Do not exceed these allowances. Correct the improper
slope by building up the curb base. The material
used to raise the base must be adequate to
support both the curb and the unit weight.
WARNING
Heavy Objects!
Do not use cables (chains or slings) except as shown.
Each of the cables (chains or slings) used to lift the unit
must be capable of supporting the entire weight of the
unit. Lifting cables (chains or slings) may not be of the
same length. Adjust as necessary for even unit lift. Other
lifting arrangements may cause equipment or property-
only damage. Failure to properly lift unit may result in
death or serious injury.
Use spreader bars as shown in the diagram. Refer to the
Installation manual or nameplate for unit weight. Refer
to the Installation instructions located inside the control
panel for further rigging information.

Installation (Continued)
2. Attach adequate strength lifting cables to the lifting lugs
within the base rail.
Table 3 lists the unit weights and corner weights. To obtain
the total unit weight, add the accessory weight listed in Table
4 to the base unit weight.
The unit center-of-gravity location and dimensions are shown
in Figure 3.
Figure 4 illustrates the Installation of spreader bars to protect
the unit and to assure a uniform lift. Note that the minimum
distance between the lifting hook and the top of the unit
should be 7 feet.
3. Test-lift the unit to check all rigging and balance; make any
rigging adjustments necessary.
4. Lift the unit and position it over the curb. Align the base
rails of the unit up with the curb.
5. Lower the unit onto the curb. Make sure that the gasket on
the curb remains intact when positioning the unit.
