• Ensure that all Local, National and International regulations are satisfied.
• Read this “SAFETY PRECAUTIONS” 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.
1 SAFETY PRECAUTIONS
CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE
LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working pressure of
R410A refrigerant is approx. 1.6 times as that of refrigerant R22. Accompanied with the adoption of the new refrigerant, the
refrigeration machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant,
or refrigeration machine oil does not enter the new type refrigerant R410A air conditioner circuit.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port on main unit and
installation tools are different from those of the conventional refrigerant units. Accordingly, special tools are required for the new
refrigerant (R410A) units as shown on page 23. For connecting pipes, use new and clean piping materials with high pressure
fittings made for R410A only, so that water and/or dust does not enter. Moreover, do not use the existing piping because there are
some problems with pressure fittings and possible impurities in existing piping.
CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY
Disconnection from the supply mains:
The means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.
WARNING
• 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 an electric shock.
• Connect all of the installation wiring correctly.
If the installation wiring is incorrect, electrical parts may be damaged.
• When moving the air-conditioner for installation to another place, be very careful not to allow the specified refrigerant
(R410A) to become mixed with any other gaseous body into the refrigeration circuit. If air or any other gas mixes with the
refrigerant, the gas pressure in the refrigeration circuit will become abnormally high and it may result in the pipe bursting or
personnel injuries.
• Do not modify this unit by removing any of the safety guards or by overriding any of the safety interlock switches.
• Exposure of the unit to water or other forms of moisture before installation may cause a short circuit of the electrical parts.
Do not store it in a wet basement or expose to rain or water.
• The electrical work should be performed by a qualified electrician in accordance with the technical standards for electrical
equipment, internal wiring regulations, and installation manual for the electrical equipment. A dedicated circuit should be
used, and the voltage should match the rated voltage of the product. If the power supply circuit does not have enough
capacity or the work is performed improperly, an electric shock or fire can result.
• Be sure to connect the indoor and outdoor unit wires at their tips. Do not connect the wires below the tips. If the connections
and fixtures are not made properly, overheating or a fire can result.
• Connect the wiring between the indoor and outdoor units so that the cord clamp does not stick out, and attach the covers
properly. If the clamp is not attached properly, the terminal sections can overheat, and a fire or electric shock can result.
• Always use the supplied parts or specified parts for the installation work parts. Usage of different parts can cause the unit to
fall, a water leak, fire, or electric shock.
• After unpacking the unit, examine for 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.
Incorrect installation may result in water leakage, electric shock or a fire.

• When the air conditioner is installed in a small room, provide appropriate measures to ensure that in the event of a refrigerant
leak the rooms does not exceed the critical level.
• Install the air conditioner securely in a location where the base can sustain the weight of the unit 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 unit falling.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gases may be generated.
• 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 gases maybe generated.
• Use only the specified wiring during the unit installation. Ensure that all terminals are securely fixed, so preventing any
external forces having a negative effect on the terminals.
• Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
• Do not install the air conditioner in a location that maybe subjected to a risk of exposure to a combustible gas.
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.
• Do not install in locations where the unit will get splashed by water or with high humidity such as bathrooms. This can cause
deterioration of the insulation, resulting in an electric shock or fire.
• Check the following points before starting operation in the installation work.
- The pipes are securely connected and do not leak.
- The service valve is opened.
Operating the compressor while the service valve is closed will result in an abnormally high pressure, and can possibly
damage the compressor and other parts. Also, any leaks in the connections can cause air to be sucked in, resulting in an
even higher abnormally pressure, and can cause a pipe rupture or injury.
• When carrying out the pump-down work, shut down the compressor before disconnecting the refrigerant pipe. Disconnecting
the refrigerant pipe with the service valve left open and with the compressor still operating will cause air, etc. to be sucked in,
raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in rupturing, injury, etc.
CAUTION
• Wear work gloves when carrying out the installation work or repairs. Contact with parts, etc. may cause injury if the work or
repairs are conducted without wearing gloves.
• Earth leakage breakers are required in certain installation locations. Failure to install the earth leakage breakers can result in
an electric shock.
• The pipes for the drain work should be installed properly in accordance with the installation manual to ensure proper
draining. Failure to install the pipes properly can cause a leak indoors and wet the furniture and other objects in the home.
• Tighten the flare nut with a torque wrench using the specified method. If the flare nut is over-tightened, it can crack over a
long period of time, resulting in a refrigerant leak.
• Do not touch the inlets or aluminum fins of the indoor and outdoor unit. An injury could result.
• Do not install the outdoor unit where small animals typically live. If small animals get inside the unit and touch the electrical
parts, a failure or fire can result. Also, please keep the area around the outdoor unit clear of fallen leaves and other objects.
• After the installation work is completed, perform test operation to check that there is nothing abnormal, and explain to the
customer the operating and cleaning procedures based on the owner's manual. Also, ask the customer to store this
installation manual together with the owner's manual.

4 INSTALLATION OF INDOOR UNIT
WARNING
The installation of the air conditioning unit must be positioned in a location that can sufficiently support its weight and give
protection against adverse environmental conditions. Failure to do so may result in unit damage and possible human injury. Any
incomplete installation may also cause possible risk of human injury.
• Unpack the package, take out the product and then place it on the floor so that the same surface directs underneath as it is
placed in the package.
• Never put the products in a pile or put weight on them, which are taken out from
the packing box; otherwise there is a possibility to damage electric parts, fan
parts, draining mechanism, and etc.
If the both sides are turned over, a deformation of mounting metal of the ceiling
panel which is sold separately, etc. may be caused. Accordingly the product may
be damaged and the installation becomes impossible in some cases.
REQUIREMENT
Strictly comply with the following rules to prevent damage of the indoor units and human injury.
• Do not place heavy objects on the indoor unit. (Even when units are still packaged)
• Always carry the unit as packaged from the factory wherever possible. If carrying in the indoor unit unpacked by necessity,
be sure to use buffering cloth, etc. to prevent damaging the unit.
• To move the indoor unit, hold the hanging brackets (4 positions) only. Do not apply force to other parts (refrigerant pipe, drain
pan, foamed parts, or resin parts etc.).
• To be carried by two or more people. Do not strap the unit in positions other than stated.

When it is not possible to achieve a natural downward slope on the
drain pipe, you can create a vertical lift (Drain up) on the pipe.
• Set the height of the drain pipe within 850 mm from the bottom
surface of the ceiling.
• The drain pipe should be piped from the drain pipe connecting
port horizontally for a maximum of 300 mm and then piped
vertically.
• After piping the vertical lift, ensure the pipework is set to a
downward gradient.
After completion of drain piping, check water drains away and that no water leaks from any of the connecting parts. At the same time
check for any abnormal sounds from the drain pump.
Ensure drainage is checked during cooling mode.
When the electric work has finished:
• Before installing the ceiling panel, pour water as shown in the following figure, check water drains from the drain pipe connecting
port (Transparent) in COOL mode and then check there are no water leaks from the drain pipes.
When the electric work has not finished:
• Pull out the float switch connector (3P: Red) from P.C. board
connector (CN34: Red) of the electric parts box. (Ensure the
power is turned off.)
• Connect the single-phase 220-240V, 1N, 50 Hz power to the
terminal blocks (1) and (2).
• Pour water referring to the figure. (Amount: 1500 cc to 2000 cc)
• When the power is turned on, the drain pump motor drives
automatically.
Check water is drained from the drain pipe connecting port
(Transparent), and then check there is no water leak from the
drain pipes.
• After checking for water leaks on the drain, turn off the power
supply, and re-attach the float switch connector to the original
position (CN34) on the P.C. board and refit the electric parts box.

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.
3. Flare nut and flare works are different from those of the conventional refrigerant.
Take out the flare nut attached to the main unit of the air conditioner, and use it.
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.
• Projection margin in flaring: B (Unit: mm)
Rigid (Clutch type)
Imperial (Wing nut type)
• Flaring diam. meter size : A (Unit: mm)
* In the case of flaring for R410A with the conventional flare tool, pull it approx. 0.5 mm further out than that for R22 to adjust to the
specified flare size. The copper pipe gauge is useful for adjusting the projection margin size.
6 REFRIGERANT PIPING AND EVACUATING
Refrigerant piping
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)

Tightening connection
(Unit: N·m)
• Tightening torque of flare pipe connections.
Pressure of R410A is higher than that of R22. (Approx. 1.6 times) Therefore, using a torque wrench, tighten the flare pipe
connecting sections which connect the indoor and outdoor units of the specified tightening torque. Incorrect connections may cause
not only a gas leak, but also a trouble of the refrigeration cycle.
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.
CAUTION
• Do not apply excessive torque. Otherwise, the nut may crack depending on the conditions.
