IMPORTANT DETAILS ABOUT THIS LIFT MODEL: This Lift Model is for use in an inverted orientation (e.g.
Cables Motor Cable – Black cable with white, six-pin plugs. Use this cable to connect the Lift Column to the Control Box (using port #1 on the Control Box). Six feet long. Power Cable – Connects Control Box to power outlet. Three feet long. RF Cable (only present if you ordered the RF version of the Lift System) – Use to connect the RF Receiver to the Control Box. Ends have telephone-style connectors. One foot long.
SAFETY INFORMATION SEVERE PERSONAL INJURY AND PROPERTY DAMAGE CAN RESULT FROM IMPROPER INSTALLATION OR ASSEMBLY. READ THE FOLLOWING WARNINGS BEFORE BEGINNING: ENCLOSURE LID HAZARD TV HAZARD CAUTION: Avoid contact with the TV and Lift System during operation. Use with caution. CAUTION: The enclosure lid must be installed as described in the instructions, using the Lid Stabilization hardware. Installing the lid in any other fashion will create hazardous pinch points that can cause serious personal injury.
Types of Controls for Nexus 21 Lift Systems All Nexus 21 Lift Systems come standard with a wireless remote control and receiver. We offer a choice of two different type of remotes: IR and RF (both of which are explained in detail below). Our standard control type is RF, so unless you specifically requested the IR version when you made your purchase, you probably received the RF controls with this Lift System.
About the Cabinet Lid Cover NOTE: The Lid Cover is not provided with the Lift System, as it is part of your cabinetry What is the Lid Cover? The Lid Cover is the piece of material that you choose to have “float” just below the TV. Typically, this material is made of wood and is not provided with the lift system. When the TV lift fully retracts, the Lid Cover will conceal the hole that is required for the system to drop-down through the cabinet and into view. IMPORTANT NOTE: THE LID COVER IS OPTIONAL.
Assembly and Mounting Instructions – DETAILED STEPS Preparing the Enclosure Box BEFORE BEGINNING, PLEASE READ THE SAFETY NOTICE ON THE FIRST PAGE OF THIS DOCUMENT The Enclosure Box for the TV and Lift System should be constructed of materials no less than ¾” thick. We recommend a high-grade plywood or combi-core material. The back and top of the enclosure are the parts that must be able to support the weight of the lift and TV, so particle board materials are not suitable for use in this project.
Assembly and Mounting Instructions – You Are Ready to Start Please perform the following steps, in order: Step 1: Inventory the Parts List. Carefully inspect all items, making sure you have everything shown in the Parts List. Step 2: Seat the “pigtail” cable properly on the top of the Lift Column. Take the Lift Column (Part #1) and find the end with the short black cable (this cable is called the “pigtail”). This end will become the BOTTOM of the Lift Column.
Step 3b: Lightly tap the right and left side of the Bayonet Bracket with a rubber mallet to properly seat the bracket. Turn the Lift Column around and check to make sure the Bayonet Bracket is level. Step 4: Place the Base Mount (Part #2) inside of your enclosure against the back wall and the top panel of the enclosure. Make sure to center the Base Mount from left to right inside the enclosure. Mark the four countersunk holes of the Base Mount.
Step 6: Attach the Lift Column to the Base Mount. Place the Lift Column (Part #1) with the Bayonet Bracket (Part #3) attached against the back wall of the enclosure. Using the provided small 4mm Allen Wrench drive the (4) 6mm x 40mm FHMS Screws into the top of the lift column. NOTE: The end of the Lift Column with the “pig-tail” is the bottom of the Lift Column. Step 7: Using a level, make sure the Lift Column is level and parallel with side panels of the enclosure.
Step 9a: Attach the Screen Back Plate (Part #6) to the Screen Support Bracket (Part #4). Using (4) 3/8-16 x ¾” BHMS attached the Screen Back Plate to center of the Screen Support Bracket. NOTE: Make sure the bent tabs on the Screen Back Plate are on the top. Step 9b: Place two Wire Clips to the inside wall of the Screen Support Bracket. Place one Wire Clip just below the upper set of PEM nuts. Place the second Wire Clip towards the top of the Screen Support Bracket.
Step 11: Attach the Top Support Brackets (Part #9) to the Screen Support Bracket (Part #4) . Using (6) 6mm x 12mm BHMS (3 screws per side) fasten the Top Support Brackets, so the bottom of the Top Support Brackets are a ½” above the opening at the bottom of the enclosure. Step 12: Attach the Lid Plate (Part #5) to the Top Support Brackets (Part #9). Using (4) 6mm x 12mm FHMS Screws attach the Lid Plate to the Top Support Brackets.
Step 13: Mounting the Controls to the Back Panel of the Enclosure: Using (2) #10” x 1 ¾” FHWS attach the Control Box and (2) #8” x ¾” FHWS for the IR or RF Receiver (Depending on which Controls you ordered) to the back panel of the enclosure. The RF Receiver or IR Receiver will plug into either RJ45 port on the Control Box. The Motor Cable must plug in to Port # 1 on the Control Box.
IF YOU HAVE IR CONTROLS, USE THIS DIAGRAM (for RF Controls, see the following page) Once you have connected the controls, test the Lift Column as follows: First, you need to “initialize” the Lift System. If you have already lowered the Lift Column, raise it again, since this step must be performed in the “up” or retracted position. Find the Wired Backup Switch, which has two triangle-shaped buttons - a DOWN (with raised dot) and an UP. Press the UP button and HOLD IT for approximately 5 seconds.

Installing the Lid Stabilization Assembly The two Lid Stabilization Assemblies (each consisting of parts #21 - 25) are used to hold the Ceiling Cover Cut-out in proper alignment with ceiling opening. The assemblies are spring loaded so the Ceiling Cut-out will stop level with the ceiling allowing the Lift to travel an additional 1/8 ”– 1/2” up into the ceiling.
Step 14a: Hold your lid piece (your ceiling cut-out piece) up to the Lid Plate (part #5), which you have already installed on the lift. The Lid Plate has 2 holes that are used to attach your lid piece. Mark the position of the holes on your lid piece. Drill two holes ½” deep using a 3/8” drill bit in the marked positions. Step 14b: Using a flat head screw driver, drive the Brass Inserts (Part #25) into the ½” deep holes.
Step 15b: Place the lid material against the bottom side of the Lid Plate; slide the Threaded Studs through the two holes on the Lid Plate. Slide (2) Lid Stabilization Springs (Part #24) over the Threaded Studs. Step 15c: Add a 1” Fender Washer to the Threaded Studs on top of the spring you previously installed. Once washer is added, fasten a 10-32 Nut (Part #22) to the top of the Threaded Studs. You will need to compress the spring in order to screw the nuts down.
Mounting the TV to the Lift A Flat/Unobstructed Back Diagram “A” installation procedure: 1) Place the flat screen TV face down on a protected surface. 2) Position the Vertical Mounting Bars equidistant from the bottom and top of the TV, with the slots facing toward the top of the TV. 3) Using the four (4) Square Multi-Mount washers and the TV mounting screws selected from the bag, attach and tighten the hardware. DO NOT OVERTIGTHEN HARDWARE. DAMAGE TO TV MAY RESULT.
Step 16: Attach the Vertical Mounting Bars to the TV. Before you begin, hand thread screws found in bag labeled “TV Mounting Screws/Spacers” into the threaded inserts on the back of your TV to determine the correct screw diameter (M6 or M8). The length of the screw required will depend on whether the TV has a flat/unobstructed or irregular/obstructed back. Follow diagram “A” for TV’s with flat/unobstructed back. Use diagram “B” for TV’s with irregular/ obstructed back.

Supplemental Page B: Setting a Height Limit Please follow this procedure if you would like to limit the distance that your TV Lift extends. To set your Travel Limit with IR Controls: If you want the lift system to always go to its full extension, do NOT use the Height Limit Insert. Simply leave it unplugged and the system will always travel to the full extension. To limit the travel, follow the procedure below: 1.
