X The PVC pipe must be purchased separately. The transparent part allows you to check drainage. (Fig. 3-6) CAUTION Tighten the hose clamps so their locking nuts face upward. (Fig. 3-6) (2) After checking the drainage, wrap the supplied packing and drain pipe insulator around the pipe. (Fig. 3-7) NOTE Ensure the drain pipe has a downward gradient (1/100 or more) and that there are no water traps. CAUTION G Do not install an air bleeder tube, as this may cause water to spray from the drain tube outlet. (Fig. 3-8) G If it is necessary to increase the height of the drain pipe, the section directly after the connection port can be raised a maximum of 19-11/16 in. Do not raise it any higher than 19-11/16 in., as this could result in water leaks. (Fig. 3-9) G Do not install the pipe with an upward gradient from the connection port. This will cause drain water to flow backwards and leak when the unit is stopped. (Fig. 3-10) G Do not apply force to the piping on the unit side when connecting the drain pipe. The pipe should not be allowed to hang unsupported from its connection to the unit. Fasten the pipe to a wall, frame, or other support as close to the unit as possible. (Fig. 3-11) G Provide insulation for any drain pipe that is run indoors.
