2: Installation Procedures
Removing a Tall Rack from the Shipping Crate
Warning:
In its maximum configuration, a tall-rack system weighs approximately
1,130 lb (512.56 kg). Use caution when you unpack and move this rack. Ensure that the
rack remains on a level surface and that the rack weight remains evenly distributed
across the four casters.
To unpack a tall rack, you will need the following tools: extension, 6-inch, 3/8-in. drive;
13-mm standard 3/8-in. drive socket; and ratchet, reversible, 3/8-in. drive.
Refer to Figure 2-6 as you follow these steps; the numbered illustrations correspond to
the numbered steps.
1. Ensure that the temperature of the rack is acclimated to the environment in which
you are installing it and that the system crate is in a stable, upright position.
2. Remove the bands that secure the crate.
Note: Brace the wooden ramp as you remove the horizontal band that surrounds the
crate and the wooden ramp. The ramp moves freely after you remove this band.
3. Place the ramp so that the three holes in the edge of the ramp align with the pegs in
the base of the pallet deck.
4. Remove the cardboard cover, the two cardboard sidewalls, and the foam cushion.
5. Remove the bolts that secure the rack to the pallet deck.
a. Remove the top four bolts from the rear mounting bracket; do not remove the
bottom bolts.
b. Remove the four bolts that secure the front mounting bracket and tip tray to the
bottom of the pallet deck. Set the tip tray aside.
c. Remove the top four bolts from the front mounting bracket. Set the mounting
bracket aside.
6. Use two people to roll the rack out of the crate and down the ramp.
Warning:
Use extreme caution when you roll the tall rack down the ramp. Personal
injury and system damage could result if the rack becomes unbalanced or gains too
much momentum when it rolls down the ramp.
7. Bolt the tip tray to the front of the rack before you move the rack to its designated
location. This tray prevents the rack from tipping while you move that rack.
