Questions & Answers
If I only have two areas that need conditioning, but may add a third in the future, is it possible to only have two lines hooked up without causing issues? what are the possible Seer ratings and how are these maximized?

If I only have two areas that need conditioning, but may add a third in the future, is it possible to only have two lines hooked up without causing issues?
Yes, you can leave the extra connection capped until you need to use it. Also, if you are planning to add the third indoor unit eventually, you will want to take that into account when selecting which units to install. You will want to make sure to not maximize the output of the condeser with the first 2 indoor units, otherwise adding the third unit may put excess stres son the condensing unit.
As recommended by an LG representative, running 3 x 8,000 BTU Indoor units will be fine for this condenser.
