Hi,
recently I was called to a small chiller unit from Airwell (CLS302) It is charged with R407C.
It has been build 2006 and in 2007 they had a leak in one of the evaporators. They have changed the evaporator and compressor.
Now my problem, I still measure a leak with a electronic leak detector. Is there a way to clean out the piping if yes what product/method should I use?
Or should I -out of precaution - recover the unit and add a nitrogen charge to leak test the unit once again to make sure there is no leak and leave it with that ?
Kind regards
