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 types 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.
Assembly and Mounting – Things to Think About First SAFETY NOTICE: - For proper support, the Lift System MUST NOT be attached to any material that is less than ¾” thick. This applies to BOTH the back and bottom mounting points. - The Lift Column is ONLY designed and rated for VERTICAL, NON-INVERTED USE. DO NOT MOUNT THIS LIFT SYSTEM UPSIDE DOWN or SIDEWAYS (HORIZONTALLY)! TIP: Inverted (drop-down) lift systems are available from Nexus 21. Contact Customer Service at (866) 500-5438.
Table of Contents The entire Lift System consists of three major systems, the Actuation System, Cable Management System and the TV Mounting System. This instruction manual will cover how to build, install and connect the Lift.

Assembling the Actuation System For these steps you will need the following parts: Lower Actuation Assembly with Lower Support Bracket already installed in the Cabinet. Upper Actuation Assembly (8) 6 x 20 mm FHMS Screws Small Hex Key 16 Step 16: Place the Upper Actuation Assembly onto the Lower Actuation Assembly. You may need to support the Upper Actuation Assembly until you fasten it to the Lower Actuation Assembly. See photo to the right for reference.
Assembling the Cable Management System For these steps you will need the following parts: Long Cable Management Track Short Cable Management Track Screen Support Actuation System (8) 5 x 12 mm FHMS Screws 4.5m Motor Cable (4) 6 x 16 mm FHMS Screws Small Hex Key 3 mm Hex Key 2 Wire Clips 19 Step 19: Place 1 wire clip on the inner slotted wall of the Screen Support so that it is horizontally aligned with the 1st hole from the top.
Step 21: Feed the 4.5m Motor Cable through the Short Cable Management Track and down through the slot on the Screen Support. See photos below for reference. 21 21 Step 22: Connect the end of the motor cable that was fed through the Screen Support in Step 21 to the Upper Lift Column, then put the motor cable into the wire clips.
24 Step 24: Fasten the loose end of the Short Cable Management Track to the Actuation Assembly using (2) 5 x 12mm FHMS Screws. See photo the left for reference. 25 Step 25: If there is excess cable below the Screen Support remove it by feeding it up into the Short Cable Management Track and pulling it through the other side. Note: Make sure the motor cable is not hanging in front of the Upper Column as this may trigger collision detection when operating the lift.
Step 27: Feed the remaining portion of the 4.5m motor cable through slot on the Upper Actuation Assembly and down into the Long Cable Management Track. See photos to the left and below for reference. 27 27 28 Step 28: Fasten the loose end of the Long Cable Management Track to the Lower Support Bracket Assembly using (2) 5 x 12 mm FHMS Screws. 29 Step 29: The Cable Management System is now attached to the Actuation System.

32 Step 32: Attach both of the Top Plates to the top of the Top Support Brackets using (4) 6 x 12 FHMS Screws. Ensure that wings of the Top Plate are pointing towards the front of the Lift System. See photo to the left for reference. 33 Step 33: The Lift System is now completely assembled.
Connecting the Lift System Step 34: Using the XL-75 IR Wiring Diagram below, connect the cables for your Lift System with IR Controls. Note: If you have RF Controls please see the next page for the L-75 RF Wiring Diagram.
Step 34 Continued: Use this XL-75 RF Wiring Diagram if you have RF Controls. Note: If you have IR Controls refer to the previous page.
******IMPORTANT***** Step 35: Once you have connected the controls, test the Lift Column as follows: 1. First, you need to “initialize” the Lift System. If you have already raised the Lift Column, lower it again, since this step must be performed in the “down” position. 2. Find the Wired Backup Switch, which has two triangle-shaped buttons - an UP (with raised dot) and a DOWN. 3. Press the DOWN button and HOLD IT DOWN for approximately 5 seconds. 4. You should see a slight movement in the Lift Column.
Mounting the TV to the Lift Step 36: Attach the Vertical Mounting Bars to the TV using the screws found in the bag labeled “TV Mounting Screws/Spacers.” The length and size of the screw required will depend on whether the TV has a flat/unobstructed or irregular/obstructed back. A Flat/Unobstructed Back Diagram “A” installation procedure: 1) Place the flat screen TV face down on a protected surface.
Step 37: Mount the TV to the front of the lift system by hanging the TV on the Screen Back Plate. DO NOT use the outside slot. 37 37 Step 38: Insert both Screen Locks into both Vertical Mounting Bars. Using (2) Screen Locks, place one Screen Lock on the bottom set of hooks for each Vertical Mount Bar. Using a Philips Head Screwdriver (not provided), tighten the Screen Locks against the bottom of the Screen Back Plate.
Attaching the Floating Lid Step 39: Fully retract the lift and place the Cabinet Lid onto the Top Plates so that it is centered in the cabinet opening. Step 40: Run the Lift up using the IR or RF Controls and then back down. Make sure that when the lift comes down, the Cabinet Lid drops into a centered position within the cabinet opening. NOTE: You may temporarily tape your lid in place to prevent any shifting if needed.
Installing the Tapered Pins in the Floating Lid What Are the Tapered Pins, and Why Use Them? The two 1½” x ¼” Steel Threaded Tapered Pins are used IN PLACE OF SCREWS to hold your cabinet top (lid) in place on the Lift System Top Plate (Part #8). The Tapered Pins will keep your lid firmly in place, but will also allow it to separate from the lift system if anything (like a finger) gets in the way when the TV lowers. See Safety Notice above. Please do NOT use screws with your cabinet lid.
How to Properly Install a Lid “Catch” with a Nexus 21 Lift System There are multiple ways to properly create a “catch” for the lid to rest on, when the lift is in the fully retracted position. Down below are a few examples. Using the provided Lid Catch Brackets with (8) #10 x ¾” THWS attach the brackets to each corner of the lid opening.
Adjustments The Top Support Brackets bolt to the back of the Screen Back Plate and have slotted holes that allow you to adjust the installation height of the Lift in ¼” increments. Note: You must use all four bolt holes on the Screen Back Plate when adjusting the Top Support Brackets. You can move the Screen Back Plate up and down, along the Screen Support to raise and lower the position of the TV on the lift. See photo to the left for reference.
Reference Guide Lift Components: Control Box Motor Cable Wired Backup Switch Height Limit Insert IR Receiver RF Receiver Interface Cable Setting your Height Limit Setting the Height Limit for IR and RF: 1. Simply extend the lift to your desired height using IR Receiver or Wired Backup Switch and tap the down button to stop the lift at that height. 2. Then put the Height Limit Insert into either port A1 or A2 on the Control Box. 3. Your remote will now obey the height limit you have set.
