Safety considerations
Read these Safety considerations for Installation carefully before
installing an air conditioner or heat pump. 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,
electrical shock, fire, or explosion.

This symbol identifies useful tips or
additional information.
DANGER
▪ Refrigerant gas is heavier than air and replaces
oxygen. A massive leak will result in oxygen depletion,
especially in basements, and an asphyxiation hazard
will result in serious injury or death.
▪ Do not ground units to water pipes, gas pipes,
telephone wires, or lightning rods as incomplete
grounding will result a severe shock hazard resulting in
severe injury or death. Additionally, grounding to gas
pipes will result a gas leak and potential explosion
resulting in severe injury or death.
▪ If refrigerant gas leaks during installation, ventilate the
area immediately. Refrigerant gas will result in
producing toxic gas if it comes into contact with fire.
Exposure to this gas will result in 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 materials
are present due to risk of explosions that will result in
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, including plastic packing materials
used for transportation will result in 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 could 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,
could result in oxygen deficiency.
▪
Use only specified accessories and parts for installation
work. Failure to use specified parts could result in water
leakage, electric shocks, 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 could result in
the unit falling and causing injuries.
▪
Take into account strong winds, typhoons, or
earthquakes when installing. Improper installation could
result in the unit falling 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
could result in 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 connections or wires. Improper connections or
installation could 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 could result in electric shocks,
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 grounding
system in North America, a dedicated GFCI is not
necessary.
▪
Securely fasten the unit terminal cover (panel). If the
terminal cover/panel is not installed properly, dust or
water may enter the outside unit and could result in 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 substance in the refrigerant circuit
could result in 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 protection
device is shorted and operated forcibly, or parts other
than those specified by Daikin are used, fire or
explosion could result.
CAUTION
▪
Do not touch the switch with wet fingers. Touching a
switch with wet fingers may result in electric shock.
▪
Do not allow children to play on or around the unit or it
may result in injury.
▪
The heat exchanger fins are sharp enough to cut, and
may result in injury if improperly used. To avoid injury
wear glove or cover the fins when working around
them.
