Unconditioned Spaces
All duct work passing through unconditioned space must
be properly insulated to minimize duct losses and prevent
condensation. Use insulation with an outer vapor barrier.
Refer to local codes for insulation material requirements.
Acoustical Duct Work
Certain installations may require the use of acoustical
lining inside the supply duct work.
• Acoustical insulation must be in accordance with the
current revision of the Sheet Metal and Air Conditioning
Contractors National Association (SMACNA) application
standard for duct liners.
• Duct lining must be UL classified batts or blankets with
a fire hazard classification of FHC-25/50 or less.
• Fiber duct work may be used in place of internal duct
liners if the fiber duct work is in accordance with the
current revision of the SMACNA construction standard
on fibrous glass ducts. Fibrous duct work and internal
acoustical lining must be NFPA Class 1 air ducts when
tested per UL Standard 181 for Class 1 ducts.

Rigging & Hoisting
WaRNING:

to ensure that whatever means are used to hoist
the unit are safe and adequate:
• The lifting equipment must be adequate for the
load. Refer to Table 3 (page 25) for unit weights.
• The unit must be lifted from the holes in the
base rails using cables or chains.
• Spreader bars are required to protect the unit
and ensure even loading. See Figure 4.
• Keep the unit in an upright position at all times.
The rigging must be located outside the units
center of gravity. Refer to Figure 12 (page 24)
for locating the center of gravity.
• All panels must be securely in place during
rigging and hoisting.
