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.

CAUTION

This mark indicates procedures which, if improperly performed, might possibly result in personal harm to the user, or damage to property.

WARNING

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

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

VSHFL¿HGUHIULJHUDQW5$WRHQWHUWKHUHIULJHUDQWF\FOH

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.

WARNING

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.

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

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.

3. INSTALLATION WORK

Please obtain the approval of the customer when selecting the location of installation and installing the unit.

3. 1. Selecting an installation location

WARNING

Securely install the outdoor unit at a location that can withstand the weight of the unit.

Otherwise, the outdoor unit may fall and cause injury.

Be sure to install the outdoor unit as prescribed, so that it can withstand earthquakes and typhoons or other strong winds. Improper installation can cause the unit to topple or fall, or other accidents.

Do not install the outdoor unit near the edge of a balcony. Otherwise, children may climb onto the outdoor unit and fall off of the balcony.

CAUTION

Do not install the outdoor 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.

‡ $UHD¿OOHGZLWKPLQHUDORLORUFRQWDLQLQJDODUJHDPRXQWRIVSODVKHGRLORUVWHDP such as a kitchen. It will deteriorate plastic parts, causing 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 refrigerant leakage.

‡ Area containing equipment that generates electromagnetic interference. It will cause the control system to malfunction, preventing the unit from operating normally.

‡ Area where animals may urinate on the unit or ammonia may be generated.

Please install the outdoor unit without slant.

Install the outdoor unit in a well-ventilated location away from rain or direct sunlight.

If the outdoor unit must be installed in an area within easy reach of the general public, install as necessary a protective fence or the like to prevent their access.

Install the outdoor unit in a location that would not inconvenience your neighbors, as

WKH\FRXOGEHDIIHFWHGE\WKHDLUÀRZFRPLQJRXWIURPWKHRXWOHWQRLVHRUYLEUDWLRQ,ILW must be installed in proximity to your neighbors, be sure to obtain their approval.

If the outdoor unit is installed in a cold region that is affected by snow accumulation, snow fall, or freezing, take appropriate measures to protect it from those elements. To ensure a stable operation, install inlet and outlet ducts.

Install the outdoor unit in a location that is away from exhaust or the vent ports that discharge vapor, soot, dust, or debris.

CAUTION

A damaged insulation can cause a short circuit.

Never install a power factor improvement condenser. Instead of improving the power factor, the condenser may overheat.

Before servicing the unit, turn the power supply switch OFF. Then, do not touch electric parts for 5 minutes due to the risk of electric shock.

CAUTION

The primary power supply capacity is for the air conditioner itself, and does not include the concurrent use of other devices.

Do not use crossover power supply wiring for the outdoor unit.

If the electrical power is inadequate, contact your electric power company.

Install a breaker in a location that is not exposed to high temperatures.

If the temperature surrounding the breaker is too high, the amperage at which the breaker cuts out may decrease.

This system uses an inverter which means that it must be used an earth leakage breaker that can handle harmonics in order to prevent malfunctioning of the earth leakage breaker itself.

When the electrical switchboard is installed outdoors, place it under lock and key so that it is not easily accessible.

Do not fasten the power supply cable and connection cable together.

Always keep to the maximum length of the connection cable. Exceeding the maximum length may lead to erroneous operation.

The static electricity that is charged to the human body can damage the control PC

How to connect wiring to the terminal

Caution when wiring cable

Use crimp-type terminals with insulating slee Y es as shown in the ¿ gure to connect to the terminal block.

Securely clamp the crimp-type terminals to the wires using an appropriate tool so that the wires do not come loose.

Use the speci ¿ ed wires, connect them securely, and fasten them so that there is no stress placed on the terminals.

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.

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

See the table below for the terminal screw tightening torques.
