Liebert AC4 用户手册

After determining where to place the unit, check to ensure that you have all the hardware required to 

install the panel on the surface of a wall. Obtain the needed tools and material.

• Electric drill (if surface is too hard to drive screws without pilot holes)
• Screwdriver
• Marker to denote layout of holes
• Four screws, each #10

1. Mark the wall for mounting holes, using the back of the unit as a template (see Figure 5).
2. Drill holes, if required, to install the four #10 screws that will secure the AC4 to the wall. Clean 

up the debris.

3. If the wall material is not strong enough to hold the screws securely, use wall anchors.
4. Install the top two screws—the screw heads must be small enough to slip through the larger, 

bottom portion of the pear-shaped mounting slot in the AC4 (see inset in Figure 5). The screws 

must also be large enough to extend over the edges of the top of the mounting slot.

5. Hang the AC4 on the screws, letting the panel slip down until the screws are in the smaller, upper 

portion of the slot.

6. Tighten the screws until they are snug.
7. Insert the remaining two screws in the bottom holes on the back of the panel and tighten.

Check building plans and other relevant documents to determine whether mounting the AC4 

at the selected location might cause cutting or otherwise damaging electrical or 

communication wiring or pipes.
