*Weight of unit does not include variable frequency drive (VFD), barometric relief, or power exhaust. If a VAV unit (a VFD is installed), add the VFD weight in the table at right.

²Evaporator coil ®n material/condenser coil ®n material.

**Sizes 024-034: Circuit 1 uses the lower portion of condenser coil, Circuit 2 uses the upper portion. Sizes 038-048: Circuit 1 uses the left condenser coil, Circuit 2 the right. All units have intertwined evaporator coils.

²²Motor and drive shown will deliver approximately 2.5 in. wg net external static. For more drive information, see Table 2.

NOTES:

1.See Table 2 for optional evaporator fan motor data.

2.Sizes 038 and 048 are 50EJ,EW units only.
