[. . . ] installation manual Split Type Room Air Conditioner Congratulations Congratulations and thank you for choosing a splittype air conditioner. Before you use the air conditioner, we recommend that you read through the entire user manual, which provides the description of the air conditioner and its functions. To avoid the risks that are always present when you use an electrical appliance, it is important that the air conditioner is installed correctly and that you read the safety instructions carefully to avoid misuse and hazards. We recommend that you keep this instruction booklet for future reference and pass it on to any future owners. [. . . ] (a)  ull out the drain cap at the rear right of P the indoor unit.

Piping on the rear right side Drain hose from the left side Piping on the left side Drain hose from the left side Drain hose from the left side 11 • Do not route both refrigerant piping and drain hose from the right side to the left side to prevent big gap between the indoor unit and the wall. • Turn lightly the cable to make the connection easier later. • Be sure that the drain hose is located at the lowest side of the buddle. Locating at the upper side can cause drain pan to overflow inside unit. Drain hose from the right side Piping and cable from the right side • Never cross connect or interwind the power wire with any other wiring. • Do not allow the piping to be exposed out from the back of the indoor unit. • If part of the drain hose is positioned inside the room, wrap it with insulating materials so as to prevent condensed water from dropping. 5 Hang the mounting slots of the indoor unit on the upper hooks of the mounting plate and check if it is firm enough . To ease the piping installation, put a spacer between the indoor unit and the wall. 4 Take out the piping from body case, wrap the piping, power cords, drain hose with the tape and then make them pass through the piping hose. Do not put any object in the drain pan located in the rear of the indoor unit, as the condensed water is gathered there and piped out of the room. Indoor Unit Remove the spacer once finished. Upper hook Mounting plate Spacer Liquid pipe Connecting cable Piping insulation 6 Press the lower left and right sides of the unit against the mounting plate until the lower hooks engage into their slots. Upper hook Drain hose Gas pipe Connecting cable caution • Connect the indoor unit first, then the outdoor unit. That must be done later. Drain hose Mounting plate Fixing lower hook 7 The installation site should be 2. 3 meters or more above the floor. 12 Step 5: Installation of Connection Pipe Refrigerant pipe connection 1 Flaring work Main cause for refrigerant leakage is due to defects in the flaring work. Carry out correct flaring work using the following procedure: A: Cut the pipes and the cable. • Use the piping kit accessory (if applicable) or pipes purchased locally. Pipe Copper pipe Bar Flare nut Copper tube caution It is not possible to put them on after flaring work. • Carry out flaring work using flaring tool as shown below. Handle Bar Yoke Cone Clamp handle Red arrow mark Oblique Roughness Burr • Firmly hold copper pipe in a die according to the dimension shown in the table below. 0. 7 1. 0 1. 0 2. 2 B: Burr removal • Completely remove all burrs from the cut cross section of pipe/tube. • Face the end of the copper pipe/tube in a downward direction as you remove burrs in order to avoid burrs dropping into the tubing. Pipe Reamer Face down Ф12 ~ 12. 70 Ф16 ~ 15. 88 E: Check • Compare the flare work with the adjacent diagram. • If the pipe has any defect, cut off the enlarged section and redo the work. Smooth all around Improper flaring C: Putting flare nut on • Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal. Inclined Even length all around Damaged Cracked Uneven surface thickness • Make an independent covering for each pipe with the appropriate tubular isolation. 13 Step 6: Piping Connection - Indoor Unit A: Connecting the indoor unit tubing to the connection piping: • Align the centers of the pipes and sufficiently tighten the flare nut with your hands first. B: Wrap the insulation material around the connecting portion: • Cover the indoor unit pipe and the connection pipe with the heat insulation material. Bind them together with vinyl tape so that there is no gap. Cable ties Insulation material Indoor unit tubing Flare nut Pipings • Ensure to Isolate separately the suction pipe from the liquid pipe. Spanner Torque wrench Heat insulation Spanner (fixed) Flare nut wrench Torque Indoor unit tubing Pipings Suction line pipe Liquid line pipe • Wrap the insulated pipes with vinyl tape in the rear section for pipe housing. [. . . ] • When relocate the unit to another place, performevacuation using vacuum pump. • Make sure the refrigerant added into the air conditioner is in liquid form in any case. Refer to the valve cap tightening torque value as below: Outer diam.
