located below the drain outlet.
* To prevent backflow, do not connect the drain pipe directly to the sewer system.  Keep
more than 5 cm air gap between the pipe end and the sewer.  (Since a U-trap is provided
inside the unit, no external U-trap is required.)* Do not let water drain directly onto the floor before running into the sewer.  Foreign matteron the floor may mix into the water and clog the sewer, or the water could run in a wrong
direction.
* After connections, check them according to “III. 2. [d] WATER SUPPLY AND DRAIN
CONNECTIONS (ANNUAL/BIANNUAL)”.
