Positioning the expansion rack

Procedure

Determine the position of each expansion rack to be installed to this storage facility.
1. When viewed from the front of the storage facility, each expansion rack is installed to the right. See Figure 1.
2. Use each expansion rack number label to ensure the expansion rack is for this the storage facility. The label is located at the left side of the rack, behind the front door, below the upper door hinge. The expansion rack label must list the correct the storage facility serial number.
  
  Figure 1. Rack serial number and rack number labels (Models 98x, 8xE)
  
  Note: Rack-4 and Rack-5 not shown. Some models do not use a Rack-3.
  
  Note: In the steps that follow, "expansion rack" refers to the expansion rack you are installing, while "storage facility" refers to the existing storage facility including any expansion racks already installed.
Does the expansion rack you are installing have EMI seals on the left side?
- Yes. Go to step 5.
- No. Continue with the next step.
Remember: You checked for this in step 1 of Extending the rack to full height and attaching to the storage facility.
Install side trim pieces with gaskets on right side of the storage facility at top, bottom, front, and rear. See Figure 2. The screws that are used to secure the trim pieces to the racks are described in Table 7.

Note: Each trim piece can come in one or two parts. Refer to Table 7.
1. Install front and rear trim pieces with gaskets and secure with screws. Each screw location has two holes. Insert the screw into the smaller hole. See Figure 3.
2. For models with extension panels, install trim pieces with gaskets on the right front and right rear extension panels.
3. Install the top and bottom trim pieces and secure with screws. Top piece gasket 1 goes up, bottom piece gasket 2 goes down. See Figure 3.

Install side trim pieces (without gaskets) on left side of the expansion rack that you are installing at front and rear. See Figure 4.
Notes:
- Left side trim pieces (without gaskets) are front and rear only, there are no top or bottom pieces.
- Each trim piece can come in one or two parts. Refer to Table 7.
1. Install front and rear trim pieces and secure with screws. Each screw location has two holes. Insert the screw into the smaller hole.
2. For models with extension panels, install trim pieces (without gaskets) on the left front and left rear extension panels.

Note: Extension panels not shown.
Remove wheel chocks (if inserted) or raise the stabilizer feet of the expansion rack (if lowered).
Roll the expansion rack being installed into position.
1. Move the rack outriggers to stowed (operating) position for final positioning of each rack.
2. To move each outrigger, pull down on the release handle 2 located under the outrigger, and push the outrigger in. See Figure 5.

Position the expansion rack against the storage facility.
1. Position the rear of the expansion rack against the rear of the storage facility.
2. Pivot the front of the expansion rack against the front of the storage facility.
  
  Note: The rear rack wheels do not swivel. Position the rear of the expansion rack as close as possible to the storage facility before pivoting the front of the expansion rack.
Fasten the expansion rack to the storage facility. The screws and washers that are used to fasten the racks together are described in Table 7 and Table 8 in topic Extending the rack to full height and attaching to the storage facility.
1. Basic racks are fastened by using five screws with washers in the front and five bolts with washers in the rear. See Figure 6 and Figure 7.
2. Extension panels (if present) are fastened by using one additional screw with washer in the front and one additional screw with washer in the rear.
  
  Note: Suggested method is to install screws working top to bottom at rear, then top to bottom at front. You must partially lower the left front stabilization foot of the expansion rack to insert the bottom screw.
