Evacuating mini split in cold weather.
I plan on installing my mini split tomorrow and the weather will be in the 30's. I will be using a core removal tool, micron gauge, and vacuum rated hose. Is it ok to evacuate in cold weather or should I wait for it to warm up? I assume the little moisture would still boil off even if its cold around freezing out?
The condenser is precharged and the evaporator is filled with nitrogen. Line set is about 12 feet so I would just be evacuating the lineset and evaporator.
