General Lifting Considerations
Before preparing the unit for lifting, estimate the
approximate center of gravity for lifting safety. Because of
placement of internal components, the unit weight may be
unevenly distributed, with more weight in the coil and fan
areas. Approximate unit weights are provided in the
Dimensions and Weights chapter. Refer to the unit
submittals for actual weights. Test the unit for proper
balance before lifting.
Lifting Indoor Units
Always rig subassemblies or sections as they ship from
the factory. Never bolt sections together before rigging.
• Make the loop of the sling parallel to the direction of
airflow, if possible.
• When hoisting the unit into position, use the proper
rigging method, such as straps, slings, spreader bars
and lifting lugs for protection and safety. See the
Figure 12 and Figure 13.
• For unit sizes 3-30 with integral base frame, use field-
provided spreader bars and slings to rig the units and
subassemblies as shown in the Figure 14. The air
handler is not designed to be lifted or rigged from the
top of the unit.
WARNING
Risk of Unit Dropping!
Failure to follow instruction below could result in death
or serious injury. To prevent modules/subassemblies
from dropping, ALWAYS place, assemble, and suspend
them one at a time.
WARNING
Improper Unit Lift!
Failure to properly lift unit could result in unit dropping
and possibly crushing operator/technician which could
result in death or serious injury and possible equipment
or property-only damage. Test lift unit approximately 24
inches to verify proper center of gravity lift point. To
avoid dropping of unit, reposition lifting point if unit is
not level.
WARNING
Heavy Objects!
Failure to follow instructions below or properly lift unit
could result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
slings used to lift the unit must be capable of
supporting the entire weight of the unit. Lifting slings
may not be of the same length. Adjust as necessary for
even unit lift.
