Carrier 30gxr

15% is what it is set at from the factory. On these chillers you will get a lot of nuisance trips at that setting. I always set them at 20-22% and have never had any problems. I have been told by the Carrier 30 series guru that he has no problem at setting them up to 30%. You can only set them up to 30% with latter software.

3/4" and lots of rags if you don't do it right.

3/4" ok also what seals the end is it a o-ring or just a machine seal?

Takes an O-ring. Make real sure the internal checkvalve is holding before you unscrew the plug. Sometimes the plug can be very hard to unscrew the first time.
