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 player with 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.

Unit

Inlet and outlet types

Ventilation opening ratio 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.
