“Weight, Size, and Vertical Travel” on page 3 for weight
limitations.
2. Determine vertical travel height required for presentation
viewing. See Table 1 for height limitations.
Furniture Opening Finish Piece Options
Because of the wide variety of possible mounting situations, Chief Manufacturing can only provide general guidelines for finish options. Study the following
information carefully, and adapt it as necessary to fit
your specific installation.
NOTE: Always leave access to the lift for maintenance purposes.
Extended Position Finish Piece Option
A finish piece, covering the opening when the unit is
in the fully extended position, may be installed for
estetic purposes. Using the material cut slight smaller
than the opening size, install the finish piece as follows:
1. Measure the width of the finish piece.
2. Measure the distance between the verticle extrusion arms and
subtract a nominal amount for clearance.
CAUTION: Failure to allow clearance for the finish piece to
retract to the fully lowered position may result in damage to the finish piece, damage to the lift, and damage to the plasma.
6
Instruction Manual Plasma Display Electric Pop-Up Lift
3. Make sure the finish piece measured in step 1 is smaller than
the clearance distance measured in step 2 and note any cord
management access holes that may be necessary.
4. Measure the thickness of the finish piece, add this thickness to
the length of the five capscrews used to secure the plasma
mounting assembly when a backing is not used, and obtain the
five longer 3/8-16 capscrews for assembly with backing.
5. Place the finish piece on the shelf, making sure it is correctly
positioned to allow clearance when lowered, and transfer the
pattern of the five access holes onto the finish piece.
Plasma Mounting

Shelf
6. Drill five through holes, with clearance for 3/8” bolts, in the
finish piece and any cord management holes that may be necessary.
7. Place the finish piece on the shelf.
8. Place the plasma mounting assembly on top of the finish piece
(see Figure 5).
9. Using a 5/16” Allen wrench inserted through the five access
holes on the bottom of the shelf (see Figure 6), install five
longer 3/8-16 cap screws.
10. With the aid of another person, lift the display up to the mount,
aligning the PSB mounting buttons on the display with the
teardrop slots on the mount, set the plasma into place and
adjust mounting assembly to ensure proper clearance is
achieved.
11. Measure and record clearance dimensions and, with the aid of
another person, remove plasma.
WARNNG: Be aware during the installation that this is a motorized device, and
there are pinch points for people and for
electrical wiring. Keep hands and electrical wiring away from internal components
of the mechanism
12. Carefully, without plasma mounted on lift, operate lift to
ensure finish piece has sufficient clearance during full travel.
Retracted Position Finish Piece Option
A finish piece, covering the opening when the unit is
retracted, may be installed for estetic purposes. Install
the finish piece as follows:
