Prepare the Liebert CRV for Installation

4.1 Adjust Baffles to Direct Air Properly

Adjust the front panel baffles before startup to ensure the cooling air is directed upward and either

right or left as required. Proper direction helps obtain the maximum cooling efficiency from the Lie-

bert CRV unit and to prevent racks from overheating.

The Liebert CRV is shipped with the baffles in an alternating pattern. This configuration is intended

for Liebert CRVs that are installed in the row, between racks, distributing cold air left and right.

The baffles in Liebert CRVs installed at the end of a row should be adjusted to direct the cold supply

air toward the server racks.

Baffle segments nearer the top of the unit will supply more cooling air than segments near the bot-

tom. Supply air travels slightly farther when all segments are pointed in the same direction.

To adjust the baffles:

1. Open the door containing the Liebert iCOM display.

2. Remove the two screws holding a baffle panel segment in place.

3. Lift out the baffle segment.

4. There is one screw on each side of the baffle, as shown in Figure 11. Remove the screws and

rotate the baffle segment around its horizontal axis to change the airflow direction.

5. Reinsert the baffle segment and reinstall the screws.

WARNING

Risk of contact with rotating devices. Can cause injury or death.

Ensure that the Liebert CRV is shutdown and power has been disconnected before beginning

any work on the unit. The Liebert CRV’s fans will continue spinning after the unit is shut off.

Wait until the fan blades have stopped before working on the unit.
