WN-5220-V Module Level Service Guide

Length of time between air filter replacements depends on the environment in which the

VideoWall is operated. Air filter cleanliness should be monitored often and the air filter

replaced at least every 3000 hours of operation. An excessively dirty air filter can block

airflow to the optical assembly and cause excessive heat buildup inside the VideoWall.

The air filter is most easily accessed from the rear of the VideoWall by first removing

the lamp access cover.

NOTE

Use care when removing the air filter to avoid causing accumulated dust to fall into the

optical assembly.

1. Turn off the power

Switch off the WN-5220-V using the remote and allow the

cooling cycle to complete (3 – 4 minutes) before switching off the

AC power at the rear-panel switch.

2. Unplug power cord

Remove the AC power cord from the WN-5220-V.

3. Remove screen or

lamp access cover

To gain access to the filter from the front of the VideoWall,

remove the screen first.

To gain access to the filter from the rear of the VideoWall,

unfasten the 8 quarter-turn screws on the lamp access cover and

remove the cover.

4. Remove the filter

From the rear, pull the filter straight out.

From the front, pull the filter up and to the right. Gently work

the filter out of the VideoWall.

5. Remove residual dust

Vacuum away any dust around the fan and filter supports.

6. Install new filter

Install a new filter with the arrow on the top edge up and

pointed toward the optical assembly (front of display).

Some air filters are not marked with an arrow. When installing

these filters, the wire mesh side of the filter should be facing the

fans.

7. Replace the screen or

lamp access cover

8. Check for airflow

Turn the unit on and verify that the fans are working.
