• 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 to the customer
how to use and maintain the unit.
• 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
Power supply cord of outdoor unit shall be 2.5 mm2(H07RN-F or 60245IEC66) polychloroprene sheathed flexible cord.
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 18. 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 electric shock.
• Connect the connecting cable correctly.
If the connecting cable is connected by wrong way, electric 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.
• 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.
• Never 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.
Do not store it in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully for possible damage.
• Do not install in a place that can increase the vibration of the unit.
• To avoid personal injury, be careful when handling parts with sharp edges.
• Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.

EN
• When installing the air conditioner in a small room, provide appropriate measures to ensure that the concentration of
refrigerant in the room does not exceed the critical level should leakage occur.
It is not dangerous refrigerant; it has not toxicity or combustibility. However, a concentration above 0.3 kg/m³ as criterion still
causes suffocation. The volume of refrigerant charged to the Multi System air conditioner is more than the volume charged to
a conventional individual system.
• Install the air conditioner securely in a location where the weight of the unit can be sustained 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 may generate.
• When wiring, use the specified cables and connect the terminals securely to prevent external forces applied to the cable
from affecting 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 subject to a risk of exposure to combustible gas.
Otherwise, the combustible gas leaks, stays around the unit and 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.

The air supply ducting work is classified into two ways, one is branched by the square ducts, and the other is branched by the round
ducts. (Be sure to divide the air supply duct into three or more branches.)
Square duct
In case of using the square duct, apply the thermal insulator of thickness by 25 mm or more to the duct board. For the thermal
insulator, use high-density glass wool of weight by 64kg/m3.
Round duct
In case of using the round duct, use the thermal insulator of thickness by 25 mm or more and inner diameter by 150 mm or more to
the duct board. (If the inner diameter is not enough, resistance generates, 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 weight by 24 kg/m3or equivalent.
1. Supply air side
1. Using 6 screws, mount the flange to the supply air port of the indoor unit. (Fig. 1)
2. Make the square duct according to inner dimension of the flange. (A x B)
Use a glass wool board with inside/outside finishing by 25 mm-thickness and 64 kg/m3-density.
3. Connect the flange and each type of duct. (Fig. 2)

General cautions
1. Considering installation places of indoor unit and supply chamber, and structure of the building, 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 by setting size
up to the air supply chamber or by setting length to the first branch as long as possible (Min. 200 mm or longer) so that an even
air volume can be obtained.
Especially, when setting the branching point just after air supplying of the indoor unit, air concentrates at the center part and air is
difficult to flow to the ducts at both sides.
3. Connect each connecting section surely, and apply sufficient thermal insulation.
In this model which the duct is branched in the ceiling, compared with the general 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 exposure of the metal connecting section or leaking portion of the cooling
air may cause a trouble such as falling of water drop.
4. Thermal insulation of screwing sections is necessary.
Avoid dewing by applying thermal insulation to 6 screws which fix the duct flange of the air supply chamber.
• For duct parts, the flexible branch duct (thermal insulation, 25 mm or more thickness) is recommended.
• Adjust the duct length to 6 m or less even for straight pipe, and avoid sudden bending (part resistance is large.) if bending.

• For laying pipes under ground, use hard vinyl chloride pipe. (Inner diam. 20 or 25 mm)
• Set drain side of pipe at downward slope. (1/100 or more)
• Be sure to apply thermal insulation (foaming polyethylene, 10 mm-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.
• Support the piping with hanging bracket so that force is not applied to
connection sections of pipe and pipe is not waved with connected pipes.
• As shown in the figure, set the collective piping such as the ceiling duct so that
waste water does not back up from the main pipe.
NOTE
• Do not make slack or trap at halfway of pipes.
• Set pipes so that the end of drain pipe is not dipped in water, and also keep
space with 50 mm or more to the ground.
• After piping work, check 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.
• Insert the drain hose completely into the connecting port of the drain pan.
• Apply thermal insulation surely to the drain hose with elbow thermal insulation cover.
For drain-up kit installation.
Refer to the installation manual supplied with the drain-up kit.

1. If the outdoor units are to be mounted on a wall, make sure that the platform supporting 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 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.
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 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
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.
(Unit: N·m)
• Tightening torque for connection of flare pipe
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.
CAUTION
• Do not apply excess torque. Otherwise, the nut may crack depending on the conditions.
