NOTES:

1. Ratings are gross, and do not account for the effects of the indoor-
fan motor power and heat.
34.0
2. Direct interpolation is permissible. Do not extrapolate.
17.8
3. SHC is based on 26.7 C db temperature of air entering the unit. At
6.94
any other temperature, correct the SHC read from the table of cool-
33.6
ing capacities as follows:
17.9
Corrected SHC
7.52
= SHC + [1.23 x 10
32.8
17.7
Observe the rule of signs. Above 26.7 C, SHC correction will be pos-
8.10
itive; add it to SHC. Below 26.7 C, SHC correction will be negative;
subtract it from SHC.
