Why would you pump down the system? Why not just isolate the compressor instead of hoping you can change the control out fast enough. If it's a semi-hermetic it has isolation valves....just wondering.[/QUOTE]

True... but unless it's a service valve with two ports (which I do see occasionally) I would add one else where. Service valves with one port and a control line attached to them are prone to leak. The packing on the stem is not very reliable left open. Most manufactures will use a two port valve or place one elsewhere.

True....but how come the two of us are just speculating...where's CY?
I usually see the pressure controls attached to the body of the compressor. So isolating the compressor is the way to go and the service valves are closed except for service.
