• 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.
Step 10 Installing the drain hose and
drain pipe
1 Push the supplied drain hose as far as possible over
the drain socket.
2 Tighten the metal clamp as shown in the picture.
3 Wrap the supplied large sealing pad over the metal
clamp and drain hose to insulate and fix it with clamps.
4 Insulate the complete drain piping inside the building
(field supply).
If the drain hose cannot be sufficiently set on a slope,
fit the hose with drain raising piping (field supply).
5 Push the drain hose up to insulation when connecting
the drain hose to drain socket.
