*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.
†Evaporator coil fin material/condenser coil fin 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.
††Motor 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 evaporator fan motor data.
2. Sizes 038 and 048 are 50EJ,EW units only.
