Just a good tip I was shown years ago! The sales order on a York OptiView panel has a lot of good information in it. I was setting up the flow for this chiller as the customer installed new balancing valves on the condenser side. You can use the pressure drop ( which is in feet of head ) and convert to PSID across the chiller. For example the 25.7 / 2.31 = 11.12 PSID. So I set up the pressure drop to 11 across the condenser.
