*Optimum performance point, 82 ° F outdoor ambient and (80 ° F dry bulb),( 67 ° F wet bulb) indoor conditions. (DOE B Test Conditions)

Where a dash ( --- ---) appears do not attempt to charge system under these conditions or refrigerant slugging may occur. Charge must be weighed in. Note: Superheat ° F is at low---side service port, Allow a tolerance of ± 3 ° F

Note: Indoor dry bulb between 70 ° F and 80 ° F
