Re: Removing Mini-split A/C-Heatpump systems

said by 49528867:

Move the unit to the new location reconnect the tubing fitting up the high side coupling nice and tight but leaving the low side coupling finger tight, slowly open the high side valve allowing refrigerant to flow into the evaporator to purge the tubing toward the low side through the loose fitting for about 10-15 seconds of flow then make up the low side coupling nice and tight.

I have a mini-split unit at home that was previously at another location before it was given to me. I don't know how the process of removing the unit was done at the old location but the guy that installed it at my place used a vacuum pump to purge all air from the system before he opened the valves. I can't recall if it needed to be recharged a bit. I think it wasn't.

That is the proper way of removing all air and more importantly moisture from a system that has been opened.
