Assembly And Installation

CAUTION: Attachment holes may be damaged if a power drill is used to insert button head cap screws. Screws should first be inserted and turned BY HAND with the hex key or with a hand-held screwdriver BEFORE using the hex head drill bit and power drill to complete the attachment.

Cart Assembly

1. Carefully set column assembly (F) on its left side. (See Figure 1)
2. Place right transition cover (M) on right cart leg (J), lining up the holes on the cover with the holes on the leg and column assembly base. (See Figure 1)
3. Use two 5/16-18 x 3 3/4” button head cap screws (P) to secure leg (J) and cover (M) to column assembly (F). (See Figure 1) Figure 1
4. Turn column assembly (F) onto its right side. (See Figure 2) Figure 2
5. Place left transition cover (L) on left cart leg (H), lining up the holes on the cover with the holes on the leg and column assembly base. (See Figure 2)
6. Use two 5/16-18 x 3 3/4” button head cap screws (P) to secure leg (H) and cover (L) to column assembly (F). (See Figure 2)
7. Slide interface head assembly (E) into column assembly (F). (See Figure 3)
8. Use four 5/16-18 x 3/4” button head cap screws (N) to secure interface head assembly (E) to column assembly(F). (See Figure 3) Figure 3
9. Use remaining 5/16-18 x 3/4” button head cap screw (N) to secure column upper cover (C) to interface head assembly (E). (See Figure 4)
10. Snap column inner cover (D) onto column assembly (F). (See Figure 4) Figure 4

Display Installation

WARNING: Exceeding the weight capacity can result in serious personal injury or damage to the equipment! It is the installer’s responsibility to make sure the combined weight of all components attached to the MPAU up to (and including) the display does not exceed 125 lbs (56.7 kg). Use with heavier televisions may result in instability causing tip over resulting in death or serious injury!

1. Lay display face down on the protective surface.
   CAUTION: Using screws of improper diameter may damage your display! Proper screws will easily thread into display mounting holes.

2. Select screw diameter by examining hardware (TA-TL) (4mm, 5mm, 6mm, or 8mm) and comparing with mounting holes on display. (See Figure 6)

3. Select spacers: (See Figure 6)
   • If mounting holes are not recessed and both uprights (B) can lay flat against the display, then no spacers are required.
   • If mounting holes are recessed, or if protrusions prevent uprights (B) from laying flat, then spacers (TM) must be used.
   CAUTION: Using screws of improper length may damage your display! Proper screws will have adequate thread engagement without contacting the bottom of display mounting holes.

4. Select screw length: (See Figure 6)
   • Using your hand, insert SHORTEST length screw of selected diameter (TA, TD, TG, or TJ) through universal washer (TN), uprights (B), nesting spacer (TM), into display mounting hole. Do NOT thread screw into the hole at this time. Figure 6
   NOTE: Universal washers (TN) are not needed if using M8 button head cap screws (TJ, TK, or TL).
   • Proper screw length requires the base of the screw head to protrude above the flat washer at a distance equal to or greater than the screw diameter. If screw length is inadequate, select a longer screw. Select the shortest screw which will protrude the required distance.

5. Place uprights (B) on display, ensuring: (See Figure 6)
   • Center of uprights (B) are as close to the center of the back of the display as possible after being installed. The Center of the bracket is indicated by the diamond-shaped hole.

6. Use selected screws and spacers to install two interface uprights (B) to the back of the display. (See Figure 6)
   IMPORTANT !: The M8 screws do NOT require a washer. Use the universal washer (TN) only with M4, M5, and M6 screws.
   NOTE: The nesting spacers (TM) may be used separately, or put two together in different configurations to create different size spacers. (See Figure 5) Figure 5

Figure 6

WARNING: Display may be very heavy! Ensure display may be safely lifted and maneuvered as required to install on the cart. Failure to take adequate precautions can result in serious personal injury or damage to the equipment!

1. Position latches on interface uprights so that they are in the “open” position. (See Figure 7)

2. Hang interface uprights (B) on interface head assembly (E). (See Figure 7) Figure 7
   IMPORTANT!: In order to ensure an even mount, install uprights to be centered over column assembly. Do NOT install both uprights to the same side of column assembly! (See Figure 8) Figure 8

3. Move latches on interface uprights to the “closed” position to secure display to head assembly. (See Figure 9) Figure 9

4. Snap four upright covers (A) onto uprights. (See Figure 10)
   NOTE: Tabs on the inside of covers (A) will snap directly into holes on uprights to ensure a secure connection. Figure 10

5. (Optional) Use padlocks (not provided) to secure uprights to head assembly. (See Figure 10)

Cable Management

NOTE: The following cable management options may vary based on the type of display being mounted and the user preference.

1. Use two 1/4-20 x 1/2” Phillips pan machine screws (Q) to attach two cable hooks (K) to the bottom of column assembly (F). (See Figure 11) Figure 11
2. Place FCA clip (U) into a groove on the back of the Fusion mount with the clip handle in a vertical position. (See Figure 12) Figure 12
3. Rotate FCA clip (U) 90° in either direction until the clip handle is in a horizontal position. (See Figure 12)
4. Repeat Steps 1-2 for all clips to be installed.
5. Route cables along FCA clips to be used for cable management. (See Figure 13) Figure 13
6. Use cable ties (V) to secure cables to FCA clips. (See Figure 13)
7. Route cables from the display through the front channel of column assembly. (See Figure 14) Figure 14
8. Route cables down column channel, tucking them behind the height-adjustment carriage and underneath bracket holding height-adjustment shaft. (See Figure 15)
9. Wrap cables around cable hooks as desired. (See Figure15)
10. Snapback cover (G) onto the back of column assembly making sure cables fit through opening at bottom of the cover. (See Figure 15) Figure 15

Cart Use and Maintenance

WARNING: Exceeding the weight capacity can result in serious personal injury or damage to the equipment! It is the installer’s responsibility to make sure the combined weight of all components located between the MPAU up to (and including) the display does not exceed 125 lbs (56.7 kg).
WARNING: RISK OF SERIOUS INJURY OR DEATH! Placing a remote control or toy on the cart may encourage a child to climb onto the cart causing the cart to tip over onto the child. DO NOT place remote controls or toys on the cart!
WARNING: RISK OF SERIOUS INJURY OR DEATH! Relocating audio and/or video equipment to the cart may result in the cart collapsing or overturning onto a child. DO NOT relocate audio and/or video equipment to the cart!
WARNING: CART CAN TIP OVER RESULTING IN INJURY! Do not allow children under 16 to move carts. Only adults should move this cart. Move the cart slowly. Apply moving force on narrow dimensions. Never apply force at the top – always push toward the middle. Push, don’t pull the cart. (See Figure 19)

NOTE: The MPAU cart has no user-serviceable parts.
NOTE: The MPAU cart can support screen sizes up to a maximum of 70″ wide.

1. Always place the cart on a level surface. Figure 19
2. Always lock the wheels when the cart is not moving.
3. Check and tighten the hex nuts on the casters occasionally. (See Figure 20) These should be checked especially after use on uneven ground.

Removing Display from Cart

1. Remove any padlocks from interface uprights if installed.

2. Position latches on interface uprights so that they are in the “open” position. (See Figure 21)
   WARNING: DISPLAYS MAY WEIGHT IN EXCESS OF 40 LBS! Always use two people and proper lifting techniques when installing or positioning the display on the cart.
