ELECTRIC HEATER DATA, INDOOR UNITS (cont)
LEGEND
*Values shown are for single-point connection of electric heat accessory and air handler.
†Single-phase motors. All other motors are 3-phase.
NOTES:
1. Electrical resistance heaters are rated at 240 v, 480 v, or 575 v. To determine heater
capacity (kW) at unit nameplate multiply the 240-v, 480-v, or 575-v capacity (kW) by the
factor shown in the table below for the unit voltage.
2. The following equation converts kW of heat energy to Btuh: kW x 3,412 = Btuh.
3. Heater contactor coils are 24 v and require 8 va holding current.
4. Electric heaters are tested and ETL approved at maximum total external static pressure
of 1.9 in. wg.
5. MCA and MOCP values apply to both standard and alternate factory-supplied motors.
