! 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.

Remote controller (wireless kit) transmitting distance can be
shorter than expected in rooms with electronic fluorescent
lamps (inverter or rapid start types). Install the indoor unit
far away from fluorescent lamps as much as possible.
Indoor units are for indoor installation only. Outdoor units
can be installed either outdoors or indoors. This unit is for
indoor use.
Do not install the air conditioner or heat pump in the
following locations:
(a) Where a mineral oil mist or oil spray or vapor is
produced, for example, in a kitchen. Plastic parts may
deteriorate and fall off or result in water leakage.
(b) Where corrosive gas, such as sulfurous acid gas, is
produced. Corroding copper pipes or soldered parts
may result in refrigerant leakage.
(c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of
the control system and cause the unit to malfunction.
(d) Where flammable gas may leak, where there is carbon
fiber, or ignitable dust suspension in the air, or where
volatile flammables such as thinner or gasoline are
handled. Operating the unit in such conditions can cause
a fire.
Take adequate measures to prevent the outdoor unit from
being used as a shelter by small animals. Small animals
making contact with electrical parts can cause malfunctions,
smoke, or fire. Instruct the user to keep the area around the
unit clean.
! DANGER
Refrigerant gas is heavier than air and replaces oxygen. A
massive leak can lead to oxygen depletion, especially in
basements, 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 into 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 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,
including plastic packing materials used for transportation
may cause injuries or death by suffocation.
! NOTE
Install the power supply and inter-unit wires for the indoor
and outdoor units at least 3.5ft away from televisions or
radios to prevent image interference or noise. Depending
on the radio waves, a distance of 3.5ft may not be sufficient
to eliminate the noise.
Dismantling the unit, treatment of the refrigerant, oil and
additional parts must be done in accordance with the relevant
local, state, and national regulations.
Do not use the following tools that are used with conventional
refrigerants: gauge manifold, charge hose, gas leak detector,
reverse flow check valve, refrigerant charge base, vacuum
gauge, or refrigerant recovery equipment.
If the conventional refrigerant and refrigerator oil are mixed
in R410A, the refrigerant may deteriorate.
This air conditioner or heat pump is an appliance that should
not be accessible to the general public.
As design pressure is 536 psi, the wall thickness field-
installed pipes should be selected in accordance with the
relevant local, state, and national regulations.

INSTALLATION OF THE OUTDOOR UNIT
1. Precautions for Selecting a Location
Choose a place solid enough to bear the weight and vibration of the unit, where the operating sound will not be
amplified.
Choose a location where the hot air discharged from the unit or the operating sound will not cause a nuisance to the
neighbors of the user.
Avoid locations, such as near bedrooms, where the operating sound may cause disturbance.
There must be sufficient space to carry the unit into and out of the site.
There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.
The site must not be prone to flammable gas leaks in the surrounding area.
Install units, power cords and inter-unit wire at least 10ft (3m) away from television and radio sets. (This is to prevent
interference to images and sounds. Noise may be produced even if they are more than 10ft (3m) away depending on radio
wave conditions.)
In coastal areas or other places with a salty atmosphere or one containing sulfate gas, corrosion may shorten the life of
the air conditioner.
Since water will flow from the drain of the outdoor unit, do not place under the unit anything which must be kept away
from moisture.
NOTE
Cannot be installed suspended from a ceiling or stacked.
! CAUTION
When operating the air conditioner in a low outdoor ambient temperature, be sure to follow the
instructions described below.
To prevent exposure to wind, install the outdoor unit with its suction side facing the wall.
Never install the outdoor unit at a site where the suction side may be exposed directly to
wind.
To prevent exposure to wind, it is recommended to install a baffle plate on the air discharge
side of the outdoor unit.
In heavy snow areas, select an installation site where the snow will not affect the unit.
If there is a likelihood of snow accumulating on the outdoor unit, attach a snow protection

*Be sure to add the proper amount of additional refrigerant. Failure to do so may result in reduced performance.
Remark: The refrigerant pre-charged in the outdoor unit is for piping length up to 25ft (7.6m).
Allowable Piping Length
If the pipe is too long, both the capacity and reliability of the unit will drop. As the number of bends increases, resistance to
the flow of refrigerant system increases, thus lowering cooling capacity. As a result, the compressor may become defective.
Always choose the shortest path and follow the recommendations as tabulated below:

Piping Works And Flaring Technique
Do not use contaminated or damaged copper tubing. If
any piping, evaporator or condenser had been exposed or
had been opened for 15 seconds or more, the system must
be vacuumed. Generally do not remove plastic, rubber
plugs and brass nuts from the valves, fittings, tubing and
coils until it is ready to connect suction or liquid line into
valves or fittings.
If any brazing work is required, ensure that nitrogen gas
is passed through coil and joints while the brazing work
is being done. This will eliminate soot formation on the
inside wall of copper tubings.
Cut the pipe stages by stages, advancing the blade of pipe
cutter slowly. Extra force and a deep cut will cause more
distortion of pipe and therefore extra burr. See Figure I.
Remove burrs from cut edges of the pipes with remover. See
Figure II. Hold the pipe on top position and burr remover
at lower position to prevent metal chips from entering the
pipe. This will avoid unevenness on the flare faces which
will cause gas leak.
Insert the flare nuts, mounted on the connection parts
of both the indoor unit and outdoor unit, into the copper
pipes.
The exact length of pipe protruding from the top surface
of the swaging block is determined by the flaring tool.
See Figure III.
Fix the pipe firmly on the swaging block. Match the centers
of both the swaging block and the flaring punch, then
tighten the flaring punch fully.
The refrigerant pipe connection are insulated by closed
cell polyurethane.
Piping Connection To The Units
Align the center of the piping and tighten the flare nut
sufficiently with fingers. See Figure IV.
Finally, tighten the flare nut with torque wrench until the
wrench clicks.
When tightening the flare nut with the torque wrench,
ensure that the tightening direction follows the arrow
indicated on the wrench.
The refrigerant pipe connection are insulated by closed
cell polyurethane.

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT
R410A is a new HFC refrigerant which does not damage the
ozone layer. The working pressure of this new refrigerant is
1.6 times higher than conventional refrigerant (R22), thus
proper installation/servicing is essential.
Never use refrigerant other than R410A in an air conditioner
which is designed to operate with R410A.
POE or PVE oil is used as lubricant for R410A compressor,
which is different from the mineral oil used for R22
compressor. During installation or servicing, extra precaution
must be taken not to expose the R410A system too long
to moist air. Residual POE or PVE oil in the piping and
components can absorb moisture from the air.
To prevent mischarging, the diameter of the service port
on the flare valve is different from that of R22.
Use tools and materials exclusively for refrigerant R410A.
Tools exclusively for R410A are manifold valve, charging
hose, pressure gauge, gas leak detector, flare tools, torque
wrench, vacuum pump and refrigerant cylinder.
As an R410A air conditioner incurs higher pressure
than R22 units, it is essential to choose the copper pipes
correctly.
If the refrigerant gas leakage occurs during installation/
servicing, be sure to ventilate fully. If the refrigerant gas
comes into contact with fire, a poisonous gas may occur.
When installing or removing an air conditioner, do not
allow air or moisture to remain in the refrigerant cycle.
VACUUMING AND CHARGING
Vacuuming is necessary to eliminate all moisture and air from the system.
Vacuuming The Piping And The Indoor Unit
Except for the outdoor unit which is pre-charged with
refrigerant, the indoor unit and the refrigerant connection
pipes must be air-purged because the air containing moisture
that remains in the refrigerant cycle may cause malfunction
of the compressor.
Remove the caps from the valve and the service port.
Connect the center of the charging gauge to the vacuum
pump.
Connect the charging gauge to the service port of the 3-way
valve.
Start the vacuum pump. Evacuate for approximately 30
minutes. The evacuation time varies with different vacuum
pump capacity. Confirm that the charging gauge needle has
moved towards -14.7psi (-760mmHg).
Caution
If the gauge needle does not move to -14.7psi (-760mmHg),
be sure to check for leakage at flare type connection of
the indoor and outdoor unit and repair the leak before
proceeding to the next step.
Close the valve of the changing gauge and stop the vacuum
pump.
On the outdoor unit, open the suction valve (3 way) and
liquid valve (2 way) (in anti-clockwise direction) with
5/32" (4mm) key for hexagon sacked screw.
Charge Operation
This operation must be done by using a gas cylinder and a
precise weighing machine. The additional charge is topped-up
into the outdoor unit using the suction valve via the service
port.
Remove the service port cap.
Connect the low pressure side of the charging gauge to the
suction service port center of the cylinder tank and close
the high pressure side of the gauge. Purge the air from the
service hose.
Start the air conditioner unit.
Open the gas cylinder and low pressure charging valve.
When the required refrigerant quantity is pumped into
the unit, close the low pressure side and the gas cylinder
valve.
Disconnect the service hose from service port. Put back
the service port cap.

Additional refrigerant charge [oz (g)] per additional 3.28ft (1m) length as tabulated.
The refrigerant is pre-charged in the outdoor unit. If the piping length is less than 25ft (7.6m), then additional charge after
vacuuming is not necessary. If the piping length is more than 25ft (7.6m), then use the additional charge value as indicated
in the table.
Example:
FTXB09 & RXB09 with 39.4ft (12m) piping length, additional piping length is 14.4ft (4.4m).
Thus, Additional charge = 14.4ft (4.4m)x 0.21oz/ft [20g/m]
= 3.024oz [88.0g]
