14. Installation
Indoor Unit
5 Select the insulation of the refrigerant pipe.
• Insulate the gas side and liquid side pipe, noting the
insulation thickness that must differ according to the
pipe size.
• Standard: Less than an indoor temperature of 30°C,
with humidity at 85%. If installing in a high humidity
environment, use one grade thicker insulator by
referring to the table below. If installing in an
unfavourable environment, use thicker one.
• The heat-resistance temperature of the insulator must
be more than 120°C.

• 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.
