    Confused Coil Connections

    First of all I would like to thank everyone for this site. This is absolutely an amazing site and such a powerful tool as I strive to learn the industry.

    I have a question I've been pondering as I do take-offs.

    I'm looking at the Carrier submittals/product data for newer ACCU and looking at the coil connections. For the one I'm looking at - it lists Suction = 1-5/8 and Liquid = 5/8. Are these sizes on the submittal sheet in Nominal Dia. or OD? If OD, I assume to connect 1-1/2 and 1/2 respectively Nominal Dia. Copper piping to the coil?

    Thank you so much in advance.

    Talking different thickness in copper be careful

    refrigeration air conditioning pipes are thcker... nitrogenized or made clean... plumbing pipe not as clean not as thick refrig costs more but will hold out in long run... cleanliness in our trade is mandatory that said water is our enemy it will csrew up everything....good luck
