q Throw Distance and Screen Size 
Example of NP08ZL: 
The further your projector is from the screen or  wall, the larger the image. The minimum size 
the image can be is approximately 40 inches (1  m) measured diagonally when the projector is 
roughly 65 inches (1.7 m) from the wall or sc reen. The largest the image can be is 500 inches 
(12.7 m) when the projector is about 843  inches (21.4 m) from the wall or screen. 
Note: 
The following image represents the  NP4000 model. For the corresponding 
NP4001 values, see NP4001 Throw Distance and Screen Size Values on page

2. Installation and Connections 
26
CAUTION 
 Ceiling installation must be done by a qu
alified professional. Contact your 
NEC dealer for more information.  
It is not recommended you install the projector yourself. 
Only use the projector on a solid, level surface. Serious injury and dam-
age can occur if the projector falls to the ground. 
Do not use the projector in an environment where extreme temperature 
occurs. The projector must be used at  temperatures between 41 degrees 
Fahrenheit (5 degrees Celsius) and 104 degrees Fahrenheit (40 degrees 
Celsius). 
Screen damage will occur if the projecto r is exposed to moisture, dust or 
smoke. 
Do not cover the vents on the projecto r. Proper ventilation is required to 
dissipate heat. Damage to the projec tor will occur if the vents are cov-
ered.

r Replacing Color Wheel 
The NP4001/NP4000 projector comes with a f our-segment color wheel installed. An addi-
tional  
six-segment color wheel comes included. To re place the color wheel (located under the lamp 
cover adjacent to lamp 1) re fer to the following guide. 
Note: 
• Before replacing the color wheel, be sure  to turn off the projector, wait until the 
cooling fans stop, and turn off the main power switch.  
• Wait until the lamp house and the color wheel cool off. •  
• Do not touch the disk of the color wheel. Doing so may scratch the disk or leave 
fingerprints, causing the image quality to degrade. 
• Heed the following information if you own two or more NP4001/NP4000 projec-
tors: 
When replacing or re-installing the colo r wheel, the original color wheel pre-
installed or supplied as an accessory must  go back to its original projector. Your 
color wheel and projector color wheel cove r are given an identification number. Be 
sure to use the color wheel pre-installed  or supplied with your projector to match 
its identification number. 
If you remove a color wheel from one NP4001/NP4000 projector and re-install it 
into another NP4001/NP4000 projector,  performance may be compromised. 
1.  Loosen the captive 
screw (A) on the lamp 
cover. 
2.  Remove the lamp cover 
by sliding in the direc-
tion of the arrow (B).
