Before Performing the Installation Drain Piping(1) Limitations of Raising the Drain Pipe ConnectionCAUTION● The drain pipe can be raised to a maximum height of2.79 ft. (850 mm) from the bottom surface of the ceiling.Do not attempt to raise it higher than 2.79 ft. (850 mm).Doing so will result in water leakage. (Fig. 3-6)(2) Limitations of Drain Pipe ConnectionCAUTION● Do not install the drain pipe with an upward gradient from thedrain port connection. This will cause the drain water to flowbackward and leak when the unit is not operating. (Fig. 3-7)● Do not install an air bleeder as this may cause water to sprayfrom the drain pipe outlet. (Fig. 3-7)● Do not provide U-trap or bell-shaped trap in the middle of thedrain pipe. Doing so will cause abnormal sound.(Fig. 3-7)● Make sure the drain pipe has a downward gradient (1/100 ormore; downward from drain port connection).(Fig. 3-8)(3) Limitations of Drain Hose ConnectionCAUTION● Do not bend the supplied drain hose 90° or more.Bend it less than 45°. (Fig. 3-9)● Do not make a trap in the middle of the supplied drain hose.Doing so will cause abnormal sound. (Fig. 3-10)
