Lennox KCC Series Unit Information

S e r v i c e L i t e r a t u r e
The KCC 7.5, 8.5, 10 and 12.5 ton (092, 102, 120, 150)
packaged cooling units are available in standard cooling
efficiency. Optional auxiliary electric heat is factory- or
field-installed in KCC units. Electric heat operates in sin-
gle or multiple stages depending on the kW input size.
7.5kW through 60kW heat sections are available for the
KCC packaged cooling units.
Standard and high efficiency units come standard with a
lightweight, all-aluminum condenser coil; optional, fin/tube
condenser coils are available. Hot gas by-pass (reheat) is
now an option for standard efficiency KCC units with fin
tube coils.
All KCC units are designed to accept any of several differ-
ent energy management thermostat control systems with
minimum field wiring. Factory- or field-provided control op-
tions connect to the unit with jack plugs. When "plugged
in" the controls become an integral part of the unit wiring.
