Hey guys.
Last week we changed a compressor that was down to earth. Whilst soldering the new compressor in I asked the senior tech if he wanted to purge with dry nitro to stop scaling. He didn't want to. So we got the compressor in and evaced and charged.
then when we ran the system the head pressure wouldnt get over 1000kpa, the compressor made a few noises. Then it stopped pumping, both sides equalized.
so my question, do you think that the compressor being inefficient had anything to do with not purging the system?
