1. SAFETY PRECAUTIONS

Be sure to read this Manual thoroughly before installation.

The warnings and precautions indicated in this Manual contain important information

pertaining to your safety. Be sure to observe them.

Hand this Manual, together with the Operating Manual, to the customer. Request the

customer to keep them on hand for future use, such as for relocating or repairing the unit.

After installation, explain correct operation to the customer, using the operating manual.

WARNING This mark indicates procedures which, if improperly performed,

might lead to the death or serious injury of the user.

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.

Request your dealer or a professional installer to install the indoor unit in accordance

with this Installation Manual. An improperly installed unit can cause serious accidents

such as water leakage, electric shock, or ﬁ re. If the indoor unit is installed in disregard

of the instructions in the Installation Manual, it will void the manufacturer’s warranty.

Do not turn ON the power until all work has been completed. Turning ON the power

before the work is completed can cause serious accidents such as electric shock or ﬁ re.

If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant

comes in contact with a ﬂ ame, it produces a toxic gas.

Installation work must be performed in accordance with national wiring standards by

authorized personnel only.

During installation, make sure that the refrigerant pipe is attached ﬁ rmly before you run

the compressor.

Do not operate the compressor under the condition of refrigerant piping not attached

properly with 2-way or 3-way valve open. This may cause abnormal pressure in the

refrigeration cycle that leads to breakage and even injury.

When installing and relocating the air conditioner, do not mix gases other than the

speciﬁ ed refrigerant (R410A) to enter the refrigerant cycle.

If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to

an abnormally high value and cause breakage, injury, etc.

Do not remove the connection pipe while the compressor is in operation with 2-way or

3-way valve open.

This may cause abnormal pressure in the refrigeration cycle that leads to breakage and

even injury.

For the air conditioner to operate satisfactorily, install it as outlined in this installation

manual.

Connect the indoor unit and outdoor unit with the air conditioner piping and cable

available standards parts.

This installation manual describes the correct connections using the installation set

available from our standard parts.

Also, do not use an extension cable.

Do not purge the air with refrigerants but use a vacuum pump to vacuum the

installation.

There is not extra refrigerant in the outdoor unit for air purging.

Use a vacuum pump for R410A exclusively.

Using the same vacuum pump for different refrigerants may damage the vacuum pump

or the unit.

Use a clean gauge manifold and charging hose for R410A exclusively.

During the pump-down operation, make sure that the compressor is turned off before

you remove the refrigerant piping.

Do not remove the connection pipe while the compressor is in operation with 2-way or

3-way valve open.

This may cause abnormal pressure in the refrigeration cycle that leads to breakage and

even injury.

CAUTION

This mark indicates procedures which, if improperly performed,

might possibly result in personal harm to the user, or damage

to property.

Read carefully all security information before use or install the air conditioner.

Do not attempt to install the air conditioner or a part of the air conditioner by yourself.

This unit must be installed by qualiﬁ ed personnel with a capacity certiﬁ cate for handling

refrigerant ﬂ uids. Refer to regulation and laws in use on installation place.

The installation must be carried out in compliance with regulations in force in the place

of installation and the installation instructions of the manufacturer.

This unit is part of a set constituting an air conditioner. It must not be installed alone or

with non-authorized by the manufacturer.

Always use a separate power supply line protected by a circuit breaker operating on all

wires with a distance between contact of 3mm for this unit.

The unit must be correctly grounded and the supply line must be equipped with a

differential breaker in order to protect the persons.

The units are not explosion proof and therefore should not be installed in explosive

atmosphere.

This unit contains no user-serviceable parts. Always consult authorized service

personnel to repairs.

When moving, consult authorized service personnel for disconnection and installation

of the unit.

Children should be monitored to ensure they do not play with the device.

This appliance is not intended for use by persons (including children) with reduced

physical, sensory or mental capabilities, or lack of experience and knowledge, unless

they have been given supervision or instruction concerning use of the appliance by a

person responsible for their safety. Children should be supervised to ensure that they

do not play with the appliance.

2. ABOUT THIS PRODUCT

2. 1. Precautions for using R410A refrigerant

WARNING

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

(R22) models, some of the piping and installation and service tools are special. (See

the table below.)

Especially, when replacing a conventional refrigerant (R22) model with a new

refrigerant R410A model, always replace the conventional 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 conventional refrigerant (R22) and for safety.

Therefore, check beforehand. [The charging port thread diameter for R410A is

1/2 UNF 20 threads per inch.]

• Be 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 where

refrigerant composition is stable.

2. 2. 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

(-1 to 53 bar) for high pressure. –0.1 to 3.8 MPa (-1 to 38 bar)

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.

Gas leakage

detector Special gas leakage detector for HFC refrigerant R410A.

Copper pipes

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.

Thicknesses of Annealed Copper Pipes (R410A)

Pipe outside diameter Thickness

6.35 mm (1/4 in.) 0.80 mm

9.52 mm (3/8 in.) 0.80 mm

12.70 mm (1/2 in.) 0.80 mm

15.88 mm (5/8 in.) 1.00 mm

19.05 mm (3/4 in.) 1.20 mm

2. 3. Accessories

WARNING

For installation purposes, be sure to use the parts supplied by the manufacturer or other

prescribed parts. The use of non-prescribed parts can cause serious accidents such as

the unit falling, water leakage, electric shock, or ﬁ re.

Do not throw away the connecting parts until the installation has been complete.
