*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 information, see Table 3. **Rollout switch is manual reset.

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