Raised Floor Mounting Instructions
To mount the Liebert FS cabinet on the floor:
1. Prepare a clean, level finished surface, free of obstructions, for installation of mounting kit.
2. Tape the floor mounting template (see Figure 149) to installation location, pre-drill a pilot hole,
then remove paper and continue with 5/8" (16mm) drill bit.
3. Match mounting brackets with holes under base of cabinet (see Figure 21). Make sure that the
bracket holes align with the mounting spots on the underside of the cabinet and secure brackets
with the four 1/2" diameter x 3/4" long (12.7mm diameter x 20mm long) hex bolts retained from
the shipping package. The bolts must be tightened to 40 foot-pounds (54 N-m) of torque.
4. Position and align cabinet and bracket slots with the newly drilled holes (see Figure 22).
5. Insert four drop-in hex flange bolts through bracket mounted at front and rear of cabinet (see
Figure 23).
