(when ceiling already exists.) Refer to paper pattern for dimension of ceiling hole. 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 using horizontal compartor or PVC tube with water. (If unit is tilting against the direction of water drainage, problem may occur on floating switch, causing water leakage.) (5) Remove the washer mounlting 2 , and tighten the nut above. Nut (Prepare in feild) (6) Remove the paper pattern. Washer (Prepared in feild) In the case of ceiling already exists (1) Install unit temporally Put suspending bracket on the suspending bolt. Be sure to use nut and washer at both ends of the bracket. Fix the bracket firmly. Suspending bolts (Refer to preparation for the installation (1) ). (2) Adjust the height and position of the unit. 3 Fasten (double nuts) (3) Proceed with and 4 of "In the case of new ceiling".

Outdoor is precharged with refrigerant. Be sure to see the Fig.1, when connecting and removing piping from unit. For the size of the flare nut, please refer to Table 1. Apply refrigerant oil at both inside and outsid of lflare nut. Tighten it band tight 3-4 turns then tighten it. Use torque specified in Table 1. (Too much force may damage flare nut, causing gas leakage). Check piping joints for gas leakage. Insulate piping as shown in Fig. below. Cover joint of gas piping and insulator 7 with seal.

If downward slope can't be made, take other measures to lift it up. Keep a distance of 1-1.5m between suspending brackets, to make water hose straight. Slope over 1/100 1-1.5m Use the self-provided stiff pipe and clamp with unit. Insert water pipe into water plug until it reaches thewhite tape. Tighten the clip until head of the screw is less than 4mm from hose. Wind the drain hose to the clip using seal pad 9 . Insulate drain hose in the room. 1 Clamp Tape (White) Self-provided stiff pipe 4mm below (accessory) (accessory) Large size seal pad Clamp 10 Installation height shall be less than 280mm.
