REINSTALL FRONT PANEL

1. Grasp the front panel firmly at the center of the top and bottom of the panel, tilting it forward 5 to 10 degrees from the vertical. See Figure 4.

2. Place the top of the front panel onto the unit, making sure the top engagement posts have engaged the slots on the unit. The top edge of the front panel should be flat against the top of the unit.

3. Gently lower the front panel onto the chassis, ensuring the conduit/cord is routed through the panel notch. Magnetic latches at the bottom of the front panel will secure the front panel to the unit.
