Default L1 and L2

Hello,

I am a homeowner looking to install a new self contained AC unit for my mobile home. I already have everything there from the old unit but the old unit wasn't labeled which wire coming from the breaker box was L1 and L2.

For the new unit it is labeled L1 and L2 and I have a black and white wire as well a ground that are 220V.

Does it matter which wire gets hooked up to L1 and L2? Black or White....

From my online research it showed black normally connecting to L1 but it also showed either wire would work it didn't matter.

Does it matter if so which one? Thanks for the help
