*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.

²The 559F300 unit requires 2-in. industrial-grade ®lters capable of handling face velocities up to 625 ft/min (such as American Air Filter no. 5700 or equivalent).

NOTE: The 559F units have a low-pressure switch (standard) located on the suction side.
