May also need some of that wire between the indoor and outdoor unit.
But again, depends on what you have.
Never heard of that brand. But this is in the manual you posted.

The bigger the unit the bigger the gauge wire needed. The smallest unit, the 30, needs the smallest gauge wire, at 12.
WG is just a term for wire plus ground.
What model are you installing?
The wire voltage rating should be fine.
All the big box stores sell wire that size.
Just remember, no romex outside. You’ll have to get the appropriate outdoor materials to run the wire in.
