i am a big fan of the tv drama 'House'...does that qualify me to perform surgery? having a 1/2 hour class to get a piece of paper is not the same as being qualified to work in this industry.

sounds to me like one of support springs (internal to the compressor) broke...but why? install your new compressor and it may happen again because you are not qualified to understand the intricacies of how it really works...not just understanding the basics.

adding service valves and filters changes the game a whole lot. this doesn't mean that it can't be done and still work, but how much extra refrigerant are you going to add VERSUS how much should you add? if you got in touch with Copeland tech support, they will not talk to you about your SYSTEM, they would only tell you about the model number of the compressor (which you seem to already know) and what capacitor it takes, etc. wherever you bought the compressor is who you need to talk to about technical support, however, i suspect they don't know jack about it anyway. the companies that represent and sell Copeland products (properly) in the Midwest wouldn't have sold it to you anyway....well, except for 1 very large and nationally known company. they would sell it to you, but they don't know jack about anything in this industry except how to take money from anyone.
you need to call a reputable company in your area. it will be faster and cheaper...i know you think that it won't be cheaper, but in the long run, it will be.
good luck.
