*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, movable pulley cannot be set to 0 to 1
turns open.
††Pulley has 6 turns. Due to belt and pulley size, movable pulley cannot be set to 0 to
open.
***Rollout switch is manual reset.
†††A Liquid Propane kit is available as an accessory.
¶The 48TM028 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 48TM016-028 units have a low-pressure switch (standard) located on the suction
side.
