• Supply circuit protective devices may be fuses or “HACR” type circuit breakers.
• Largest motor load is included in single circuit and multiple circuit 1.
• If non-standard fuse size is specified, use next size larger standard fuse size.
• J Voltage (230V) single phase air handler is designed to be used with single or three phase 230 volt electric heaters. In the case of connecting 3-phase power to the air handler terminal block
without the heater, bring only two leads to the terminal block cap, insulate and fully secure the third lead.
