2Safety PrecautionsRead safety precautions before installationIncorrect installation due to ignoring instructions can cause serious damage or injury.The seriousness of potential damage or injuries is classified as either a WARNING or CAUTION.WARNINGFailure to observe a warning may result in death. The appliance must be installed inaccordance with national regulations.Failure to observe a caution may result in injury or equipment damage.CAUTIONWARNING Carefully read the safety precautions before installation. In certain functional environments, such as kitchens, server rooms, etc., the use of speciallydesigned air-conditioning units is highly recommended. Only trained and certified technicians should install, repair, and service this airconditioning unit. Improper installation may result in electrical shock, short circuit, leaks, fire, or other damage toequipment and personal property. Strictly follow the installation instructions set forth in this manual. Before you install the unit, consider strong winds, typhoons, and earthquakes that might affectyour unit and locate it accordingly. Failure to do so could cause damage to the unit. After installation, ensure there are no refrigerant leaks and that the unit is operating properly.Refrigerant is toxic and flammable and poses a serious health and safety risk.Note about Fluorinated Gasses1. This air conditioning unit contains fluorinated gasses. For specific information on the type of gasand the amount, please refer to the relevant label on the unit itself.2. Installation, service, maintenance, and repair of this unit must be performed by a certifiedtechnician.3. Product uninstallation and recycling must be performed by a certified technician.4. If the system has a leak-detection system installed, it must be checked for leaks at least every 12months.5. When the unit is checked for leaks, proper record-keeping of all checks is strongly recommended. Page 5

6Outdoor Unit InstallationOutdoor Unit Installation InstructionsStep 1: Select installation location The area must be free of combustible gasesand chemicals.The pipe length between the outdoor andindoor units must not exceed the maximumallowable pipe length.If possible, DO NOT install the unit where itwill be exposed to direct sunlight.If possible, make sure the unit is located faraway from your neighbors’ property so thatthe noise from the unit will not disturb them.If the location is exposed to strong winds (forexample, near a seaside), place the unitagainst the wall to shelter it from thewind. If necessary, use an awning(see Fig. 6.1 & 6.2).Install the indoor and outdoor units, cables,and wires at least 1 meter from televisions orradios to prevent static or image distortion.Depending on the radio waves, a 39.3 in (1 meter)distance may not be enough to eliminate allinterference.Outdoor UnitInstallationWhen choosing a location to install the outdoorunit, consider the following: Place the outdoor unit as close to the indoor unit as possible. Ensure that there is enough room for installation and maintenance. The air inlet and outlet must not be obstructed or exposed to strong wind. Ensure the location of the unit will not be subject to snowdrifts, accumulation of leaves,or other seasonal debris. If possible, providean awning for the unit. Ensure the awningdoes not obstruct airflow. The installation area must be dry and wellventilated. There must be enough room to install the connecting pipes and cables and to accessthem for maintenance.

7Refrigerant Piping ConnectionSafety PrecautionsWARNINGRefrigerant PipingConnection All field piping must be completed by alicensed technician and must comply withlocal and national regulations. When the air conditioner is installed in a smallroom, measures must be taken to prevent therefrigerant concentration in the room fromexceeding the safety limit in the event ofrefrigerant leakage. If the refrigerant leaksand its concentration exceeds its proper limit,hazards due to lack of oxygen may result. When installing the refrigeration system,ensure that air, dust, moisture, or foreignsubstances do not enter the refrigerant circuit.Contamination in the system may cause pooroperating capacity, high pressure in therefrigeration cycle, explosion, or injury. Ventilate the area immediately if there isrefrigerant leakage during the installation.Leaked refrigerant gas is both toxic andflammable. Ensure there is no refrigerantleakage after completing the installation work.CAUTIONDO NOT deform pipe while cutting. Be extracareful not to damage, dent, or deform the pipewhile cutting. This will drastically reduce theheating efficiency of the unit.1. Make sure the pipe is cut at a perfect90 angle. Refer to Fig. 7.1 for examples ofbad cuts.90 ObliqueStep 2: Remove burrsThe branching pipe must be installedhorizontally. An angle of more than 10 maycause malfunction. DO NOT install the connecting pipe until boththe indoor unit and the outdoor unit havebeen installed. Insulate the gas and liquid piping toprevent water leakage.Step1: Cut pipesFig. 7.1PipeReamerPoint down When preparing refrigerant pipes, take extracare to cut and flare them properly. This willensure efficient operation and minimize theneed for future maintenance.1. Measure the distance between the indoorand outdoor units.2. Using a pipe cutter, cut the pipe a littlelonger than the measured distance. Page 12 WarpedBurrs can affect the air-tight seal of the refrigerantpiping connection. They must be completelyremoved.1. Hold the pipe at a downward angle toprevent burrs from falling into the pipe.2. Using a reamer or deburring tool, removeall burrs from the cut section of the pipe.Refrigerant Piping Connection InstructionsCAUTIONRoughFig. 7.2Step 3: Flare pipe endsProper flaring is essential to achieve an airtight seal.1. After removing burrs from the cut pipe, sealthe ends with PVC tape to prevent foreignmaterials from entering the pipe.2. Sheath the pipe with insulating material.3. Place flare nuts on both ends of the pipe.Make sure they are facing in the rightdirection because you can’t put them onor change their direction after flaring(see Fig. 7.3).Flare nutCopper pipeFig. 7.3

8WiringSafety PrecautionsWARNING Wiring Be sure to disconnect the power supplybefore working on the unit.All electrical wiring must be doneaccording to local and national regulations.Electrical wiring must be done by aqualified technician. Improper connectionsmay cause electrical malfunction, injury,and fire.An independent circuit and single outletmust be used for this unit. DO NOT pluganother appliance or charger into thesame outlet. If the electrical circuit capacityis not enough or there is a defect in theelectrical work, it can lead to shock, fire,and unit and property damage.Connect the power cable to the terminalsand fasten it with a clamp. An insecureconnection may cause a fire.Make sure that all wiring is done correctlyand the control board cover is properlyinstalled. Failure to do so can causeoverheating at the connection points, fire,and electrical shock.Ensure that the main supply connection ismade through a switch that disconnectsall poles, with a contact gap of a least0.118 in (3 mm).DO NOT modify the length of the powercord or use an extension cord.CAUTION Connect the outdoor wires beforeconnecting the indoor wires.Make sure to ground the unit. Thegrounding wire should be away from gaspipes, water pipes, lightning rods,telephone wires, or other grounding wires.Improper grounding may cause electricalshock.DO NOT connect the unit with the powersource until all wiring and piping iscompleted.Make sure that you do not cross yourelectrical wiring with your signal wiring, asthis can cause distortion and interference. Page 14 Follow these instructions to prevent distortionwhen the compressor starts: The unit must be connected to the mainoutlet. Normally, the power supply musthave a low output impedance of 32 ohms.No other equipment should be connectedto the same power circuit.The unit’s power information can be foundon the rating sticker on the product.Outdoor Unit WiringWARNINGBefore performing any electrical or wiring work
