WARNING

CAUTION

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 installation
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 to withstand the weight of the unit. A
foundation of insufficient 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
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 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 electrical wiring
box cover can be securely fastened. Improper positioning of
the electrical wiring box cover may result in electric shock,
fire, or the terminals overheating.
Before touching electrical parts, turn off the unit.
It is recommended to install a ground fault circuit interrupter
if one is not already available. This helps prevent electric
shock 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 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 protection device
is shorted and operated forcibly, or parts other than those
specified by Daikin are used, fire or explosion may occur.

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.
The heat exchanger fins are sharp enough to cut. To avoid
injury wear gloves or cover the fins while working around
them.
Do not touch the refrigerant pipes during and immediately
after operation as the refrigerant pipes may be hot or cold,
depending 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.
Install drain piping to proper drainage. Improper drain piping
may result in water leakage and property damage.
Insulate piping to prevent condensation.
Be careful when transporting the product.
Do not turn off the power immediately after stopping
operation. Always wait for at least 5 minutes before turning
off the power. Otherwise, water leakage may occur.
Do not use a charging cylinder. Using a charging cylinder
may cause the refrigerant to deteriorate.
Refrigerant R410A in the system must be kept clean, dry,
and tight.

(a) Clean and Dry -- Foreign materials (including mineral

oils such as SUNISO oil or moisture) should be
prevented from getting into the system

(b) Tight -- R410A does not contain any chlorine, does not

destroy the ozone layer, and does not reduce the earth’s
protection again harmful ultraviolet radiation. R410A
can contribute to the greenhouse effect if it is released.
Therefore, take proper measures to check for the
tightness of the refrigerant piping installation. Read the
chapter Refrigerant Piping and follow the procedures.

Since R410A is a blend, the required additional refrigerant
must be charged in its liquid state. If the refrigerant is charged
in a state of gas, its composition can change and the system
will not work properly.
The indoor unit is for R410A. See the catalog for indoor
models that can be connected. Normal operation is not
possible when connected to other units.
