condenser mounted higher than evaporator?

Hi, looking at installing a single-zone 24k BTU unit for an outbuilding. Are there any operational issues with mounting the evaporator (inside) approximately 8 feet from ground level, and the condenser (outside) about 6 feet above the evaporator (14 feet from ground level for reference)?

I want to make sure this won't damage the unit and before ordering the unit, see if I need any extra parts to have the unit configured in this condenser high installation.

I reached out via your website contact form. I received a sort of generic canned response about reading the directions, and was told to ask my installer. I half expected this kind of reply, as it was likely a CS person, or an entry-level sales person, responding to the contact form most likely.

Since this is an outbuilding, I plan(hope) to do a DIY install since it's not a critical building installation, thus I don't have an installer to query. I like doing projects like this since I'm pretty handy and have the tools, but this being a more unusual install, I'm just trying not to make assumptions and kill the system from improper install. Just having found this sub on Reddit, I figured I'd ask here and perhaps get a better, more direct, and clearer answer to the question.

On a side note: What is the minimum Line set length the system will operate properly? And what amount, if any, refrigerant needs to be removed for whatever that minimum length operation is?

Thanks
