Rev: 12/12/03 BInterpolation is permissable, extrapolation is not.
All entering air conditions are 80°F DB and 67°F WB in cooling and 70°F DB in heating.
All performance data is based upon the lower voltage of dual voltage rated units.
Operation below 40°F EWT is based on 15% antifreeze solution.
See performance correction tables for operating conditions other than those listed above.
Table does not reflect fan or pump power ISO corrections.
