Outwardly, many models appear Models and SEER Ranges Table 1 — Condensing Units similar, however, there are distinct differences. Tables l and 2 help to differentiate these differences.

The higher the number, the less electrical power required to reach a given capacity. SEER is derived by dividing output energy by input energy. fC.O.P. — Coefficient of Performance (heating), determined by dividing Btu output by power input required to producethis Btu output. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. PC101 Catalog No. 563-857 Printed in U.S.A.
