INSTALLATION

Preinstallation

IMPORTANT ! : Reference the LED screen installation manual for specific instructions regarding care, handling, cabling and installation of the LED screens.

Chief DVM27U4 - Preinstallation - 1

CAUTION: Handle the LED screens with care, being careful to not impact or drop the LED screen.

Chief DVM27U4 - Preinstallation - 2

CAUTION: There is a magnetic surface on the front of the LED screen. To prevent damage ensure that no metallic object is pulled onto the LED screen.

NOTE: When planning the installation, remember the requirement to run power and signal to the video wall.

Site Assessment

Before beginning any installation the site should be assessed in several areas to help avoid any issues during the actual installation.

  • Wall Structure - It is recommended that a 3/4" furniture-grade plywood-backed wall be used in most LED video walls. The use of a wood stud wall is not appropriate since the studs won't be in the proper location for an LED video wall.
  • Wall High/Low Points - Locate any high or low points on the wall that may cause problems, and try to set up install so that these points can be avoided, if possible.
  • Flatness/Plumb of Wall - Learn how much depth adjustment will be needed across the LED video wall mounting area.
  • Power/Cable - Locate all power outlets and cable access holes that need to be cleared by the installation. Plan appropriately for those holes.
  • Installing in a Recess - Verify the level and squareness of the recessed area. Since these areas are rarely perfect you may need to decide what to use as a reference point.

  • The recess top or bottom may not be level so the video wall may need to be installed to align with the recess, rather than being level with the wall.

  • If the recess is not square the sides may make the recess look crooked. If possible, the recess should be fixed. If repairing the recess isn't an option it may be best to "split the difference" between the recess sides to make the video wa appear level.

- Where to Begin the Video Wall - The installer should make the decision whether the video wall will be started at the top, bottom, left, right or center.

  • If a lower bottom reference is given in the specifications, it may make sense to start at the bottom of the video wall to ensure that this specification is met from the start of installation.
  • If building inside of a recess, it may be easier to start in the center of the space since the video wall will most likely need to be centered within the recess.

- Extender mounts - If creating a video wall with more than a single row, you will be using the extender mounts (DVM27U2E/DVM27U3E/DVM27U4E) in addition to the starter mounts (DVM27U2/DVM27U3/DVM27U4).

- Measurement Worksheets - In order to determine mounting hole locations, refer to measurement worksheets on pages 8-10. It may be helpful to print the appropriate sheet and fill in the measurements of the display in the blanks to have as reference for making the proper calculations. (See Figure 1)

Chief DVM27U4 - Site Assessment - 2

Just a tip - For larger LED walls it is helpful to check placement and alignment of the mounts by putting a few cabinets without the LED's in place in the bottom row of the installed mounts (referencing the LED screen installation manual for specific instructions) during the mount installation, verifying that everything is staying aligned and level, and then continuing the mount installation.

Installation of First Row of Uprights

NOTE: The mount should be installed from bottom to top, installing the entire bottom row first before building up as needed.

NOTE: Refer to dimensions drawings on pages 5-10 for further details on installation locations. Corresponding measurement worksheet may be printed and filled out for quick reference as measurements are made.

  1. Determine mounting locations for first set of uprights using formulas found on measurement worksheets (pages 8-10).

a. Horizontally

  • Odd number of columns: From centerline to middle column = (MPW/2) - 2.875" (73mm).
  • Even number of columns: From seam or edge of display = [(DW-MPW/2)] + 2.875" (73mm).
    b. Vertically
    • 2-High

  • Display edge to bottom mounting point = [1(DH) - 10.28" (261.1mm)].

  • Display edge to top mounting point = [1(DH) - 10.28" (261.1mm)] + 20.57 (522.5mm).

• 3-High

  • Display edge to bottom mounting point = [1.5(DH) - 16.93" (430mm)].
  • Display edge to top mounting point = [1.5)DH) - 16.93" (430mm)] + 33.86 (860mm).

• 4-High

  • Display edge to bottom mounting point = [2(DH) - 23.57" (598.7mm)].
  • Display edge to top mounting point = [2(DH) - 23.57" (598.7mm)] + 47.14" (1197.5mm).

  • Draw level horizontal lines at vertical locations determined in Step 2b using a 4-foot level or a laser level. (See Figure 2)

IMPORTANT ! : Make sure to include the above finished floor measurement (AFF) in the calculation to determine mounting locations.

The DVM27U wall mounts are designed to be mounted to the following wall types:

Figure 11

  1. Use a tape measure to determine coverage height (CH), which is the distance from the top of display to the top of mounting column. (See Figure 11)
  2. Compare the coverage height (CH) with remaining display height to determine whether column height needs to be adjusted.

  3. 2 high: If CH is less than DH, adjust by the difference.

  4. 3 high: If CH is less than 2 × DH , adjust by the difference.
  5. 4 high: If CH is less than 3 × DH , adjust be the difference.
  6. If CH is greater than the formulas listed above, no adjustment is needed.

Sample Calculation

- Mount size 3 high

• Coverage height (CH) = 26.85" (682.0mm)
• Display height (DH) = 13.29" (337.5mm)
- 2 × DH = 26.57'' (675.0) which is less than CH
- Minimum height adjustment for coverage = 26.85" (682.0mm) - 26.57" (675.0mm) = 0.280" (7.0mm).

Plumb Leveling

  1. After the bottom row has been installed and leveled, adjust the outermost uprights away from the wall 1/4" (approximately four full turns) prior to plumbing middle uprights. Uprights should be adjusted to a point that the mount rail extends past the planar face of all the middle uprights. Depth adjustment is controlled by depth adjustment screws on each upright. (See Figure 14)

Fastener Installation Methods

IMPORTANT! : See Table 1 for appropriate hardware and pilot hole sizes for various wall types.

IMPORTANT ! : The expanse of the LED wall will most likely mean that attachment of the wall mounts will not all be in studs. The attachment method will most likely vary throughout the installation, and more than one of the various methods outlined here will most likely be used.

Wood Stud/Steel Stud (w/plywood backing)

IMPORTANT ! : The DVM72U LED wall mounts are designed to be mounted to a 3/4" thickness plywood-backed, 2" x 4" wood studs (16" on center minimum) wall with a maximum drywall thickness of 5/8" or a 3/4" thickness plywood-backed, steel stud wall covered with drywall having a maximum thickness of 5/8".

  1. Use one 5/16" x 2-1/2" hex flange head lag bolt (CA) and 5/16" washer (CE) through product and into pilot hole. (See Figure 31)
  2. Repeat for remaining pilot holes.

(CA) (CE)
