*The ZRU140KC compressor is a tandem compressor, consisting of a ZR72KC (25% total capac- ity) 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, movable pulley cannot be set to 0 to 11/2 turns open.

††Pulley has 6 turns. Due to belt and pulley size, movable pulley cannot be set to 0 to 1/2 turns open.

***Rollout switch is manual reset.

†††A Liquid Propane kit is available as an accessory.

¶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 580F units have a low-pressure switch (standard) located on the suction side.
