Safety Precautions (Carefully follow the precautions listed below because they are essential to guarantee the safety of the equipment.) WARNING • Always disconnect the air conditioner from the power supply before servicing it or accessing its internal components. • Verify that installation and testing operations are performed by qualified personnel. • Verify that the air conditioner is not installed in an easily accessible area.
Safety Precautions (Continued) CAUTION Make sure that you earth the cables. - Do not connect the earth wire to the gas pipe, water pipe, lighting rod or telephone wire. If earthing is not complete, electric shock or fire may occur. Install the circuit breaker. - If the circuit breaker is not installed, electric shock or fire may occur. Make sure that the condensed water dripping from the drain hose runs out properly and safely.
Accessories The following accessories are supplied with the indoor unit. The type and quantity may differ depending on the specifications.
Selecting the Installation Location Indoor Unit There must be no obstacles near the air inlet and outlet. Install the indoor unit on a ceiling that can support its weight. Maintain sufficient clearance around the indoor unit. Make sure that the water dripping from the drain hose runs away correctly and safely. The indoor unit must be installed in this way, that they are out of public access. (Not touchable by the users) Rigid wall without vibration. Where it is not exposed to direct sunshine.

Indoor Unit Installation It is recommended to install the Y-joint before installing the indoor unit. 1 Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit. Note Concrete 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 maintain the correct dimensions between the markings.
4 Nut Screw eight nuts to the suspension bolts making space for hanging the indoor unit. CAUTION 5 Washer You must install the suspension bolts more than four when installing the indoor unit. Rubber 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. 6 Fasten the nut Adjust the height of the indoor unit by using the gauge of dimensions.
Purging the Unit From factory the unit is supplied and set with a pre-charge of nitrogen gas (insert gas). Therefore, all insert gas must be purged before connecting the assembly piping. Unscrew the pinch pipe at the end of each refrigerant pipe. Gas refrigerant port Result: All inert gas escapes from the indoor unit. Note To prevent dirt or foreign objects from getting into the pipes during installation, do NOT remove the pinch pipe completely until you are ready to connect the piping.
Connecting the Refrigerant Pipe There are two refrigerant pipes of differing diameters: A smaller one for the liquid refrigerant A larger one for the gas refrigerant The inside of copper pipe must be clean & has no dust. 1 Before connecting the reprigerant pipe, open the cover side. 2 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. Outer Diameter [mm(inch)] 6.
Cutting/Flaring the Pipes 1 Make sure that you prepared the required tools. (pipe cutter, reamer, flaring tool and pipe holder) 2 If you want to shorten the pipe, cut it using a pipe cutter ensuring that the cut edge remains at 90° with the side of the pipe. There are some examples of correctly and incorrectly cut edges below. Oblique Rough Burr 3 To prevent a gas leak, remove all burrs at the cut edge of the pipe using a reamer. 4 Carry out flaring work using flaring tool as shown below.
Performing Leak Test & Insulation Leak test LEAK TEST WITH NITROGEN (before opening valves) In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R410A, it’s responsible of installer to pressurize the whole system with nitrogen (using a pressure regulator) at a pressure above 4.1MPa (gauge). LEAK TEST WITH R410A (after opening valves) Before opening valves, discharge all the nitrogen into the system and create vacuum.
Performing Leak Test & Insulation (Continued) 5 Select the insulation of the refrigerant pipe. Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. The thickness according to the pipe size is a standard of the indoor temperature of 27°C and humidity of 80%. If installing in an unfavorable conditions, use thicker one. Insulator’s heat-resistance temperature should be more than 120°C.
Drain pipe and Drain Hose Installation Care must be taken when installing the drainpipe and drain hose for the indoor unit so that condensate water is drained correctly outside. 1 Fix the flexible hose to the drainpipe. The connection port of the flexible hose and PVC drainpipe must be fixed with PVC adhesives. Drainpipe Flexible hose AVXC1 AVXCS Check out that the connected part doesn’t leak.
Drain pipe and Drain Hose Installation (Continued) Drainpipe Connection Flexible hose Installation 1 The drain pipe should be installed within 100mm from the flexible hose, lift up from 100mm to 550mm and lift down 20mm or more. 2 Install horizontal drainpipe with a slope of 1/100 or more and fix it by hanger space of 1~1.5m. 3 Install the air vent in the horizontal drainpipe to prevent water flow back to the indoor unit.
Testing the Drainage You should test drainage after completing the installation. Prepare a little water about 1.0 liter. 1 Open the cover water supply intake. 2 Pour water into the water supply intake. 3 Operate the unit in the Cool mode and check a drain pump pumping. 4 Check drain water drops at the end of the drainpipe. AVXC1/AVXCS Air outlet Leveler AVXC2 Drainpipe Drain water drops 5 Make sure there is no water leak at the drainage.
Wiring Work Power and communication cable connection 1 Before wiring work, you must turn off all power source. 2 Indoor unit power should be supplied through the breaker(MCCB, ELB) separated by the outdoor power. 3 The power cable should be used only copper wires. 4 Connect the power cable{1(L), 2(N)} among the units within maximum length and communication cable(F1, F2) each. 5 Connect V1, V2(for DC12V) and F3, F4(for communication) when installing the wired remote Control.

Refer to each installation manual about the rating current of indoor unit.
Wiring Work (Continued) CAUTION Select the power cable in accordance with relevant local and national regulations. Wire size must comply with local and national code. For the power cable, use the grade of H07RN-F or H05RN-F materials. You should connect the power cable into the power cable terminal and fasten it with a clamp. The unbalanced power must be maintained within 10% of supply rating among whole indoor units.
Indoor Unit Setting 1 Before installing the indoor unit, assign an address to the indoor unit according to the air conditioning system plan. 2 The address of the indoor unit is assigned by adjusting MAIN(SW01, SW02) and RMC(SW03, SW04) rotary switches. SW01 SW02 K1 K2 K3 K4 SW03 K5 K6 K7 K8 SW04 K9K10K11K12 The designs and shape are subject to change according to the model. Setting MAIN Address The MAIN address is for communication between the indoor unit and the outdoor unit.
