And just to clarify I do have a factory warranty. When I purchased from EComfort they provided the names of three Mitsubishi trained/certified installers in my area. I used one of them to finalize my rough install. I was provided a receipt from the installer stating they installed the unit. I went online and registered my warranty with Mitsubishi. Part of the registration process is to tell them who did the install. About a week later I received an email from Mitsu stating that my warranty has been registered and is in place. If I ever have a problem in the future I will call the same people that did the install. So my 5 year parts and 7 year compressor warranty are in fact good. If you think about it I did the no brainer/grunt work that the installer I'm sure gets no joy over to do.

1.I installed the outside unit on the wall mount brackets. Just have to make sure it is level in both directions and secure.
2.I installed the inside wall bracket and drilled the hole in the wall that the copper lines/drain/low voltage wiring goes through. Again just make sure it is level and secure.
3.I installed the vinyl exterior chase that the lines/drain and wiring run through. A blind man can do this.
4. I ran the 220v power from the breaker box to the outside disconnect box. This is not rocket science either but should not be taken lightly. But plenty of info online regarding wire size for xxx amount of run. I ended up using 10 gauge wire and I ran it all in metal conduit.

I had all the bits and pieces neatly layed out for the installer, he actually thanked me for being so prepared. He checked out my work and said it was VERY professional and easily passed code.

That's how you do a rough install and still maintain the factory warranty.
