1 PRECAUTIONS FOR SAFETY
Power supply cord of Outdoor unit shall be 2.5mm²(H07RN-F or 245 IEC66) polychloroprene sheathed flexible
cord.
•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 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.
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 cable correctly.
If the connecting cable is connected by wrong way, electric parts may be damaged.
•When moving the air-conditioner for installing it in another place again, be very careful not
to get the specified refrigerant with any other gaseous body 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 resultingly causes burst of the pipe and injuries on persons.
CAUTION To Disconnect the Appliance from the Main Power Supply.
This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a
contact separation of at least 3 mm.
If this is not possible, a power supply plug with grounding must be used. This plug must be easily accessible
after installation. The plug must be disconnected from the power supply socket in order to disconnect the
appliance completely from the mains.
The installation fuse (25A D type ) must be used for the power supply line of this conditioner.
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 is easy to absorb water, oxidizing membrane or oil, and its pressure is
approx. 1.6 times of refrigerant R22. Accompanied with adoption of the new refrigerant, refrigerating oil has
been also changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter into the refrigerating cycle of new refrigerant air conditioner.
To prevent from mixing of refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the
main unit or installation tools are different 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 materials with high pressure-tight force, which were made for
R410A only, so that water or dust does not enter. Moreover, do not use the existing piping because there are
problems about pressure-tight force and impurity it.

•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.
•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 0.3kg/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.
•The electrical work must be performed by a qualified electrician in accordance with the
Installation Manual. Make sure the air conditioner uses an exclusive circuit.
An insufficient circuit capacity or inappropriate installation may cause fire.
•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.
•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 combustible
gas.
Otherwise, the combustible gas leaks, stays around the unit and a fire may occur.

2 SELECTION OF INSTALLATION PLACE
WARNING
•Install the air conditioner where there is sufficient strength to withstand the weight of the unit.
If the strength is not sufficient, the unit may fall down resulting in injury.
•Install the air conditioner at a position keeping the height by 2.5m or more from the floor.
If you insert your hands or others directly into the unit during running of the air conditioner, 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 combustible gas.
Otherwise, the combustible gas leaks, stays around the unit and 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.
•Place where a sufficient servicing space can be ensured for safe maintenance and check.
•Place where drained water will not cause any problem.
•Make sure that the user cannot access the unit main body after the installation.
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 easy to transmit.
(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 Reference
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.)
4 AIR DUCTING WORK
Connecting method of the duct
1. Supply air side
Using 6 screws, mount the flange to the supply air port of the indoor unit. (Fig. 1)
Make the square duct according to inner dimension of the flange. A x B .
Use a glass wool board with inside/outside finishing by 25mm-thickness and 64kg/m³-density.
Connect the flange and each type of duct. (Fig. 2)
In case of using the square duct, apply the thermal
insulator of thickness by 25mm or more to the duct
board. For the thermal insulator, use high-density
glass wool of weight by 64kg/m3.
In case of using the round duct, use the thermal
insulator of thickness by 25mm or more and inner
diameter by 150mm 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 24kg/m3 or
equivalent.

Points at installation work
nGeneral 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:
200mm 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, 25mm or more thickness) is recommended.
•Adjust the duct length to 6m or less even for straight pipe, and avoid sudden bending (Part resistance is large.)

5 DRAIN PIPING WORK
Piping material
•For laying pipes under ground, use hard vinyl
chloride pipe. (Inner diam. 20 or 25mm)
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.
•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.
NOTES :
•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 50mm 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.
Connection of the drain hose
•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.

6 REFRIGERANT PIPING
Refrigerant Piping
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.
CAUTION
IMPORTANT 4 POINTS FOR PIPING WORK
1. Take away 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)
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 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.
CAUTION
•Do not apply excess 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.

Do not use the refrigerant in the outdoor unit.
For details, see the manual of vacuum pump.
Use a vacuum pump
Be sure to use a vacuum pump with counter-flow
prevention function so that inside oil of the pump does
not flow backward into pipes of the air conditioner
when the pump stops.
1. Connect the charge hose from the manifold valve to
the service port of the gas side packed valve.
2. Connect the charge hose to the port of vacuum
pump.
3. Open fully the low pressure side handle of the
gauge manifold valve.
4. Operate the vacuum pump to start for evacuating.
Perform evacuating for about 35 minutes if the
piping length is total 70 meters.
(25 minutes for total 50 meters)
(assuming a pump capacity of 27 liters per minute.)
Then confirm that the compound pressure gauge
reading is –101 kPa ( –76 cmHg).
5. Close the low pressure side valve handle of gauge
manifold.
6. Open fully the valve stem of the packed valves
(both sides of Gas and Liquid).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
