*Evaporator coil fin material/condenser coil fin material.
†Rollout switch is manual reset.
**Requires the accessory controls upgrade kit.
††Weight of 14-in. roof curb.
Low-heat weight/high-heat weight.
¶Circuit 1 consists of lower portion of condenser coil and lower portion of evaporator coil, and Circuit 2 is the upper
portion of both coils.
***The 579F300 unit requires 2-in. industrial-grade filters capable of handling face velocities of up to 625 ft/min.
NOTE: The 580D036-150 units have a loss-of-charge/low-pressure switch (accessory) located in the liquid line. The
579F180-300 units have a low-pressure switch (standard) located on the suction side.
