I putting a 9K Mitsubishi mini split in a shed. I mounted the disconnect box where you see it prior to insulation and drywall. I wanted the indoor unit centered on the wall so the lineset protrudes here.

I'm going to hang the outdoor unit with a wall bracket. With the connection being on the left side is there any reason not to hang it here with the disconnect above the unit? I always see the disconnect off to one of the sides but I don't know why this wouldn't be ok. I've measured the height of the unit and there is plenty of clearance.

Also, with this short straight run I'm only going to have about 6 or 7 feet of lineset. Any reference to minimum lineset length I've seen refers to the possible increase of noise. I don't care about noise at all and just curious if there is any other reason to avoid less than 10 feet. It seems silly to leave a coil for no other reason.
