ABOUT THE UNIT2.1. Precautions for using the R410ArefrigerantWARNING• Do not introduce any substance other than the prescribed refrigerant into the refrigeration cycle.If air enters the refrigeration cycle, the pressure in the refrigeration cycle will become abnormally high and cause the piping to rupture.• If there is a refrigerant leakage, make sure that it does not exceed the concentration limit.If a refrigerant leakage exceeds the concentration limit, it can lead to accidents such as oxygen starvation.• Do not touch refrigerant that has leaked from the refrigerant pipe connections or other area. Touching the refrigerant directly can cause frostbite.• If a refrigerant leakage occurs during operation, immediately vacate the premises and thoroughly ventilate the area.If the refrigerant comes in contact with a flame, it produces a toxic gas.2.2. Special tool for R410AWARNING• To install a unit that uses the R410A refrigerant, use dedicated tools and piping materials that have been manufactured specifi cally for R410A use.Because the pressure of the R410A refrigerant is approximately 1.6 times higher than the R22, failure to use dedicated piping material or improper installation can cause rupture or injury.Furthermore, it can cause serious accidents such as water leakage, electric shock, or fi re.Tool name Contents of changeGauge manifold• Pressure is huge and cannot bemeasured with a conventional gauge.To prevent erroneous mixing of otherrefrigerants, the diameter of each porthas been changed.It is recommended to use a gaugemanifold with a high pressure displayrange –0.1 to 5.3 MPa and a lowpressure display range –0.1 to 3.8 MPa. Charging hose• To increase pressure resistance, thehose material and base size werechanged.Vacuum pump• A conventional vacuum pump can beused by installing a vacuum pumpadapter.Gas leakagedetector• Special gas leakage detector for HFCrefrigerant R410A.2.3. AccessoriesWARNING• For installation purposes, be sure to use the parts supplied by the manufacturer or other prescribed parts.The use of non-prescribed parts can cause serious accidents such as the unit to fall, water leakage, electric shock, or fi re.• The following installation parts are furnished. Use them as required.• Keep the Installation Manual in a safe place and do not discard any other accessories until the installation work has been completed.En-2Binder (Medium)Coupler heat insulation (Small)Coupler heat insulation (Large)Special nut A(Large flange)Special nut B(Small flange)HangerHose bandDrain hose insulationEn-4CAUTION• Do not use the unit for special purposes, such as storing food, raising animals, growing plants, or preserving precision devices or art objects.It can degrade the quality of the preserved or stored objects.• Do not install where there is the danger of combustible gas leakage.• Do not install the unit near a source of heat, steam, or fl ammable gas.• Install the unit where drainage does not cause any trouble.• Install the indoor unit, outdoor unit, power supply cable, transmission cable, and remote control cable at least 1 m away from a television or radio receivers. The purpose of this is to prevent TV reception interference or radio noise.(Even if they are installed more than 1 m apart, you could still receive noise under some signal conditions.)• If children under 10 years old may approach the unit, take preventive measures so that they cannot reach the unit.• Decide the mounting position with the customer as follows:(1) Install the indoor unit on a place having a suf fi cient strength so that it withstands against the weight of the indoor unit.(2) The inlet and outlet ports should not be obstructed; the air should be able to blow all over the room.(3) Leave the space required to service the air conditioner.(4) A place from where the air can be distributed evenly throughout the room by the unit.(5) Install the unit where connection to the outdoor unit is easy.(6) Install the unit where the connection pipe can be easily installed.(7) Install the unit where the drain pipe can be easily installed.(8) Install the unit where noise and vibrations are not ampli fi ed.(9) Take servicing, etc., into consideration and leave the spaces. Also install the unit where the fi lter can be removed.(10) Providing as much space as possible between the indoorunit and the ceiling will make work much easier.(11) If installing in a place where its humidity exceeds 80%, useheat insulation to prevent condensation.3.2. Installation dimensions• Provide the space around the unit as shown in the following fi gure.400 mm or more 150 mm or more ❈1❈1 400mm or more when drain from drain pipe.• Provide a service hole for inspection purposes.• Do not place any wiring or illumination in the service space, as they will impede service.• When an air fi lter is installed on the air inlet, provide enough service space to replace the fi lter.AirAirService holeControl box300 mmor more 500 mm or more500 m m o r m o r e100 m mAir AirService spaceControl box300 mm or more1,550 mm or more500 m m o r m o r e100 m mIntake panel3.3. Installing the unitWARNING• Install the air conditioner in a location which can withstand a load do at least fi ve times the weight of the main unit and which will not amplify sound or vibration.

Also, when storing the piping, securely seal the openings by pinching, taping, etc.• While welding the pipes, be sure to blow dry nitrogen gas through them.4.1. Selecting the pipe materialCAUTION• Do not use existing pipes.• Use pipes that have clean external and internal sides without any contamination which may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or water.• It is necessary to use seamless copper pipes.Material : Phosphor deoxidized seamless copper pipesIt is desirable that the amount of residual oil is less than 40 mg/10 m.• Do not use copper pipes that have a collapsed, deformed, or discolored portion (especially on the interior surface). Otherwise, the expansion valve or capillary tube may become blocked with contaminants.• Improper pipe selection will degrade performance. As an air conditioner using R410A incurs pressure higher than when using conventional refrigerant, it is necessary to choose adequate materials.• Thicknesses of copper pipes used with R410A are as shown in the table.• Never use copper pipes thinner than those indicated in the table even if they are available on the market. Thicknesses of Annealed Copper Pipes (R410A)Pipe outside diameter [mm (in.)]Thickness [mm]6.35 (1/4)0.809.52 (3/8)0.8012.70 (1/2)0.8015.88 (5/8) 1.0019.05 (3/4) 1.204.2. Pipe requirementCAUTION• Refer to the Installation Manual of the outdoor unit for description of the length of connecting pipe or for difference of its elevation.• Use pipe with water-resistant heat insulation.CAUTION• Install heat insulation around both the gas and liquid pipes.Failure to do so may cause water leaks.Use heat insulation with heat resistance above 120 °C.(Reverse cycle model only)In addition, if the humidity level at the installation location of the refrigerant piping is expected to exceed 70 %, install heat insulation around the refrigerant piping. If the expected humidity level is 70-80 %, use heat insulation that is 15 mm or thicker and if the expected humidity exceeds 80 %, use heat insulation that is 20 mm or thicker. If heat insulation is used that is not as thick as specified, condensation may form on the surface of the insulation. In addition, use heat insulation with heat conductivity of 0.045 W/(m·K) or less (at20 °C).4.3. Flare connection (pipe connection)WARNING• Tighten the flare nuts with a torque wrench using the specified tightening method. Otherwise, the flare nuts could break after a prolonged period, causing refrigerant to leak and generate a hazardous gas if the refrigerant comes into contact with a fl ame.4.3.1. Flaring• Use special pipe cutter and fl are tool exclusive for R410A. (1) Cut the connection pipe to the necessary length with apipe cutter.(2) Hold the pipe downward so that cuttings will not enter thepipe and remove any burrs.(3) Insert the fl are nut (always use the fl are nut attached tothe indoor and outdoor units respectively) onto the pipeand perform the flare processing with a flare tool.
