Placement / spacing of mini split indoor units ?

[max_well]

Hey all

I'm looking for suggestions for best placement of 3 separate mini split indoor units (air handler). Each is ~2.5-3 ton, and the dimensions of the space are ~ 16' x' 34' with 12' ceilings. I'm wondering at what height and on which walls the units should be placed for distributing cool air in the space. All 3 spaced evenly on one of the long (34') walls?

With 8' ceilings I've always put the indoor unit high on the wall, with just 6-8 inch clearance; Not sure if this will also to apply our 12' ceiling room. We are planning to use Gavita 1000w lights, which require extra headroom, so lights could be hung as high as 10', I think, depending on the canopy height.
thanks in advance for any insight any advice is appreciated.

If you haven't bought the mini splits yet; with a room that big you could cool it much more efficiently with 4 smaller mini splits (two handlers mounted opposite walls length wise )than with 3 larger ones.
Four 2 ton units, two each opposite each other.
If you mount them all on one side then inevitably the other side will be colder, even if you have fans blow the air around.

Hey Alover
Thx for the advice. Still trying to determine the best configuration and placement for our tall-ceiling room, and the cost benefit of maybe some dual zone units which will have better distribution in the space, but obviously require more install work.
Another question concern I have is the maximum copper line set lengths connecting indoor and outdoor units. I've looked at Fujitsu models, and they have a stated maximum of 161 ft. Im wondering if that is for the combination of the 2 copper lines (ie 80 ft each), or whether each can be up to 161'?
any opinions are welcomed

Yes, it's for the two line sets combined. So 80' per.
