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.

ON OFF
SW1 Aux AC Trigger (see SW2 below) Aux AC Trigger is on all the time
SW2 Aux AC Trigger upon going down Aux AC Trigger at show position
SW3 12V out turns off upon going up 12V out turns off at top position
SW4 12V out turns on upon going down 12V out turns on at show position

Dip Switch SW1: configuration only works in automatic mode.
Set the 12 volt trigger and AC Trigger based on your system design.

The factory default setting will not change for most installations.

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.

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.

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.
