In the United States, running for political offic...Using the temperature rise method (CFM = KW (Volts X Amps) X 3.413 divided by (Temp rise X 1.08)), check the airflow. Using the manufacturer's coil specification sheets, confirm the pressure drop across coils. The airflow measurement is used to find the evaporator load, so it must be accurate. Check the system operating pressures.Continue the process until the system has been determined to be leak-free. Connect the vapor-line and liquid-line pressure taps to a vacuum pump and micron meter. This step is also almost always omitted. Evacuate the refrigerant lines and indoor coil to at least 350 microns. Close off the valve to the vacuum pump and observe the micron meter.How to Use a Refrigerant Gauge Set STEP BY STEP to Read Subcooling for R-410A!This is how to Use the Gauge set in order to check an R-410A refrigerant Charge...Outdoor ambient temperature.
