What is different from the precharged ac lines?

generally speaking, a pre-charged line set is used for DIY mini split installation. 6 steps for split ac installation.

1. Using dry nitrogen pressurizes the line set and air handler to 100-200 PSIG.
2. Using a soap bubble solution spray down all of the flare joints and watch for bubbles to copper  if bubbles are present
3. Tighten the flaring union not or if necessary reflect the copper
4. the technician will use a vacuum pump engages to remove all air and moisture to releasing refrigerant into the air conditioner lines
5. after the vacuum is complete close the manifold gauge value
6. Using an adjustable wrench to remove service valve caps and use an Allen wrench or hex key to fully open both service valves releasing refrigerant into the system the condenser requires

PS: Precharged Line Sets, Is it really actually DIY?
