SAFETY INFORMATION
SEVERE PERSONAL INJURY AND PROPERTY DAMAGE CAN RESULT FROM IMPROPER INSTALLATION OR ASSEMBLY.
READ THE FOLLOWING WARNINGS BEFORE BEGINNING:
WARNINGS:
1. Do not use this product for any application other than those specified by Nexus 21.
2. Do not exceed the weight capacity. This can result in serious personal injury or damage to the equipment. It is the installer’s
responsibility to ensure that the total combined weight of all attached components does not exceed that of the maximum figure stated.
3. Follow all technical specifications and instructions during the installation.
4. Only use attachments/accessories specified by the manufacturer.
5. Close supervision is necessary when this system is being used by, or near, children, or disabled persons.
6. It is the responsibility of the installer to warn all potential users of the dangers of interfering with the mechanism during operation.
7. Read all technical instructions fully before installation and use. It is the installer’s responsibility to ensure that all documentation is
passed on the users and read fully before operation.
8. Failure to provide adequate structural strengthening, prior to installation can result in serious personal injury or damage to the
equipment. It is the installer’s responsibility to ensure the structure to which the Lift System is affixed can support four times the weight
of the system.
9. Risk of electric shock. Do not attempt to open the Control Box.
10. To reduce risk of fire or electric shock, do not expose parts to rain or other liquids.
11. Protect the power cord from being walked on or pinched.
12. Keep all documentation.

TV HAZARD
LID HAZARD
CAUTION: Avoid contact with the TV and
Lift System during operation. Use with
caution.
CAUTION: The lid of your enclosure must be
installed as described in the instructions, using the
Steel Threaded Tapered Pins. Installing the
enclosure lid in any other fashion will create
hazardous pinch points that can cause serious
personal injury. More info on page 25 & 26.
CAUTION: FOR UNDER FLOOR INSTALLATIONS ONLY:
Do not, under any circumstances, allow any person or
pet to position themselves underneath the TV at any
time.

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. The method of
installation for each type of remote control is slightly different, so you should now identify which type of remote you have by
reading below, and then follow the instructions for that type of remote.
NOTE: If you will be using the Lift with a home control system (like the ones made by companies such as Crestron or Control 4) the
most common form of control is to WIRE IT DIRECTLY to the relays of your home control system. This direct-wire method is called
Integration by Contact Closure, and is accomplished by using the Contact Closure Hardware that is supplied with the IR Control Kit
to connect the Lift to your home control system.
Before You Begin the Installation: Identify Your Control Type
IR (Infrared) –This control option allows you to utilize a 3rd party universal style remote control to raise and lower the TV Lift.
Your universal remote will “learn” the IR codes from the provided IR Handset, which will enable you to control the lift. The universal
remote will then communicate with the “eye” located on the IR Receiver via your 3rd party emitter (or flasher). Instructions for
setting the TV Lift’s travel limit are on Page 30.
NOTE: If you are NOT planning on using a 3rd party Universal Remote, switch to the RF setup. (There is no charge for swapping)
These are the parts included with IR controls:
Contact Closure Hardware IR Receiver IR Handset Height Limit Insert
RF (Radio Frequency) - This system utilizes a wireless remote control handset that sends a radio signal to the RF Receiver. The
radio signal can go through cabinet walls and does not require line-of-sight. Instructions for setting the Lift System travel limit are on
Page 30.
TIP: Planning to integrate the TV Lift with your UNIVERSAL REMOTE CONTROL? The RF version of the Nexus 21 controls won’t do it. Switch to IR.
These are the parts included with RF controls:
Backup Switch RF Receiver RF Handset Height Limit Insert
Integration by Contact Closure –To direct-wire the TV Lift controls to a home control system (Crestron, Control 4, AMX, etc.)
you will use the Contact Closure Hardware. You won’t use any Nexus 21 receiver or handset for this type of control because you will
use the handset or control pad that comes with your home control system. Instructions for setting up the System using Contact
Closure are on “Page 31”.

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.
Space requirements for the L-75s Lift System are as follows:
Depth= TV Depth + 6.85” or a minimum of 9.75”, whichever is greater.
Height = TV Height + 2”, or a minimum of 38”, whichever is greater.
Width= TV Width + 2”
IMPORTANT NOTE: The Lift System must be mounted as high up as possible inside the cabinet, so that when
the Lift is in the fully “DOWN” position (fully retracted), the top of the TV will be just underneath the lid of the
cabinet. A 1/8” gap between the lid and the Top Plate is ideal.
Lift System height and mounting position:
The Top Support Brackets allow you to adjust the installation height of the Lift in ¼” increments if necessary. When fully
assembled in the standard configuration, the HEIGHT of the Lift will be a minimum of 37.8” up to a maximum of 45.8”
with the Top Support Brackets in the highest position. See installation dimensions diagram on following page.
About the Cabinet Lid (Cabinet Top)
SAFETY NOTICE:
WARNING! YOU MUST NOT DIRECTLY SCREW THE CABINET LID (TOP) TO THE LIFT SYSTEM!! THIS CREATES
HAZARDOUS “PINCH POINTS” AND MAY AFFECT THE OPERATION OF THE LIFT OR CAUSE DAMAGE TO THE
CABINET TOP. For floating lids, DO NOT USE SCREWS to attach the lid to the Lift System. Instead, use the
“Threaded Taper Pins”. This will keep the 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.
Which Lid Style Will You Use? (There are 2 Different Styles)- Hinged Lid Compatible
Floating Lid (Floating Top) –The whole top of the cabinet sits on top of the Lift System and raises/lowers with the TV.
This is the standard Installation method, using the Top Plate and Threaded Tapered Pins.
Cut-Out Floating Lid (Top) –You will “cut out” part of your cabinet top, customizing it to the size of your TV. That cut-
out lid then sits on top of the Lift System and raises/lowers with the TV. This method uses the Top Plate and Threaded
Taper Pins, but you must set up a “catch” for the cut-out lid so that when the TV lowers, the lid stops level with the rest
of your cabinet top (like a manhole cover).
