Does this unit require evacuation and charging of coolant?

Yes, this system will require the refrigerant lines to be evacuated with a vacuum pump during installation, and additional refrigerant may need to be added depending on the length of the line set. The outdoor condenser R5A4S60AKANA comes factory pre-charged with R454B refrigerant for up to a 15-foot line set, so if your installation exceeds 15 feet, the installer will need to weigh in additional refrigerant to achieve the correct charge.
