Another thing to check is the wiring thickness. For air conditioner you should use 4.0mm. For typical 13A socket circuit, they would use 2.5mm thick wiring, but sometimes 4.0mm.

I guess if your wiring is 4.0mm, you should be able to convert it to dedicated air conditioner wiring.

But I am only guessing, I am not an electrical engineer nor a certified electrician. I am just giving opinion based on my experience reading standards.
