4 3 1 Precautions for Safety The manufacturer shall not assume any liability for the damage caused by not observing the description of this manual. WRNING General Carefully read Owner s Manual before starting the air conditioner. There are many important things to keep in mind for daily operation. sk for installation to be performed by the dealer or a professional. Only a qualified installer is able to install an air conditioner. If a non-qualified person installs an air conditioner, it may result in problems such as fire, electric shock, injury, water leakage, noise and vibration. Do not use any refrigerant different from the one specified for complement or replacement. Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may result in a failure or explosion of the product or an injury to your body. Before opening the service panel of the outdoor, set the circuit breaker to the OFF position. Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with the interior parts. Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit breakers for both the indoor and outdoor s to the OFF position. Otherwise, electric shock may result. Wear protective gloves and safety work clothing during installation, servicing and removal. Do not touch the aluminium fin of the outdoor. You may injure yourself if you do so. If the fin must be touched for some reason, first put on protective gloves and safety work clothing, and then proceed. Do not climb onto or place objects on top of the outdoor. You may fall or the objects may fall off of the outdoor and result in injury. Before cleaning the filter or other parts of the outdoor, set the circuit breaker to OFF without fail, and place a Work in progress sign near the circuit breaker before proceeding with the work. The refrigerant used by this air conditioner is the R410. The air conditioner must be transported in stable condition. If any part of the product are broken, contact your distributor. Selection of installation location Do not install in a location where flammable gas leaks are possible. If the gas should leak and accumulate around the, it may ignite and cause a fire. During transporting the air conditioner, wear shoes with protective toe caps, protective gloves, and other protective clothing. To transport the air conditioner, do not take hold of the bands around the packing carton. You may injure yourself if the bands should break. Places where the operation sound of the outdoor may cause a disturbance. (Especially at the boundary line with a neighbour, install the air conditioner while considering the noise.) Installation The designated bolts (M1) and nuts (M1) for securing the outdoor must be used when installing the. Install the outdoor property in a location that is durable enough to support the weight of the outdoor. Insufficient durability may cause the outdoor to fall, which may result in injury. Install the in the prescribed manner for protection against strong wind and earthquake. Incorrect installation may result in the falling down, or other accidents. Fix the screws back which have been removed for installation or other purposes. Refrigerant piping Install the refrigerant securely during the installation work before operating the air conditioner. If the compressor is operated with the valve open and without refrigerant, the compressor sucks air and the refrigeration cycles is over pressurized, which may cause a injury. Tighten the flare nut with a torque wrench in the specified manner. Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may result in refrigerant leakage. Ventilate the air if the refrigerant gas leaks during installation. If the leaked refrigerant gas comes into contact with fire, toxic gas may be produced. When the air conditioner has been installed or relocated, follow the instructions in the Installation Manual and purge the air completely so that no gases other than the refrigerant will be mixed in the refrigerating cycle. Failure to purge the air completely may cause the air conditioner to malfunction. Nitrogen gas must be used for the airtight test. Electrical wiring Only a certified installer or qualified service person(*1) is allowed to carry out the electrical work of the air conditioner. When connecting the electrical wires, repairing the electrical parts or undertaking other electrical jobs, wear gloves to provide protection for electricians and from heat, insulating shoes and clothing to provide protection from electric shocks. Failure to wear this protective gear may result in electric shocks. When executing address setting, test run, or troubleshooting through the checking window on the electric parts box, put on insulated heat-proof gloves, insulated shoes and other clothing to provide protection from electric shock. Otherwise you may receive an electric shock. Use wiring that meets the specifications in the Installation Manual, NEC and the local codes. Check that the product is properly earthed. (Grounded) Do not connect the ground line to a gas, water, lightning conductor, or a telephone earth line. fter completing the repair or relocation work, check that the ground wires are connected properly. Install a circuit breaker that meets the specifications in the installation manual, NEC and local codes. Under no circumstances must the power cable be extended. Connection trouble in the places where the cable is extended may give rise to smoking and/or a fire. Do not supply power from the power terminal block equipped on the outdoor to another outdoor. Capacity overflow may occur on the terminal block and may result in fire. Each outdoor should have its own power supply. Test run Before operating the air conditioner after having completed the work, check that the electrical parts box cover of the indoor and service panel of the outdoor are closed, and set the circuit breaker to the ON position. You may receive an electric shock if the power is turned on without first conducting these checks. If there is any kind of trouble (such as when an error display has appeared, there is a smell of burning, abnormal sounds are heard, the air conditioner fails to cool or heat or water is leaking) has occurred in the air conditioner, do not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact a qualified service person. Take steps to ensure that the power will not be turned on (by marking out of service near the circuit breaker, for instance) until qualified service person arrives. Continuing to use the air conditioner in the trouble status may cause mechanical problems to escalate or result in electric shocks or other failure. Upon completion of the installation work, check for refrigerant leaks and check the insulation resistance and water drainage. Then conduct a test run to check that the air conditioner is operating properly. Explanations given to user Upon completion of the installation work, tell the user where the circuit breaker is located. If the user does not know where the circuit breaker is, he or she will not be able to turn it off in the event that trouble has occurred in the air conditioner. If the fan grille is damaged, do not approach the outdoor but set the circuit breaker to the OFF position, and contact a qualified service person(*1) to have the repairs done. Do not set the circuit breaker to the ON position until the repairs are completed. fter the installation work, follow the Owner s Manual to explain to the customer how to use and maintain the. Relocation Only a certified installer(*1) or service person is allowed to relocate the air conditioner. When the pump-down work is carried out shut down the compressor before disconnecting the refrigerant. Disconnecting the refrigerant with the service valve left open and the compressor still operating will cause air or other gas to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in rupture, injury or other trouble. Do not recover the refrigerant into the outdoor. Use a refrigerant recovery machine to recover the refrigerant after moving or repairing. It is impossible to recover the refrigerant into the outdoor. Refrigerant recovery into the outdoor may result in serious accidents such as explosion of the, injury or other accidents.

5 CUTION New Refrigerant ir Conditioner Installation THIS IR CONDITIONER USES THE ENVIRONMENTRY FRIENDRY HFC REFRIGERNT (R410) WHICH DOES NOT DESTROY OZONE LYER. The characteristics of R410 refrigerant are; easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1.6 times higher than that of refrigerant R. ccompanied with the new refrigerant, refrigerating oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle. To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the main and installation tools are changed from those for the conventional refrigerant. For connecting s, use new and clean piping designed for R410, and please care so that water or dust does not enter. ccessory Parts Part name MP07, MP096 type Q ty MP114 type Shape Usage Owner s Manual 1 1 (Be sure to hand it to the customers.)
