Rigging

A Rigging illustration and Center-of-Gravity dimensional data
table is shown in Figure 3-5. Refer to the typical unit operat-
ing weights table before proceeding.
1. Remove the shipping crate from around the unit. Do not
remove the crating from the top of the unit as illustrated in
Figure 3-5.
2. Rig the unit as shown in Figure 3-5. Attach adequate
strength lifting slings to all four lifting brackets in the unit
base rail. Do not use cables, chains, or slings except as
shown.
3. Install a lifting bar, as shown in Figure 3-5, to protect the
unit and to facilitate a uniform lift. The minimum distance
between the lifting hook and the top of the unit should be
7 feet.
4. Test-lift the unit to ensure it is properly rigged and bal-
anced, make any necessary rigging adjustments.
5. Lift the unit and position it into place.
6. Downflow units; align the base rail of the unit with the curb
rail while lowering the unit onto the curb. Make sure that
the gasket on the curb is not damaged while positioning
the unit.

General Unit Requirements

The checklist listed below is a summary of the steps required
to successfully install a commercial unit. This checklist is in-
tended to acquaint the installing personnel with what is re-
quired in the installation process. It does not replace the de-
tailed instructions called out in the applicable sections of this
manual.
[ ] Check the unit for shipping damage and material short-
age; file a freight claim and notify appropriate sales repre-
sentative.
[ ] Verify that the installation location of the unit will provide
the required clearance for proper operation.
