**The 48TJ028 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).

*Circuit 1 uses the lower portion of condenser coil and lower portion of evap- orator coils; and Circuit 2 uses the upper portion of both coils.

tRollout switch is manual reset.

NOTE: The 48TJ016-028 units have a low-pressure switch (standard) located on the suction side.
