THW operating parameters are as follows: Min Source EWT = 20°F; Max Load LWT = 145°F (see application section for design guidelines).
Interpolation is permissible; extrapolation is not.
Operation below 40°F EWT (source) is based upon 15% methanol antifreeze solution.
All performance data is based upon the lower voltage of dual voltage units.
Antifreeze for source water is required for operation in the shaded area and all source EWTs below 40°F.
