NOTES:
1. Shaded boxed areas represent KQD units only.
2. MOPD = Maximum Operating Pressure Differential (water pres-
sure differential at unit cannot exceed MOPD or water valve cannot
close).
3. Interpolation is permissible, extrapolation is not.
4. All entering air conditions are 80 F db and 67 F wb in cooling and
70 F db in heating.
5. 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.
6. ARI/ASHRAE/ISO 13256-1 (WLHP application) certified condi-
tions are 86 F EWT, 80.6 F db and 66.2 F wb in cooling and 68 F
EWT, 68 F db and 59 F wb in heating.
