7. DRAIN PIPING WORK
(1) Drain piping work
Install drain piping so that wastewater drains reliably.
•
Use a pipe diameter that is the same as or greater than the connection pipe (PVC pipe, nominal diam-
eter of 20 mm, outside diameter of 26 mm).
•
Use a short length of pipe and route it at a downward slope of 1/100 or greater such that air does not
collect in the pipe. (
Refer to Fig. 4 and 5.
)
•
If unable to provide an adequate slope for the drain, use the drain up kit (sold separately).
<Example problem>
If water accumulates in the drain pipe, it may cause the drain to become clogged.
