Indoor unit
Insulation cover pipe
Insulation pipe
Be sure to overlap the insulation.
CAUTION
• Be sure to wrap insulation tightly without any gaps.
3 Finish wrapping insulating tape around the rest of the
pipes leading to the outdoor unit.
4 The pipes and electrical cables connecting the indoor
unit with the outdoor unit must be fixed to the wall
with suitable ducts.
CAUTION
• Make sure that all refrigerant connection must be
accessible for easy maintenance and detachment.
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.
High humidity locations such as shorelines, hot springs, lake or riversides, and ridges (when part of the building is covered by
earth and sand)
Restaurant ceiling, sauna, swimming pool etc.
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.
