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 Choosing the Installation Location (Continued) Space Requirements for Outdoor Unit When installing 1 outdoor unit Unit : mm When the air outlet is towards the wall 1500 or more 300 or more When the air outlet is opposite the wall When 3 sides of the outdoor unit are The upper part of the outdoor unit and 2000 or more 600 or more 150 or more The upper part of the outdoor unit and When the walls are blocking front and the rear side of the outdoor unit

PREPARING FOR INSTALLATION Accessories The following accessories are supplied with the air conditioner: Note The number of each accessory is indicated in parentheses.
INSTALLING THE AIR CONDTIONER ENGLISH Fixing the Installation Plate 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 Cable specification Model 09/12 18 24 Power cable 3G, 1.0mm2 H07RN-F 3G, 2.5mm2 H07RN-F 3G, 2.5mm2 H07RN-F Interconnection cable 3G, 1.0mm2 H07RN-F 3G, 2.5mm2 H07RN-F 3G, 2.5mm2 H07RN-F Type GL 20A 25A Connect the power cable to the auxiliary circuit breaker. If every pole fails to connect to the power supply, it must be incorporated in a wire with a contact opening of ≥3mm.
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 24 09/12/18 Indoor unit Indoor unit N(1) 1 N(1) 1 Ground wire (Green/Yellow) Outdoor unit N(1) 1 Ground wire (Green/Yellow) N(1) 1 Outdoor unit CAUTION Ground wire (Green/Yellow) Outdoor unit Ground wire (Green/Yellow) End of the wire must be circular.
INSTALLING THE AIR CONDTIONER Installing and Connecting the Assembly Pipe of the Indoor Unit There are 2 refrigerant pipes of different diameters: The smaller one is for the liquid refrigerant The larger one is for the gas refrigerant A short pipe is already fitted to the air conditioner. You may need to extend the pipe using the assembly pipe (optional).
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 A 5-meter pipe is supplied with the air conditioner (optional NOT FOR ITALY). The length of the pipe can be: Extended up to : see table page 5 Shorten up to: see page 5 CAUTION If you need a pipe longer than 5 meters: You must extend the assembly cable. You must add refrigerant to the pipes; otherwise, the indoor unit may freeze. 1 Make sure that you have all the required tools (pipe cutter, reamer, flaring tool and pipe holder).
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.
COMPLETING THE INSTALLATIONR ENGLISH Purging the Connected Pipes CAUTION When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.
COMPLETING THE INSTALLATION Purging the Connected Pipes (Continued) Adding Refrigerant Add refrigerant charge according to table below: Model 09 12 18 24 A 10 20 20 25 If you use a pipe... longer than 5 meters, shorter than 5 meters, Then... 'A'g of refrigerant R22 must be added for each extra metre. The purge time is normal. Refer to the Service Manual for further details.
COMPLETING THE INSTALLATION ENGLISH 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. 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 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 ENGLISH 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 Instal
