Interpolation is permissible; extrapolation is not.

All performance is based upon the lower voltage of dual voltage rated units.

Flow is changed to maintain minimum LWT 60° F in cooling and maximum LWT 70° F in heating.

Operation at or below 40° F EWT is based on 15% methanol antifreeze solution.

Table does not re

ect fan or pump power corrections for AHRI/ISO conditions.

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