NOTES:
1. To obtain total outdoor unit power, add outdoor fan kW shown to
compressor draw: PH1S090 — .96 kW.
2. Ratings are without supplementary heat and are based on 70 F db
air entering indoor unit. Wet-bulb temperature entering outdoor unit
varies with dry bulb; at 47 F db, wb is 43 F; at 17 F db, wb is 15 F.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. SHC is based on 80 F db air entering indoor coil.
Below 80 F db, subtract (Corr Factor x Cfm) from SHC.
Above 80 F db, add (Corr Factor x Cfm) to SHC.

length is equal to the actual length plus a 50% allowance for fitting
losses.)
