2.3 Ventilation Requirements
Reference Drawing:
Shop Drawing, Mounting Details ................................. Drawing B-227417
Vents are provided in the face of the display for ventilation. Vents and fans draw air
into the front of the display at the bottom, and the warm air is expelled out the top of
the display through vents in the front. Both the intake and exhaust vents run the
length of the display and should not be obstructed. Refer to Shop Drawing B-
227417 for additional information.
The display cabinet may be completely enclosed on the sides and in back, only if the
vents in the face are not obstructed. In some displays there will be a hood on the
backsheet, and the back of the display cannot be covered.
If these requirements are not met, the Galaxy
®
display warranty may be void.
2.4 Lifting the Display
The top of the display 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 7 illustrates both the correct (left example) and the incorrect (right example)
method of lifting a display. Lift the display with the lifting bar as shown on the left.
Use every lifting point provided.
Figure 7: Lifting the Display (Correct, Left; Incorrect, Right)
Do not attempt to permanently support the display by the eyebolts.
Eyebolts can be removed from the display to eliminate the need for overhead
clearance.
