†ARI/ASHRAE/ISO 13256-1 (WLHP applications) certified conditions are 86°F EWT, 80.6°F DB / 66.2°F WB																	Rev: 01/07/07JH
EAT in cooling and 68°F DB / 59°F WB EAT in heating.
Interpoaltion 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

See performance correction tables for operating conditions other than those listed above.

Operation below 60°F EWT requires optional insulated water circuit.

Operation below 40°F EWT is based upon 15% antifreeze solution.
