*Weight of unit does not include variable frequency drive (VFD) barometric relief, or power exhaust. If 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. See Table 2 for more information.

Rollout switch is manual reset.

NOTE: High heat is for 48EJ,EW only.
