NOTES:
1. Gross cooling capacity is based on 67 F wb, 80 F db air entering in-
door unit and 95 F db air entering outdoor unit.
2. Net heating capacity is based on 70 F db air entering indoor unit and
47 F db, 43 F wb air entering outdoor unit. Includes indoor fan heat
and defrost effects.

Cap. — Integrated Heating Capacity (1000 Btuh) — includes indoor-
fan motor heat and effects of defrost.
kW — Total Compressor Motor Power Input
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.
