6.1.3. Installing drain pipe
Note: Install the drain pipe.
x
Install the drain pipe with downward gradient (1/50 to
1/100) and so there are no rises or traps in the pipe.
x
Use general hard polyvinyl chloride pipe [3/4 in. (O.D.
1-1/16 in)] and connect it with adhesive (polyvinyl chlo-
ride) so that there is no leakage.
x
When the pipe is long, install supporter.
x
Do not perform air bleeding.
x
Always heat insulate indoor section of drain pipe.
x
When desiring a high drain pipe height, raise it up to 700 mm
(27-9/16 in.) or less from the ceiling within a range of 300 mm
(11-13/16 in.) from the body. A rise dimension over this range
will cause leakage. See  gure on next page.
x
Set up the entire piping lines at the position 100 mm
(3-15/16 in.) lower than the main body drain port, and use
the piping lines O.D. 33 mm (1-5/16 in.) or more with the
descending inclination to 1/100 or more.
