and accessories are correct prior to installation. The distribu-
tor or manufacturer will not accept claims from dealers for trans-
portation damage or installation of incorrectly shipped units.
Codes & Regulations
This product is designed and manufactured to comply with
national codes. Installation in accordance with such codes and/
or prevailing local codes/regulations is the responsibility of the
installer. The manufacturer assumes no responsibility for equip-
ment installed in violation of any codes or regulations. Rated

brand products. Within either website, please select the resi-
dential or commercial products menu and then select the
submenu for the type of product 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 not allowed.
Outdoor units are approved for operation above 55°F in cooling
mode. Operation below 55°F in cooling mode requires the use
of an approved low ambient kit.
Damage to the unit caused by operating the unit in a structure
that is not complete (either as part of new construction or reno-
vation) is not covered under the warranty.
