STEP 4 - Measure the liquid line temperature _ <br /> and pressure at the outdoor unit's service valve. <br /> Measured Liquid Line Temp = ° F <br /> Liquid Gage Pressure = PSIG _ <br /> Final Subcooling Value= ° F <br /> 000 <br /> STEP 5 - Use the final subcooling value, refriger- Table 14.2 <br /> ant temperature and pressure from STEP 4, to <br /> determine the proper liquid gage pressure using R-410A REFRIGERANT CHARGING CHART <br /> Table 14.2.
