secure the new fan assembly to the rear panel.
Cleaning and replacing the front-door air filter
Cooling air pulled into the frame by the rear fan assemblies passes throught an air filter located
in the front door of the frame.
• Check the flter regularly to ensure that it is not clogged with debris.
• Remove and clean the filter if it is dirty.
• Replace the filter if it is damaged or cannot be thoroughly cleaned.
To check the filter, open the front door and visually inspect it.
To remove the filter for cleaning or replacement
1 Open the front door and lift it up to slide it off the hinge pins.
2 Lay it face down on a work surface
3 Undo the captive thumbscrew at one end of the filter retaining bar
4 Slip the other end of the retaining bar out of its slot
5 Pull the filter away from the faceplate, by slipping it off the retaing hooks at the four cor-
ners.
To clean the filter, either vacuum it or rinse it in water.
If you wash it, make sure it is thoroughly dry before replacing it, to prevent moisture
from being pulled into the frame by the ventilating fans.
