    Bought the head units with the outdoor condensing unit. The website was kind enough to make sure that I knew that I had 3/8 and 5/8 lines for the fourth wall unit.

    However, upon your completion of the job, we noticed that the plug-ins for the unit are not the same as the fifth plug-in for the line set is 1/2 and 1/4. Being that this is an out of town job in a small town with no hardware store we had to leave and go out of our way to find suitable parts to complete the job
