Message	The proper technique is.. 1) Pull the system into Vacuum.. This will also Trip the Low Pressure Switch, and Prevent the AC Compressor from running ( Safety ) 2) Start adding Refrigerant to the Low Side of the System. As the Pressure in the low side starts getting around 20 PSI, the LP Safety switch will allow the compressor to start running and push the Refrigerant to the High Side. 3) Charge untill sight glass is clear, or untill proper amount if charge is installed. If your compressor is being held off by the Low Pressure Switch, than you are not getting enough charge into the Low Side of the System. Cj
