11. Installation
• 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.
6 Push the drain hose up to insulation when
connecting the drain hose to drain socket.
• If it is necessary to increase the height of the drain
pipe, install the drain pipe straight within 300 mm
from the drain hose port. If it is raised higher than
550 mm, there may be water leaks.
