Installation Guidelines
Rigging
Rig units using straps or a sling. Fasten strapping under the
skid that ships with the section. If a field-installed mixing box
is attached, adjust to balance the unit properly.
To avoid damage to the unit cabinetry, use spreader bars.
Position spreader bars to keep cables from rubbing the frame,
connections, or panels. Before hoisting into position, test lift
for stability and balance. Avoid twisting or uneven lifting of
the unit.

Unit Leveling
Place the equipment on a flat and level surface (or verify that
unit is level when hanging from the ceiling). Where the surface
irregularities allow the equipment to distort, shim the base of
the unit to a straight line. Distorted units can cause misfit or
binding of the doors and panels and improper draining of drain
pans.
