HVAC Technician Daikin Heat Pump Lineset

Daikin unit single floor mount head unit. Wet lineset. Cleared with Nitrogen already. Fieldpiece or sim vac unit required and digital manifold. Got Down to 1100 microns took forever and it was slowing. Tech told me honestly to call someone to work on it on their own time since it could take 3-4 hours and it would help someone out. It's a long line set. May need to disconnect from head unit and compressor, clear head unit (it is several feet above compressor in elevation about 100 feet away) clear lineset itself, then clear compressor hook it all back together and clear the system per normal and then recharge with 410A. Was working fine before line blew its flare connection to compressor. Likely a poor flare by installer.
