Notes:
- Optimum performance point, 95°F (35°C) outdoor ambient and (80°F / 27°C dry bulb), (67°F / 19°C wet bulb) indoor conditions. (DOE A 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.
- Superheat °F is at low-side service port, Allow a tolerance of ±3°F (±1.7°C)
- Indoor dry bulb between 70°F and 80°F (21°C and 27°C)
