NOTES:
➀ Electrical Heat Designation: See electrical heat electrical data for actual heater kW represented by number above.
➁ Electric Heater: BTUH - (heater watts + motor watts) x 3.412 (see airflow table for motor watts).
➂ The air handlers are shipped from the factory with the proper indoor coil installed, and cannot be ordered without a coil.
➃ Electric heat elements are field-installed items.
➄ The air handlers do not have an internal filter rack. An external filter rack or other means of filtration is required.
