4. Orifice - inside the high pressure hose fitting where it connects to the condensor.
That's l messed with but that should be all you need.
Thanks for the info. This will help greatly when I start looking at it this weekend.
Do you know if the pressure switches have a valve at the connection? Can I remove the switch without evacuating the system?
