ment installed in violation of any codes or regulations.  Rated
performance is achieved after 72 hours of operation. Rated
performance is delivered at the specified airflow. See outdoor
unit specification sheet for split system models or product
specification sheet for packaged and light commercial mod-
els. Specification sheets can be found at

ther website, please select the residential or commercial prod-
ucts menu and then select the submenu for the type of prod-
uct to be installed, such as air conditioners or heat pumps, to
access a list of product pages that each contain links to that
model’s specification sheet.

The United States Environmental Protection Agency (EPA)
has issued various regulations regarding the introduc-
tion and disposal of refrigerants. Failure to follow these
regulations may harm the environment and can lead to
the imposition of substantial fines. 

Should you have any

questions please contact the local office of the EPA.

If replacing a condensing unit or air handler, the system must
be manufacturer approved and Air Conditioning, Heating and
Refrigeration Institute (AHRI) matched.  

NOTE: 

Installation of

unmatched systems is strongly discouraged.

Outdoor units are approved for operation above 55°F in cooling
mode.  Operation below 55°F requires the use of an approved
low ambient kit.

Operating the unit in a structure that is not complete (either as
part of new construction or renovation) will void the warranty.

EATURES

This air conditioner is a part of the ComfortNet™ family of prod-
ucts.  It may be installed as part of a “legacy” system using a
standard 24 VAC thermostat.  However, with the CTK0*
ComfortNet thermostat kit, this air conditioner may be installed
as part of a digitally communicating system.  The ComfortNet
system provides automatic airflow configuration, enhanced setup
features, and enhanced diagnostics.  It also reduces the num-
ber of thermostat wires to a maximum of four and a minimum
of two.
