weight capability of this unit and not exceeded.
Before installing the projector lift, please read the following instructions carefully:
• The projector lift must be used INDOORS ONLY.
• Please confirm that your projected image width will fit your screen from your
proposed mounting location prior to installation.
• Incorrect use of the lift, including exceeding the maximum lifting weight, would be
dangerous. The manufacturer does not take responsibility for any damage to property or
personal injury if the lift is used outside of recommended specifications.

INSTALLATION INSTRUCTIONS
Use the HEX-headed screws listed as “F” in the equipment list, to mount the “L”
brackets to the profile of the lift, as shown in PICTURES 1A, 1B and 1C below:
Mount the lift to the ceiling using the suitable bolts/screws (NOT SUPPLIED) and verify that the
projector lift is perfectly horizontal using a sprit level. Use shims to level the lift, if required, between
the brackets and ceiling.
Installing the lift perfectly level is IMPORTANT and ensures silent movement of the lift without any
shaking, jolting or friction that would compromise the alignment between projector and projection
screen.
Once you have mounted the lift, position the projector either on or under the grill using the screws
indicated in the instruction manual of your projector, as shown on PICTURES 2A, 2B and 2C.
Connect the projector lift to the electricity supply as explained on the attached instructions for electrical
connections (D).
The next step is to set the “CLOSED STOP POSITION” (CLOSED lift) and the “BOTTOM STOP
POSITION” (OPEN lift).
If the projector lift has been positioned inside a false ceiling void, please be aware that to allow full
closure the threaded bars that support the trim kit must be no longer than 25cm in length. (E) in the
equipment list on page 1. The “BOTTOM STOP POINT” has to be regulated so that the image is
correctly projected onto the screen.
In order to fix the “CLOSED STOP POSITION” : turn the white screw on the motor anticlockwise to
position the lift nearer to the ceiling. Turning clockwise increases the stop point Gap .
In order to fix the “BOTTOM STOP POINT” : turn the yellow screw anticlockwise to increase the drop
and clockwise to reduce the drop.
Once you have fixed the “CLOSED STOP POSITION”, cut the threaded bars to the correct length to
allow flush fitting of the trim kit suspended from the grill to the ceiling. Mount the bars to the profile of
the lift and fix them to the mounting plates, using the M6 nuts supplied, as in PICTURES 3A, 3B and 3C
below.
Fit and align the trim kit by hanging the threaded rods from the slot as Picture 3C.
If the panel is not balanced, move the projector lift either releasing the screws that lock the “L”
brackets to the aluminium profile making them sliding or releasing the screws that anchor the brackets
to the ceiling using the sliding hole milled out of them (max 3 cm. the hole on the ceiling is central).
If the lift does not line up horizontally to the false ceiling, modify the length of the bars or the “CLOSED
STOP POSITION”, following the instructions above described.
The signal and power cables should run inside the plastic channel supplied. Remove the upper side of
the plastic trunking and place the cables inside as shown below. ( Pictures 4A & 4B )
