Safety Precautions (Continued) WARNING Hazards or unsafe practices that may result in severe personal injury or death. Stop the compressor before disconnecting the refrigerant pipe for pump-down operation. If you disconnect the refrigerant pipe while compressor is operating with service valve open, air inflow will cause excessive pressure in the refrigerant cycle that could lead to explosion and personal injury.
PREPARING FOR INSTALLATION Indoor Unit Outdoor Unit Where airflow is not blocked Where cool air can be distributed throughout the room Install the refrigerant piping length and the height difference of both indoor and outdoor units as indicated in the installation diagram Wall that prevents vibration and is strong enough to hold the product weight Out of the direct sunlight 1m or more away from the TV or radio (to prevent the screen from being distorted or noise from being generated) As far
PREPARING FOR INSTALLATION Accessories The following accessories are supplied with the air conditioner: Note The number of each accessory is indicated in parentheses. Accessories in the Indoor Unit Case Remote Control (1) Installation Plate (1) Batteries for Remote Control (2) User’s Manual (1) Installation Manual (1) ������ ����� The following connection accessories are optional. If they are not supplied, you should obtain them before installing the air conditioner.
INSTALLING THE AIR CONDTIONER You can select the direction of the drain hose depending on where you want to install the indoor unit. Therefore before fixing the installation plate to a wall or a window frame, you must determine the position of the 65mm hole through which the cable, pipe and hose pass to connect the indoor unit to the outdoor unit.
INSTALLING THE AIR CONDTIONER Connecting the Assembly Cable Torque(kgf.cm) Screw Unfasten Torque Tighten Torque M4 17~30 25~40 M5 20~35 30~50 Connecting the cable 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. 1 Extend the assembly cable if necessary.
ENGLISH INSTALLING THE AIR CONDTIONER 9 Connect the cables to the terminals as seen in the picture. Note Each wire is labeled with the corresponding terminal number. Indoor unit Indoor unit 1(L) 2(N) 1 F1 2 F2 F1 F2 Earth terminal Outdoor unit 1 2 F1 F2 1(L) 2(N) F1 F2 Outdoor unit CAUTION End of the wire must be circular. After connecting the cables, make sure terminal numbers on the indoor/outdoor unit matches.
INSTALLING THE AIR CONDTIONER 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.
INSTALLING THE AIR CONDTIONER ENGLISH 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. Unscrew the caps at the end of each pipe. Result: All inert gas exhausts from the indoor unit.
INSTALLING THE AIR CONDTIONER Cutting or Extending the Pipe 1 Make sure that you have all 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 (see below examples of correct and incorrect cut edges). Pipe cutter Oblique Rough Burr Pipe 3 To prevent a gas leak, remove all burrs at the cut edge of the pipe using a reamer.
INSTALLING THE AIR CONDTIONER ENGLISH Installing and Connecting the Drain Hose of the Indoor Unit When installing the drain hose for the indoor unit, check if condensation draining is adequate. When passing the drain hose through the 65-mm hole drilled in the wall, check the followings: Wall Indoor unit Drain hose The drain hose must NOT slant upwards. The end of the drain hose must NOT be placed under water. 5cm less The drain hose must not be bent.
INSTALLING THE AIR CONDTIONER Changing Direction of the Drain Hose Change the direction only when it is necessary. 1 Detach the rubber cap with the flyer. 2 Detach the drain hose by pulling it and turning to the left. 3 Insert the drain hose by fixing it with the screw into the groove of the drain hose and the outlet of the drain pan. 4 Attach the rubber cap with a screwdriver by turning it to the right until it fixes to the end of the groove.
INSTALLING THE AIR CONDTIONER ENGLISH Assigning Address to Indoor Unit Before installing the indoor unit, assign an address to the indoor unit according to the air conditioning system plan. 1 Open the front grille by pulling on the tabs on the lower right and left sides of the indoor unit. 2 Remove the screw securing the cover PCB. 3 Remove the cover PCB. 4 The address of the indoor unit is assigned by adjusting MAIN(SW02).
COMPLETING THE INSTALLATION 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 Pipes 1 To avoid condensation problems, wrap foam insulation (as shown in the figure A) on a part without insulation on the end of the pipes. 2 Wind the pipe, assembly cable and drain hose with vinyl tape.
COMPLETING THE INSTALLATION ENGLISH Final Check and Trial Operation To complete the installation, perform the following checks and tests to ensure that the air conditioner operates correctly.
COMPLETING THE INSTALLATION Providing Information for User After finishing the installation of the air conditioner, explain the followings to the user: 1 How to start and stop the air conditioner 2 How to select the modes and functions 3 How to adjust the temperature and the fan speed 4 How to adjust the airflow direction 5 How to set the timers 6 How to clean and replace the filters Note When you complete the installation successfully, hand over the User’s Manual and this Installation Ma
