Enclosure unit design guide
Chapter 01
Air ow direction
The outdoor unit uses cooling fans to take in outside air to lower the internal temperature and discharge the hot air.
"When installing an outdoor unit, remove any obstacles near the air inlet and outlet that may affect air flow.

Enclosure unit partition design
Partition design guide
•For outdoor units, add partitions between the inlet and outlet inside the enclosure unit to keep air paths separated.
•Partitions should fit perfectly inside the enclosure unit, with no gap between the outdoor unit and enclosure unit. If there is a gap, use a foam tape to fill it.

Partitions when installing with an optional media player
To install an optional media playerwith the outdoor unit, use partitions to isolate the player.
"There should be no gap between the media player and outdoor unit; only allow cables through the partition.
"The optional media player is an additional source of heat and the increased temperature inside the enclosure unit may cause the outdoor unit to malfunction; a malfunction occurring in this
manner will not be covered by the warranty.

Inlet and outlet types
The opening size for air inlet and outlet should be minimum 50%.
Air inlet and outlet should be grid or mesh types.
"Do not use the louver type as it has a limited intake size.

Opening size and ratio
Follow the guide when combining the outdoor unit with the enclosure unit.
"If the instructions provided in this guide are not observed, the cooling system may not work
properly and may cause a malfunction, which will not be covered by warranty.
"Calculating the opening size and ratio
Total opening size: 181 x 89 = 16109 mm⁲
