‘Outdoor coil requires replacement of AccuRaterT“ refrigerant control
piston when used with specified 38HQ unit Replacement piston is
factory supplied See Installation, Start-Up and Service Instructions
for piston sizes
Rated in accordance with ARI Standards
240-76 and 270-75
Ratings are net values, reflecting the effects of circulating fan heat
Supplementary electric heat is not included Ratings are based on
Cooling Standard: 80 F db, 67 F wb indoor entering air temperature
and 95 F db air entering outdoor unit
Hi-Temp Heating Standard: 70 F db indoor entering air temperature
and
47 F db, 43 F wb air entering outdoor unit
Lo-Temp Heating Standard: 70 F db indoor entering air temperature
and 17 F db, 15 F wb air entering outdoor unit
COMBINATION RATING NOTES
1 Direct interpolation is permissible Do not extrapolate
2 SHC is based on 80 F db temperature of air entering indoor unit
Below 80 F db, subtract (corr factor x cfm) from SHC
Above 80 F db. add {corr factor x cfm) to SHC
