Screen Technics Interfit Projector Lift Manual

Interfit PROJECTOR LIFT Models C, D and F Type
Thank you for purchasing a Screen Technics AV Lifter
and please ensure to read the instruction fully before
proceeding to install the unit.
General Advice

The Interfit AV Lifter is a fully integrated unit that is designed to be installed above the ceiling line of the room and utilises
bottom ceiling edge trim pieces to create a neat finish against the ceiling material cut‐out.

No plaster or paint trades are required for this standard installation.

All electrical and control equipment is contained in the ceiling space. A standard 3 pin GPO for power supply is required.

Review the cut‐out dimension fact sheet attached to the top lid of the unit, as model sizes vary throughout the range.

Before proceeding ensure that you have enough in‐ceiling height to fit the unit. And that your model lifter will
accommodate the projector that is specified for the project.

Make sure you have reviewed the Lens Throw Distance Chart provided with the projector so that the Lifter will be the
correct distance from the projection screen and to allow for any sideways lens off‐set to achieve a perfect result.
Installation Advice
Having decided on the position of the Lifter you must now cut the ceiling material to the stated cut‐out dimension. We recommend
that you divide the cut‐out in two and remove one half at a time to prevent torn edges.
Every above ceiling environment is unique and therefore there is no singular approach to securing the unit
within the ceiling space. Following are some accepted install practices:
Please Note: If the ceiling environment is going to be sealed without man‐hole access up into the roof, then for
later service removal, it is important to use the elongated vertical slots on the lower half of the frame uprights
to secure the supplied angle brackets. This will allow (with some difficulty) removal of the device from below if
mechanical failure occurs.
Chain and Turnbuckle

Secure the chain to a suitable structure, such as overhead timber beams, or dyna‐bolted to an
overhead concrete slab.

A minimum of 4 points to secure the chain is required and it is the installers responsibility to
ensure the chain turnbuckle system chosen is strong enough for the safe installation of the
unit.

Now raise the unit into the ceiling, hold in position from below while a second person
secures the other end of the chain to the lifter using the supplied angle brackets and tighten
the turnbuckles till the units ceiling edge trims are firmly pressing against the underside of
the ceiling material.

Lock off the turnbuckles.
