Fans are mounted in the bottom of the display and to the back sheet for ventilation. Maintain a
minimum distance of 3" (7.62cm) below the display to maintain proper airflow. Refer to the
appropriate shop drawing for additional information.
If the display cabinet is completely enclosed:
 6 square inches of unobstructed opening per module must be provided to ensure adequate
cooling.
 Allowances must be made to compensate for the percentage of material covering the openings
in the structure.
 For adequate cooling, forced ventilation may be required. If air is forced into the enclosed
cabinet, 10 cubic feet per minute must be provided per module (10.6" x 10.6" active area).
If these requirements are not met, the Galaxy display warranty may be void.
2.4 Lifting the Display
The top of the larger displays is equipped with eyebolts that are used to lift the unit. Take special care
to ensure that the rated load of the eyebolts is not exceeded. Refer to the information at the end of this
section labeled Eyebolts to determine the allowable load of the eyebolts shipped with the display.
Figure 6 below illustrates both the correct (left example) and the incorrect (right example) method of
lifting a display. Lift the display as shown on the left, with the lifting bar. Use every lifting point
provided.
Do not attempt to permanently support the display by the eyebolts.
If removing the eyebolts, adequately seal the holes using 13 bolts and sealing washers, ½ inch in size.
Silicone along the threads to ensure that water does not enter the display.
