I was leak checking this unit today, and saw a LL drier on the compressor discharge. Was thinking someone screwed up because it's 3/8 and just assumed it was the LL. Also, what can happen with a LL drier on the gas discharge? Will it damage the drier or system in any way? Will the drier do it's job effectively?
Thanks in advance.
