*Values only. No single point kit available.
NOTES:
• Electric heater BTUH - (heater watts + motor watts) × 3.412 (see airflow table for motor watts.)
• Supply circuit protective devices may be fuses or “HACR” type circuit breakers.
• Motor load is included in single circuit or circuit 1 of multiple circuits.
• Heater loads are balanced on 3 phase models with 3 or 6 heating elements only.
• Electric heater kits are not permitted for use with 115 volt air-handlers (A voltage).
• J Voltage (208/240V) single phase air-handlers are designed to be used with single or three phase 208/240V electric heaters. To connect 3
phase power to the air handler terminal block, bring only two leads to terminal block, cap, insulate, and fully secure the third lead.
• Do not install 480V electric heaters in 208/240V air-handlers.
• Do not install 208/240V electric heaters in 480V air-handlers.
• If the heater kit is listed under both single and multiple circuits, the heater kit is shipped from factory as multiple circuits. For single phase appli-
cations, Jumper bar kit RXBJ-A21 and RXBJ-A31 can be used to convert multiple circuits to a single supply circuit. See Section 6.2 for details.
