PHYSICAL DATA — 580F180-300
LEGEND
*Circuit 1 uses the lower portion of the condenser coil and lower portion of the evaporator coils;
and Circuit 2 uses the upper portion of both coils.
†Rollout switch is manual reset.
**The 580F300 unit requires 2-in. industrial-grade filters capable of handling face velocities up to
625 ft/min (such as American Air Filter no. 5700 or equivalent).
NOTE: The 580F180-300 units have a low-pressure switch (standard) located on the suction side.
