*The ZRU140KC compressor is a tandem compressor, consisting of a ZR72KC (25% total capacity) and a
ZR68KC (24% total capacity).
†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.
**Pulley has 6 turns. Due to belt and pulley size, moveable pulley cannot be set to 0 to 1

***The 558F300 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 558F180-300 units have a low-pressure switch (standard) located on the suction side.
