4.7A ELECTRICAL DATA – WITH ELECTRIC HEAT: Single Speed Motor - continued
*Values only. No single point kit available.
NOTES:
•
Electric heater BTUH - (heater watts + motor watts) x 3.414 (see airflow table for motor watts.)
•
Supply circuit protective devices may be fuses or “HACR” type circuit breakers.
•
If non-standard fuse size is specified, use next size larger standard fuse size.
•
Largest 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 heaters only.
•
No electrical heating elements are permitted to be used with A Voltage (115V) air handler.
•
J Voltage (208/240V) single phase air handler is designed to be used with single or three phase 208/240V electric heaters. In the case of connecting 3 phase power to air handler terminal block
without the heater, bring only two leads to terminal block, cap, insulate and fully secure the third lead.
•
Do not use 480V electrical heaters on 208/240V air handler.
•
Do not use 208/240V electrical heaters on 480V air handler.
•
If the kit is listed under both single and multiple circuits, the kit is shipped from factory as multiple circuits. For single phase application, Jumper bar kit RXBJ-A21 and RXBJ-A31 can be used to
convert multiple circuits to a single supply circuit. Refer to Accessory Section for details.
