Freezer superheat 404a
Emerson recommends 20° superheat @ the compressor measured 6 inches from in the compressor suction inlet. 5. Filter-driers must be changed at the time of conversion. This is proper air conditioning/ refrigeration practice. a. Solid core driers such as Emerson Climate Technologies, Inc. ADK are compatible with either R-404A/R-407A or R-448A/R ...High superheat, on the other hand, indicates that the amount of refrigerant in the evaporator is low or not sufficient. The evaporator is the part of the system where the refrigerant absorbs heat from the area being cooled. A high superheat can cause the evaporator to freeze and the system to shut down.
