2. Insert the pins in each of the pin openings located directly below the front of the dampers as
shown in Figure 4.26 below.

3. Repeat steps 1 and 2 for the remaining dampers.
4. The damper slides must be opened varying amounts to provide adequate cooling for each
DCR Rack:
NOTE: The cooling air flow required by the equipment in a DCR Rack will vary according to several
factors, especially the distance from the Liebert PDX/PCW and each rack’s heat load. Do not obstruct
back draft dampers in the bottom plenum. We recommend running all rack PDU cables through the top
plenum.
a. After the SmartRow DCR is operational and the heat loads have time to equalize, check
the temperature in each DCR Rack with the racks’ doors closed via the 2T sensors
connected to the CANbus port on the Liebert iCOM.
• If the 2T sensor reading of a rack is lower than the average leaving air temperature of the
other racks, close the inlet damper slightly to reduce cooling air flow.
• If the 2T sensor reading of a rack is higher than the average leaving air temperature of
the other racks, open the inlet damper slightly to increase cooling air flow.
b. Reposition the air-flow adjustment dampers to equalize the cooling in each rack as
needed, referring to Figure 4.27 on the next page:
• Loosen the wing nuts.
• Move the damper to the position you want.
• Tighten the wing nuts to make sure the damper doesn’t move during operation.
c. Repeat steps a and b until the system is equalized.
