strong winds, typhoons, or earthquakes.

Improper installation may result in an accident such as air

conditioner falling.

Make certain that all electrical work is carried out by qualied

personnel according to the applicable legislation (note 1) and

this installation manual, using a separate circuit.

In addition, even if the wiring is short, make sure to use a wiring

that has sufcient length and never connect additional

wiring to make the length sufcient.

Insufcient capacity of the power supply circuit or improper

electrical construction may lead to electric shocks or a re.(note 1) applicable legislation means All international,

national and local directives, laws, regulations and/

or codes which are relevant and applicable for a

certain product or domain.

Earth the air conditioner.

Do not connect the earth wiring to gas or water piping,

lightning conductor or telephone earth wiring.

Incomplete earthing may cause electric shocks or a re.

Be sure to install an ear th leakage breaker.

Failure to do so may cause electric shocks and a re.

Disconnect the power supply before touching the electric

components.

If you touch the live part, you may get an electric shocks.

1. SAFETY PRECAUTIONS

This manual classies the precautions into WARNINGS and

CAUTIONS.

Be sure to follow all the precautions below: They are allimportant for ensuring safety.

WARNING............... Indicates a potentially hazardous

situation which, if not avoided,

could result in death or serious

injury.

CAUTION.................Indicates a potentially hazardous

situation which, if not avoided,

may result in minor or moderate

injury.

It may also be used to alert

against unsafe practices.

Please read the these "SAFETY CONSIDERATIONS"carefully before installing air conditioning unit and be sure to

install it correctly. After completing the installation, make surethat the unit operates properly during the start-up operation.

Please instruct the customer on how to operate the unit andkeep it maintained.

Also, inform customers that they should store this installationmanual along with the operation manual for future reference.

CAUTION

Install drain piping according to this installation manual to

ensure good drainage, and insulate the piping to prevent

condensation.

Improper drain piping may cause water leakage, make the

furniture get wet.

Install the air conditioner, power supply wiring, remote

controller wiring and transmission wiring at least 1 meter away

from televisions or radios to prevent image interference or noise.

(Depending on the radio waves, a distance of 1 meter may

not be sufcient to eliminate the noise.)

Install the indoor unit as far as possible from orescentlamps.

If a wireless remote controller kit is installed, the transmission

distance may be shorter in a room where an electronic

lighting type (inverter or rapid start type) uorescent lamp is

installed.

Do not install the air conditioner in places such as the

following:

1. Where there is mist of oil, oil spray or vapour for example

a kitchen.

Resin parts may deteriorate, and cause them to fall out or

water to leak.

2. Where corrosive gas, such as sulfurous acid gas, is

produced.

Corrosion of copper pipings or brazed parts may cause

the refrigerant to leak.

3. Where there is machinery which emits electromagnetic

waves.

Electromagnetic waves may disturb the control system,

and cause malfunction of the equipment.

4. Where ammable gases may leak, where carbon bre or

ignitable dust is suspended in the air or where volatileammables, such as thinner or gasoline, are handled.

If the gas should leak and remained around the air

conditioner, it may cause ignition.

The air conditioner is not intended for use in a potentially

explosive atomosphere.

2. BEFORE INSTALLATION

SPECIAL NOTICE PRODUCT

When unpacking and moving the indoor unit after

unpacked, do not apply force to the piping (refrigerant and

drain) and resin parts.

Make sure to check in advance that the refrigerant to be used

for installation work is R410A.

(The air conditioner will not properly operate if a wrong

refrigerant is used.)

For installation of the outdoor unit, refer to the installation

manual attached to the outdoor unit.

Do not throw away the accessories until the installation work

is completed.

After the indoor unit is carried into the room, to avoid the

indoor unit from getting damaged, take measures to protectthe indoor unit with packing materials.

(1) Determine the route to carry the unit into the room.

(2) Do not unpack the unit until it is carried to the installation

location.

Where unpacking is unavoidable, use a sling of soft

material or protective plates together with a rope when

lifting, to avoid damage or scratches to the indoor units.

Have the customer actually operate the air conditioner while

looking at the manual.

Instruct the customer how to operate the air conditioner

(particularly cleaning of the air lters, operation procedures,

and temperature adjustment).

Make sure that all wiring is secure, using the specied wiringsand ensuring that external forces do not act on the terminal

connections or wirings.

Incomplete connection or xing may cause an overheat or a re.

When wiring between the indoor and outdoor units, and wiring

the power supply, form the wirings orderly so that the controlbox lid can be securely fastened.

If the control box lid is not in place, overheat of the terminals,

electric shocks or a re may be caused.

If refrigerant gas leaks during installation work, ventilate the

area immediately.

Toxic gas may be produced if refrigerant gas comes into

contact with a re.

After completing the installation work, check to make sure

that there is no leakage of refrigerant gas.

Toxic gas may be produced if refrigerant gas leaks into the

room and comes into contact with a source of a re, such as

a fan heater, stove or cooker.

Never directly touch any accidental leaking refrigerant. This

could result in severe wounds caused by frostbite.

Be sure to switch off the unit before touching any electrical parts.

Do not allow children to climb on the outdoor unit and avoidplacing objects on the unit.Injury may result if the unit becomes loose and falls.

Make sure to provide for adequate measures in order to preventthat the outdoor unit be used as a shelter by small animals.

Small animals making contact with electrical parts can cause keep the area around the unit clean.

Install in a machine room that is free of moisture. The unit isdesigned for indoor use.

Disposal requirementsDismantling of the unit, treatment of the refrigerant, of oil and ofother parts must be done in accordance with relevant local andnational legislation.

The refrigerant R410A requires that strict precautions beobserved for keeping the system clean, dry and tightly sealed.

Clean and dryStrict measures must be taken to keep impurities(including SUNISO oil and other mineral oils as well asmoisture) out of the system.

Tightly sealedR410A contains no chlorine, does not destroy the ozonelayer and so does not reduce the earth's protection against

harmful ultraviolet radiation. R410A will contribute only slightly

to the greenhouse effect if released into the atmosphere.

than previously. Since R410A is a mixed refrigerant, the

required additional refrigerant must be charged in its liquid state.(If the system is charged with refrigerant in its gaseous state,due to composition change, the system will not functionnormally). The indoor unit is designed for R410A use.See the catalogue for indoor unit models that can be

connected. (Normal operation is not possible when connectingunits that are originally designed for other refrigerants.)

WARNING

The indoor unit must be securely installed on a place

that can withstand the mass.

If the strength is insufcient, the indoor unit may fall down

and cause injuries.

6. REFRIGERANT PIPING WORK

For the outdoor unit refrigerant piping, refer to the installation

manual attached to the outdoor unit.

Carry out insulation of both gas and liquid refrigerant piping

securely. If not insulated, it may cause water leakage. For

gas piping, use insulation material of which heat resistant

temperature is not less than 120C. For use under high

humidity, strengthen the insulation material for refrigerant

piping. If not strengthened, the surface of insulation material

may sweat.

Before installation work, make sure that the refrigerant is

R410A. (Unless the refrigerant is R410A, the normal

operation cannot be expected.)

CAUTION

This air conditioner is a dedicated model for new refrigerant

R410A. Make sure to meet the requirements shown right

and carry out installation work.

Use dedicated piping cutters and aring tools for R410A.

When making a are connection, coat the d inner

surface only with ether oil or ester oil.

Use only the are nuts attached to the air conditioner. If

other nuts are used, it may cause refrigerant leakage.

To prevent contamination or moisture from getting into the

piping, take measures such as pinching or taping the

pipings.

Do not mix substance other than the specied refrigerant

such as air into the refrigeration circuit.

If the refrigerant leaks during the work, ventilate the room.

5. INSTALLATION OF THE INDOOR UNIT

It is easy to attach the optional parts before installing the

indoor unit. Refer to also the installation manual attached

to the optional parts.

For installation, use the attached installation parts and

parts.

(1) Fix the hanger to the hanging bolt. (Refer to Fig. 10)

CAUTION

For safety, make sure to use a washer for hanger (3)

(accessory) and x by double nuts rmly.

(2) Lift up the indoor unit, slide from the front and put the

hanger installing bolt (M8) into the securely for temporary

hanging.(Refer to Fig. 11)

(3) Tighten the hanger xing screws (M5) at 2 places, which

were removed, as they were before.

(Refer to Fig. 11)

It is necessary to prevent misalignment of the indoor unit.

(4) Tighten the hanger installing bolts (M8) at 4 places

securely.(Refer to Fig. 11)

(5) When hanging the indoor unit, make sure to use the level to

have better drainage and install it horizontally. Also, if it is

possible at the installation site, install so that the drain

piping side is slightly lower.(Refer to Fig. 12)

CAUTION

Setting the indoor unit at an angle opposite to the drain

piping might cause a water leakage.

Do not insert materials other than that into

the clearance between the hanger and the washer for

hanger (3).

Unless the washers are properly attached, the hanging

bolts may come off from the hanger.

CAUTION

Insulation of eld piping must be carried out up to the

connection inside the casing. If the piping is exposed to the

atmosphere, it may cause sweating or burn due to touching

the piping, electric shocks or a re due to the wiring touchingthe piping.

After leak test, referring to Fig. 15, insulate both the gas and

liquid piping connection with the attached joint insulating

material (6) and (7) to prevent the piping from getting

exposed. Then, tighten the both ends of insulating material

with the clamp (4).

Wrap the sealing material (Small) (9) around the joint insulating

material (6) nut section), only the gas piping side.

Make sure to bring the seam of joint insulating material (6)

and (7) to the top.

Remove the stay for packing and delivering (reinforcing

plate) before refrigerant piping work.

(Refer to Fig. 18)

The refrigerant is pre-charged in the outdoor unit.

When connecting the pipings to the air conditioner, make sure

to use a spanner and a torque wrench as shown in Fig.13.For the dimension of ared part, refer to the Table 1.

When making a are connection, coat the ared inner surface

only with ether oil or ester oil. (Refer to Fig. 14)Then, turn theare nut 3 to 4 times with your hand and screw in the nut.

For the tightening torque, refer to the Table 1.

Table 1

CAUTION

Do not have oil adhere to the screw ng part of resin

parts.

If oil adheres, it may weaken the strength of screwed part.

Do not tighten e nuts too tight.

If a nut cracks, the refrigerant may leak.

If there is no torque wrench, use Table 2 as a rule of thumb.

When tightening a nut with a spanner harder andharder, there is a point where the tightening torque suddenly

increases. From that position, tighten the nut additionally the

angle shown in Table 2. After the work is nished, check

securely that there is no gas leak. If the nut is not tightened

as instructed, it may cause slow refrigerant leak and result in

malfunction (such as does not cool or heat).
