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.

CONNECTING THE AKPro ATTACHMENT PLATE  
(Chief RPA mount and Phillips screwdrivers required)  
1. Position the projector bottom-up. Consult the Attachment Plate Diagram for plate orientation,  
hole positions and required screws and spacers for your projector model. Insert and tighten  
each screw through an appropriate silver washer and lock washer, the designated holes in the  
Attachment Plate, then through any required spacers and finally into the projector ceiling mount  
holes.  
2. Using the included gold hex key, install the six 7/8” socket head screws each through a 3/8”  
aluminum spacer and into the six threaded holes from the ceiling side of the attachment plate.  
Thread only enough to extend the screw to the bottom of the plate.  
3. Insure that the RPA mount head is secure (see instructions included with the RPA mount)  
and oriented properly relative to the 7/8” socket head screw heads so that the mounted  
projector will face the screen. Use two people to lift and position the projection assembly so that  
theads of each of the 7/8” socket head screws rest within the matching final location of the  
Rmount head. At this point the silver 3/8” spacers should be between the Attachment Plate  
and he RPA mount head. The projection assembly may be lowered to allow the 7/8” screw  
heads to rest on the RPA mount. However, a first person should continue to guide the  
projection assembly while and a second person uses the gold assembly wrench to tighten the  
7/8” screws. When tightening these screws, do so in a pattern of incrementally driving each  
screw a little more into the attachment plate so that at any time the projection assembly is  
resting on as many screw heads as possible until all are tightened.  
If the lens must be removed for any length of time it is recommended that a similar weight be  
suspended from the front of the attachment kit to balance the weight of the projector. This will  
minimize unusual stresses on the ceiling mount system.

2. Position the projector bottom-up. Consult the  
Attachment Plate Diagram for plate orientation, hole  
positions and required screws and spacers for your  
projector model. Insert and tighten the required screws through the ceiling mount adapter (not  
included), then through the designated holes of the Attachment Plate, and then through any  
required spacers and finally into the projector ceiling mount holes  
3. Securely connect the projector assembly to the ceiling mount and then adjust the projector  
and ceiling mount to center the projector's image in the horizontal center of your screen.  
4. Install ceiling hooks (not supplied) into the ceiling directly above the Plate Hooks. The  
ceiling hooks should be small enough to accept a Chain End but strong enough when  
installed to each support 40 pounds or more.  
5. Attach a Chain End to the Chain and then connect to one of the ceiling hooks. Cut the Chain  
and assemble to another Chain End for a best fit to the corresponding Plate Hook and attach.  
Repeat for the other set of hooks.  
6. Adjust and tighten the nuts on the Plate Hook Assemblies to make the Chains tight but  
without raising the front of the Attachment Plate. You may wish to turn the projector on to  
ensure the image remains properly oriented to the screen during this step. At this point proceed  
to the appropriate lens/transport mounting step.

2.  
Position the flat side of the  
motorized transport against the bottom  
side of the Attachment Plate so that the  
transport logo is toward the screen and  
the center “M” hole in the Attachment  
Plate is aligned with the front recessed  
transport hole. Insert the #10-32 pivot  
screw up through the transport and  
Attachment Plate and loosely complete  
the assembly with the corresponding  
washer, lock washer and nut. Now  
loosely insert the four small 3/8” screws

3.  
Refer to the ATH1 user manual (included with ATH1) for additional instructions to install  
the lens at this time, but do not forget to complete the “Final Adjustments” step below.  
FINAL ADJUSTMENTS (ALL INSTALLATIONS)  
1.  
Turn the projector on with the UH480 Lens out of the projector beam. Set the horizontal  
lens shift to neutral (if a feature of your projector) and then adjust the ceiling mount so that the  
16:9 image is in the exact center of and square to the screen, with a similar amount of image  
slightly over the top and bottom screen borders. If the projector lens is not in the exact  
horizontal center of the screen you may need to use a little horizontal lens shift for this purpose.  
2.  
Bring the UH480 Lens into the beam. Adjust the vertical position and tilt of the Lens so  
that the projector beam is passing through the center of the Lens and so any residual  
pincushion distortion is about the same at the top and bottom of the image. This will typically  
result in the UH480 Lens being below the center of the projector lens and tilted slightly  
downward. Tighten the knobs.  
3.  
Adjust the rotation of the ATH1 transport so that the left and right sides of the image are  
an equal distance from their respective screen borders. Now tighten the Pivot Screw (M380)  
and also the four remaining screws holding the transport to the Attachment Plate.  
4.  
For optimum multiple aspect ratio performance, adjust the projector’s zoom so that a  
1.85:1 aspect ratio movie (Lens “out”) is just masked by the top and bottom of the screen  
border. This way 1.85:1, 16:9 and 2.35-2.4:1 aspect ratio movies should all be presented to fill  
the screen at a constant height.

CLEANING  
In most applications lenses do not need very much cleaning – a bit of dust will not impact image  
clarity. However, in today’s high performance home cinemas with very dark rooms a small  
build-up of dust or other foreign matter on your projector lens or your Panamorph lens can  
produce a measurable reduction in contrast. The most effective cleaning approach is to simply  
blow off any dust. If there is any residue or build-up then it is recommended that you clean the  
optics with professional lens cleaning supplies such as from a camera store while the lens is in  
front of the lit beam of the projector. This will allow you to quickly see both the results of  
cleaning and also if you are causing any damage.
