If the product is installed in disregard of the instructions in thismanual, it will void the manufacturer’s warranty.To avoid getting an electric shock, never touch the electrical componentssoon after the power supply has been turned off. After turning off thepower, always wait 10 minutes or more before you touch the electricalcomponents.Do not turn ON the power until all work has been completed. Turning ONthe power before the work is completed can cause serious accidents suchas electric shock or fire.If refrigerant leaks while work is being carried out, ventilate the area. If therefrigerant comes in contact with a flame, it produces a toxic gas.Installation must be performed in accordance with regulations, codes, orstandards for electrical wiring and equipment in each country, region, orthe installation place.Do not use this equipment with air or any other unspecified refrigerant inthe refrigerant lines.Excess pressure can cause a rupture.During installation, make sure that the refrigerant pipe is attached firmlybefore you run the compressor. Do not operate the compressor under thecondition of refrigerant piping not attached properly with 2-way or 3-wayvalve open. This may cause abnormal pressure in the refrigeration cyclethat leads to rupture and even injury.When installing and relocating the air conditioner, do not mix gases otherthan the specified refrigerant (R410A) to enter the refrigerant cycle.If air or other gas enters the refrigerant cycle, the pressure inside the cyclewill rise to an abnormally high value and cause rupture, injury, etc.To connect the indoor unit and outdoor unit, use air conditioner pipingand cables available locally as standard parts. This manual describes prop-er connections using such installation set.If the supply cord is damaged, it must be replaced by the manufacturer, itsservice agent or similarly qualified persons in order to avoid a hazard.Do not modify power cable, use extension cable or branch wiring. Improp-er use may cause electric shock or fire by poor connection, insufficientinsulation or over current.Do not purge the air with refrigerants but use a vacuum pump to vacuumthe installation.There is not extra refrigerant in the outdoor unit for air purging.Using the same vacuum pump for different refrigerants may damage thevacuum pump or the unit.Use a clean gauge manifold, vacuum pump and charging hose for R410Aexclusively.During the pump-down operation, make sure that the compressor isturned off before you remove the refrigerant piping.Do not remove the connection pipe while the compressor is in operationwith 2 way or 3 way valve open. This may cause abnormal pressure in therefrigeration cycle that leads to rupture and even injury.This appliance is not intended for use by persons (including children) withreduced physical, sensory or mental capabilities, or lack of experienceand knowledge, unless they have been given supervision or instructionconcerning use of the appliance by a person responsible for their safety.Children should be supervised to ensure that they do not play with theappliance.To avoid danger of suffocation, keep the plastic bag or thin film used asthe packaging material away from young children.CAUTIONInstall the product by following local codes and regulations in force at theplace of installation, and the instructions provided by the manufacturer.This product is part of a set constituting an air conditioner. The productmust not be installed alone or be installed with non-authorized device bythe manufacturer.Always use a separate power supply line protected by a circuit breaker oper-ating on all wires with a distance between contact of 3 mm for this product.To protect the persons, earth (ground) the product correctly, and use thepower cable combined with an Earth Leakage Circuit Breaker (ELCB).This product is not explosion proof, and therefore should not be installedin explosive atmosphere.Do not touch the fins of the heat exchanger. Touching the heat exchanger finscould result in damage to the fins or personal injury such as skin rupture.This product contains no user-serviceable parts. Always consult experi-enced service technicians for repairing.When moving or relocating the air conditioner, consult experienced serv-ice technicians for disconnection and reinstallation of the product.Do not place any other electrical products or household belongings underindoor unit or outdoor unit. Dripping condensation from the unit mightget them wet, and may cause damage or malfunction of your property.CAUTIONThe total maximum pipe lengths and height differenceof this product are shown in the table.If the units are further apart than this, correct opera-tion cannot be guaranteed.CUSTOMER GUIDANCEExplain the following to the customer in accordance with the oper-ating manual:(1) Starting and stopping method, operation switching, temperatureadjustment, timer, air flow switching, and other remote control-ler operations.(2) Air filter removal and cleaning, and how to use the air louvers.(3) Give the operating and installation manuals to the customer.Pipe length Maximum height(between indoor and outdoor)MAX. MIN.50 m 5 m 30 mWARNINGThe basic installation work procedures are the same as conventional refrig-erant (R22) models.However, pay careful attention to the following points:Since the working pressure is 1.6 times higher than that of conventional re-frigerant (R22) models, some of the piping and installation and service toolsare special. (See the table below.)Especially, when replacing a conventional refrigerant (R22) model with anew refrigerant R410A model, always replace the conventional piping andflare nuts with the R410A piping and flare nuts.Models that use refrigerant R410A have a different charging port threaddiameter to prevent erroneous charging with conventional refrigerant (R22)and for safety. Therefore, check beforehand. [The charging port thread diam-eter for R410A is 1/2-20 UNF.]Be more careful that foreign matter (oil, water, etc.) does not enter the pip-ing than with refrigerant (R22) models. Also, when storing the piping, se-curely seal the opening by pinching, taping, etc.When charging the refrigerant, take into account the slight change in thecomposition of the gas and liquid phases. And always charge from the liquidphase where refrigerant composition is stable.SPECIAL TOOLS FOR R410ATool name Contents of changeGauge manifoldPressure is high and cannot be measured with a conven-tional (R22) gauge. To prevent erroneous mixing of otherrefrigerants, 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 materialand base size were changed.Vacuum pump A conventional vacuum pump can be used byinstalling a vacuum pump adapter.Gas leakage detector Special gas leakage detector for HFC refrigerant R410A.Copper pipesIt is necessary to use seamless copper pipes and it is desirable that the amount ofresidual 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 value or capillary tube may become blocked with contaminants.As an air conditioner using R410A incurs pressure higher than when usingR22, it is necessary to choose adequate materials.Thicknesses of copper pipes used with R410A are as shown in Table1. Neveruse copper pipes thinner than 0.8 mm even when it is available on the market.CONNECTION PIPE REQUIREMENTNominaldiameter Outerdiameter Thickness Outerdiameter Outerdiameter3/8 in 9.52 mm 0.8 mm 165 ft (50 m) 99 ft (30 m)5/8 in 15.88 mm 1.0 mmCAUTIONRead carefully all safety information written in this manual before you in-stall or use the air conditioner.This unit must be installed by qualified personnel with a capacity certifi-cate for handling refrigerant fluids. Refer to regulation and laws in use oninstallation place.WARNINGTo install a unit that uses R410A refrigerant, use dedicated tools and pipingmaterials that have been manufactured specifically for R410A use. Becausethe pressure of R410A refrigerant is approximately 1.6 times higher thanR22, failure to use dedicated piping material or improper installation cancause rupture or injury. Furthermore, it can cause serious accidents such aswater leakage, electric shock, or fire.9374995431_IM_EN.indd 1 14/12/2558 13:50:02
