radio, when install indoor and ou tdoor unit, connecting wire and power line. (If the radio wave is relatively strong, 1 m is not enough to reduce noise). Don't install unit in following places: (a) Oil mist or oil gas exists, such as kitchen, or, plastic parts may got aged, or water leakage. (b) Where there is corrosive gas. Copper tube and welded part may be damaged due to corrosion, causing leakage. (c) Where there is strong radiation. This will affect unit's control system, causing malfunction of the unit (d) Where flamable gas, dirt, and volatile matter (thinner, gasoline) exist, These matter might cause fire accident. Refer to paper pattern when installing unit. Cautions for the installation personnel Don't fail to show customers how to operate unit. 19 Installation Procedure 1 BEFORE INSTALLATION Determine the way to carry unit to installation place. Don't remove packing until unit reaches installation place. If unpacking is unkavoidable, protect unit properly. 2 SELECTION OF INSTALLATION PLACE (1) Installation place shall meet the following and agreed by customers: Place where proper air flow can be ensured. No block to air flow. Water drainage is smpoth. Place strong enough to support unit weight. Place where inclination is not evident on ceiling. Enough space for mainenance. Indoor and outdoor unit piping length is within limit. (Refer to Installation Manual for outdoor unit.) Indoor and outdoor unit, power cable, inter unit cable are at least 1 m away fromT.V. radop. This is helpful to avoid picture disturbance and noise. (Even if 1 m iskept, noise can still appear if radio wave is strong) (2) Ceiling height Indoor unit can be installed on ceiling of 2.5-3m in height. (Refer to Foeld setting and Installation Manual of ornament panel.) (3) Install suspending bolt. Check if the installation place is strong enough to hold weight. Take necessary measures in case it is not safe. (Distance between holes are marked on paper pattern. Refer to paper pattern for place need be reinforced) Installation space (For series 182 ) 1500 1500 310H Air outlet Air outletAir inlet (For series 242, 282, 362, 522, 482, 602 ) 1500 Over 1500 Over Air outlet Air inlet Air inlet Air inlet Air outlet 2500 Over Air outlet 1500 Over1500 Over 260260 20 Installation Procedure PREPARATION FOR THE INSTALLATION (1) Position of ceiling opening between unit and suspending bolt.

(160) 20 Over Connect all pipings (refrigerant, water drainage), wirings (inter unit cable) to indoor unit, before installation. Cut a hole in ceiling, may be a frame should be used to ensure a smooth surface and to prevent vibration. Contact your real estate dealer (3) Install a suspending bolt. (Use a M10 bolt) To support the unit weight, anchor bolt shall be used in the case of already exists ceiling. For new ceiling, use built-in type bolt or parts prepared in the field. Before going on installing adjust space between ceiling. Ceiling 50~100 Roof Anchor bolt Long nut Suspending bolt Note: All the above mentioned parts shall be prepared in field. 21 Installation Procedure 4 INSTALLATION OF INDOOR UNIT In the case of new ceiling (1) Install unit temporally Put suspending bracket on the suspending bolt. Be sure to use nut and washer at both ends of the bracket. (2) As for the dimensions of ceiling hole, see paper pattern. Ask your real estate dealer for details. Center of the hole is marked on the paper pattern. Center of the unit is marked on the card in the unit and on the paper pattern. Mount paper pattern 5 onto unit using 3 screws 6 . Fix the corner of the drain pan at piping outlet. < After installation on the ceiling > (3) Adjust unit to its right position. (Refer to preparation for the installation-(1)) (4) Check unit's horizontal level. Watert pump and flating switch is installed inside indoor unit, check four corners of the unit for its level usi...
