Important Installation Notes Before starting… DO Read all instructions before installation. DO Leave wood blocks in place to protect you and the lift from damage until fully and securely mounted. DO Ensure the electrical outlet is readily accessible and complies with the lift and projector specifications for voltages and amperages. (Show diagrams of 110v and 220v receptacles.) DO Check above the ceiling for obstructions, i.e., water pipes, wires, cables, duct work, extreme temperature variations, etc.
Lift Placement and Location Many projector lenses are not centered on the chassis of the projector. Ensure that the centerline of the lens is aligned perpendicular to the center of the screen. Position the lift offset the same distance as the offset of the projector lens. If your projector has horizontal lens shift this is not as critical. We recommend offsetting the lift for optimum projector alignment.
Lift Preparation Unpack Lift – remove phillips head screws & lag screws securing frame & lift to the pallet. (photo of LCD-100 with Option 4). The lift is shipped upside down. Leave the wood blocks and plastic tie wraps in place. Control Box NOTE: The factory default setting will not change for most installations. SET DIP SWITCHES before you install the lift. Be sure there is no power connected to the lift. The control box is located inside the lift on the upper frame.
Typical Ceiling Finish Methods Determine your ceiling closure system (OPT 1 – 4) and finish method as it can effect the vertical placement of the lift.
Installation – Enclosure Housing and Lifts Mounting hardware is not provided unless you ordered the option UMK (Universal Mounting Kit). Be sure to have all your mounting hardware and tools readily accessible before installation. Consult your local building codes for proper structural attachment.
Optional Enclosure Housing –Side Panel Removal If you are not installing the OPT3 (Plenum Housing Enclosure) or OPT4 (Non-Plenum Housing Enclosure) proceed to Part 4. The OPT4 is the enclosure frame without side panels. You may skip the steps on the OPT3 panels if you are installing the OPT4 only. Use a Sharpie pen to mark the alignment of the side panels to the frame so you can reinstall them from the side they were removed from.
Lift Installation CAUTION! The lift is heavy. Take proper safety precautions and get adequate help when raising the lift. We recommend using a Genie™ or scissor-type lift when installing the heavier DataLift and DataWide models. Add a safety line to the lift to prevent it from falling to the floor in the event of an accident. Remove the mounting adapter from the bottom frame of the lift (7/16” socket/wrench).
Note: The following are some of the most important steps in proper lift installation! Use a torpedo or bubble level to level the top frame of the lift. You may want to use more than one. 1. 2. 3. 4. 5. 6. 7. 8. Level the lift from the right front to the left front. Level the lift from left front to left rear. Level the lift from right front to right rear. Level the lift from right rear to left rear. Recheck. Recheck again. To be absolutely positive, recheck again. Tighten all hardware.
Connecting Power Verify voltage at the outlet/power source for the projector/lift. You can now connect the lift’s power cord to a properly rated electrical circuit in the ceiling near the lift. Next, plug the remote control unit cable into either of the two 9-pin control remote ports on the side of the control box. Tighten the cable clamps / strain relief connectors as required. If using the 12V trigger and/or AC Trigger, plug 1/8” mono mini plug on the sides of the control box at this time.
Caution! Make sure all tools, cables and body parts are clear of the lift before pushing the UP button. With the hand-held remote control, press the UP button to send the lift to the home position. Refer to the separate manual for the remote control (enclosed) for details on operation of the remote and program the lift’s functions.
Projector Mounting Most lifts are shipped with the projector mounting adapter attached. Remove it from the lower frame of the lift, if you have not already done so. Find the projector’s center of gravity using a dowel, pipe or broom handle. Invert your projector and attach the mounting adapter to the bottom of the projector with the enclosed hardware. Use the Remote Control to lower the lift to a good working height – see the Remote Control Operation section for further information.
Cabling the Lift Caution: Using large-diameter RGB and other signal and/or control cable is not recommended on Display Devices’ lifts. This type of cable has too large of a bend radius to allow it to fit in the cable management clips mounted on the outside of the scissor assembly. If your system uses large cables, keep them coiled neatly to the top of the lift, and provide an interconnected miniature RGB cable to make the run down through the cable management clips to the projector.
The lift is shipped with a sample cable in the clips – after reviewing the sample cable remove. Attach your cables in a likewise manner. Small cable tie wraps are supplied for securing the cables into the clips. Use both of the small holes when attaching the cables to the clips. Leave a loop at the end of each scissor. Carefully route the projector cables starting at the bottom scissor towards the front of the lift and work towards the top front of the lift. Be careful you do not allow the cables to twist.
Ceiling Closure System – CTB Mounts & Sliders Slider (X2) Threaded Rod Assembly (X4) CTB Mount (X2) Option 1 Lipless Ceiling Closure Frame CTB Mount (X2) Slider (X2) Threaded Rod Assembly (X4) Option 1 Lipped Ceiling Closure Frame NOTE: If you are not installing an OPT1 Ceiling Closure Frame, proceed to Part 8. Lower the lift to a workable height. Install the CTB mounts to the corresponding holes in the front and rear on the lower frame of the lift.
NOTE: If you have the 2X2 configuration, you will not use the sliders (front-to-back bars). CTB Mount (X2) Option 1 2X2 Lipless Ceiling Closure Frame For a Lipless Closure System (OPT1L, OPT3L) cut a plywood backer board and ceiling media (drywall, ceiling tile) 3/8” smaller than the hole cut out in the ceiling. Glue or screw the ceiling media to the backer board. Add two 1” x 4” wood supports across the width of the closure frame. Screw through the wood supports into the plywood backer board.
Ceiling Closure System – Threaded Rod Attachment Thread the (4) ¼-20 rods into the ceiling closure frame, stopping about 1½” from the bottom. Lift the closure panel and insert the rods into the slider. Add the nylon shoulder bushing, spring, ¼” flat washer, and ¼-20 lock washer on the top end of the rod. Carefully raise the lift using the remote control. Be sure the inner closure frame is centered inside the OPT3 or OPT4 outer frame.
Final Adjustments Operate the lift up and down several times to verify all adjustments and ensure proper overall operation. Place the lift in Manual Mode – press and hold Override, press and release UP, relase Override. Raise the lift to its home position with the UP button slowly, carefully, and intermittently. Observe carefully the cables rigged to the sides of the lift to watch for any problems. Bring the lift down with the DOWN button. Again, watch for any problem and ensure proper overall operation.
Lift Removal Disconnect all cables from the projector. It may be necessary to remove all cabling from the cable management clips on the side of the lift if disconnects were not installed. Remove the Ceiling Closure Panel. Remove the projector from the lift. Place wood blocks between the upper and lower frame of the lift, and secure them with tie wraps. The wood should be ½” to 1” longer than the fully-retracted lift height to prevent the limit switches from being crushed.
Emergency Operation If your lift has traveled below the service position, and activated the lower limit safety switch, you will need to refer to the Remote Manual, and/or follow the steps below. 1) Open the back cover of the handheld remote control case, or remove the switch plate from the wall box. (More detailed information is in the Remote Control Manual page 26.) 2) Press and hold the STOP button for 15 seconds to clear the error.

Recover Lift from LOWER LIMIT SWITCH ACTIVATION and EMERGENCY OVERRIDE When the Lift is lowered beyond its lower limit or Service/Maintenance position, a small wheel bearing activates a safety shut-off on the lower limit switch. It is located on the channel near the wheel bearing on the scissors. If the lift will not respond to any command buttons and the LED on the remote and Control box blinks seven times, proceed with the following. The procedure is also required if a new control box is installed.
