Procedure

2. Remove the screws attaching the cover vent (B) on top of the cabinet,using a T20 Torx screwdriver.

Caution!

Rotating fan blades can cause injury to body parts that come into contact withthe blades. Blades in fan units continue to rotate for a period of time, even afterthe fan has been switched off. Wait until fans have stopped rotating completelybefore starting work on or near fans.
