It’s not a DIY unit per say…
It is precharged but needs to be vacuumed down before charging. The DIY ones seem to be a premium for pre vacuumed lines.
It is a Senville off of Amazon. They don’t like the DIY installs as it will break the warranty. But the price was good and I will take the chance. I think there are really only two or so makers of the mini splits.
All I need to get is a cheap vacuum pump and manifold set.
