When deciding on the location of the air conditioner the following restrictions must be taken into account. 1 Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit. ࡛ Do not hold the discharge while carrying the indoor unit to avoid the possibility of breakage. ࡛ You must hold the hanger plate on the corner and carry the indoor unit. Installation Procedure NOTE ࡛ Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity. For this reason, before drilling the holes, be sure to maintain the correct dimensions between the markings. 2 Insert bolt anchors, use existing ceiling supports or construct a suitable support as shown in figure. Concrete Hole in anchor Hole in plug Insert Suspension bolt (ø9.52 or M10) 26 English 3 Install the suspension bolts, depending on the ceiling type. 6 Check the level of the indoor unit by using a leveler. ࡛ A tilt of the indoor unit may cause malfunction of a built-in float switch and water leaks. Ceiling support Level 7 Adjust the unit to the appropriate position, taking into account the installation area for the front panel. ࡛ If this is not possible, create an opening on the false ceiling in order to be able to use it to perform the required operations on the indoor unit. 4 Screw eight nuts and washers to the suspension bolts, making space for hanging the indoor unit. CAUTION ࡛ Adjust the space between the ceiling and the indoor unit by using a dimension gauge. ࡛ Fix the indoor unit securely after adjusting the level of the unit by using a leveller. ࡛ Remove the pattern sheet and install the front panel. Air outlet side Air inlet side Indoor unit 10 ࡛ If the length of the suspension bolt is more than 1.5 m, you are required to prevent vibration. ࡛ Place the pattern sheet on the indoor unit. 10 CAUTION ࡛ Make sure that the ceiling is strong enough to support the weight of the indoor unit. Before hanging the unit, test the strength of each attached suspension bolt. Jig Ceiling ࡛ You must install all of the suspension rods. Installation Procedure ࡛ It is important to leave sufficient space in the false ceiling to allow access for maintenance or repairs to the drainage pipe connection, the refrigerant pipe connection, or to remove the unit if necessary. 5 Hang the indoor unit to the suspension bolts between two nuts. Screw the nuts to suspend the unit. Cut a pad stopper and place it on the bracket at this time. 2 1 2 English 27 Installation Procedure Step 5 Purging inert gas from the indoor unit 3 To prevent any gas from leaking out, remove all burrs at the cut edge of the pipe, using a reamer. 4 Slide a flare nut on to the pipe and modify the flare. D A 90° ±2° Unscrew the pinch pipe at the end of each refrigerant pipe. 45° ± 2° The indoor unit comes with nitrogen gas (inert gas) charged at the factory.

Step 6 Cutting and flaring the pipes 1 Make sure that you have the required tools available: pipe cutter, reamer, flaring tool, and pipe holder. Installation Procedure 2 If you wish to shorten the pipes, cut them with a pipe cutter, ensuring that the cut edge remains at a 90° angle to the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly. Pipe cutter Pipe 28 English Oblique Rough Burr Correct Inclined Damaged Surface Cracked Uneven Thickness Step 7 Connecting the assembly pipes to the refrigerant pipes There are two refrigerant pipes of different diameters : ࡛ A smaller one for the liquid refrigerant. ࡛ A larger one for the gas refrigerant. The inside of copper pipe must be clean and has no dust. 1 Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, first manually and then with a torque wrench, a spanner applying the following torque. NOTE ࡛ If the pipes must be shortened, see Step 6 Cutting and flaring the pipes on page 28. 2 Be sure to use an insulator thick enough to cover the refrigerant tube to protect the condensate water on the outside of the pipe falling onto the floor and to improve the efficiency of the unit. 3 Cut off any excess foam insulation. 4 Make sure that there are no cracks or waves on the bent area. 5 It would be necessary to double the insulation thickness (10 mm or more) to prevent condensation even on the insulator when if the installed area is warm and humid. 1 6 Do not use joints or extensions for the pipes connecting the indoor and outdoor units. The only permitted connections are those for which the units are designed. 2 CAUTION Spanner 3 Flare nut Outer Diameter (mm) ƟͱθαЇʪ࣑Ęࡻ͔࣒ Ø6.35 14 to 18 Ø9.52 34 to 42 Ø12.70 49 to 61 Ø15.88 68 to 82 ࡛ For sizing and limits (height difference, line length, max. bends, refrigerant charge, etc.) see the outdoor unit installation manual. ࡛ All refrigerant connection must be accessible, in order to permit either unit maintenance or removing it completely. ࡛ If the pipes require brazing, make sure that oxygen free nitrogen (OFN) is flowing through the system. ࡛ Nitrogen blowing pressure range is 0.02 to 0.05 MPa. (1 Nࡻm = 10 kgfࡻcm) English 29 Installation Procedure Union 3 Torque wrench ࡛ Connect the indoor and outdoor units using pipes with flared connections (not supplied). For the lines, use insulated, unwelded, degreased and deoxidized copper pipe (Cu DHP type to ISO 1337 or UNI EN 127351), suitable for operating pressures of at least 4.2 MPa and for a burst pressure of at least 20.7 MPa. Copper pipe for hydro-sanitary applications is completely unsuitable. Installation Procedure Step 8 Performing the gas leak test To identify potential gas leaks on the indoor unit, inspect the connection area of each refrigerant pipe using a leak detector for R-410A. Before recreating the vacuum and recirculating the refrigerant gas, pressurize the whole system with nitrogen (using a cylinder with a pressure reducer) at a pressure above 4.1 MPa in order to immediately detect leaks on the refrigerant fittings. 4 The pipes and electrical cables connecting the indoor unit with the outdoor unit must be fixed to the wall with suitable ducts. Insulation cover pipe Insulation pipe Indoor unit Made vacuum for 15 minutes and pressurizing system with nitrogen. Be sure to overlap the insulation. CAUTION Insulator ࡛ Make sure that all refrigerant connection must be accessible for easy maintenance and detachment. Liquid side ࡛ Must fit tightly against body without any gap. Gas side ࡛ Install the insulation not to get wider and use the adhesives on the connection part of it to prevent moisture from entering. ࡛ Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight. Step 9 Insulating the refrigerant pipes Once you have checked that there are no leaks in the system, you can insulate the piping and hose. 1 To avoid condensation problems, place Acrylonitrile Butadien Rubber separately around each refrigerant pipe. ࡛ Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe. ࡛ Add the additional insulation if the insulation plate gets thinner. Hanger Installation Procedure Additional insulation No gap a ax3 NBR (T13.0 or thicker) NOTE ࡛ Always make the seam of pipes face upwards. 2 Wind insulating tape around the pipes and drain hose avoiding compressing the insulation too much. 3 Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit. 30 English Refrigerant pipe insulation ࡛ Must fit tightly against body without any gap. ࡛ All refrigerant connection must be accessible, in order to permit either unit maintenance or removal. 5 Select the insulation of the refrigerant pipe. ࡛ Insulate the gas side and liquid side pipe, noting the insulation thickness that must differ according to the pipe size. ࡛ Standard: Less than an indoor temperature of 30°C, with humidity at 85%. If installing in a high humidity environment, use one grade thicker insulator by referring to the table below. If installing in an unfavourable environment, use thicker one. ࡛ The heat-resistance temperature of the insulator must be more than 120°C. Insulation Type (Heating/Cooling) Pipe Pipe size Standard [30°C, 85%] High humidity [30°C, over 85%] Remarks ࡛ When installing insulation in the places and conditions below, use the same insulation that is used for high humidity conditions. <Geological condition> High humidity locations such as shorelines, hot springs, lake or riversides, and ridges (when part of the building is covered by earth and sand) <Operation purpose condition> Restaurant ceiling, sauna, swimming pool etc. <Building construction condition> Ceilings frequently exposed to moisture and cooling are not covered.
