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. before beginning installation.
DO Ensure the ceiling structure is capable of holding at least four times the combined
weight of the lift and projector. This is a minimum requirement. Follow any local or
state codes that apply to your specific area.
DO Plan out your mounting hardware and tool requirements before installation.
DO Attach the projector, ceiling closure system, or other items to the lift only when the
lift has been properly installed and tested.
CAUTION:
Anytime that you are installing or performing maintenance on the lift,
disconnect power at the receptacle or breaker/fuse panel, program the lift to
MANUAL MODE, or activate the NO MOVEMENT switch on the side of the
control box to prevent inadvertent movement of the lift.

Lens Offset
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.
Projection Distance
If using a fixed focal length lens -- the screen-to-lens distance is critical. Offset the lift
position to compensate for the lens-to-lift difference. See your specific projector
manual for detail.

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:
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. Depending upon
your lift model the location and orientation of the control box varies.
Dip switches are located under the small access panel on the Control Box attached to
the lift frame. Use a 1/16” Hex driver to open.

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.
Tools you will need:
Safety glasses, Socket set, Box wrenches, Adjustable wrench, Magnetic torpedo level
(two, if possible), Ladders or manlift, Genie Lift or heavy straps and pulleys (for DataLift
and DataLite Models), Knockout kit or Hole saw, ½” Drill and/or ½” Hammer drill.
If space permits: use
structural channel left-toright and front-to-back for
better positioning of the lift.
We recommend you install mounting hardware into a structural channel. All hardware
should be at least ½” (M12) in diameter for the DataLift (DL3B) and DataWide
(DL3W) series, or 3/8 ” (M10) for the DataLite (LCD100) series.
You should use angled stabilizers if threaded rods extend 2’ (60 cm) or more between
structural channel and the lift. You should also leave the threaded rods slightly loose to
ease in alignment and leveling after installing the lift. You need to make sure all
hardware is securely tightened at the end of your installation.

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. Take note the location of the
electrical outlet and the signal cables in relation to the lift location. Mark where you
want knock-outs for cable pass-through on the side panels -usually in the opposite
upper corners. (½” knockout for control/video cables & 1¼” knockout for AC power)
Keep these cables away from each other to avoid electromagnetic interference.
Remove the screws holding side panels from the frame, then lift out the plenum panels.
Be careful, the edges and corners are SHARP!
The lift is shipped upside-down with the specific projector’s mounting adapter bolted to
the bottom of the frame.
The outer frame will have a white sticker indicating the FRONT and TOP side of the
frame.
Note:
DataLite and DataLift models attach to the pre-installed bolts on the top of the
enclosure frame. DataWide models attach to pre-drilled horizontal holes on the front
and rear channels.
For DataLift (DL3B) and DataLite (LCD100) be sure the lift hanging hardware is installed
in the frame before mounting the enclosure to the structural ceiling.
Optional Enclosure – Mounting
Remove the mounting adapter from the bottom frame of the lift (7/16” socket/wrench).
Raise the Option 3 or 4 housing to the mounting points – add washer and nuts, then
tighten. Make sure the threaded rod you are attaching to does not protrude further
than ¼” past the nut. If there is too much threaded rod in the housing, the lift may
not be high enough in the housing – then your closure panel may contact the projector
prior to closing fully. After you have the mounting structure and/or housing installed in
the ceiling, you are ready to raise the lift into position and mount it.

Hardware Order
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).
Before you begin, be sure the threaded rods have a nut and split washer above the lift
frame, and a flat washer and nut below the frame. These can be temporarily held in
place with tape, glue or gum.
Use 3/8” hardware for the DataLite models, and 1/2” hardware for the larger, heavier
DataLift and DataWide models.
Raise the lift into position and add hardware. Follow the hardware order to ensure
stability and accuracy when leveling the lift after you have successfully mounted it.
1/17/07

Page 10
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. Level the lift from the right front to the left front.
2. Level the lift from left front to left rear.
3. Level the lift from right front to right rear.
4. Level the lift from right rear to left rear.
5. Recheck.
6. Recheck again.
7. To be absolutely positive, recheck again.
8. Tighten all hardware.
You may cut the tie wraps and remove the wood shipping blocks. Be sure to remove all
blocks and all tie wraps on both sides of the lift.
Optional Enclosure - Side Panel Replacement
If this is a plenum-rated housing, (OPT3), you can now replace the side panels that
are not knocked out. Be sure the correct panel goes on the correct side of the frame.
Next, install the strain relief/cable clamps in the panels that are knocked out, with the
screws on the inside, facing down.
It may be convenient to put the cables through at this time, depending upon the
ceiling’s finish and accessibility. If it is drop-tile ceiling, accessibility should not a
problem.
If the ceiling is a finished sheetrock or other solid material, you may need to feed the
cables through the connectors first, before you reinstall the panels.
1/17/07

Page 11
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. Be sure the cable won’t interfere with the lift mechanics.
Do not use a stereo mini connector.
(Tip / Ring / Sleeve)
Use the provided 1/8” mono mini connector.
(Tip / Sleeve)
Be sure the cables do not sag into the lift mechanism during its operation.
Remove the tie wraps and remove the wood shipping blocks. Be sure to remove all
blocks and all tie wraps on both sides of the lift.
Caution!
If you do not remove the wood blocks, and attempt to lower the lift, they will
fall out when the unit is lowered. If you forget to remove the tie wraps from
the wood blocks and scissor mechanisms, lift damage will occur.
After following these precautions, you are now ready to turn on the power switch on
the lift control box.
On the side of the control box, you will find the small black switch labeled NO
MOVEMENT. The lift is shipped from the factory with the NO MOVEMENT switch in the
ON position.
Flip the NO MOVEMENT switch to the OFF position. The LED will then blink twice. If the
NO MOVEMENT switch is on, the STATUS LED on the control box and the remote
control will be on solid -non blinking.

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.
Place the lift in manual mode - use a small point (straightened paperclip) press and hold
the OVERRIDE button then press the UP button. Release UP then release
OVERRIDE.
Test the unit by pressing the DOWN button. It should move only when the button is
depressed. The lift will stop when the button is released.

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.
Attaching the Cables
Using the hand-held remote, bring the lift down to the MAINTENANCE position. See the
separate Remote Manual to learn how to program this position. The signal, power and
control cables can now be routed into the cable management clips on sides of the
scissor assembly.
When routing the cables always start at the fixed end of the scissor on the bottom
frame. Your cable routing will end at the fixed end of the scissor on the top frame.
1/17/07
14
Page 15
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.
NOTE:
It is common practice to keep the signal cables (audio, video, RGB) separate from the
projector power and control cables to prevent signal interference. Utilize the clips on
both sides of the lift for isolation.
Raise the lift to its home position with the UP button (in MANUAL mode) slowly,
carefully, and intermittently. Observe carefully the cables rigged to the sides of the lift
and watch for any problems.
Bring the lift down with the DOWN button. Again, watch for any problems and ensure
proper overall operation. Do this several times.
If you did not set the 12-volt trigger and AC configuration, revisit Part 1 and set the Dip
Switches for your system design.
You are now ready to attach the ceiling panel closure system.

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. Close the lift up until contact is made
with the blocks.
Disconnect the AC power and remote control cables.
Support the lift with an appropriate support system (Genie Lift, winch, rope / pulley).
After the lift is secured, remove the mounting hardware. Caution: mounting hardware
may fall when removed.
Lower the lift from the ceiling, and crate for transport.
Maintenance & Safety
All Display Devices lifts are virtually maintenance-free.
Annual safety checks are suggested to insure continued reliability and safe operation.
Inspect lifting cables for wear.
Inspect drive belt/chain for any wear.
If equipped with safety strap(s), verify that they are drawing smoothly in and out of the
clutch area, and that there is no sign of wear and tear. Also check them for proper
locking operation with a quick tug on the strap(s).
Check motor and bearings for any leakage.
Verify limit switch operation.

Summary of the Remote Control Functions
The OVERRIDE and SET buttons are hidden on the back of the remote control. The
lower button is OVERRIDE and the top button is SET. A straightened paper clip or
similar device will be needed to activate them.
When using the OVERRIDE and SET buttons, these buttons must be pressed first and
released last in the sequence.
To set the show position, press and hold SET, press UP, release UP, and then release
SET.
Automatic Mode:
UP moves lift to the top position, DOWN moves lift to show position, and STOP stops
the motion of the lift.
UP, DOWN, and STOP are functional while the lift is moving.
Manual Mode:
UP and DOWN buttons move the lift only while the buttons are depressed. Unit will stop
at the top limit switch.
STOP stops the motion of the lift at the current position.
OVERRIDE & DOWN from the show position moves the lift to the maintenance position.
OVERRIDE & UP from any position will place the lift into manual mode.
OVERRIDE & STOP terminates the manual mode and returns the lift to automatic mode.
SET & UP sets show position and only works in manual mode.
SET & STOP set the maintenance position and only works in manual mode.
When in the automatic mode, press and hold OVERRIDE, then press STOP & UP
together to place the unit into test mode. This will continually cycle the lift between
home and show positions, pausing at each position. To terminate, press stop.
The NO MOVEMENT switch is located on the control box mounted to the lift frame and
disables all movement of the unit. Remote control buttons become inactive.
EMERGENCY OVERRIDE & UP raises the lift only after the lower safety switch has been
triggered.
Holding the STOP button for 10 seconds will clear the last Communication Code
(blinking LED).
