PLEASE READ THROUGH ALL INSTRUCTIONS (INCLUDING ACCESSORY INSTRUCTIONS)
BEFORE PROCEEDING.
This lift is designed to be used with a re mote control unit, either automatically or manually controlled
and will function without any special training in the "show position". The lift is supplied with a key
switch and can be left in the "show", "auto" or "off" position for normal operation. The "service"
position must be used only by trained technical personnel when the lift is lowered to floor level for
service/access. Normal safety requirements of handling heavy equipment must be followed.
1.PRELIMINARY INSTALLATION CHECKS:
•The support structure should hold at least four (4) times the weight of the lift and projector combined. Always
follow the building codes.
•Required space, lift support, and necessary cabling (i.e. low voltage control lines, audio/video control and power
supplies) should be considered or installed prior to the lift installation.
•Do not install the projector on the lift until the lift, hardware and any other accessories have been properly
installed and operational.
•This lift has been adjusted at factory with cables tightly packed on the drum and leveled for precise tracking,
prior to being shipped from SVS Factory. Do not remove the lift's shipping blocks until instructed to do so
(see Section 4-6). SVS scissor lifts are shipped in a slightly open position to eliminate stress on the limit
switches and to maintain a tight cable pack on the drum. If physical height measurements are taken before
the blocks are removed from the lift, they may not accurately reflect the actual measurement of the lift in a
closed position.
•All weight attached to the lift must be centered between the lift's cables. The balance point of the projector
(also called center of gravity or lens face to base box center) should be placed in line with the cables (+ /- 1").
•For ease of installation, lift can be hoisted into ceiling location with blocks and tackle or by using a ratchet
puller.
•As a reminder, clear all persons and obstructions from the lift's path during its operation. Keep fingers and
other objects away from the scissors and other moving parts. Technical Personnel should always be present
whenever the lift is in a service mode.
Page 5
2. CONSIDERATIONS FOR THE PLACEMENT OF THE LIFT:
•Before beginning the installation, check the
dimensions of the projector to be mounted
against the available space within the lift. Be sure
to include the lens or any accessories which may
add to the overall dimensions of the projector .
To be used with the 7EX Series lift, the projector
cannot be more than 32.5" Wide (82.5 cm)– see
figure 1 & 2a and 2b.
Figure 1. (Front View)
Figure 2a. (Side View)- SVS 7EX-9, 11, 13 Figure 2b. (Side View)- SVSEX-15, 18,20,22
•Preliminary measurements should also be made to layout the orientation of the projector to the screen and
projector to lif t. If the projector lens if offset, the lift position must be offset accordingly to align the lift and the
projector with the center of the screen.
3. LIFT ‘S SUPPORTING STRUCTURE:
The 7EX Series Lift can be mounted from
four ½" threaded rods spaced at 36" Wide
(914 mm) x 41" Deep (1041 mm) -as
shown in figure 3. The threaded rods must
be supported by a rigid structure and should
not extend more than 2' (0.6m). If the
length of the rods exceed 2' (from the
support structure to the lift's top mounting
holes), cross bracing should be installed
between the rods to increase the stability of
the installation -see figure 4.

If ceiling clearance allows, an "X-Y" or a cross- supporting structure is strongly suggested (as shown in two
following suggested supporting structures). This will allow front-to-back or side-to-side adjustments if the lift is
found to still be slightly offset with the screen once it has been installed.

Important note for concrete ceiling installations: when attaching the lift to a flat ceiling, SVS suggests two (2)
pieces of #P1000T Unistrut (approx. 10' long -3.04 m), to be installed on the ceiling first. Proper spacing between the 2
pieces will be based on the distance between the top four (4) mounting holes of th e lift (as shown in Figure 1) .
You should use at least four (4) ½" bolts and anchors evenly spaced our on each piece of Unistrut to distribute the weight
of the supporting structure. Attach ½" threaded rods to the Unistrut, using Unistrut #P3010- ½"" channel nuts in the
channel, along with a locking washer and nut below channel to lock into place.
IMPORTANT: IF A #2 PLENUM SHROUD OR A #12 DECORATIVE COVER ARE TO BE INSTALLED
WITH THE SVS 7EX LIFT. PLEASE READ THEIR INSTALLATION INSTRUCTION BEFORE
P ROCEEDING. THE SUPPORTING STRUCTURE SHOULD ALSO ALLOW ENOUGH SPACE TO
INSTALL THE MOUNTING HARDWARE OF THE DECORATIVE COVER AND THE PLENUM SHROUD.

4. LIFT INSTALLATION:
a. Preparation:
1. The lift is shipped in a wood crate. Remove the Philips screws from the top lid.
2. Unbolt the lift from the bottom panel of the crate to remove the lift out of the crate.
3. The warranty information and the low voltage controller are located in the white box.
b. Installing the lift in the ceiling:
1/2" THREADED ROD
1. Raise the lift, insert it into the ceiling and line
up the four (4) mounting holes of the top frame
to the ½" threaded rods of the supporting
structure. Make sure that there is a top nut and a
flat washer before the lift is mounted –see
Figure 6. Once the lift's top frame has been
1/2" HEXNUT
inserted, add a ½" Hexnut to each threaded rod.
Always leave top nut loose to allow adjustments
LOCK WASHER
until the lift is leveled.
2. Secure the lift to the threaded rods.
TOP FRAME OF LIFT
3. Check that the top frame of the lift is leveled
from front -to-back
and side-to -side.
HEXNUT
4. Secure the top nuts. Do not over tighten
the fasteners before the lift is leveled as it Figure 6.
could distort the top frame.
5. If Power Sensor is used, please refer to the
power sensor instructions, otherwise, plug in the 12 pin connector of the low voltage controller (the Key Switch
Control Box) into the 12 pin receptor of the grey electrical box, which is supplied with the lift and shipped in
the white box located underneath the lid of the shipping crate.
6. Remove the four (4) shipping Blocks from the lift. Never remove the blocks until the lift is properly installed
in the ceiling.
7. Make sure that cables are out of the way of operation.
8. Before lowering the lift, you should have some weight attached to the bottom of the lift in order to keep the
cables tight until the projector is mounted. Both cables are placed on the drum so that they start unwinding
from the inside to the outside of the drum. They are vertical to the eye bolts in the closed position and slightly
angled toward the outside of the drum to avoid friction/rubbing with the previous cable loop.
To avoid cable spill:
- Do not push the bottom frame upward once the lift has been installed.
- Make sure that there is no obstructions in the lift's path. If the bottom frame lowers onto a chair, table or any
other object, this will cause the cables to slack and spill over the drum.
5. CEILING CLOSURE INSTALLATION – Please refer to installation instructions included with the #1
Ceili ng Closure. It is the self-aligning closure system installed underneath the projector and used to conceal the
ceiling hole when the lift and projector are raised in the ceiling. It is attached to the four (4) mounting holes of
the lift's bottom frame with threaded rods.
Page 9
6. ELECTRICAL WIRING AND LIFT CONTROL:
Electrical Connections should be made at this time. The 7 Series lift is controlled with a low voltage 24v/AC
controller called the Key Switch Control Box. This controller can be easily connected to external controllers
like Crestron, AMX etc.

How to use the low voltage controller:
a. To lower the lift to the show position, turn the keyswitch to the "show" position and press the toggle down.
The lift will stop once the roller compresses the show microswitch. The service mode is used to bypass the
adjusted show position and to set the lift in a service mode, turn the keyswitch to the "service" position and
press the toggle switch down. When the lift reaches its down limits, the lift will stop.
b. To raise the lift back to a storage position, turn the keyswitch to "service" and press the toggle switch up. The
lift will stop once its top frame compresses the up limit switches.
Note: The "up" switch works in both "service" and "show" position on the key switch.
Important: when the lift is set in a service mode, the lift will lower until it has reached its down limit switches.
The toggle switch on the control plate needs to be pressed at all times to activate the lift. It is designed as a
safety feature (the lift can be stopped at any time). The key is an extra precaution as well: when removed, the lift
is secured. If an external controller is use, please make sure that no object is standing in the lift path as it lowers
to a service position.

7. MOUNTING THE PROJECTOR:
After checking the lift operation and all clearances, the projector can be installed. The projector can be mounted
in two ways: inverted or platform mounted.
–The projector can be attached to the lift by using
a #9 Mounting Bracket, which is the actual
connecting hardware between the projector and
the lift. The base box of the #9 mounting
bracket will need to be bolted to the lift. On
the SVS 7EX lift, the mount will be secured to
PROJECTOR
the "U" shape cross member (saddle of the lift).
The mount base should be centered side to side
with the lift frame.
Figure 9.
–If the projector is non- invertible, it can be placed on a SVS #13 platform (metal shelf used to support
projector).
Note : All weight attached to the lift must be centered between the cables. Balance point of the projector should
be placed in line with cables with +/- 1" of difference.
8. CABLE MANAGEMENT:
- For SVS 7EX -9 Lift, SVS 7EX-11 Lift, SVS 7EX-13 Lift:
These lifts feature cable retainers installed on the scissor extensions in the rear of the lift. These retainers are
used to keep cables and other cords securely out of the way during operation. It is not suggested to attach the
cables to the scissors of the lift as they could get repeatedly pinched when the lift raises and lowers. To keep
projector cords away from scissors, please attach cords as demonstrated in figure 10a.

- For SVS 7EX -15 Lift, SVS 7EX-18 Lift, SVS 7EX-20 Lift & SVS 7EX-22 Lift:
These lifts feature a spring loaded cable retractor installed on the scissor extensions in the rear of the lift. This
lift features a automatic cable retractor used to keep the video cables away from the scissors during operation.
This retractor is spring loaded and automatically retracts as lift ascends or descends. figure 10b.
Figure 10b.
Instructions:
1.Lower the lift down to its maximum down position
2.Wind reel clockwise to the following specifications:
- For SVS 7-15, SVS 7-18 and SVS 7-20 lifts, wind 6 complete turns.
- For SVS 7-22 lift, wind 8 complete turns.
3.Lock in this position by placing rods or long screwdriver between reel gaps next to retractor bracket. This will
stop the reel from free wheeling.
4.Clamp yo ur cable securely at the top frame of the lift, using out riggers.
5.Attach upper half of cable to reel between two of the 4 holes with 3/16" tie wraps. Leave wrap semi- loose in
case adjustment is needed
6.Make one and one half turns around the reel counter cl ockwise. Lock cable in the same way as previous step,
to the remaining two holes (180 degrees from first two holes used).
7.Clamp cable securely to lower outrigger on bottom frame -same as #4 step.
8.Run lift up and down to check slack in cable. Cable will be slacked at the top of the lift when in a full up
position, as it will equally be slacked in the full down position.
Note: the cable retractor is located at the center of the scissors, but due to uneven amounts of scissors and
opening time of scissors, there can be slack either at the top or bottom at various positions as the lift lowers.
To accommodate the slack, the clamping on the reel point can be adjusted after tracking up and down. If the
slack is adjusted correctly, the cable will be more even when in the up and down position, with slack
occurring only in the middle position.
9.When proper position is achieved, you can then securely tighten wire tie wraps.
Page 13
9. SETTING THE SHOW POSITION:
The show position is adjusted by loosening the thumb-screw on the show microswitch bracket, located on the
upper motor frame -as seen in figure 11:
a. Operate the lift in a service mode and lower
REAR OF LIFT
the lift to the desired show position.
b. Loosen the thumb screw and slide the show
microswitch along the roller guide until it
touches the larger retainer washer (as you
ADJUSTABLE SWITCH
position the switch over the roller, you should
hear a slight click when the microswitch is
compressed). Make sure that the microswitch is
not positioned too close to the washer because
it must pass over it when the lift lowers to a
service position.
c. The show position is now set. Raise the lift
back to a closed position, turn the key switch to
the "show" position and press the toggle down.
The show
position is adjustable with an accuracy of
+/-1/8" (0.32 cm).
Figure 11.
10. MAINTENANCE AND ADJUSTEMENTS
•Inspect the lift occasionally for any looseness of bolts, check cables and clamps. Pillow block bearings are pre-
lubricated and motor does not need attent ion. If magnetic brake does not hold properly, it must be replaced
immediately.
•
Level corrections are to be made (with projector mounted) after confirming that the cable is packed tightly and
is straight on the drum.
•Position a level across the front of the projector. Fine alignment is done by adjusting nuts on the bottom of
the eye bolts. Track up and down until satisfactory alignment is achieved.
•For projectors mounted within the ceiling and lowered to a viewing position, level adjustments must be made
at the viewing level.
•After adjustments are completed, check all bolts and clamps for tightness.
•Check drum lock solenoid occasionally – see if arm raises during down travel – all other times it stays in a
locked position. If the solenoid does not pull up, the microswitch will not start motor in the down position.
Check the centrifugal cam located on the drum stop block. It should be able to move freely and will drop
when it reaches the top of the drum, this avoiding contacting the arm of the drum lock. If drum rotates fast,
the cam will lock the arm after the first rotation.
•All scissor bolts are adjusted for no slack, but must not be too tight. To adjust, tighten to approximately 151
Lbs Torque, then back of 1/8". These bolts have nylon locking nuts and should stay at this position.
