Installing the Rack Kit

Every ARCvault 48 comes with a tray-style Rack Kit that allows you to easily install and remove the unit without having to engage side rails. The Rack Kit includes all mounting hardware.

WARNING: It is recommended that a mechanical lifter (or at least two people) be used to raise and align the unit to prevent injury during installation.

WARNING: Use care when inserting or removing an ARCvault unit into or out of a rack to prevent the accidental tipping of the unit causing damage or personal injury.

1.Locate and mark the holes for the rails and retaining screws:

a.Starting with the right front flange, at the bottom of the rack (or from the top of a previously mounted component), locate the first set (Figure 2) of three holes with equal gaps of 5/8 inch (1.6cm).
