Revision

[1] Variable-speed motor option not available in some unit sizes and some slab numbers; see price sheet for availability [2] Multi-position air handlers will have factory installed horizontal drain pan on right side. [3] Hot water pump voltage will match the voltage of the unit [4] Electric heat kits not available for 120V, 60 Hz models [5] Hot water models only available in 120V Notes: Horizontal Drain Pan Position for slant coil models indicate that the opposing side of the cabinet is side air return capable. All Air Handlers with slant coils can be field converted to allow for either left or right side air return. Approved in Commonwealth of Massachusetts.
