Using the AKPro Attachment KIT

The AKPro includes a high performance, rigid, solid steel plate specifically designed to attach to a properly installed model RPA ceiling mount head made by Chief Manufacturing, which may then be further installed to the ceiling using a variety of standard Chief components. These components are not included in the kit but are available from most qualified home theater installers. The RPA and associated hardware must be installed to ceiling structural members to support at least 250 pounds and must be extremely rigid. Any play in the RPA mount will result in a rocking of the AKPro assembly as the lens moves in and out of the projector beam and represents a danger to equipment and personnel.

The AKPro Attachment kit may also be used with a projector mount from another manufacturer apart from Chief. If you wish to use a different projector mount the lens system is stabilized by using two chains extending from the front area of the plate to ceiling attachment points. You may skip ahead to Page 6 and the section titled: “Alternate Attachment Plate Method”

IMPORTANT CEILING MOUNT LOCATION CONSIDERATIONS

For optimum imaging results consult your projector’s instructions for the ceiling mount location to place the projector’s lens in the horizontal center (ie left to right) of your projection screen (even if your projector has a horizontal lens/image shift capability). In addition, make sure you are not at the limits of your projector’s zoom capability so that you have some range for image adjustments.

The AKPro attachment plate is designed so that the projector and other attached components form an average center of mass (gravity) approximately located at the center of the ceiling mount pipe. Therefore, the ideal ceiling mount location will be shifted by the AKPro 2” (50mm) toward the left side of the screen from the ceiling mount location indicated by your projector’s instructions.

If your projector ceiling mount is already installed and you do not wish to move it (or similarly move the screen in the opposite direction) due to a shift by the AKPro system, then you can make fine horizontal shift adjustments to your projector (if available) combined with turning the projector (only as necessary) during final setup to compensate for the shift. Some small amount of image distortion (horizontal keystoning) may result but in most cases this will not be noticeable since the image edges will typically be masked by the screen borders.

WARNING!

Use extreme caution and appropriate hardware when installing heavy objects to a ceiling. Periodically check all fasteners and connection hardware to be sure they are not coming loose. Improper installation may lead to an increased risk of your equipment becoming unstable and possibly injuring someone.
