Mechanical Installation

2-2

Before beginning the installation process, verify the following:

•

The mounting structure will provide a straight and square-mounting frame
for the display.

•

The mounting structure is capable of supporting the display and will not
yield at any unsupported points after mounting.

•

Clearance: 3" of unobstructed space is available below the display for filter
removal from the display. 1-¼" of unobstructed space is available above the
top of the display to remove the eyebolt and plug the hole properly.

Correct any deficiencies before installation.

2.3 Ventilation

Requirements

Reference Drawing:

Shop Drawing, AF-3155-**x***-20mm-RGB................

Drawing B-184075

Fans are mounted in the bottom of the display for ventilation. Maintain a minimum
distance of 3" (7.62cm) below the display to maintain proper airflow. Refer to the

Drawing

B-184075

for additional information.

If the display cabinet is completely enclosed:

•

12 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.

•

250 cubic feet per minute of fresh air exchange per fan must be provided by
means of forced ventilation when cabinet is mounted in an enclosed
structure.

If these requirements are not met, the Galaxy

®

display warranty may be void.
