Lamp Replacement - NEC NP-PH1400U User Manual

Lamp Replacement

• Use the specified lamp for safety and performance.
• To replace the lamp, follow all instructions provided on page 189.
• Be sure to replace the lamp when the message [THE LAMP HAS REACHED THE END OF ITS USABLE LIFE.
PLEASE REPLACE THE LAMP 1 (or 2). USE THE SPECIFIED LAMP FOR SAFETY AND PERFORMANCE.]
appears. If you continue to use the lamp after the lamp has reached the end of its usable life, the lamp bulb may
shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause
injury.
If this happens, contact your dealer for lamp replacement.
A Lamp Characteristic
The projector has a high-pressure mercury lamp as a light source.
A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly turning the lamp on
and off will increase the possibility of its lower brightness.
CAUTION:
• DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off
and then disconnect the power cord. Allow at least one hour for the lamp to cool before handling.
• When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projector. Glass
fragments could fall if the lamp has been burned out.
Clearance for Installing the Projector
Allow ample clearance between the projector and its surroundings as shown below.
Avoid installing the projector in a place where air movement from the HVAC is directed at the projector.
Heated air from the HVAC can be taken in by the projector's intake vent. If this happens, the temperature inside the
projector will rise too high causing the over-temperature protector to automatically turn off the projectors power.
Example 1 – If there are walls on both sides of the projector.
NOTE:
The drawing shows the proper clearance required for the front, back and top of the projector.
