power sources may be present. Failure to do so may
cause property damage, personal injury or death.
ONLY individuals meeting the requirements (at a minimum)
of an "Entry Level Technician" as specified by the Air
Conditioning, Heating, and Refrigeration Institute (AHRI) may
use this information. Attempting to install or repair this unit
without such background may result in product damage,
personal injury, or death.
Shipping Inspection
Always keep the unit upright; laying the unit on its side or top may
cause equipment damage. Shipping damage, and subsequent in-
vestigation is the responsibility of the carrier. Verify the model
number, specifications, electrical characteristics, and accesso-
ries are correct prior to installation. The distributor or manufac-
turer will not accept claims from dealers for transportation dam-
age or installation of incorrectly shipped units.

INSTALLATION INSTRUCTIONS
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 www.daikincomfort.com for Daikin
brand products. Within the website, please select the residential
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 is-
sued various regulations regarding the introduction 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 Re-
frigeration Institute (AHRI) matched. NOTE: Installation of un-
matched systems is strongly discouraged.
Refer to the unit Specification Sheet for the recommended indoor
model selection. NOTE: This unit must be used with a purchased
single 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.
Do not operate the unit in a structure that is not complete (either
as part of new construction or renovation). Such operation will
void 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; however, if
vertical conditions require placement beneath an obstruction
there should be a minimum of 60 inches between the top of the
unit and the obstruction(s). The specified dimensions meet re-
quirements for air circulation only. Consult all appropriate regu-
latory codes prior to determining final clearances.
