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.
࡛
Refrigerant pipe before EEV kit and MCU or without
EEV kit and MCU
ࣞ
You can contact the gas side and liquid side pipes
but the pipes should not be pressed.
ࣞ
When contacting the gas side and liquid side pipe,
use 1 grade thicker insulator.
࡛
Refrigerant pipe after EEV kit and MCU
ࣞ
Install the gas side and liquid side pipes, leave
10mm of space.
ࣞ
When contacting the gas side and liquid side pipe,
use 1 grade thicker insulator.
