• When installing insulation in the places and
conditions below, use the same insulation that is
used for high humidity conditions.
<Geological condition>
High humidity locations such as shorelines, hot
springs, lake or riversides, and ridges (when part of
the building is covered by earth and sand)
<Operation purpose condition>
Restaurant ceiling, sauna, swimming pool etc.
<Building construction condition>
Ceilings frequently exposed to moisture and cooling
are not covered. For example, pipes installed at a
corridor of a dormitory and studio or near an exit
that opens and closes frequently.
Places (where the pipes are installed) that are highly
humid due to a lack of ventilation.

If the drain hose cannot be sufficiently set on a slope,
fit the hose with drain raising piping (field supply).
