*Refer to Systems Index Table on page 21.
†The 619C024 unit must be field configured to an 018 size unit by
changing the motor speed fan tap plug. Refer to Installation Instruc-
tions for more details.
NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The SHG is based on 80 F edb temperature of air entering indoor
coil.
Below 80 F edb, subtract (corr factor x cfm) from SHG.
Above 80 F edb, add (corr factor x cfm) to SHG.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).
