*Evaporator coil fin material/condenser coil fin material.
†Weight of 14-in. roof curb.
**On 579F180-300 units, 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.
††Rollout switch lockout is manually reset by interrupting power to unit or resetting
thermostat.
\The 579F300 unit requires 2-in. industrial-grade filters capable of handling face
velocities of up to 625 ft/min (such as American Air Filter no. 5700 or
equivalent).
NOTE: The 579F180-300 units have a low-pressure switch (standard) located on
the suction side.
