Installation
Leveling the Rack
The Rack will need to be properly level prior to the installation
of any Rack Equipment to ensure stability. The surface the
Rack is located must also be a at level surface to support the
weight of the Rack and Rack Equipment installed.
1. Determine the location of the Rack. Once this location is
determined, use the level to ensure that the surface is a at
level surface.
2. Using an 14 mm Open-Ended Wrench, lower the leveler (4
located next to the Casters) by turning it clockwise until the
base of the Leveler is tightly pressed against the surface,
supporting the weight of the Rack.
3. Place the Level on the top of the Rack to ensure that the
Levelers are adjusted correctly. If the Rack is not level make
the required adjustments to the Levelers until the Rack is
level.
Securing the Rack to the Floor
You can use the Pallet Brackets and Bolts used to secure the
Rack to the shipping Pallet to securely fasten the Rack to the
oor.

bottom of the Rack’s Door Frame. The Pallet Brackets can
be mounted on the exterior or interior of the Rack.
2. Using a 13 mm Socket and Wrench, insert two of the Bolts
through the Pallet Bracket and into the Rack.
