If below the chart value remove refrigerant. If below the limit line, remove refrigerant. Example (Using the 12,000 Btuh cooling chart): 1. Suction pressure is 65 psi. which equals 38° F on The R-22 Scale of the Low- Side gauge. 2. Suction line temperature taken at the unit is 70° F. 70° F minus 38° F equals 32° F superheat. Instructions: 1. Measure suction pressure and determine evaporator-refrigerant temperature on R-22 scale of low-side gauge. 2. Measure suction-line temperature on suction li
