When evacuating minimum vacuum level that should be reached is?

Evacuation Process While pulling a deep vacuum, it is impossible to bring the pressure down to 0 microns. We consider 500 microns to be an acceptable deep vacuum level for evacuation. At a deep vacuum of 500 microns, almost all moisture in the system can evaporate and be thrown out of the system.

The three different recovery methods are: vapor recovery; the push-pull method; and the liquid recovery method. In the vapor recovery method, the refrigerant is removed from the HVAC system in a vapor state. The vapor is then condensed into a liquid by the recovery unit and transferred to the recovery cyclinder.

When recovering refrigerant you should only recover the refrigerant into?

Recover the refrigerant into the system's own receiver or storage tank if it has one. It is most efficient to recover liquid first (from the system's liquid line), then vapor. Recovering refrigerant in vapor phase will leave the oil in the system, minimizing oil loss.
