Rigging and Handling
WARNING
Use all lifting points. Improper lifting can cause severe
personal injury and property damage.
CAUTION
Lifting points may not be symmetrical to the center of gravity
of the unit. Ballast or unequal cable lengths may be required.
Lifting brackets with 2" (51 mm) diameter holes are provided
on the sides of the unit.
Use spreader bars, 96" to 100" (2438 to 2540 mm) wide, to
prevent damage to the unit cabinet. Avoid twisting or uneven
lifting of the unit. The cable length from the bracket to the hook
should always be longer than the distance between the outer
lifting points.
If the unit is stored at the construction site for an intermediate
period, follow these additional precautions:
1.
Support the unit well along the length of the base rail.
2.
Level the unit (no twists or uneven ground surface).
3. Provide proper drainage around the unit to prevent
flooding of the equipment.
4.
Provide adequate protection from vandalism, mechanical
contact, etc.
5.
Securely close the doors.
6.
If there are isolation dampers, make sure they are properly
installed and fully closed to prevent the entry of animals
and debris through the supply and return air openings.
7.
Cover the supply and return air openings on units without
isolation dampers.
