(The stop valves are fully closed when shipped.) Leave closed. 2) Connect gauge manifold to ports of stop valves. Stop valve cap Compound pressure gauge Valve stem (inside) (Torque 15 to -14.7 psi [Gauge] (for R410A) 22 ft-lb, 19.6 to (-0.101 Mpa) pressure gauge Close 29.4 N•m, 200 (for R410A) Open to 300 kgf•cm) Stop valve for LIQUID Gauge manifold valve Handle (for R410A) \ Low Handle High Hexagonal wrench Stop valve for Charge hose GAS (for R410A) Service port cap (Torque 10 to 13 ft Adapter for lb, 13.7 to 17.7 N•m, preventing the 140 to 180 kgf•cm) back flow Vacuum pump (or the vacuum pump with the function to prevent the back flow) Precautions when using the control valve When attaching the control valve to the service port, valve core may deform or loosen if excess pressure is applied. This may cause gas leak. �i�O�S'rvice port A Control valve Open Close Charge hose Body When attaching the control valve to the service port, make sure that the valve core is in closed position, and then tighten part A. Do not tighten part A or turn the body when valve core is in open position. 3) Evacuate the system to 4000 microns from both service valves. System manifold gauges must not be used to measure vacuum. A micron gauge must be used at all times. Break the vacuum with Nitrogen(N2) into the discharge service valve to 0 PSIG. 4) Evacuate the system to 1500 microns. Break the vacuum with Nitrogen(N2) into the discharge service valve to 0 PSIG. 5) Evacuate the system to 500 microns. 6) Close gauge manifold valves, stop the pump, and conduct a 30 minute rise test. 7) System should hold 500 microns for a minimum of 1 hour. 8) Fully open the valve stem of all stop valves on both sides of gas pipe and liquid pipe by the hexagonal wrench. If the valve stem hits the stopper, do not turn it any further. Operating without fully opening lowers the performance and this causes trouble. 9) Refer to 1-3 and charge the prescribed amount of additional refrigerant if needed. Be sure to charge slowly with liquid refrigerant. Otherwise composition of the refrigerant in the system may be changed and affect performance of the air conditioner. 10) Remove gauge manifolds and replace service port caps and tighten. 11) Leak test 5.

THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY Be sure to read "THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY" before installing the air conditioner Be sure to observe the warnings and cautions specified here as they include important items related to safety. After reading this manual, be sure to keep it together with the OPERATING INSTRUCTIONS for future reference. ■ Do not install the unit by yourself (user). Incomplete installation could cause fire or electric shock, injury due to the unit falling, or leakage of water. Consult the dealer from whom you purchased the unit or a qualified installer. ■ Perform the installation securely referring to the installation manual. Incomplete installation could cause fire or electric shock, injury due to the unit falling, or leakage of water. ■ When installing the unit, use appropriate protective equipment and tools for safety. Failure to do so could cause injury. ■ Install the unit securely in a place which can bear the weight of the unit. If the installation location cannot bear the weight of the unit, the unit could fall causing injury. ■ Perform electrical work according to the installation manual and be sure to use an exclusive circuit. Do not connect other electrical appliances to the circuit. If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock. ■ Do not damage the wires by applying excessive pressure with parts or screws. Damaged wires could cause fire. ■ Be sure to cut off the main power in case of setting up the indoor P.C. board or wiring works. Failure to do so could cause electric shock. ■ Use the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal block connecting sections so the stress of the wires is not applied to the sections. Incomplete connecting and securing could cause fire. ■ Do not install the unit in a place where inflammable gas may leak. If gas leaks and accumulates in the area around the unit, it could cause an explosion. ■ Do not use intermediate connection of the power cord or the extension cord and do not connect many devices to one AC outlet. It could cause a fire or an electric shock due to defective contact, defective insulation, exceeding the permissible current, etc. ■ Be sure to use the parts provided or specified parts for the installation work. The use of defective parts could cause an injury or leakage of water due to a fire, an electric shock, the unit falling, etc. ■ When plugging the power supply plug into the outlet, make sure that there is no dust, clogging, or loose parts in both the outlet and the plug. Make sure that the power supply plug is pushed completely into the outlet. If there is dust, clogging, or loose parts on the power supply plug or the outlet, it could cause electric shock or fire. If loose parts are found on the power supply plug, replace it. ■ Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely. ■ Perform the drainage/piping work securely according to the installation manual. If there is defect in the drainage/piping work, water could drop from the unit, soaking and damaging household goods. ■ Do not touch the air inlet or the aluminum fins of the outdoor unit. This could cause injury. 1-2. SPECIFICATIONS If the electrical cover of the indoor unit and/or the service panel of the outdoor unit are not attached securely, it could result in a fire or an electric shock due to dust, water, etc. ■ When installing, relocating, or servicing the unit, make sure that no sub- stance other than the specified refrigerant (R410A) enters the refrigerant circuit. Any presence of foreign substance such as air can cause abnormal pressure rise and may result in explosion or injury. The use of any refrigerant other than that specified for the system will cause mechanical failure, system malfunction, or unit breakdown. In the worst case, this could lead to a serious impediment to securing product safety. ■ Do not discharge the refrigerant into the atmosphere. If refrigerant leaks during installation, ventilate the room. If refrigerant comes in contact with a fire, harmful gas could be generated. Refriger- ant leakage may cause suffocation. Ventilate the room. ■ Check that the refrigerant gas does not leak after installation has been completed. If refrigerant gas leaks indoors, and comes into contact with the flame of a fan heater, space heater, stove, etc., harmful substances will be generated. ■ Use appropriate tools and piping materials for installation. The pressure of R410A is 1.6 times more than R22. Not using appropriate tools or materials and incomplete installation could cause the pipes to burst or injury. ■ When pumping down the refrigerant, stop the compressor before discon- necting the refrigerant pipes. If the refrigerant pipes are disconnected while the compressor is running and the stop valve is open, air could be drawn in and the pressure in the refrigera- tion cycle could become abnormally high. This could cause the pipes to burst or injury. ■ When installing the unit, securely connect the refrigerant pipes before starting the compressor. If the compressor is started before the refrigerant pipes are connected and when the stop valve is open, air could be drawn in and the pressure in the refrigeration cycle could become abnormally high. This could cause the pipes to burst or injury. ■ Fasten a flare nut with a torque wrench as specified in this manual. If fastened too tight, a flare nut may break after a long period and cause refrigerant leakage. ■ The unit shall be installed in accordance with national wiring regulations. ■ Ground the unit correctly. Do not connect the ground to a gas pipe, water pipe, lightning rod or telephone ground. Defective grounding could cause electric shock. ■ Be sure to install a Ground Fault Interrupt (GFI) circuit breaker. Failure to install a Ground Fault Interrupt (GFI) circuit breaker may result in electric shock or fire. Do not install the outdoor unit where small animals may live. If small animals enter and touch the electric parts inside the unit, it could cause a malfunction, smoke emission, or fire. Also, advise user to keep the area around the unit clean.

See the installation manual coming with the indoor unit, and make sure all the units operate properly. • If the test run with all the units is performed at once, possible erroneous connections of the refrigerant pipes and the indoor/outdoor unit connecting wires cannot be detected. Thus, be sure to perform the test run one by one. About the restart protective mechanism Once the compressor stops, the restart preventive device operates so the compressor will not operate for 3 minutes to protect the air conditioner. Wiring/piping correction function This unit has a wiring/piping correction function which corrects wiring and piping combination. When there is possibility of incorrect wiring and piping combination, and confirming the combination is difficult, use this function to detect and correct the combination by following the procedures below. Make sure that the following is done. • Power is supplied to the unit. • Stop valves are open. Note: During detection, the operation of the indoor unit is controlled by the outdoor unit. During detection, the indoor unit automatically stops operation. This is not a mal- function. Procedure Press the piping/wiring correction switch (SW871) 1 minute or more after turning on the power supply. • Correction completes in 10 to 20 minutes. When the correction is completed, its result is shown by LED indication. Details are described in the following table. • To cancel this function during its operation, press the piping/wiring correction switch (SW871) again. • When the correction completed without error, do not press the piping/wiring correction switch (SW871) again. When the result is "Not completed", press the piping/wiring correction switch (SW871) again to cancel this function. Then, confirm the wiring and piping combination in a conventional manner by operating the indoor units one by one. The operation is done while the power is supplied. Make sure not to contact parts other than the switch, including the P.C. board. This may cause electric shock or burn by hot parts and live parts around the switch. Contacting the live parts may cause P.C. board damage. To prevent electronic control P.C. board damage, make sure to perform static elimination before operating this function. • This function does not operate when the outside temperature is 32°F (0°C) or below. ) LED indication during detection: LED1 (Red) LED2 (Yellow) LED3 (Green) Lighted Lighted Once Result of piping/wiring correction function LED1 I LED2 LED3 Result (Red) (Yellow) (Green) Completed Lighted Not lighted Lighted (Problem corrected or normal) Once Once Once Not completed (Detection failed) Refer to "SAFETY PRE- CAUTIONS WHEN CAUTIONS WHEN LED BLINKS' located behind the service panel. 4-6. EXPLANATION TO THE USER • Using the OPERATING INSTRUCTIONS, explain to the user how to use the air conditioner (how to use the remote controller, how to remove the air filters, how to remove or put the remote controller in the remote controller holder, how to clean, precautions for operation, etc.). • Recommend the user to read the OPERATING INSTRUCTIONS carefully. 5. PUMPING DOWN When relocating or disposing of the air conditioner, pump down the system following the procedure below so that no refrigerant is released into the atmosphere. 1) Turn off the breaker. 2) Connect the gauge manifold valve to the service port of the stop valve on the gas pipe side of the outdoor unit. 3) Fully close the stop valve on the liquid pipe side of the outdoor unit. 4) Turn on the breaker. 5) Start the emergency COOL operation on all the indoor units. 6) When the pressure gauge shows 0.1 to 0 psi [Gauge] (0.05 to 0 MPa), fully close the stop valve on the gas pipe side of the outdoor unit and stop the operation. (Refer to the indoor unit installation manual about the method for stopping the operation.) If too much refrigerant has been added to the air conditioner system, the pressure may not drop to 0.1 to 0 psi [Gauge] (0.05 to 0 MPa), or the protection function may operate due to the pressure increase in the high-pressure refrigerant circuit. If this occurs, use a refrigerant collecting device to collect all of the refrigerant in the system, and then recharge the system with the correct amount of refrigerant after the indoor and outdoor units have been relocated. 7) Turn off the breaker. Remove the pressure gauge and the refrigerant piping. t WARNING When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes. The compressor may burst and cause injury if any foreign substance, such as air, enters the pipes. En-7 Outils necessaires A ('installation Tournevis Phillips Cle hexagonale de 5/32 po.

ESPECIFICACIONES ■ Al instalar, reubicar o reparar la unidad, aseg6rese de que an el circuito de refrigeraci6n no entra ninguna otra sustancia que no sea el refrigerante espe- cificado (11410A). La presencia de cualquier otra sustancia extrafia, como aire por ejemplo, puede provocar una elevaci6n an6mala de la presi6n, una explosi6n o danos corporales. El use de un refrigerante distinto al especificado por el sistema ocasionar6 fallos mec6nicos, malfuncionamiento del sistema o averias en Is unidad. En el peor de los casos, esto podria Ilegar a ser un serio impedimento pare garantizar el use seguro del producto. ■ No descargue el refrigerante an el ambiente. Si se producen fugas de refrige- rante durante la instalaci6n, ventile la habitaci6n. Si el refrigerante entra an contacto con una llama, podria generarse gas nocivo. La perdida de refrigerante puede provocar asfixia. Ventile la habitaci6n. ■ Una vez acabada la instalaci6n, compruebe que no haya fugas de gas refrige- rante. Si se produjeran perdidas de gas refrigerante an un interior y entraran an contacto con la llama de un calefactor con ventilador, un calentador, una estufa, etc. se generarian sustancias nocivas. ■ Utilice las herramientas apropiadas y los materiales de conducci6n adecuados Para la instalaci6n. La presi6n del refrigerante R410A es 1,6 veces mayor que la del R22. Si no se utilizan herramientas o materiales apropiados, o si se realize una instalaci6n defectuosa, las tuberias podrian estallar o sufrir danos. ■ Al bombear el refrigerante, detenga el compresor antes de desconectar las tuberias de refrigerante. Si las tuberias de refrigerante se desconectan con el compresor en marcha y la v6lvula de retenci6n est6 abierta, podria entrar aire y Is presi6n del ciclo de refrige- raci6n aumentaria de forma an6mala. Esto podria hacer que las tuberias estallaran o sufrieran danos. ■ Al instalar Is unidad, conecte las tuberias de refrigerante de forma flja antes de poner an marcha el compresor. Si el compresor se pone an marcha antes de que las tuberias de refrigerante esten conectadas y la v6lvula de retenci6n se abra, podria entrar aire y la presi6n del ciclo de refrigeraci6n aumentaria de forma an6mala. Esto podria hacer que las tuberias estallaran o sufrieran danos. ■ Apriete la tuerca abocardada con una Have dinamometrica tal y como se as- pecifica en el presente manual. Si la aprieta demasiado, la tuerca abocardada podria romperse transcurrido un tiempo, causando perdidas de refrigerante. ■ Instale la unidad de acuerdo con la normativa Para instalaciones electricas. ■ Conecte a tierra la unidad. No conecte el cable de tierra a una tuberia de gas, de ague o al cable de tierra de un tel6fono. Una conexi6n defectuosa podria provocar una descarga el6ctrica. ■ Asegurese de instalar un disyuntor del Interruptor de fallo de conexi6n a tierra (GFI).
