3.3 Mounting the LED1081

There are several methods for mounting the projector. Depending on your chosen installation, one method may be more suitable than another.

Floor Mounting (Upright)

In typical front and rear screen installations, the projector can be mounted to a secure and level surface such as a table or cart. Carts are useful when moving a projector during a presentation or from site to site. If possible, lock the wheels when it’s in position to prevent it from being moved during a presentation.

Ceiling Mounting (Inverted)

For fixed installations, and for those that want the projector out of sight or have a limited space for projector and audi- ence, you can invert the LED1081 and suspend it from the ceiling using a specially-designed ceiling mount fixture.

Note

Note

Use only the Knoll Systems-approved ceiling mount kit designed for your projector. Install the mount kit according to the instructions provided with it.

When installing, ensure that you use only UL Listed ceiling mounts.

For ceiling installations, use approved mounting hardware and M4 screws with a maximum screw depth of 8 mm (0.31inch).

The construction of the ceiling mount must be of suitable shape and strength. The ceiling mount load capacity must exceed the weight of the installed equipment, and as an additional precaution be capable of withstanding three times the weight of the equipment (not less than 48 kg) over a period of 60 seconds.

Adjusting the Projection Angle

If the screen is significantly higher or lower than the projector, you can also tilt the projector at a slight angle. In a ceil- ing installation, you do this by adjusting the ceiling mount.

For a floor installation, turn the adjustable feet at the bottom of the projector to adjust the projection angle.

If you do this, you may need to vertically shift the image to compensate. For detailed instructions, refer to Lens Adjustments on page 32.
