INSTALLATION INSTRUCTIONS
Codes & Regulations
This product is designed and manufactured to comply with na-
tional codes. Installation in accordance with such codes and/or
prevailing local codes/regulations is the responsibility of the in-
staller. The manufacturer assumes no responsibility for equip-
ment installed in violation of any codes or regulations. Rated
performance is achieved after 20 hours of operation. Rated per-
formance is delivered at the specified airflow. See outdoor unit
specification sheet for split system models or product specifica-
tion sheet for packaged and light commercial models. Specifica-
tion sheets can be found at
products. Within the website, please select the residential or com-
mercial 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 introduction and dis-
posal of refrigerants. Failure to follow these regulations may
harm the environment and can lead to the imposition of sub-
stantial 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 Re-
frigeration Institute (AHRI) matched. NOTE: Installation of un-
matched systems is strongly discouraged.
Refer to the unit Specification Sheet for the recommended in-
door model selection. NOTE: This unit must be used with a pur-
chased two stage room thermostat with 24 VAC control circuitry.
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.
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.
Installation Clearances
This unit is designed for outdoor installations only. Special con-
sideration must be given to location of the condensing unit(s) in
regard to structures, obstructions, other units, and any/all other
factors that may interfere with air circulation. Where possible,
the top of the unit should be completely unobstructed; how-
ever, if vertical conditions require placement beneath an obstruc-
tion there should be a minimum of 60 inches between the top
of the unit and the obstruction(s). The specified dimensions meet
requirements for air circulation only. Consult all appropriate regu-
latory codes prior to determining final clearances.
