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.)
