PHYSICAL DATA — 579F180-300
LEGEND
*Circuit 1 uses the lower portion of condenser coil and lower portion of evapora-
tor coils; and Circuit 2 uses the upper portion of both coils.
†Rollout switch is manual reset.
**The 579F300 units 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 579F units have a low-pressure switch (standard) located on the suc-
tion side.
