Caution
In cold regions, always drain the water as a measure to prevent freezing. Failure to follow this
instruction may cause water leakage.
To use the basin for a long period of time, clean the strainer (inside the check valve) regularly.
If temperatures are expected to drop below freezing in cold regions, drain the water from the check valve.

Prepare a container for the water.
Detach the maintenance cover.
The cover can be detached by pulling horizontally, while
gently pressing the cover sides.
Drain the water from the stink trap and clean the trap.
To drain the water into the container, rotate and detach
the drain nut of the stink trap. After draining the water
and cleaning the trap by removing dust and dirt, tighten
the drain nut firmly.
Warning
The hot water supply pipe may become
very hot. Take care not to touch the pipe
directly.

After removing the maintenance cover, check that
there is no water leakage within the basin. If there
is water leakage, the pipes within the basin may be
damaged.
If this is the case, contact your closest dealer.
Leaving water leaks may sometimes result in
serious accidents or water damage. In this case,
the customer will be responsible for the accident
and a significant amount of labor and costs will be
incurred.
Before and after using the product, check that water does not trickle out beneath the main unit.
Check that water does not leak from the water supply pipe, hot-water supply pipe, and the joints of the
drainage pipe. Be sure to inspect for water leaks and clean on a regular basis.
(We recommend checking for water leaks at least once a month by opening the maintenance cover.)
