SAFETY CONSIDERATIONS

Read these “SAFETY CONSIDERATIONS for Installation” carefully 
before installing air conditioning equipment. After completing the instal-
lation, make sure that the unit operates properly during the startup oper-
ation.
Instruct the customer on how to operate and maintain the unit. Inform 
customers that they should store this Installation Manual with the Oper-
ation Manual for future reference.
Always use a licensed installer or contractor to install this product. 
Improper installation can result in water or refrigerant leakage, electrical 
shock, fire, or explosion.

DANGER

Refrigerant gas is heavier than air and replaces oxygen. A mas-
sive leak can lead to oxygen depletion, especially in base-
ments, and an asphyxiation hazard could occur leading to 
serious injury or death.

Do not ground units to water pipes, gas pipes, telephone wires, 
or lightning rods as incomplete grounding can cause a severe 
shock hazard resulting in severe injury or death. Additionally, 
grounding to gas pipes could cause a gas leak and potential 
explosion causing severe injury or death.

If refrigerant gas leaks during installation, ventilate the area 
immediately. Refrigerant gas may produce toxic gas if it comes 
in contact with fire. Exposure to this gas could cause severe 
injury or death.

After completing the installation work, check that the refriger-
ant gas does not leak throughout the system.

Do not install unit in an area where flammable materials are 
present due to risk of explosions that can cause serious injury 
or death.

Safely dispose all packing and transportation materials in 
accordance with federal/state/local laws or ordinances. Packing 
materials such as nails and other metal or wood parts, includ-
ing plastic packing materials used for transportation may cause 
injuries or death by suffocation.

WARNING

Only qualified personnel must carry out the installation work. 
Installation must be done in accordance with this installation 
manual. Improper installation may result in water leakage, elec-
tric shock, or fire.

When installing the unit in a small room, take measures to keep 
the refrigerant concentration from exceeding allowable safety 
limits. Excessive refrigerant leaks, in the event of an accident in 
a closed ambient space, can lead to oxygen deficiency.

Use only specified accessories and parts for installation work. 
Failure to use specified parts may result in water leakage, elec-
tric shocks, fire, or the unit falling.

Install the air conditioner on a foundation strong enough that it 
can withstand the weight of the unit. A foundation of insuffi-
cient strength may result in the unit falling and causing injuries.

Take into account strong winds, typhoons, or earthquakes 
when installing. Improper installation may result in the unit fall-
ing and causing accidents.

Make sure that a separate power supply circuit is provided for 
this unit and that all electrical work is carried out by qualified 
personnel according to local, state, and national regulations. 
An insufficient power supply capacity or improper electrical 
construction may lead to electric shocks or fire.

Make sure that all wiring is secured, that specified wires are 
used, and that no external forces act on the terminal connec-
tions or wires. Improper connections or installation may result 
in fire.

When wiring, position the wires so that the control box cover 
can be securely fastened. Improper positioning of the control 
box cover may result in electric shocks, fire, or the terminals 
overheating.

Before touching electrical parts, turn off the unit.

Be sure to install a ground fault circuit interrupter if one is not 
already available. This helps prevent electrical shocks or fire.

Securely fasten the outdoor unit terminal cover (panel). If the 
terminal cover/panel is not installed properly, dust or water may 
enter the outdoor unit causing fire or electric shock.

When installing or relocating the system, keep the refrigerant 
circuit free from substances other than the specified refrigerant 
(R410A) such as air. Any presence of air or other foreign sub-
stance in the refrigerant circuit can cause an abnormal pres-
sure rise or rupture, resulting in injury.

Do not change the setting of the protection devices. If the pres-
sure switch, thermal switch, or other protection device is 
shorted and operated forcibly, or parts other than those speci-
fied by Daikin are used, fire or explosion may occur.

CAUTION

Do not touch the switch with wet fingers. Touching a switch 
with wet fingers can cause electric shock.

Do not allow children to play on or around the unit to prevent 
injury.

Do not touch the refrigerant pipes during and immediately after 
operation as the refrigerant pipes may be hot or cold, depend-
ing on the condition of the refrigerant flowing through the 
refrigerant piping, compressor, and other refrigerant cycle 
parts. Your hands may suffer burns or frostbite if you touch the 
refrigerant pipes. To avoid injury, give the pipes time to return 
to normal temperature or, if you must touch them, be sure to 
wear proper gloves.
