Ambient LightIn general, minimize or eliminate light sources directed at the screen. Contrast 
ratio in your images will be noticeably reduced if light directly strikes the screen, 
such as when a shaft of light from a window or floodlight falls on the image. 
Images may then appear washed out and less vibrant.
Throw DistanceThrow distance is the distance measured from the front of the projector to the 
screen. This is an important calculation in any projector installation as it 
determines whether or not you have enough room to install your projector with 
a desired screen size and if your image will be the right size for your screen.
You can quickly estimate the throw distance by taking the width of the screen 
and multiplying it by the lens throw ratio; see 
Figure 3-2. The result of this 
calculation tells you roughly how far back the projector should be positioned 
from the screen in order to project a focused image large enough to fill the 
screen.
Figure 3-2. Estimating Throw Distance
The standard PD8130/PD8150 offers a throw ratio of between 1.85 and 2.40. 
With the optional, short-throw accessory lens, the PD8130/PD8150 offers a throw 
ratio of between 1.56 and 1.86.

Vertical and Horizontal 
Position
Proper placement of the projector relative to the screen will yield a rectangular, 
perfectly-centered image that completely fills the screen.
Ideally, the projector should be positioned perpendicular to the screen and in 
such a way that the lens center is aligned with either the top or bottom edge of 
the screen area, and centered horizontally. See 
Figure 3-3.
Figure 3-3. Projector Placement
Vertical Lens ShiftYou can use the lens shift controls on the projector to center the image on the 
screen. Lens shift is generally expressed as a percentage of the screen height or 
width, as shown in 
Figure 3-4 and Figure 3-5.

Vertical Lens Shift: The PD8130/PD8150 provides up to 25% of upward vertical 
lens shift and up to 60% of downward vertical lens shift. For example, with a 100 
x 56 inch (1.78:1) screen, you can shift the image up to 14.00 inches 
(0.36
 meters) above or 33.60 inches (0.85 meters) below the screen center.
Horizontal Lens Shift (PD8150 Only): The PD8150 provides up to 7.5% of horizontal 
lens shift left or right. For example, with a 100 x 56 inch (1.78:1) screen, you can 
shift the image up to 7.50 inches (0.19
 meters) left or right of the screen center.
Figure 3-5. Horizontal Lens Shift (Example Only)
1. With no vertical or horizontal lens shift, the lens center and 
screen center are aligned with each other.
2. Vertical shift limits are percentages of the screen height. 
Horizontal shift limits are percentages of the screen width. 
3. Vertical lens shift figures are for ceiling mount 
configurations. For floor installations (where the projector 
is upright), reverse the up/down vertical lens shift 
percentages.

Folded OpticsIn rear-screen applications where space behind the projector is limited, a mirror 
may be used to fold the optical path, as shown in 
Figure 3-6. The position of the 
projector and mirror must be accurately set. If you are considering this type of 
installation, contact your dealer for assistance.

Other ConsiderationsOther considerations and tips that can help improve your installation:
• Keep the ambient temperature constant and below 35°C (95°F). Keep the 
projector away from heating and/or air conditioning vents. Changes in 
temperature may cause drifts in the projector circuitry, which may affect 
performance.
• Keep the projector away from devices that radiate electromagnetic energy 
such as motors and transformers. Common sources of these include slide 
projectors, speakers, power amplifiers and elevators.

Mounting the 
PD8130/PD8150
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 audience, you can invert the PD8130/PD8150 
and suspend it from the ceiling using a specially-designed ceiling mount fixture. 
 
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 ceiling 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 30.
Use only the Planar-approved ceiling mount kit designed for 
your projector. Install the mount kit according to the 
instructions provided with it. Note

Connections to the 
PD8130/PD8150
Proceed as follows to connect the PD8130/PD8150 to your video sources, 
external controller(s) – if present – and AC power.
When connecting your equipment:
• Use the correct signal cables for each source.
• Ensure that the cables are securely connected. Tighten the thumbscrews on 
connectors that have them.
Connector Panel AccessUsing a flat-blade screwdriver, loosen 
the two screws holding the rear 
compartment cover in place. 
 
 
 
 
 
Then, remove the rear compartment 
cover by tilting it upward.
