*Evaporator coil fin material/condenser coil fin material. Contact your local repre- sentative for details about coated fins.

†Weight of 14-in. roof curb. **Single phase/three-phase.

††Rollout switch lockout is manually reset by interrupting power to unit or resetting thermostat.

***Three-phase standard high heat models have heating input values as shown. Single-phase standard high heat models have one-stage heating with heating input values as follows:

580F036 — 115,000 Btuh

580F048,060 — 150,000 Btuh

†††California SCAQMD compliant Low NOx models have combustion products that are controlled to 40 nanograms per joule or less.

NOTES:

1.High-static motor not available on single-phase units.

2.An LP kit is available as an accessory. Kit may be used at elevations as high as 2000 ft. LP kit is not used with Low NOx units.
