COMBINATION RATINGS
i 38GR006 and 40BA009
Ratings Notes
1. Direct interpolation is permissible. Do not
extrapolate.
2. SHC is based on 80 F db temperature of air
entering evaporator coil.
Below 80 F db, subtract (corr factor x cfm)
from SFIC.
Above
80 F
db, add (corr. factor
x
drn) to
SHC.

5. Combination ratings are based on a 2 F line
loss. For a close-coupled system (less than
15 ft),
add 2%
to ratings. Piping sizes in Table
13 are based on 2 F line loss. All combination
ratings are based on R-22.
