14* Ratings are net values reflecting the effects of circulating fan heat. Supplemental electric heat is not included. Ratings are based on:Cooling Standard: 80°F (27°C) db 67°F (19°C) wb indoor entering air temperature and 95°F (35°C) db air entering outdoor unit.High-Temperature Heating Standard: 70°F (21°C) db indoor entering air temperature and 47°F (8°C) db 43°F (6°C) wb air entering outdoor unit.Low-Temperature Heating Standard: 70°F (21°C) db indoor entering air temperature and 17°F (–8°C) db 15°F (11°C) wb air entering outdoorunit.† Outdoor section/indoor section combination tested in accordance with DOE test procedures for heat pumps. Ratings for other combinations aredetermined under DOE computer simulation procedures.‡ In most cases, only 1 method should be used to achieve TDR function. Using more than 1 method in a system may cause degradation in perfor-mance. Use either the accessory Time-Delay Relay KAATD0101TDR or a furnace equipped with TDR.** Requires field-installed TXV, except FC4 and FK4 which have TXV factory installed.COP — Coefficient of PerformanceHSPF — Heating Seasonal Performance FactorSEER — Seasonal Energy Efficiency RatioTC — Total Capacity (Btuh)TDR — Time-Delay RelayTXV — Thermostatic Expansion Valve
