Twin SANCO2 Plumbing Diagram

a twin sanco2 system changes the plumbing only around the sanco2 heat pumps calculate line effective length add up the length of 1⁄2” and 3⁄4” pipe from heat pump to pod/heat pumps, and add 1⁄2 ft per short radius elbow (large radius elbows don’t count) this should be 60' or less l effective(ft) = l 3/4 + 0 5 (qty 3⁄4” elbows) + l 1/2 + 0 5 (qty 1⁄2” elbows) the effective lengths for each heat pump should be maintained within 10% of each other install swing check valves on cold side of each 1⁄2” heat pump line install flow meter near pod connection a (on hp cold line) on the common 3⁄4” line, oriented to measure flow out of the pod install thermistor t6 on the common heat pump hot line attach thermistor to pipe using foam tape or tie down with zip tie insulate the thermistor generously to ensure it is not affected by air temperature
