Thanks very much, Bill. I‘ve pretty much followed the instructions regarding bleeding air from the manual but only one of my three chiller units has a valve to bleed air. I’ve bled air from both the salt water pump and the circulation pump. However, I believe I have a dearator- see pic. Taking off the cap doesn’t do anything but if I stick a screwdriver into the top, turbulent water/air comes out.
It seems to me that if the salt water circuit is working (it is - water is coming out normally), the compressor should be getting the temp lower than 28C. So I think it‘s likely a low coolant situation. The yard tried the system 3 months ago and it was working but not cooling much. Again, this seems to point to low coolant.
Again, many thanks for your thoughts! Cheers Joerg
