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.

Table 3-3 lists the available lens options for the PD7170 and their associated 
throw ratios. 
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.

Vertical and Horizontal 
Lens Shift
You 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 PD7170 provides up to 65% of vertical lens shift up or 
down. For example, with a 100 x 56 inch (1.78:1) screen, you can shift the image 
up to 36.40 inches (0.92
 meters) above or below the screen center.
Horizontal Lens Shift: The PD7170 provides up to 30% 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 30.00 inches (0.76
 meters) left or right of the screen center.
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.
Figure 3-6. Folded Optics
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.
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.

Lens Replacement
The PD7170 is shipped with the standard (1.82 – 2.28) projection lens 
pre-installed. If your installation requires a different lens, proceed as follows to 
remove the standard lens and replace it with the required one.
1. Using a Phillips screwdriver, 
remove the two screws holding 
the projector front cover in place.
 
 
 
 
 
 
 
 
 
2. Gently pull the cover away from 
the projector at each side to 
detach it.
 
 
 
 
 
 
 
3. Remove the cover and set it aside. 
 
 
 
 
 
 
 
4. Locate the lens release lever, above the lens cavity.

5. Press and hold the lens release 
button. Then, grasp the lens by the 
front and rotate it 
counterclockwise until it stops 
(approximately 30 degrees). 
 
 
 
 
6. Pull the lens straight out to remove it.  
 
 
 
 
 
 
 
7. Remove the trim ring attached to 
the motor housing on the lens you 
just removed. To do this, remove 
the two screws and two metal 
clips that hold it in place. 
 
 
 
8. Attach the trim ring to the motor 
housing on the new lens. 
9. Note that the lens mount flange 
has a female socket connector for 
the lens motor on the right side of 
the flange. (The lens assembly 
motor has a male socket 
connector that mates with this 
connector.)
 
 
10. Hold the replacement lens assembly with the motor facing to the right. 
Carefully insert the back of the lens assembly into the hole in the lens flange. 
11. Slightly rotate the lens assembly counterclockwise to align the motor 
connectors on the lens and lens flange. Gently push the lens assembly in 
until it is seated flush against the flange and the motor connectors have 
seated.
12. Carefully rotate the lens assembly clockwise until it stops and the metal clips 
at the back of the lens “click” into place. 
13. Replace the projector front cover.

Mounting the PD7170
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 PD7170 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 31.
3.6 
Connections to the 
PD7170
Proceed as follows to connect the PD7170 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.
Use only the Planar-approved ceiling mount kit designed for 
your projector. Install the mount kit according to the 
instructions provided with it. Note
