Insalled new 3 phase scroll compressor, R22 system.
the old one was rattling and making noise and not pumping.
now the new one runs fine for a minute and starts pumping down and all the sudden the high pressure internal safety valve on the compessor pops. the high side guage is only reading 180 psi at the discharge of the condenser. so this tells me the condenser must be plugged.
i backflushed the condenser with nitrogen today and nothing came out and seemed free from any kind of plug or chunks of anything.
also installed a shrader valve near the discharge of the compressor to check psi there but it sure seems like the condenser is plugged up. i will try running it again later and check the PSI just after the compressor on the discharge side..
any ideas?? i have a bad feeling its going to do the same thing even after i flushed the lines with nitrogen because they sounded clean and nothing came out.????????????????
