• When installing insulation in the 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.
Step 10 Installing the drain hose and
drain pipe
