[. . . ] installation manual Split Type Room Air Conditioner Congratulations Congratulations and thank you for choosing a splittype air conditioner. We are sure you will find your new air conditioner a pleasure to use. 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. [. . . ] • 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. • Do not plug the cable to the indoor 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. • Measure the distance between the indoor and the outdoor unit. • Cut the pipes a little longer than the measured distance. • Cut the cable 1. 5m longer than the pipe length. 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. (mm) Ф6 ~ 6. 35 Ф9. 52 (3/8”) A (mm) Max. 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. [. . . ] 9 Securely tighten the stem cap. Outdoor Unit Multimeter -76cmHg Lo Handle Charging hose Low pressure valve Test and Running Gas Leakage Check 1 Soap water method: Apply soap water or liquid neutral detergent on all valves and pipe connections (A, B, C and D, refer to the figure below) involved in installation by a soft brush to check for leakage. If bubbles come out, the pipes have leakage. Indoor unit check points D C Liquid pipe Gas pipe Outdoor Unit 2-way valve 3-way valve B A Outdoor unit check points 2 Leak detector Use the leak detector to check for leakage. Electrical Safety Check Perform the electric safe check after completing the installation: 1 Earthing work After finishing earthing work, measure the earthing resistance by visual detection and earthing resistance tester. Manifold valve Hi Handle Charging hose 2 Electrical leakage check (performing during test running) During test operation after finishing installation, the service person can use the electric probe and multimeter to perform the electrical leakage check. Turn off the unit immediately if refrigerant leakage happens. Check and find out the solution ways till the unit operate properly. Vacuum Pump 21 Operation Test 1 Before Operation Test • Do not s witch on power before installation is finished completely. [. . . ]
