USING the AKPro ATTACHMENT KIT
The AKPro includes a high performance, rigid, solid steel plate specifically designed to attach to
a properly installed ceiling mount head made by Chief Manufacturing (for use with the
PD8130/8150) or Premier (for use with the PD8130/8150 and Viper), which may then be further
installed to the ceiling using a variety of standard Chief or Premier mounting components.
These components are not included in the kit but are available.
The ceiling mounts 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 ceiling 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, but you must ensure that
the mount is suited to support the total weight. 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

IMPORTANT CEILING MOUNT LOCATION CONSIDERATIONS
For optimum imaging results consult the
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 the 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 AK
Pro 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.
