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.

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.

Precautions for enclosure unit designing
No additional front glass (tempered glass)
•Applying tempered glass on the front side of the display is prohibited.
•Consider the location of the IR Remote and Eco Sensor on your product when designing an
enclosure unit.
"The sensor may not operate or may cause the screen to darken if the sensor is not
sufficiently exposed.
•If the product temperature increases due to high outside temperature or the environment
in which the product is installed, the luminance decreases for product overheating
mitigation and accident prevention.

Installation requirements
Chapter 02
Surrounding environment
•When installed in places such as a ski resort, fans may not operate if the inlet is blocked by
a pile of snow. Install a cover to avoid snow piling directly onto the inlet
Cover
•The product can be used in a train or subway station.
The outdoor unit is designed to keep out iron dust.

15
•When installed on beach area, make sure the display is placed where seawater is not accessible.
"Ensure the display unit installed location is within safe distance from the possible contact from rising seawater due to strong winds due to storm or other natural phenomenon.

16
Rotation and tilt angle
•The outdoor unit can be installed in Landscape or Portrait orientations.
•The outdoor unit can be installed in a tilted position on a vertical wall or an
obstacle, up to 15°.

Clearance forwall mounting
Installing the outdoor unit only
•When installing close to the wall, maintain a sufficient clearance in order to secure air flow.
•Clearance for OH46F/OH55A/OH55F ( ): 50 mm or more
•Clearance for OH75A/OH75F/OH85F ( )
– Example 1) Exposure to direct sunlight: 200 mm or more
– Example 2) Atmospheric temperatures under 35 ℃ without direct sunlight: 60 mm or
more
•Add partitions between the inlet and outlet to prevent discharged air from flowing back
into the inlet.
"If the unit is subjected to excess heat due to an insufficient gap, this may cause a
malfunction, which will not be covered by the warranty.
•If the distance between the back of the product and the wall is too large, the following
types of partitions can be installed.
