2.2 Install a Liebert MPH in a Knurr Miracel Rack
Determine where in the Knurr Miracel the Liebert MPH will be installed and follow the applicable
instructions below. Installation requires attaching two brackets to the Liebert MPH, inserting four
spring nuts into the rack and using the brackets to attach the Liebert MPH to the rack. Refer to
Figures 2, 3 and 4. (Refer to Table 2 for the dimensions of the Liebert MPH.)
The bracket is intended for attaching the Liebert MPH to the face of a frame member.
1. Use four of the 6-32 screws to attach a bracket to each end of the Liebert MPH. The supplied
brackets have four holes that match holes on each end of the Liebert MPH.
• If mounting on horizontal frame members, attach the brackets in-line, as shown in the left side of
Figure 2.
• If mounting on an upright frame member, attach the brackets at a right angle to the Liebert MPH
as shown in the right side of Figure 2.
2. Tighten the screws firmly.
3. Insert two spring nuts into the appropriate T-slot on the frame member.
Position the spring nuts to accommodate screws inserted through slots in the brackets. To move
the spring nuts, press down on each with a small, pointed object and slide each into position.
4. Hold the Liebert MPH in place and attach the top of the unit to the rack with tool-less fasteners.
5. Tighten the screws firmly.
