The specifications shown in the above table are for units without heaters. For units with heaters, refer

to the installation instructions or the construction instructions of the indoor unit.

Switchgear of Circuit breaker capacity which is calculated from MAX. over current should be chosen

along the regulations in each country.

The cable specifications are based on the assumption that a metal or plastic conduit is used with no

more than three cables contained in a conduit and a voltage drop is 2%. For an installation falling

outside of these conditions, please follow the internal cabling regulations. Adapt it to the regulation

in effect in each country.

SAFETY PRECAUTIONS

WARNING

• Read the “SAFETY PRECAUTIONS” carefully first of all and strictly follow it

during the installation work in order to protect yourself.

• The precautionary items mentioned below are distinguished into two levels,

and .

: Wrong installation would cause serious consequences such

as injuries or death.

: Wrong installation might cause serious consequences

depending on circumstances.

Both mentions the important items to protect your health and safety so strictly

follow them by any means.

• Be sure to confirm no anomaly on the equipment by commissioning after com-

pleted installation and explain the operating methods as well as the maintenance

methods of this equipment to the user according to the owner’s manual.

• Keep the installation manual together with owner’s manual at a place where

any user can read at any time. Moreover if necessary, ask to hand them to a

new user.

• For installing qualified personnel, take precautions in respect to themselves by

using suitable protective clothing, groves, etc., and then perform the

installation works.

• Please pay attention not to fall down the tools, etc. when installing the unit at

the high position.

• If unusual noise can be heard during operation, consult the dealer.

• The meanings of “Marks” used here are as shown on the right:

• This installation manual illustrates the method of installing an indoor

unit.

• For electrical wiring work, please see instructions set out on the

backside.

• For outdoor unit installation and refrigerant piping, please refer to the

installation manual that comes with your outdoor unit.

• A wired remote control unit is supplied separately as an optional part.

• When install the unit, be sure to check whether the selection of

installation place, power supply specifications, usage limitation (piping

length, height differences between indoor and outdoor units, power

supply voltage and etc.) and installation spaces.

Never do it under any

circumstances.

Always do it according to the

instruction.

CAUTIONWARNING

CAUTION

WARNING

• Installation must be carried out by the qualified installer.

If you install the system by yourself, it may cause serious trouble such as

water leaks, electric shocks, fire and personal injury, as a result of a

system malfunction.

• Install the system in full accordance with the installation manual.

Incorrect installation may cause bursts, personal injury, water leaks, electric

shocks and fire.

• Be sure to use only for household and residence.

If this appliance is installed in inferior environment such as machine shop

and etc., it can cause malfunction.

• Use the original accessories and the specified components for

installation.

If parts other than those prescribed by us are used, It may cause water

leaks, electric shocks, fire and personal injury.

• Install the unit in a location with good support.

Unsuitable installation locations can cause the unit to fall and cause

material damage and personal injury.

• Ventilate the working area well in the event of refrigerant leakage

during installation.

If the refrigerant comes into contact with naked flames, poisonous gas is

produced.

• When installing in small rooms, take prevention measures not to

exceed the density limit of refrigerant in the event of leakage,

referred by the formula (accordance with ISO5149).

If the density of refrigerant exceeds the limit, please consult the dealer and

install the ventilation system, otherwise lack of oxygen can occur, which

can cause serious accident.

• After completed installation, check that no refrigerant leaks from

the system.

If refrigerant leaks into the room and comes into contact with an oven or

other hot surface, poisonous gas is produced.

• Use the prescribed pipes, flare nuts and tools for R410A.

Using existing parts (for R22 or R407C) can cause the unit failure and

serious accidents due to burst of the refrigerant circuit.

• Tighten the flare nut by torque wrench with specified method.

If the flare nut were tightened with excess torque, this may cause burst and

refrigerant leakage after a long period.

• The electrical installation must be carried out by the qualified

electrician in accordance with “the norm for electrical work” and

“national wiring regulation”, and the system must be connected to

the dedicated circuit.

Power supply with insufficient capacity and incorrect function done by

improper work can cause electric shocks and fire.

• Be sure to shut off the power before starting electrical work.

Failure to shut off the power can cause electric shocks, unit failure or

incorrect function of equipment.

• Be sure to use the cables conformed to safety standard and cable

ampacity for power distribution work.

Unconformable cables can cause electric leak, anomalous heat production

or fire.

• This appliance must be connected to main power supply by means

of a circuit breaker or switch (fuse:20A) with a contact separation of

at least 3mm.

• When plugging this appliance, a plug conforming to the norm

IEC60884-1 must be used.

• Use the prescribed cables for electrical connection, tighten the

cables securely in terminal block and relieve the cables correctly to

prevent overloading the terminal blocks.

Loose connections or cable mountings can cause anomalous heat

production or fire.

• Arrange the wiring in the control box so that it cannot be pushed up

further into the box. Install the service panel correctly.

Incorrect installation may result in overheating and fire.

• Be sure to switch off the power supply in the event of installation,

inspection or servicing.

If the power supply is not shut off, there is a risk of electric shocks, unit

failure or personal injury due to the unexpected start of fan.

CAUTION

• Use the circuit breaker of correct capacity. Circuit breaker should

be the one that disconnect all poles under over current.

Using the incorrect one could cause the system failure and fire.

• Earth leakage breaker must be installed.

If the earth leakage breaker is not installed, it can cause electric shocks.

• Install isolator or disconnect switch on the power supply wiring in

• Install the drainage pipe to run off drainage securely according to

the installation manual.

Incorrect installation of the drainage pipe can cause dropping water into the

room and damaging personal property.

• Be sure to install the drainage pipe with descending slope of 1/100

or more, and not to make traps and air-bleedings.

Check if the drainage runs off securely during commissioning and ensure

the space for inspection and maintenance.

• Secure a space for installation, inspection and maintenance

specified in the manual.

Insufficient space can result in accident such as personal injury due to

falling from the installation place.

• For installation work, be careful not to get injured with the heat

exchanger, piping flare portion or screws etc.

• Be sure to insulate the refrigerant pipes so as not to condense the

ambient air moisture on them.

Insufficient insulation can cause condensation, which can lead to moisture

damage on the ceiling, floor, furniture and any other valuables.

• When perform the air conditioner operation (cooling or drying

operation) in which ventilator is installed in the room. In this case,

using the air conditioner in parallel with the ventilator, there is the

possibility that drain water may backflow in accordance with the

room lapse into the negative pressure status. Therefore, set up the

opening port such as incorporate the air into the room that may

appropriate to ventilation (For example; Open the door a little). In

addition, just as above, so set up the opening port if the room lapse

into negative pressure status due to register of the wind for the high

rise apartment etc.

• Be sure to perform air tightness test by pressurizing with nitrogen

gas after completed refrigerant piping work.

If the density of refrigerant exceeds the limit in the event of refrigerant

leakage in the small room, lack of oxygen can occur, which can cause

serious accidents.

combustible gases can occur.

If leaked gases accumulate around the unit, it can cause fire.

• Do not install the unit where corrosive gas (such as sulfurous acid

gas etc.) or combustible gas (such as thinner and petroleum gases)

can accumulate or collect, or where volatile combustible

substances are handled.

Corrosive gas can cause corrosion of heat exchanger, breakage of plastic

parts and etc. And combustible gas can cause fire.

• Do not use the indoor unit at the place where water splashes may

occur such as in laundries.

Since the indoor unit is not waterproof, it can cause electric shocks and fire.

• Do not install nor use the system close to the equipment that

generates electromagnetic fields or high frequency harmonics.

Equipment such as inverters, standby generators, medical high frequency

equipments and telecommunication equipments can affect the system, and

cause malfunctions and breakdowns. The system can also affect medical

equipment and telecommunication equipment, and obstruct its function or

cause jamming.

• Do not place any variables which will be damaged by getting wet

under the indoor unit.

When the relative humidity is higher than 80% or drainage pipe is clogged,

condensation or drainage water can drop and it can cause the damage of

valuables.

• Do not install the remote control at the direct sunlight.

It can cause malfunction or deformation of the remote control.

• Do not use the unit for special purposes such as storing foods,

cooling precision instruments and preservation of animals, plants or

art.

It can cause the damage of the items.

• Do not use any materials other than a fuse with the correct rating in

the location where fuses are to be used.

Connecting the circuit with copper wire or other metal thread can cause

unit failure and fire.

• Do not touch any buttons with wet hands.

It can cause electric shocks.

• Do not touch any refrigerant pipes with your hands when the

system is in operation.

During operation the refrigerant pipes become extremely hot or extremely

cold depending the operating condition, and it can cause burn injury or

frost injury.

• Carry out the electrical work for ground lead with care.

Do not connect the ground lead to the gas line, water line, lightning conductor or telephone line’s ground lead. Incorrect grounding can cause unit faults

such as electric shocks due to short-circuiting.

• Do not put the drainage pipe directly into drainage channels where

poisonous gases such as sulphide gas can occur.

Poisonous gases will flow into the room through drainage pipe and

seriously affect the user’s health and safety. This can also cause the

corrosion of the indoor unit and a resultant unit failure or refrigerant leak.

• Ensure that no air enters in the refrigerant circuit when the unit is

installed and removed.

If air enters in the refrigerant circuit, the pressure in the refrigerant circuit

becomes too high, which can cause burst and personal injury.

• Do not processing, splice the power cord, or share a socket with

other power plugs.

This may cause fire or electric shock due to defecting contact, defecting

insulation and over-current etc.

• Do not bundling, winding or processing for the power cord. Or, do

not deforming the power plug due to tread it.

This may cause fire or heating.

• Do not vent R410A into the atmosphere : R410A is a fluorinated

greenhouse gas, covered by the Kyoto Protocol with Groval

Warming Potential (GWP)=1975.

• Do not run the unit with removed panels or protections.

2) Portage

3) Selecting the installation location

Wooden pallet

• Deliver the unit as close as possible to the installation site before removing it from

the packaging.

• When you have to unpack the unit for a compelling reason before you haul it to

the installation point, hoist the unit with nylon slings or ropes and protection pads

so that you may not damage the unit.

• The right hand side of the unit as viewed from the front (diffuser side) is heavier.

A person carrying the right hand side must take heed of this fact. A person

carrying the left hand side must hold with his right hand the handle provided on

the front panel of the unit and with his left hand the corner column section.

(1) If the unit is installed in the area where the snow will accumulate, following measures are required.

The bottom plate of unit and intake, outlet may be blocked by snow.

1 Install the unit on the base so that the bottom is

higher than snow cover surface.

Since drain water generated by defrost control may freeze, following measures are required.

• Do not execute drain piping work by using a drain elbow and drain grommets (optional parts).

[Refer to Drain piping work.]

2 Install the unit under eaves or provide the roof

on site.

Be careful of the following conditions and choose an installation place.

• Where air is not trapped.

• Where the installation fittings can be firmly installed.

• Where wind does not hinder the intake and outlet pipes.

• Out of the heat range of other heat sources.

• A place where stringent regulation of electric noises is applicable.

• Where it is safe for the drain water to be discharged.

• Where noise and hot air will not bother neighboring residents.

• Where snow will not accumulate.

• Where strong winds will not blow against the outlet pipe.

• A place where no TV set or radio receiver is placed within 1m.

(If electrical interference is caused, seek a place less likely to cause the problem)

• If a operation is conducted when the outdoor air temperature is –5°C lower, the outdoor unit should be

installed at a place where it is not influenced by natural wind.

• Where it is likely that the unit is subjected to strong winds, provide wind guards according to the

following guidelines. Strong winds can cause performance degradation, an accidental stop due to a rise of

high pressure and a broken fan.

4) Caution about selection of installation location

Notabilia as a unit designed for R410A

• Do not use any refrigerant other than R410A. R410A will rise to pressure about 1.6 times higher than that of a conventional refrigerant.

A cylinder containing R410A has a pink indication mark on the top.

• A unit designed for R410A has adopted a different size indoor unit operation valve charge port and a different size check joint provided in the unit to prevent the charging of a wrong refrigerant by mistake.

The processed dimension of the flared part of a refrigerant pipe and a flare nut’s parallel side measurement have also been altered to raise strength against pressure.

Accordingly, you are required to arrange dedicated R410A tools listed in the table on the left before installing or servicing this unit.

• Do not use a charge cylinder. The use of a charge cylinder will cause the refrigerant composition to change, which results in performance degradation.

• In charging refrigerant, always take it out from a cylinder in the liquid phase.

• All indoor units must be models designed exclusively for R410A. Check connectable indoor unit models in a catalog, etc. (A wrong indoor unit, if connected into the system, will impair proper system operation)

• Read the “SAFETY PRECAUTIONS” carefully first of all and strictly follow it during the installation work in order

to protect yourself.

• The precautionary items mentioned below are distinguished into two levels, and .

: Wrong installation would cause serious consequences such as injuries or death.

: Wrong installation might cause serious consequences depending on circumstances.

Both mentions the important items to protect your health and safety so strictly follow them by any means.

• Be sure to confirm no anomaly on the equipment by commissioning after completed installation and explain the

operating methods as well as the maintenance methods of this equipment to the user according to the owner’s

manual.

• Keep the installation manual together with owner’s manual at a place where any user can read at any time.

Moreover if necessary, ask to hand them to a new user.

• For installing qualified personnel, take precautions in respect to themselves by using suitable protective

clothing, groves, etc., and then perform the installation works.

• Please pay attention not to fall down the tools, etc. when installing the unit at the high position.

earthquakes and strong winds.

Unsuitable installation locations can cause the unit to fall and cause material

damage and personal injury.

• Ventilate the working area well in the event of refrigerant leakage during

installation.

If the refrigerant comes into contact with naked flames, poisonous gas is produced.

• Use the prescribed pipes, flare nuts and tools for R410A.

Using existing parts (for R22 or R407C) can cause the unit failure and serious

accidents due to burst of the refrigerant circuit.

• Tighten the flare nut by torque wrench with specified method.

If the flare nut were tightened with excess torque, this may cause burst and

refrigerant leakage after a long period.

• Do not open the operation valves for liquid line and gas line until

completed refrigerant piping work, air tightness test and evacuation.

If the compressor is operated in state of opening operation valves before

completed connection of refrigerant piping work, air can be sucked into refrigeran t

circuit, which can cause bust or personal injur y due to anomalously high pressure

in the refrigerant.

• The electrical installation must be carried out by the qualified electrician

in accordance with “the norm for electrical work” and “national wiring

regulation”, and the system must be connected to the dedicated circuit.

Power supply with insufficient capacity and incorrect function done by improper

work can cause electric shocks and fire.

• Be sure to shut off the power before starting electrical work.

Failure to shut off the power can cause electric shocks, unit failure or incorrect

function of equipment.

• Be sure to use the cables conformed to safety standard and cable

ampacity for power distribution work.

Unconformable cables can cause electric leak, anomalous heat production or fire.

• This appliance must be connected to main power supply by means of a

circuit breaker or switch (fuse:20A) with a contact separation of at least

3mm.

• Arrange the wiring in the control box so that it cannot be pushed up

further into the box. Install the service panel correctly.

Incorrect installation may result in overheating and fire.

• Use the prescribed cables for electrical connection, tighten the cables

securely in terminal block and relieve the cables correctly to prevent

overloading the terminal blocks.

Loose connections or cable mountings can cause anomalous heat production or fire.

• Be sure to fix up the service panels.

Incorrect fixing can cause electric shocks or fire due to intrusion of dust or water.

• Be sure to switch off the power supply in the event of installation,

inspection or servicing.

If the power supply is not shut off, there is a risk of electric shocks, unit failure or

personal injury due to the unexpected start of fan.

• Stop the compressor before removing the pipe after shutting the

service valve on pump down work.

If the pipe is removed when the compressor is in operation with the service valve

open, air would be mixed in the refrigeration circuit and it could cause explosion

and injuries due to abnormal high pressure in the cooling cycle.

• Only use prescribed optional parts. The installation must be carried out

by the qualified installer.

If you install the system by yourself, it can cause serious trouble such as water

leaks, electric shocks, fire.

• Be sure to wear protective goggles and gloves while at work.

• Earth leakage breaker must be installed.

If the earth leakage breaker is not installed, it can cause electric shocks.

• Ensure that no air enters in the refrigerant circuit when the unit is

installed and removed.

If air enters in the refrigerant circuit, the pressure in the refrigerant circuit

becomes too high, which can cause burst and personal injury.

•

Do not processing, splice the power cord, or share a socketwithother power plugs.

This may cause fire or electric shock due to defecting contact, defecting insulation

and over-current etc.

• Do not bundling, winding or processing for the power cord. Or, do not

deforming the power plug due to tread it.

This may cause fire or heating.

• Do not run the unit with removed panels or protections.

Touching rotating equipments, hot surfaces or high voltage parts can cause

personal injury due to entrapment, burn or electric shocks.

• Do not perform any change of protective device itself or its setup

condition.

The forced operation by short-circuiting protective device of pressure switch and

temperature controller or the use of non specified component can cause fire or

burst.

• Use the circuit breaker for all pole correct capacity. Circuit breaker

should be the one that disconnect all poles under over current.

Using the incorrect circuit breaker, it can cause the unit malfunction and fire.

• Install isolator or disconnect switch on the power supply wiring in

accordance with the local codes and regulations.

The isolator should be locked in OFF state in accordance with EN60204-1.
