4.7 Install the Top Plenum-PDX/PCW
1. Remove the plenum side plate cover attached on the interior of the Primary
DCR Top Plenum-PDX/PCW (DCR-A-400PDX).
This side plate cover will be installed on side of the last top plenum in the row.
2. Set the DCR Top Plenum-PDX/PCW on the top of the PDX/PCW and DCR Control Panel
and Fire Suppression System.
NOTE: Take care not to damage the gasket when setting the DCR Top Plenum-PDX/PCW on the top of
the Liebert PDX/PCW and DCR Control Panel and Fire Suppression System. If the gasket is damaged,
the plenum must be removed and the gasket replaced. A damaged gasket will permit cooling air to
escape, which will reduce cooling efficiency, increase energy use and adversely affect fire-suppression
system operation.
3. Secure the plenum to the Control Panel and Fire Suppression system using the factory-
supplied (6) 1/4-in.–20 screws, nuts and washers through the top plenum and into the (6)
factory-installed nut inserts in the Control Panel and Fire Suppression system.
4. Secure the rear of the plenum to the PDX/PCW using the factory-supplied carriage bolts.
4.8 Mounting the Top Plenums-Rack
1. Referring to Figure 4.17 below, start at the center, bottom and apply D-shaped gasket material
to the side of the DCR Top Plenum-Rack that faces the DCR Top Plenum-PDX/PCW (shown in
Figure 4.19 on page 35):
• The gaskets are cut to the correct length at the factory.
• Apply the gasket continuously along the profile edge of the plenum frame.
• Apply pressure to the gasket to make sure it adheres to the frame.
2. At each corner, make a 1-in. to 1.5-in. radius, Figure 4.17 below.
3. When you reach the starting point, form a sealed joint by butting the start and finish edges
together as shown in Figure 4.17 below.
