- Determine final location of the lift hole at the false ceiling. Shifting of the false ceiling hole position to the left or right side
would be required depending on the design of installed projector. The lift hole localization at the false ceiling must
provide, that the installed projector lens optical axis will be perpendicular to the screen surface and will cross the screen
at the middle of screen width. (see picture 4).

- Cut off the hole in the false ceiling (see picture 5). Cutting edges should be straight and accurate, cut tile will be used
to mask lift's shaft hole, when the lift will be at upper position.
- Check ceiling surface located just over the cut hole for bumps and level, your lift will be fixed there. Eliminate
recognized problems when possible, other problems and improper ceiling leveling would be fixed during lift installation by
use of spacers (not included at lift's set).
- Appoint location of holes for the anchors fixing lift mechanism to the real ceiling. Use installation template supplied with
the lift (see picture 6) .
- Drill holes in the ceiling at appointed locations, place anchors at drilled holes (see picture 7)
- Fix temporary lift with anchor screws (see picture 8).
- Check if lift frame sides are parallel with false ceiling hole edges, it is required for proper lift operation (see picture 9).
Release screws fixing lift's ceiling brackets to the frame to fine tune lift position. Once lift will be positioned correctly tight
bracket fixing screws and lift's anchor screws .
- Check lift leveling, use lift's frame as survey base. Fine tune lift levelling if needed by placing objects like washers
between lift frame and ceiling surface.
