Fixing the installation plate 2. Fix the indoor unit. If you fix the indoor unit on a wall (1) Fix the installation plate to the wall giving attention to the weight of the indoor unit. • I f you mount the plate to a concrete wall using plastic anchors, make sure that gaps between the wall and the plate, created by projected anchor, is less than 20mm.
When you install the unit, make first refrigerant connections and then electrical connections. Connect the air conditioner to grounding system before performing the electrical connection. If unit is uninstalled, first disconnect electrical cables, then refrigerant connections. ENGLISH If the outdoor unit is more than 5 meters away from the indoor unit, you must extend the cable. The maximum length of the cable is 15(09/12)/20(18/24) meters. 1. Extend the assembly cable if necessary.
Installing and connecting the assembly pipe of the indoor unit Connect indoor and outdoor units with field-supplied copper pipes by means of flare connections. Use insulated seamless refrigeration grade pipe only, (Cu DHP type according to ISO1337), degreased and deoxidized, suitable for operating pressures of at least 4200 kPa and for burst pressure of at least 20700 kPa. Under no circumstances must sanitary type copper pipe be used.
Purging the indoor unit The indoor unit is supplied with inert gas (nitrogen). Before installing the unit, check if nitrogen gas flow out of indoor unit. If this one isn’t true, DO NOT INSTALL THE UNIT since leakage could be inside the indoor unit. ENGLISH 1. Unscrew the caps at the end of each pipe. All inert gas exhausts from the indoor unit.
Cutting or extending the pipe 5. Check if you flared the pipe correctly (see examples of incorrectly flared pipes below). Correct Inclined Damaged Surface Cracked Uneven Thickness 6. Align the pipes to connect them easily. Tighten the flare nuts first with your hands, and then with a torque wrench, applying the following torque: Outer Diameter ø6.35 mm ø9.52 mm ø12.70 mm ø15.88 mm ø19.05 mm ø22.
Drain hose installation 1. If necessary, connect the 2-meter extension drain hose to the drain hose. 2. If you use the extension drain hose, insulate the inside of the extension drain hose with a shield. 3. Fit the drain hose into 1 of 2 drain hose holes, then fix the end of the drain hose tightly with a clamp. • If you do not use the other drain hose hole, block it with a rubber stopper. ENGLISH 4.
Installing and connecting the drain hose of the outdoor unit While heating, ice may accumulate. During the process of defrosting, check if condensation draining is adequate. For adequate draining, do the following: 1. Insert the drain plug into the drain hole on the underside of the outdoor unit. • T o avoid drain plug from contacting the ground, secure gap between the ground and the bottom surface of the outdoor unit. Drain hole Drain plug Bottom surface of outdoor unit 2.
3. Connect the charging hose of the low-pressure side of manifold gauge to a gas service port as seen in the picture. 4. Open the valve of the low pressure side of manifold gauge counterclockwise. 5. Purge the air in the connected pipes using the vacuum pump for about 15 minutes. Valve Gas service port ENGLISH Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about Manifold gauge 10 minutes. This procedure is very important to avoid a gas leak.
Purging the connected pipes Important information regulation regarding the refrigerant used This product contains fluorinated greenhouse gases covered by the Kyoto Protocol. Do not vent gases into the atmosphere. 1. Please fill in with indelible ink, Refrigerant type R410A GWP value 1975 GWP=Global Warming Potential Contains fluorinated greenhouse gases covered by the Kyoto Protocol.
Performing the gas leak tests Make sure to check for gas leaks before completing the installation process (connecting the assembly pipe and hose between indoor unit and outdoor unit, insulating the cables, hose and pipe, and fixing the indoor unit to the installation plate). C ENGLISH A D B To check for gas leaks on the outdoor unit, Check the valve A and B using a leak detector. To check for gas leaks on the indoor unit, Check the flare nut C and D using a leak detector.
Fixing the indoor unit in place Perform the following work on the area where gas leak test was done priorly. After checking for gas leaks in the system, insulate the pipe, hose and cables. Then place the indoor unit on the installation plate. Insulation 1. To avoid condensation problems, wrap foam insulation (as shown in the figure) on a part without insulation on the end of the pipes. Pipes 2. Wind the pipe, assembly cable and drain hose with vinyl tape. 3.
Final Check and Trial Operation To complete the installation, perform the following checks and tests to ensure that the air conditioner operates correctly. 1.
