*ARI 320 points (bold printing) are shown for comparison purposes only. These are not certified data points.
NOTES:
1.MOPD = Maximum Operating Pressure Differential (water pres- sure differential at unit cannot exceed MOPD or water valve can- not close)
2.Interpolation is permissible, extrapolation is not.
3.All entering air conditions are 80 F db and 67 F wb in cooling and 70 F db in heating.
4.All performance data is based upon the lower voltage of dual volt- age rated units. See Performance Correction Tables on page 21 for operating conditions other than those listed above.
