3.2.1. Leveling the Cabinet
Liebert® CRV4 is installed in-between the racks, with at least one side of the unit placed beside the server
racks. Once all the components of the cabinet have been installed, level the cabinet. The following section is a
step-by-step illustration of the process of leveling the cabinet:
1. Place the cabinet at the desired location (preferably a clean and at ground). Use a movable wrench to
loosen the four xing nuts on the four leveling screw rods in clockwise direction as shown in Figure 3-8.
2. Rotate the hexagon bolts on the bottom of the leveling feet counter-clockwise till the foot is raised or
lowered to the ideal position. Use a leveling meter to ensure that the cabinet is at an uniform level state.
Refer Figure 3-8 to understand the process better.

be removed and the Liebert CRV4 unit should be xed on the mounting bracket.
