This floor stand should be used when EC fans are intended to be lowered under a raised floor. The standard Liebert DS floor stand can be used if the fans are to remain in their original raised position. 2. Right side of paneled unit is flush with right side of floorstand. All other paneled sides overhang floor stand 1" (25mm). 3) The floor stand used with EC units is not symmetrical and its orientation to the Liebert DSE is critical for lowering the EC fans. Unless the floor stand is installed in the correct position, the blowers will not lower into the floor stand. 4. Jack and jack support are shipped loose and are intended to be placed into position under each fan and utilized to lower or raise that fan as needed.
