Single-phase 15- or 20-KW heaters are wired for dual-circuit operation. The optional single-circuit kit may be field-installed in units with a 15- or 20-KW single-phase fused heater for single-circuit operation. tfCB = circuit breakers. ++Used for right-angle refrigerant connections to the coil (or optional 510B Coil). ***Wire sizes and lengths are based on copper conductor at 86°F (30°C) ambient temperature and ampacity shown in table. Insulation must be 90°C on conductor used between the disconnect switch and the heater and at least 75°C on the conductor used between the disconnect and the service panel. If other than copper conductor is used, or if ambient temperature is above 86°F, determine wire size for ampacity shown and the National Electric Code. Wire lengths shown are measured one way along the wire path between the disconnect and service panel for minimum 2% voltage drop. tttUse piston size shipped with outdoor unit.
