1 SAFETY PRECAUTIONS

• Ensure that all Local, National and International regulations are satisfied.

• Read this “SAFETY PRECAUTIONS” carefully before Installation.

• The precautions described below include the important items regarding safety. Observe them without fail.

• After the installation work, perform a trial operation to check for any problem. Follow the Owner’s Manual to explain how to use and
maintain the unit to the customer.

• Turn off the main power supply switch (or breaker) before the unit maintenance.

• Ask the customer to keep the Installation Manual together with the Owner’s Manual.

CAUTION

New Refrigerant Air Conditioner Installation

• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE
LAYER.

R410A refrigerant is apt to be affected by impurities such as water, o xidizing membrane, and oils because the working pressure of
R410A refrigerant is approx. 1.6 times as that of refrigerant R22. Accompanied with the adoption of the new refrigerant, the
refrigeration machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant,
or refrigeration machine oil does not enter the new type refrigerant R410A air conditioner circuit.
To prevent mixing of refrigerant or refrigera ting machine oil, the sizes of connecting sections of charging port on main unit and
installation tools are different from those of the conventional refrigerant units. Accordingly, special tools are required for the new
refrigerant (R410A) units as shown on page 23. For connecting pipes, use new and clean piping materials with high pressure
fittings made for R410A only, so that water and/or dust does not enter. Moreover, do not use the existing piping because there are
some problems with pressure fittings and possible impurities in existing piping.

CAUTION

TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SU PPLY

Disconnection from the supply mains:
The means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.

ENGLISHFRANÇAISDEUTSCHITALIANOESPAÑOLΕΛΛΗΝΙΚΗPORTUGUÊS###SW######RU###

WARNING

• Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.

Inappropriate installation may result in water leakage, electric shock or fire.

• Turn off the main power supply switch or breaker before attempting any electrical work.

Make sure all power switches are off. Failure to do so may cause an electric shock.

• Connect all of the installation wiring correctly.

If the installation wiring is incorrect, electrical parts may be damaged.

• When moving the air-con ditioner for installation to another place, be very careful not to allow the specified refrigerant

(R410A) to become mixed with any other gaseous body into the refrigeration circuit. If air or any other gas mixes with the
refrigerant, the gas pressure in the refrigeration circuit will become abnormally high and it may result in the pipe bursting or
personnel injuries.

• Do not modify this unit by removing any of the safety guards or by overriding any of the safety interlock switches.

• Exposure of the unit to water or other forms of moisture before installation may cause a short circuit of the electrical parts.

Do not store it in a wet basement or expose to rain or water.

• The electrical work should be performed by a qualified electrician in accordance with the tech nical standards for electrical

equipment, internal wiring regulations, and installation manual for the electrical equipment. A dedicated circuit should be
used, and the voltage should match the rated voltage of the product. If the power supply circuit does not have enough
capacity or the work is performed improperly, an electric shock or fire can result.

• Be sure to connect the indoor and outdoor unit wires at their tips. Do not connect the wires below the tips. If the connections

and fixtures are not made properly, overheating or a fire can result.

• Connect the wiring between the indoor and outdoor units so that the cord clamp does not stick out, and attach the covers

properly. If the clamp is not attached properly, the terminal sections can overheat, and a fire or electric shock can result.

• Always use the supplied parts or specified parts for the installation work parts. Usage of different parts can cause the unit to

fall, a water leak, fire, or electric shock.

• After unpacking the unit, examine for po ssible damage.

• Do not install in a place that might increase the vibration of the unit.

• To avoid personal injury (with sharp edges), be careful when handling parts.

• Perform installation work properly according to the Installation Manual.

Incorrect installation may result in water leakage, electric shock or a fire.

1 EN

• When the air conditioner is installed in a small room, provide appropriate measures to ensure that in the event of a refrigerant

leak the rooms does not exceed the critical level.

• Install the air conditioner securely in a location where the base can sustain the weight of the unit adequately.

• Perform the specified installation work to guard against an earthquake.

If the air conditioner is not installed appropriately, accidents may occur due to the unit falling.

• If refrigerant gas has leaked during the installation work, ventilate the room immediately.

If the leaked refrigerant gas comes in contact with fire, noxious gases may be generated.

• After the installation work, confirm that refrigerant gas does not leak.

If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gases maybe generated.

• Use only the specified wiring during the unit installation. Ensure that all terminals are securely fixed, so preventing any

external forces having a negative effect on the terminals .

• Be sure to provide grounding.

Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.

• Do not install the air conditioner in a location that maybe subjected to a risk of exposure to a combustible gas.

If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.

• Do not install in locations where the unit will get splashed by water or with high humidity such as bathrooms. This can cause

deterioration of the insulation, resulting in an electric shock or fire.

• Check the following points before starting operation in the installation work.

- The pipes are securely connected and do not leak.

- The service valve is opened.
Operating the compressor while the service valve is closed will result in an abnormally high pressure, and can possibly
damage the compressor and other parts. Also, any leaks in the connections can cause air to be sucked in, resulting in an
even higher abnormally pressure, and can cause a pipe rupture or injury.

• When carrying out the pump-down work, shut down the compressor before disconnecting the refrigerant pipe. Disconnecting

the refrigerant pipe with the service valve left open and with the compressor still operating will cause air, etc. to be sucked in,
raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in rupturing, injury, etc.

CAUTION

• Wear work gloves when carrying out the installation work or repairs. Contact with parts, etc. may cause injury if the work or

repairs are conducted without wearing gloves.

• Earth leakage breakers are required in certain installation locations. Failure to install the earth leakage breakers can result in

an electric shock.

• The pipes for the drain work should be installed properly in accordance with the installation manual to ensure proper

draining. Failure to install the pipes properly can cause a leak indoors and wet the furniture and other objects in the home.

• Tighten the flare nut with a torque wrench using the specified method. If the flare nut is over-tightened, it can crack over a

long period of time, resulting in a refrigerant leak.

• Do not touch the inlets or aluminum fins of the indoor and outdoor unit. An injury could result.

• Do not install the outdoor unit where small animals typically live. If small animals get inside the unit and touch the electrical

parts, a failure or fire can result. Also, please keep the area around the outdoor unit clear of fallen leaves and other objects.

• After the installation w ork i s completed, perform test operation to check that there is nothing abnormal, and explain to the

customer the operating and cleaning procedures based on the owner's manual. Also, ask the customer to store this
installation manual together with the owner's manual.

6 REFRIGERANT PIPING AND EVACUATING

Refrigerant piping

1. If the outdoor units a re to be moun ted on a w a ll, make sure that the suppo rting platform is sufficiently strong. Th e plat form should

be designed and manufactured to maintain its strength over a long period of time, and sufficient consideration should be given to
ensuring that the outdoor unit will not fall.

2. Use copper pipe with 0.8 mm or more thickness.

3. Flare nut and flare works are different from those of the conventional refrigerant.

Take out the flare nut attached to the main unit of the air conditioner, and use it.

CAUTION

IMPORTANT 4 POINTS FOR PIPING WORK

1. Remove dust and moisture from the inside of the connecting pipes.
