It sounds like you have a couple of problems.First I think you have to much oil in the system and the next thing I would check is the condensor.If the pressure shoots up that quick you may have a blockage in the condensor,it could also be blocked with to much oil.You did not mention just what you are putting this system on and that would be helpfull.
It is a boat refrigeration system with a cold plate the Old York worked just fine with it. How could to much oil get in the system? the Sanden compressor came with oil and the tech put standard 134a gasin and the receiver was new. aAlot of oil came out when I opened the system after he charged it as noted in my last email. So I have evacuated it after putting in the new receiver should I just charge it again and see what happens?? or what
At this point I would drain the condensor and make sure that is does not have any more than an ounce of oil in it.You could also try a flush,with the pressure that high it would seem that there is a restreiction some where and it is usually in the condensor.
if I drain it do I need to put more oil back in or would the new gas be enough? by the way the new gas 134a has syntheic oil is that ok
That is ok just make sure you have a little oil in the condensor.
