1PRECAUTIONS FOR SAFETY
•Ensure that all Local, National and International regulations are satisfied.
•Read this “PRECAUTIONS FOR SAFETY”carefully before Installation.
•The precautions described below include the important items regarding safety. Observe them without fail.
•After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
•Turn off the main power supply switch (or breaker) before the unit maintenance.
•Ask the customer to keep the Installation Manual together with the Owner’s Manual.
CAUTION New Refrigerant Air Conditioner Installation
•THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT
DESTROY OZONE LAYER.
The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure
is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil
has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging
port of the main unit and installation tools are charged from those for the conventional refrigerant.
Accordingly the exclusive tools are required for the new refrigerant (R410A).
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust
does not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance
force and impurity in it.
CAUTION To Disconnect the Appliance from Main Power Supply.
This appliance must be connected to the main power supply by means of a switch with a contact separation of
at least 3 mm.
The installation fuse must be used for the power supply line of this conditioner.
WARNINGS
•Ask an authorized dealer or qualified installation professional to install/maintain the air
conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
•Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
•Connect the connecting wire correctly.
If the connecting wire is connected in a wrong way, electric parts may be damaged.
•When moving the air conditioner for the installation into another place, be very careful not to
enter any gaseous matter other than the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes
abnormally high and it may resultingly causes pipe burst and injuries on persons.
•Do not modify this unit by removing any of the safety guards or by by-passing any of the
safety interlock switches.
•Exposure of unit to water or other moisture before installation may cause a short-circuit of
electrical parts.
Do not store it in a wet basement or expose to rain or water.

3
•After unpacking the unit, examine it carefully if there are possible damage.
•Do not install in a place that might increase the vibration of the unit.
•To avoid personal injury (with sharp edges), be careful when handling parts.
•Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
•When the air conditioner is installed in a small room, provide appropriate measures to
ensure that the concentration of refrigerant leakage occur in the room does not exceed the
critical level.
•Install the air conditioner securely in a location where the base can sustain the weight
adequately.
•Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
•If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
•After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas
might generate.
•Electrical work must be performed by a qualified electrician in accordance with the
Installation Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
•Use the specified wires for wiring connect the terminals securely fix. To prevent external
forces applied to the terminals from affecting the terminals.
•Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
•Do not install the air conditioner in a location subject to a risk of exposure to a combustible
gas.
If a combustible gas leaks, and stays around the unit, a fire may occur.

2SELECTION OF INSTALLATION PLACE
WARNING
•Install the air conditioner at enough strong place to withstand the weight of the unit.
If the strength is not enough, the unit may fall down resulting in injury.
•Install the air conditioner at a height 2.5m or more from the floor.
If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous
because you may contact with revolving fan or active electricity.
CAUTION
•Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.
If a combustible gas leaks and stays around the unit, a fire may occur.
Upon approval of the customer, install the air conditioner in a place that satisfies the following conditions.
•Place where the unit can be installed horizontally.
•In the process after removing the ceiling panel, it important to reinforce the groundwork (framework) and
keep a level correctly of the existing ceiling to prevent vibration of the ceiling panel.
•Place where a sufficient servicing space can be ensured for safety maintenance and check.
•Place where drained water will not cause any problem.
Avoid installing in the following places.
•Place exposed to air with high salt content (seaside area), or place exposed to large quantities of sulfide gas
(hot spring). (Should the unit be used in these places, special protective measures are needed.)
•Place exposed to oil, vapor, oil smoke or corrosive gas.
•Place where organic solvent is used nearby.
•Place close to a machine generating high frequency.
•Place where the discharged air blows directly into the window of the neighboring house. (For outdoor unit)
•Place where noise of the outdoor unit is easily transmitted.
(When installing the air conditioner on the boundary with the neighbor, pay due attention to the level of noise.)
•Place with poor ventilation.
(Before air ducting work, check whether value of air volume, static pressure and duct resistance are correct.)
Installation space
Secure the space required to installation
and servicing.
Selection of installation place
In case of continued operation of the indoor unit under high-
humidity conditions as described below, dew may condense
and water may drop.

<Round duct>
In case of the round duct, use the thermal insulator of
thickness 25mm or more and inner diameter 150mm
or more to the duct board.
(If the inner diameter is not enough, resistance
increase, as the result, air does not flow smoothly and
loss of the static pressure increases.) For the thermal
insulator, use high-density glass wool of 24kg/m3 or
equivalent.
<Square duct> (Reference for square duct)
When using the square duct, change the type of the
air supply flange from round type to square flange at
the local site.
Connecting method of the duct
1. Supply air side
<Round duct> <Square duct>

<Round duct>
1. Make the round duct according to inner dimension

Use a glass wool board with inside/outside finishing
25mm-thickness and 24kg/m³-density.
2. Connect the flange and each type of duct. (Fig. 1)
Fig. 1
Fig. 2
Points at installation work
nGeneral cautions
1. Considering installation places of indoor unit supply chamber, structure of the building and determine the
duct path.
2. In order to utilize the static pressure characteristics of the air supply in the indoor unit, design the duct
branching having the large size of the air supply chamber or setting distance to the first branch as long as
possible (Min. : 200mm or longer) so that an even air volume can be obtained.
Especially, when branching just after air supply of the indoor unit, air concentrates at the center part and is
difficult to flow to the ducts at both sides.
3. Connect each connecting section surely, and apply sufficient thermal insulation.
In this model of which the duct is branched in the ceiling, compared with the model for ordinary houses, the
high temperature generates on the periphery in the cooling time (Especially, at attic and etc.), temperature
difference increases between the supply air and outside of the duct, and dewing may occur.
Dewing on the surface of the thermal insulator covering the metal connecting section or leaking portion of
the cooled air may cause a trouble such as water drops.
4. Thermal insulation of screwing sections is necessary.
Prevent dewing by applying thermal insulation to 6 screws those fix the duct flange of the air supply chamber.
•For duct parts, the flexible branch duct (thermal insulation, 25mm or more thickness) is recommended.
•Adjust the duct length to 6m or less even for straight pipe, and avoid sharp bending
(Air flow resistance is large.) if bending.
<Square duct>
1. Using 6 screws, mount the flange to the supply air
port of the indoor unit. (Fig. 2)
2. Make the square duct according to inner dimension
of the flange A x B .
Use a glass wool board with inside/outside
finishing 25mm-thickness and 24kg/m³-density.
3. Connect the flange and each type of duct. (Fig. 3)

Piping material
•For laying pipes underground, use hard vinyl
chloride pipe. VP25 (Inner diamater Ø32mm)
Piping and cautions
•Set drain side of pipe at downward slope.
(1/100 or more)
•Be sure to apply thermal insulation (foaming
polyethylene, 10mm-thickness or more) for pipes
passing through the room.
•Adhere the connecting sections with vinyl chloride
agent surely so that no water leakage is caused.
•Apply adhesive agent without unevenness around
the portion approx. 40mm from the end of hard
polyvinyl-chloride pipe.
•Push the vinyl pipe in the drain socket completely
up to the end of the socket.
•Do not apply strength to the connecting part until
the adhesive agent has dried and hardened.
•Support the piping with hanging bracket so that the
force is not applied to connection sections of pipe
and pipe is not waved.
NOTES :
•Do not make slack or trap at halfway across piping.
•Set pipes so that the end of drain pipe is not dipped in
water, and also keep space 50mm or more to the
ground.
•After piping work, check if water drains smoothly.
•Hole should be made at a slight downward slant to
the outdoor side.
•When connecting extension drain hose, insulate the
connecting part of extension drain hose with shield
pipe.
Thermal-insulating process

6REFRIGERANT PIPING AND EVACUATING
Refrigerant piping
1. If the outdoor units are to be mounted on a wall,
make sure that the supporting platform is
sufficiently strong. The platform should be
designed and manufactured to maintain its
strength over a long period of time, and sufficient
consideration should be given to ensuring that the
outdoor unit will not fall.
2. Use copper pipe with 0.8 mm or more
thickness.
(In case pipe size is Ø15.9, with 1.0mm or more.)
3. Flare nut and flare works are also different from
those of the conventional refrigerant.
Take out the flare nut attached to the main unit of
the air conditioner, and use it.
CAUTION
IMPORTANT 4 POINTS FOR PIPING WORK
1. Remove dust and moisture from the inside of the
connecting pipes.
2. Tight connection (between pipes and unit)
3. Evacuate the air in the connecting pipes using
VACUUM PUMP.
4. Check the gas leakage. (connected points)
Permissible piping length and heat
They vary according to the outdoor unit. For details,
refer to the Installation Manual attached to the outdoor
unit.
Flaring
Insert a flare nut into the pipe, and flare the pipe.
As the flaring sizes of R410A differ from those of
refrigerant R22, the flare tools newly manufactured for
R410A are recommended.
However, the conventional tools can be used by
adjusting projection margin of the copper pipe.

•Flaring dia meter size :
A (Unit : mm)
* In the case of flaring for R410A with the conventional
flare tool, pull out it approx. 0.5 mm more than that for
R22 to adjust to the specified flare size.
The copper pipe gauge is useful for adjusting
projection margin size.
Tightening connection
CAUTION
•Do not apply excessive torque. Otherwise, the nut
may crack depending on the conditions.
(Unit : N•m)
•Tightening torque of flare pipe connections
Pressure of R410A becomes higher than that of R22.
(Approx. 1.6 times) Therefore, using a torque wrench,
tighten firmly the flare pipe connecting sections which
connect the
indoor and outdoor units up to
the specified tightening torque.
Incorrect connections may
cause not only a gas leakage,
but also a trouble of the
refrigeration cycle or
compressor damage.
Align the centers of the connecting pipes and tighten the
flare nut as far as possible with your fingers.
Then tighten the nut with a spanner and torque wrench
as shown in the figure.

Piping with outdoor unit
•Shape of valve differs according to the outdoor unit.
For details of installation, refer to the Installation
Manual of the outdoor unit.
Air purge
Using a vacuum pump, perform vacuuming from the
charge port of valve of the outdoor unit.
For details, follow to the Installation Manual attached
to the outdoor unit.
•Never use the refrigerant sealed in the outdoor unit
for air purge.
REQUIREMENT
For the tools such as charge hose, etc., use those
manufactured exclusively for R410A.
Refrigerant amount to be added
For addition of the refrigerant, add refrigerant “R410A”
referring to the attached Installation Manual of outdoor
unit.
Be sure to use a scale to charge the refrigerant of
specified amount.
REQUIREMENT
•Charging an excessive or too little amount of
refrigerant causes a trouble of the compressor.
Be sure to charge the refrigerant of specified
amount.
•A personnel who charged the refrigerant should
write down the pipe length and the added
refrigerant amount in the nameplate attached to
the service panel of the outdoor unit. It is
necessary to troubleshoot the compressor and
refrigeration cycle malfunction.
Open the valve fully
Open the valve of the outdoor unit fully.
For details, refer to the Installation Manual attached to
the outdoor unit.
Gas leak check
Check with a leak detector or soap water whether gas
leaks or not, from the pipe connecting section or cap
of the valve.
REQUIREMENT
Use a leak detector manufactured exclusively for
HFC refrigerant (R410A, R134a, etc.).
Thermal insulation process
Apply thermal insulation for the pipes separately at
liquid side and gas side.
For the thermal insulation to the pipes at gas side, be
sure to use the material with heat-resisting
temperature 120°C or higher.
Using the attached thermal insulation material, apply
the thermal insulation to the pipe connecting section of
the indoor unit securely without gap.
REQUIREMENT
Apply the thermal insulation to the pipe
connecting section of the indoor unit securely up
to the root without exposure of the pipe. (The pipe
exposed to the outside causes water leak.)
