conditioned spaces. Follow latest Sheet Metal and Air Con-

5. Secure all ducts to building structure. Flash, weatherproof, and
vibration-isolate duct openings in wall or roof according to
good construction practices.
Step 5—Rig and Place Unit
Use spreader bars or crate top when rigging the unit. The units
must be rigged for lifting as shown in Fig. 7. Use extreme caution
to prevent damage when moving the unit. Unit must remain in an
upright position during all rigging and moving operations. The unit
must be level for proper condensate drainage; the ground-level pad
or accessory roof curb must be level before setting the unit in
place. When a field-fabricated support is used, be sure that the
support is level and that it properly supports the unit.
UNITS WITHOUT BASE RAILS-Accessory rigging brackets are
recommended to be used for rigging. Install brackets as follows:
