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

DANGER
• Refrigerant gas is heavier than air and replaces oxy-
gen.
A massive leak can lead to oxygen depletion, espe-
cially in basements, and an asphyxiation hazard could
occur leading to serious injury or death.
• Do not ground units to water pipes, gas pipes, tele-
phone wires, or lightning rods as incomplete ground-
ing 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
refrigerant gas does not leak throughout the system.
•
Do not install unit in an area where flammable materi
-
als are present due to risk of explosions that can cause
serious injury or death.
• Safely dispose of all packing and transportation ma-
terials in accordance with federal/state/local laws or
ordinances. Packing materials such as nails and other
metal or wood parts, including plastic packing materi-
als used for transportation may cause injury 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, electric 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 installa
-
tion work. Failure to use specified parts may result in
water leakage, electric shock, fire, or the unit falling.
• Install the air conditioner or heat pump on a foundation
strong enough that it can withstand the weight of the
unit. A foundation of insufficient strength may result in
the unit falling and causing injury.
• Take into account strong winds, typhoons, or earth-
quakes when installing. Improper installation may
result in the unit falling and causing accidents.
• Make sure that a separate power supply circuit is pro-
vided 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 shock or fire.
•
Make sure that all wiring is secured, that specified
wires are used, and that no external forces act on the
terminal connections 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 shock,
fire, or the terminals overheating.
• Before touching electrical parts, turn off the unit.
• This equipment can be installed with a Ground-Fault
Circuit Interrupter (GFCI). Although this is a recognized
measure for additional protection, with the ground-
ing system in North America, a dedicated GFCI is not
necessary.
• When installing or relocating the system, keep the
refrigerant circuit free from substances other than the
specified refrigerant (R410A) such as air. Any pres
-
ence of air or other foreign substance in the refrigerant
circuit can cause an abnormal pressure rise or rupture,
resulting in injury.
• Do not change the setting of the protection devices. If
the pressure switch, thermal switch, or other protec-
tion device is shorted and operated forcibly, or parts
other than those specified by Daikin are used, fire or
explosion may occur.
• Do not install in a wet room such as a bathroom or
laundry room due to a risk of fire or electric shock.
