Cleaning The Air Filters - NEC NP-NC1402L Handbuch

2. Cleaning the Air Filters

Air filters are provided on the projector's air intakes to prevent dust from entering the projector. Clean the air filters regularly to main-
tain the performance of the projector.
The air filters of the unit are metal air filters. They can be used over and over again if properly cleaned.
• The usage time of the air filters can be checked at "Information" - "Usage" (User's Manual : page 52) on the adjustments menu.
WARNING
• If dust accumulates on the air filters, air intake to the projector will be insufficient and the internal temperature will rise, leading
to fire or malfunction.
• Do not use a flammable gas spray to remove dust from the filters. Doing so may lead to fire.
CAUTION
• Before cleaning the air filters, turn off the power, wait for the cooling fan to come to a complete stop, turn off the projector
power switch and the light power switch, interrupt the AC power supply, and make sure that the projector has cooled suffi-
ciently. Removing the filter units during operation may cause burns or electric shock if the inside is touched.

There are 3 air filters, each of which is removed differently.
• Do not wash the air filter in water. Doing so will cause the dust to clog the holes, reducing intake performance.
NOTE
• Do not bend the air filter. Doing so could damage it, rendering it unusable.
• Clean the air filter at three locations at the same time. If you clean only one or two places, the correct filter usage
time will not be displayed on the adjustments menu.
