CAUTION

Important Note to the Owner Regarding Prod-
uct Warranty

Your warranty certificate is supplied as a separate document
with the unit installed by your contractor. Read the limited
warranty certificate carefully to determine what is and is not
covered and keep the warranty certificate in a safe place. If you
are unable to locate the warranty certificate please contact
your installing contractor or contact customer service (877-
254-4729) to obtain a copy.

Shipping Inspection

Always keep the unit upright; laying the unit on its side or top
may cause equipment damage. Shipping damage, and subse-
quent investigation is the responsibility of the carrier.  Verify
the model number, specifications, electrical characteristics,
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
performance is achieved after 72 hours of operation.

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.

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