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.
Interpolation 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.
