[. . . ] In order to utilize the static pressure characteristics of the air supply in the indoor unit, design the duct branching by setting size up to the air supply chamber or by setting length to the first branch as long as possible (Min: 200mm or longer) so that an even air volume can be obtained. Especially, when setting the branching point just after air supplying of the indoor unit, air concentrates at the center part and air is difficult to flow to the ducts at both sides. Connect each connecting section surely, and apply sufficient thermal insulation. In this model which the duct is branched in the ceiling, compared with the general houses, the high temperature generates on the periphery in the cooling time (Especially, at attic and etc. ), temperature difference increases between the supply air and outside of the duct, and dewing may occur. Dewing on the surface of the thermal insulator covering exposure of the metal connecting section or leaking portion of the cooling air may cause a trouble such as falling of water drop. Thermal insulation of screwing sections is necessary. Avoid dewing by applying thermal insulation to 6 screws which fix the duct flange of the air supply chamber. · For duct parts, the flexible branch duct (thermal insulation, 25mm or more thickness) is recommended. · Adjust the duct length to 6m or less even for straight pipe, and avoid sudden bending (Part resistance is large. ) if bending.

Piping and Cautions · Set drain side of pipe at downward slope. (1/100 or more) · Be sure to apply thermal insulation (foaming polyethylene, 10mm-thickness or more) for pipes passing through the room. · Adhere the connecting sections with vinyl chloride agent surely so that no water leakage is caused. · Support the piping with hanging bracket so that force is not applied to connection sections of pipe and pipe is not waved with connected pipes. Trap Fig. 9-5-1 · As shown in the figure, set the collective piping such as the ceiling duct so that waste water does not back up from the main pipe. NOTES : · Do not make slack or trap at halfway of pipes. · Set pipes so that the end of drain pipe is not dipped in water, and also keep space with 50mm or more to the ground. · After piping work, check water drains smoothly. · Hole should be made at a slight downward slant to the outdoor side. · When connecting extension drain hose, insulate the connecting part of extension drain hose with shield pipe. 50 mm or more Do not put the drain hose end into water or drainage ditch.

If it is pulled exceedingly, an abnormal sound may be caused. 1 2 3 ­ 53 ­ No. 2 Part name Electrical parts assembly Procedure 1) Remove two fixing screws (Ø4x10L) of the TC sensor cover to remove the sensor cover. 2) Remove TC sensor from the heat exchanger.
