Just put a new compressor in and recharged the system.

After 24 hours, provided the box has not been opened, you should have  low side running pressure of 2-3 p.s.i.

Ordinarily, we weigh the charge prior to installing, since the exact amount is stamped on the model number sticker. This takes all the guess work out of it later, especially if you have a restriction somewhere that will distort the pressure readings. This may not be rocket science, but it is a science.

Thanks for the Info. I'm more familiar with auto ac and home ac system. Was a little surprised how low the low side pressure was running. unit is up and running well. again thanks for the info.
