PLEASE READ PRIOR TO INSTALLATION
Before installation of this projection screen you should fully read these instructions to ensure you
are aware of the full installation procedure. In addition to the screen and accessories and in order to
carry out the installation you will need:
•Spirit Level
•Philips Screw Driver
•Suitable screw fixings of at least 40mm long if the wall which is being fixed into is not a
wooden structure.
In the Installation accessories you will find:
•White Cotton Gloves to be used at all times when handling the white screen fabric
•Fabric Installation tool
•Hex Keys
It is recommended that at least 2 or more people install the screen as larger screens can be heavy
and awkward to lift. Good lifting practices and lifting aids should be used as required to aid
installation.

Unpacking
Each screen is carefully packaged in our factory to ensure that it reaches you in perfect condition.
The parts may be screwed down the crate they are shipped in and these screws must be removed
prior to removal from the crate.
Do not unpack each piece from its protective packaging until you are ready to install it. This
will ensure that you do not damage any of the velvet finished pieces accidentally during installation.
Note that the Dynamic 4 is designed and recommended to be assembled on the wall so that a
clear floor area big enough to build the screen is not required. However, it can also be built on the
floor if preferred you will just need to follow the same instructions but substitute the wall for the
floor then lift and attach the screen to the wall once built. DO NOT build the screen face down on
the floor under any circumstances as this will result damage to the screen and mechanism.
The top and bottom masks will ship fastened to the rear top and bottom screen sections to
ensure that they are protected during transit. In order to remove them from the crate and for
installation remove each of the M8 locking bolts (6 in each). You will need to keep these bolts and
washers for re-installation.
.
The screen is a 8 part frame. Two ‘C’ sections (the left and right mask), a top and bottom section.
(These together with the left and right fit to the wall to form the basis of the screen. The top and
bottom masks then attach to the rest of the frame to create the full screen. The Velvet covers then
go over the screen frame to complete the installation.

Installation
•Decide on the height you want the bottom of your finished screen to be from the finished
floor level (FFL). Now add 240mm from the FFL to bottom of screen height and mark a level
line on the wall at this height. This will be the height of the top of the back plate on the
bottom screen section.
•Now mark the central left to right point for the screen (normally the centre line of the room.
This will be the centre of the Bottom screen section.
•Now using these lines to position the bottom section of screen labelled ‘BOTTOM’ fix this to
the wall using 40mm screws to fix to the wall behind. DO NOT OVERTIGHTEN THESE. They
should just be tightened loosely at this stage otherwise you will find it difficult to connect
the other sections of the screen. Use a spirit level to ensure that this section is level and
central. This is very important as it will form the basis for the rest of the screen to be built
to.
•Prepare the left end section to be fitted. There are two joining sliders which join the bottom
section and left section. These can be secured in place using the grub screws to stick out of
one of the profiles half way.
•Now lift the left section and mate the joining slider into the respective profile until the two
ends of the profile meet fully. (you may need to help line up the white bearing slider of the
mask bar to help locate it in the groove on the bottom frame as you do this).
•Using a spirit level, ensure that the left side section is vertical.
•Screw the left section to the wall using the fixing holes in the back plate.

•Tighten the grub screws in both joining sliders ensuring the aluminium section meet.
Example of fjoining slider fixing points at each corner of screen.
•Now fix the ‘TOP’ screen section in exactly the same way again tightening the joining sliders
and using a spirit level to check the level. Also fix the 40mm screws at either end of the
main.
Ensure that the top mask has been removed from the top screen section during unpacking as
per previous instructions.
You can use the stretcher bars to ensure that you have the correct spacing between the top
and bottom screen sections. Fit the stretcher bar to the bottom section of screen and rest the top
section of screen against it during installation. The top screen section must he help up by the
installer until fixed in place and not held up by the stretcher bar. This is a guide only.

You should now have 3 sections fixed looking like this:
Note that this image is of a Dynamic 2. On a Dynamic 4 you will not have the velvet top and bottom cover fitted at
this point.
•Fix the Right section to the top and bottom sections again with the sliders ensuring that you
tighten the grub screws and the fixing screws.
•You may been to slacken the screws on the top section while aligning the Right
section to ensure that the joining sliders are able to fully engage. Ensure that the ends of
the two sections meet fully together.
•Mechanically you now have all the main section sections fitted to the wall.

Mask Connections
The masks are tensioned via large spring mechanisms in the top and bottom sections (black tension
springs with carabiner end fittings).
•Hook one end of the longer set of tension springs onto the loop in the mask plate at the top
of the mask bar. Pull the hook at the other end towards the opposing mask taking care not
to release the hook as it will be under spring tension. Once you have pulled it right the way
out to the mask hook the hook onto the mask plate of the opposing mask.
•Repeat this for the springs at the bottom of the mask bars.
•Ensure that the masks are both now under tension and that no wiring has become loose in
transit or during installation that will impede the travel of the mask bar along the linear
bearing track it travels on.

Electrical Connections
•At the joint points of the screen there are electrical connections to be made. The mask
power and the smaller sensor connection. The mask power simply pushes together. The
sensor cable is on a simple M12 Screw sensor cable. Simply connect this and screw together
the connector to lock.
Ensure that the electrical connections for the Side masks and the tension springs are all in
place before you fit the top and bottom masks

Fitting the Top and Bottom Masks
•Next you need to fit the bottom mask. The bottom section fits onto the aluminium brackets
and behind the black steel brackets on the bottom section. (this is as the screen parts were
shipped)
•Lift the bottom mask into position down behind the black steel plates. Ensure that the holes
in the mask frame and the fixing points behind line up.
•Fix into position using the 6 x M8 bolts with large washers.
•Fix the sides of the bottom mask into the side sections of the screen frame using 2 of the M8
bolts and washers provided.
Tighten all M8 bolts to attach the Top/Bottom Mask.
•Fit the bottom mask spring tensioner. This is connected to the loop at the end of the bottom
mask and then onto the loop on the frame of the top mask above (note not connected to
the top mask bar). The top mask is under gravitational tension only.
•Now in the same way you fitted the bottom mask, fit the top mask ensuring that you tighten
all the M8 fixing bolts. Due to gravity pulling down on the top profile larger screens will need
2-3 people top hold the top mask profile up while the locking bolts are attached.

Electrical Connections
•At the ends of the top and bottom masks there are more motor and sensor cable to connect
of the screen there are electrical connections to be made for the top and bottom masks and
the sensor cables. Connect these in the same way you did on the side masks.
•Care should be taken to ensure that the connections are connected correctly according to
the colour coding on the plugs.
•Ensure that all the electrical connectors on the screen are connected at this stage.

Screen Covers – (Not Included on In Wall Models)
The black velvet screen covers are magnetic and fit to the black bracket supports around the screen
to complete the installation of the screen
•First fit the two top straight sections of the screen working out from the centre of the
screen. The sections are simply held in position with the making of the magnets with the
black steel plates. Each velvet section is labelled with its location on the screen.
•Next fit the Bottom straight sections again starting from the centre of the screen. Not that
these have aluminium supports on the inside which seat on top of the steel plates to prevent
the magnets sliding down at all.
•Now fit the bottom left and bottom Right ‘L’ section covers ensuring that all joints are
aligned. Any misalignment can be sassily resolved by sliding the covers on the magnet fixings
to ensure perfect joints.
•Now fit to top left and right ‘L’ sections in the same way to complete the frame.

Electrical Operation
Test all electrical operation before fitting the screen fabric
•Power on the electrical control panel
•The main control screen will be visible on the touch screen once it has booted up.
•To start operation press ‘Home’ this will set the masks to their home position (just covering
the edge of the screen surface but showing the full width aspect of the screen).
•Now press 1.78 this will move the masks to a 16/9 image size.
•Cycle between Home and 1.78 2-3 times just to initialise the masks and ensure that
everything centralises in the mask runners following transit.
If at any time a mask sticks during this initialisation procedure and becomes slack, hit stop
and then manually push the mask bar towards the middle of the screen slightly. This will free it
and continue with the initialisation sequence.
•The screen is now ready for operation and external RS232 control of operation.

Fabric Installation
Your screen is delivered with two fabrics; the black backing fabric and the main screen fabric. The
first one to be installed is the black backing fabric.
Care and time should be taken during handling and installation of the fabric. On larger screens
you will need 2 people to complete this task.
•Take the roll of fabric (White for AT POP and Black for AT WOW) and the fabric installation
tool. Start to unroll the fabric from the roll by about 500mm. Holding the top corner of the
fabric in one hand, line it up with the top left hand corner of the screen so that the edges of
the fabric are in line with the outer edges of the screen frame.
•With the fabric tool push the tool onto the fabric and down into the white plastic fabric
retaining track.
You may want to try pushing the fabric tool into the fabric retaining track without any fabric
first to get a feel for where it goes in and how much force is required. you may need to het help
holding the mask bar out of the way slightly while they are under tension.

Retaining track insertion point Fig. 8
•Now unwind enough fabric from the roll to take you to the middle of the screen. Again
ensuring that the top of the fabric is in line with the top of the screen push the fabric into
the fabric retaining track in the centre of the top rail of the screen.
•Now unroll enough of the remainder of the backing fabric to cover the screen and repeat the
process of tucking the fabric into the top right of the screen.
•You should now have the fabric hanging from the three tucked points on the top of the
screen.
•Now using one hand apply a little bit of tension to the fabric at the bottom in the middle and
then using the fabric installation tool tuck fabric into the centre bottom of the fabric
retaining track.
•Now repeat this process on in the centre of the left and then right sides. See Fig.9.
Fabric Tuck Order Fig. 9
•Now continue to tuck in the fabric along the length of the retaining track working out from
each central tuck. Only tuck max 300mm at a time in each direction and then go to the
opposing side and tuck the same amount. This will ensure an even stretch across all the
fabric.

Direction of fabric Tucking Fig.10
•Continue this process until you reach the corners of the screen. You may have to pull out the
original tucks in the top left and right corners and re-tuck them to ensure that you have no
wrinkles in the fabric.
•Ensure that you are happy that the fabric is flat and wrinkle free.
•Using sharp scissors cut the excess fabric off on the outside of the fabric retaining track
leaving a 15mm – 20mm excess.
•Work around the screen to push this excess down into the fabric retaining track. It is best to
do this in the same manner as the original tucks working out from the centres until all the
excess is tucked in.
•Now repeat the exact same process you have just done for the backing to install the white
projection fabric. Ensure that you have the ‘FACE SIDE’ label of the fabric facing out in the
room as this will be the side the projector will project onto.
Ensure that you use the white cotton gloves to handle the white projection fabric at all times
and keep it away from dust or dirt as it can easily be marked.
