Clearance
Normal maintenance, such as lamp module and air filter replacement,
can be performed from the front or rear of the WN-5220-S. Maintain
sufficient clearance to allow easy access from the front. A minimum of
4 feet is recommended. For full maintenance from the rear, the
minimum recommended clearance is 3 feet.
To allow proper cooling, the minimum required clearance to the rear
of the display should be 6 inches. The minimum required clearance to
the top at the front of the unit is 6 inches. See Environmental
Specifications on page 17 for cooling requirements.
If installed in a video wall configuration, a minimum of 12 inches to
the ceiling from the top of the highest display is needed if the units
are installed from the front.
Cooling
Regardless of clearances and the general ambient temperature, the
most important factor that affects reliable operation is the temperature
and quantity of air coming into the display. The intake air temperature
at the air filter must not exceed 95
°
F (35
°
C). If there is any doubt
about this temperature in an installation, run the displays for several
hours before taking temperature measurements. Prevent problems by
replacing dirty air filters and keeping the air path clear.
