*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.

5.ARI//ISO 13256-1 (WLHP application) certified conditions are 86 F EWT, 80.6 db and 66.2 F wb in cooling and 68 F EWT, 68 F db and 59 F wb in heating.
