PIPE INSTALLATION

1. FLARING

(1) Cut the connection pipe to the necessary length with a pipe cutter.

(2) Hold the pipe downward so that cuttings will not enter the pipe and

remove the burrs.

(3) Insert the ﬂ are nut (always use the ﬂ are nut attached to the indoor

and outdoor units respectively) onto the pipe and perform the ﬂ are

processing with a ﬂ are tool.

Use the special R410A ﬂ are tool, or the conventional ﬂ are tool.

Check if [L] is ﬂ ared uniformly and

is not cracked or scratched. B

Pipe

Width across

ﬂ ats

When using conventional ﬂ are tools to ﬂ are R410A pipes, the dimension

A should be approximately 0.5 mm more than indicated in the table (for

ﬂ aring with R410A ﬂ are tools) to achieve the speciﬁ ed ﬂ aring. Use a

thickness gauge to measure the dimension A.

The pipes are shaped by your hands. Be careful not to collapse them.

Do not bend the pipes in an angle more than 90 °.

When pipes are repeatedly bend or stretched, the material will harden,

making it difﬁ cult to bend or stretch them any more. Do not bend or

stretch the pipes more than three times.

CAUTION

To prevent breaking of the pipe, avoid sharp bends.

Bend the pipe with a radius of curvature of 150 mm or over.

If the pipe is bent repeatedly at the same place, it will break.

2. BENDING PIPES

(3) When the ﬂ are nut is tightened properly by your hand, use a torque

wrench to ﬁ nally tighten it.

(2) Centering the pipe against port on the indoor unit, turn the ﬂ are nut

with your hand.

3. PIPE CONNECTION

Indoor unit

(1) Detach the caps and plugs from the pipes.

CAUTION

Be sure to apply the pipe against the port on the indoor unit

correctly. If the centering is improper, the ﬂ are nut cannot

be tightened smoothly. If the ﬂ are nut is forced to turn, the

threads will be damaged.

Do not remove the ﬂ are nut from the indoor unit pipe until

immediately before connecting the connection pipe.

STANDARD PARTS

function of the ﬂ oat switch, and may cause water leakage.

INSTALLATION WORK

Install the air conditioner as follows:

* For a 3-way outlet, make sure to perform the Function Setting on the

remote controller. Also, make sure to use the optional shutter panel to

block the outlet.

* The ceiling height cannot be set in the 3-way outlet mode. Therefore, do

not change the setting in the “Setting the Ceiling Height” at

FUNC-

TION SETTING.

* When the outlet is shut, be sure to install the optional Air outlet shut-

ter plate kit.

For the details of installation, please refer to Installation Manual of kit.

It is necessary to use seamless copper pipes and it is desirable that the

amount of residual oil is less than 40 mg/10 m. Do not use copper pipes

having a collapsed, deformed or discolored portion (especially on the interior

surface). Otherwise, the expansion valve or capillary tube may become

blocked with contaminants.

As an air conditioner using R410A incurs pressure higher than when

using conventional refrigerant, it is necessary to choose adequate materials.

Thicknesses of copper pipes used with R410A are as shown in the table.

Never use copper pipes thinner than that in the table even when it is

available on the market.

DANGER This mark indicates procedures which, if improperly performed, are most likely to result in the death of

or serious injury to the user or service personnel.

WARNING This mark indicates procedures which, if improperly performed, might lead to the death or serious injury

of the user.

CAUTION This mark indicates procedures which, if improperly performed, might possibly result in personal harm

to the user, or damage to property.

DANGER

Never touch electrical components immediately after the power supply has been turned off. Electrical shock may occur. After

turning off the power, always wait 5 minutes or more before touching electrical components.

This air conditioner uses new refrigerant HFC (R410A).

The basic installation work procedures are the same as conventional refrigerant models.

However, pay careful attention to the following points:

Since the working pressure is 1.6 times higher than that of conventional refrigerant models, some of the piping and installation

and service tools are special. (See the table below.)

Especially, when replacing a conventional refrigerant model with a new refrigerant R410A model, always replace the conven-

tional piping and ﬂ are nuts with the R410A piping and ﬂ are nuts.

Models that use refrigerant R410A have a different charging port thread diameter to prevent erroneous charging with con-

ventional refrigerant and for safety. Therefore, check beforehand. [The charging port thread diameter for R410A is 1/2 UNF 20

threads per inch.]

Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with refrigerant models. Also, when storing

the piping, securely seal the openings by pinching, taping, etc.

When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and always

charge from the liquid phase side whose composition is stable.

Special tools for R410A

Tool name Contents of change

Gauge manifold

Pressure is high and cannot be measured with a conventional gauge. To prevent erroneous mixing of other

refrigerants, the diameter of each port has been changed.

It is recommended the gauge with seals –0.1 to 5.3 MPa (–76 cmHg to 53 kgf/cm 2) for high pressure. –0.1 to

3.8 MPa (–76 cmHg to 38 kgf/cm2) for low pressure.

Charge hose To increase pressure resistance, the hose material and base size were changed.

Vacuum pump A conventional vacuum pump can be used by installing a vacuum pump adapter.

SELECTING AN INSTALLA-

TION LOCATION

Decide the mounting position with the customer as follows:

WARNING

Select installation locations that can properly support the weight

of the indoor unit. Install the units securely so that they do not

topple or fall.

CAUTION

Do not install the indoor unit in the following areas:

• Area with high salt content, such as at the seaside. It will deteriorate

metal parts, causing the parts to fail or the unit to leak water.

• Area ﬁ lled with mineral oil or containing a large amount of splashed

oil or steam, such as a kitchen. It will deteriorate plastic parts, caus-

ing the parts to fail or the unit to leak water.

• Area that generates substances that adversely affect the equipment,

such as sulfuric gas, chlorine gas, acid, or alkali. It will cause the

copper pipes and brazed joints to corrode, which can cause refriger-

ant leakage.

• Area that can cause combustible gas to leak, contains suspended

carbon fibers or flammable dust, or volatile inflammables such as

paint thinner or gasoline. If gas leaks and settles around the unit, it

can cause a ﬁ re.

• Area where animals may urinate on the unit or ammonia may be

generated.

Do not install where there is the danger of combustible gas leakage.

Do not install the unit near a source of heat, steam, or ﬂ ammable gas.

Install the indoor unit, outdoor unit, power supply cable, transmission

cable, and remote control cable at least 1 m away from a television or

radio receivers. The purpose of this is to prevent TV reception interfer-

ence or radio noise. (Even if they are installed more than 1 m apart,

you could still receive noise under some signal conditions.)

If children under 10 years old may approach the unit, take preventive

measures so that they cannot reach the unit.

Use the “Insulation kit for high humidity” (option), when the condition

under the roof is over 80% in humidity and over 30°C in temperature.

Otherwise, there is a risk of condensation on the ceiling.

(1) Install the indoor unit in a location having sufﬁ cient strength to sup-

port the weight of the indoor unit.

(2) The inlet and outlet ports should not be obstructed; the air should be

able to blow all over the room.

(3) Leave the space required to service the air conditioner.

(4) Locate where the air can be distributed evenly throughout the room

by the unit.

(5) Install the unit where connection to the outdoor unit is easy.

(6) Install the unit where the connection pipe can be easily installed.

(7) Install the unit where the drain pipe can be easily installed.

WARNING

When fastening the hangers, make the bolt positions

uniform.

WARNING

Perform ﬁ nal tightening by tightening the double nut ﬁ rmly.

WARNING

Electrical work must be performed in accordanc e with t his

Manual by a person certified under the national or regional

regulations. Be sure to use a dedicated circuit for the unit.

An insufﬁ cient power supply circuit or improperly performed electrical

work can cause serious accidents such as electric shock or ﬁ re.

Before starting work, check that power is not being supplied to the in-

door unit and outdoor unit.

Use the included transmission cables and power cables or ones speci-

ﬁ ed by the manufacturer. Improper connections, insufﬁ cient insulation,

or exceeding the allowable current can cause electric shock or ﬁ re.

For wiring, use the prescribed type of wires, connect them securely, mak-

ing sure that there are no external forces of the wires applied to the termi-

nal connections. Improperly connected or secured wires can cause seri-

ous accidents such as overheating the terminals, electric shock, or ﬁ re.

Do not modify the power cables, use extension cables, or use any

branches in the wiring. Improper connections, insufﬁ cient insulation, or

exceeding the allowable current can cause electric shock or ﬁ re.

Match the terminal block numbers and connection cable colors with those of the out-

door unit or branch box. Erroneous wiring may cause burning of the electric parts.

Securely connect the connection cables to the terminal blocks. In ad-

dition, secure the cables with wiring holders. Improper connections, ei-

ther in the wiring or at the ends of the wiring, can cause a malfunction,

electric shock, or ﬁ re.

Always fasten the outside covering of the connection cable with the

cable clamp. (If the insulator is chafed, electric leakage may occur.)

Securely install the electrical box cover on the unit. An improperly in-

stalled electrical box cover can cause serious accidents such as elec-

tric shock or ﬁ re through exposure to dust or water.

Install sleeves into any holes made in the walls for wiring. Otherwise,

a short circuit could result.

Install a earth (ground) leakage breaker. In addition, install the earth

(ground) leakage breaker so that the entire AC main power supply is

cut off at the same time. Otherwise, electric shock or ﬁ re could result.

Always connect the earth (ground) wire.

Improper earthing (grounding) work can cause electric shocks.

Install the remote controller cable and bus wire so as not to be direct

touched with your hand.

(1) Use ring terminals with insulating sleeves as shown in the ﬁ gure be-

low to connect to the terminal block.

(2) Securely clamp the ring terminals to the wires using an appropriate

tool so that the wires do not come loose.

(3) Use the speciﬁ ed wires, connect them securely, and fasten them so

that there is no stress placed on the terminals.

(4)

Use an appropriate screwdriver to tighten the terminal screws. Do not

use a screwdriver that is too small, otherwise, the screw heads may

be damaged and prevent the screws from being properly tightened.

(5)

Do not tighten the terminal screws too much, otherwise, the screws may break.

2INSTALLING DRAIN PIPE

Note: Install the drain pipe.

 Install the drain pipe with downward gradient (1/50 to 1/100) and so

there are no rises or traps in the pipe.



Use general hard polyvinyl chloride pipe (VP25) [outside diameter 32 mm (1-1/4”)]

and connect it with adhesive (polyvinyl chloride) so that there is no leakage.

 When the pipe is long, install supporters.

 Do not perform air bleeding.

 Always heat insulate the indoor side of the drain pipe.
