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.
†The 559F300 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 559F180-300 units have a low-pressure switch (standard) located on the suction side.
