Superheat chart for 410a

An R410a and R22 charging calculator or the "Non TXV Charging Guide" are required to determine the target total superheat. Because these systems do not "control superheat" it is critical that the airflow be as close to possible to correct prior to charging as the system will be charged to the airflow.
