<\/p>\n\n\n\n

\"\"<\/a>
It turned out the leaking adapter had a defect in it, and I’m working to get a replacement from the manufacturer.<\/figcaption><\/figure>\n\n\n\n

Next was the task of bending the line-set to fit inside the line-set cover.<\/p>\n\n\n\n

\"\"<\/a>
Bending the stiff 3\/4 in. line was especially challenging to do from atop a ladder.<\/figcaption><\/figure>\n\n\n\n

This proved very difficult since the area at the top which I needed to bend just right could only be accessed with a ladder or by reaching over equipment in the attic.<\/p>\n\n\n\n

\"\"<\/a>
My arms were sore afterward from pushing and pulling so hard and in such awkward positions.<\/figcaption><\/figure>\n\n\n\n

I got it pretty close, and started covering the line-set. However, it quickly became apparent that the line-set barely fit inside, and there was no way I would be able to bend it tight enough to get it to fit at the top.<\/p>\n\n\n\n

\"\"<\/a>
The new line-set cover is 6 in. wide and 4 in. deep, allowing everything to fit comfortably compared to the 4 in. wide and 2 in. deep cover that I tried to make work.<\/figcaption><\/figure>\n\n\n\n

I took a break, ordered a different line-set cover with plenty of room, and moved on to the electrical.<\/p>\n\n\n\n

\"\"<\/a>
Because I ran 10\/3, I ended up with an unused neutral wire.<\/figcaption><\/figure>\n\n\n\n

I wired up the 220v power and the 24v communication wires.<\/p>\n\n\n\n

\"\"<\/a>
I ended up cutting the hole the lines pass through downward and bending the siding in a bit, such that the line-sets rest along a smooth flat surface, rather than a sharp edge.<\/figcaption><\/figure>\n\n\n\n

I then ran the communication wire to the attic inside a waterproof flexible conduit, which will then be concealed in the line-set cover.<\/p>\n\n\n\n

\"\"<\/a>
The connections to the indoor unit are very tight, requiring us to remove some of the insulation from ends of the lines. I’ll have to add some other, less space-consuming insulation to avoid condensation.<\/figcaption><\/figure>\n\n\n\n

Adam came over again a few days later to help get the line-sets connected.<\/p>\n\n\n\n

\"\"<\/a>
Adam used some compressor oil on the connectors to help ensure a quality seal.<\/figcaption><\/figure>\n\n\n\n

We swapped out the leaking connector with an identical one from the not-yet-sold 25ft line-set kit. Now both lines are connected without leaks.<\/p>\n","protected":false},"excerpt":{"rendered":"
