†
Total capacities are net (I.D. blower heat subtracted) system capacities based on 25’ line set.
If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
†† At TVA rating indoor condition (75
°F
db, 63
°F
wb), all other indoor air temperatures are at 80
°
F db
If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
^
System amps are total of indoor and outdoor amps.
‡
Chart data is for 80
°
F indoor dry bulb. For indoor db temperatures other than 80
°
F, measure Indoor db and Indoor CFM, and plug these into the
formula below. Measure outdoor db and indoor wet bulb, apply these to the chart above, find MBh and S/T, and plug these into the formula below.
(Note: if indoor db is the only thing changing, total capacity, MBh, stays the same.)
Sensible Capacity at Indoor db LOWER than 80
°
F = ( MBh x S/T ) −
( 80 − Indoor db ) x 835 x Indoor CFM

Sensible Capacity at Indoor db HIGHER than 80
°
F = ( MBh x S/T ) +
( Indoor db − 80 ) x 835 x Indoor CFM
