Anyone familiar with the Vector 1550 with the scroll compressor and economiser. Only had a brief look at a running unit and though it was strange to see the liquid line being cooled low enough to give it frost after the heat exchanger. +5C ambient, -18C box temp.

Thanks

Had a liquid line frosting years ago due to the suction crushing the the liquid line in the heat exchanger

Thanks redroge. Im guessing when the economiser is in play it only drops the liquid temp maybe 5-10 degrees when working correctly.
