Interpolation is permissible; extrapolation is not. All performance is based upon the lower voltage of dual voltage rated units.

Flow is controlled to maintain minimum LWT 70° F in cooling and maximum LWT 65° F in heating.

Operation at or below 40° F EWT is based on 15% methanol antifreeze solution. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.

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