INSTALLATION & SERVICE REFERENCE
Important Safety Instructions
The following symbols and labels are used throughout this manual
to indicate immediate or potential safety hazards. It is the owner's
and installer's responsibility to read and comply with all safety
information and instructions accompanying these symbols. Fail-
ure to heed safety information increases the risk of personal in-
jury, property damage, and/or product damage.
HIGH VOLTAGE!
Disconnect ALL power before servicing. Multiple
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.
Scroll equipped units should never be used to evacuate the air
conditioning system. Vacuums this low can cause internal
electrical arcing resulting in a damaged or failed compressor.

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.

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

Installation Clearances

Special consideration 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 ob-
struction 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 appropri-
ate regulatory codes prior to determining final clearances.

    Refrigerant Lines CAUTION The compressor POE oil for R-410A units is extremely susceptible to moisture absorption and could cause compressor failure. Do not leave system open to atmosphere any longer than necessary for installation. Use only refrigerant grade (dehydrated and sealed) copper tubing to connect the condensing unit with the indoor evaporator.

    Refrigerant Line Connections IMPORTANT To avoid overheating the service valve, TXV valve, or filter drier while brazing, wrap the component with a wet rag, or use a thermal heat trap compound. Be sure to follow the Pressure test the system using dry nitrogen and soapy water to manufacturer’s instruction when using the heat trap locate leaks.

    Local codes often require a disconnect switch located near the unit; do not install the switch on the unit. Refer to the installation instructions supplied with the indoor furnace/air handler for spe- cific wiring connections and indoor unit configuration. Likewise, consult the instructions packaged with the thermostat for mount- ing and location information.
