Safety Precautions The following safety precautions must be taken when using your air conditioner. WARNING • Risk of electric shock can cause injury or death. • Disconnect all remote electric power supplies before servicing, installing or cleaning. • Installation must be done by the manufacturer or service agent or a similar qualified person in order to avoid a hazard. Installing the unit The unit should not be installed by the user. Ask the dealer or authorized company to install the units.
Safety Precautions (Continued) Power supply line or circuit breaker If the power cable of this air conditioner is damaged, it must be replaced by service agent or similarly qualified persons in order to avoid a hazard. The unit must be plugged into an independent circuit if applicable or connect the power cable to the auxiliary circuit breaker. An all pole disconnection from the power supply must be incorporated in the fixed wiring with a contact opening of >3mm.
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.

Indoor Unit Installation It is recommended to install theY-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 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.
Purging the Unit Wet cloth On delivery, the indoor unit is loaded with inert gas. All this gas must therefore be purged before connecting the assembly piping. To purge the inert gas, proceed as follows. Unscrew the pinch pipe at the end of each refrigerant pipe. Result: All inert gas escapes from the indoor unit.
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.
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. Indoor temperature of 30°C and humidity of 85% is the standard condition. If install in a high humidity condition, use one grade thicker insulator by referring to the table below. If installing in an unfavorable conditions,use thicker one. Insulation’s heat-resistance temperature should be more than 120℃. Pipe Pipe size Liquid pipe ø6.35~ø9.52 ø12.
Drain pipe and Drain hose Installation Care must be taken when installing the drain hose for the indoor unit to ensure that any condensate water is correctly drained outside. The drain hose can be installed to the right or left side of the base pan. 1 Unscrew the 4 tapped screws to remove the cover of the drain hose connection port. 2 Insert the flexible hose to the drain hose port.
Drain pipe Connection Without the drain pump 1 Install horizontal drain pipe with a slope of 1/100 or more and fix it by hanger space of 1.0~1.5m. 2 Install U-trap at the end of the drain pipe to prevent a nasty smell to reach the indoor unit. 3 Do not install the drain pipe to upward position. It may cause water flow back to the unit. 1~1.
Drain pipe and Drain hose Installation (Continued) Centralized Drainage Without the drain pump Install horizontal drain pipe with a slope of 1/100 or more and fix it by hanger space of 1.0~1.5m. 2 Install U-trap at the end of the drain pipe to prevent a nasty smell to reach the indoor unit.
Testing the drainage Prepare a little water about 2 liters. 1 Pour water into the drain pan in the indoor unit as shown in figure. 2 Confirm that the water flows out through the drain hose. 3 When the drain pump is installed, operate the unit as cooling mode and check a drain pump pumping. 4 Drain pan Check drain water drops at the end of the drain pipe. Drain pipe Drain water drops 5 Make sure there is no water leak at the drainage. 6 Reassemble the cover of water supply intake.
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 ( ELCB or MCCB+ELB ) separated by the outdoor power. ELCB: Earth Leakage Circuit Breaker MCCB: Molded Case Circuit Breaker ELB: Earth Leakage Breaker 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.

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 SW03 SW04 The designs and shape are subject to change according to the model. SW05 SW06 SW07 Setting Main Address The MAIN address is for communication between the indoor unit and the outdoor unit.
