1 Perform final tightening by tightening the double nut firmly. The product may fall if not installed properly.
2 Using a level, or vinyl hose filled with water, fine adjust so that the body is level.
2. INSTALLING DRAIN PIPE
Install the drain pipe in accordance with the instructions in this installation instruction sheet and keep the area
warm enough to prevent condensation. Problems with the piping may lead to water leaks.
Use general hard polyvinyl chloride pipe (VP25) [outside diam-
eter 32 mm (1-1/4")] and connect it with adhesive (polyvinyl chlo-
ride) so that there is no leakage.
Always heat insulate the indoor side of the drain pipe.
• Do not provide a rise, trap and air bleeding.
• Provide a downward gradient (1/50 to 1/100).
• Provide supports when long pipes are installed.
• When desiring a high drain pipe height, raise it up to 400 mm
(15") or less from the ceiling within a range of 150 mm (6") from
the body. A rise dimension over this range will cause leakage.
