Lifting Considerations

Figure 2. Recommended

attachment to lifting lugs.

• Before lifting the unit, estimate the approximate center of gravity for lifting

safety. Because of the placement of internal components, the unit weight may

be unevenly distributed, with more weight in the coil and fan areas. Refer to

the unit submittals for section weights. Test the unit for proper balance and

rigging before lifting.

• Always assemble unit at the installation site. Never bolt sections together

before rigging.

• Always rig subassemblies or sections as they ship from the factory. See the

unit submittal drawings for correct placement of sections.

• Lift all sections individually using all lifting lugs provided. See Figure 2. See

specific instructions for handling the pipe cabinet (see “TCC Wall Section

Assembly (Typical)” on page 37) and inlet and exhaust hoods (see “Outdoor

Unit Weather Hood(s)” on page 52).

Figure 3. Use proper lifting and rigging methods • Make the loop of the sling parallel to

the direction of airflow whenever

possible.

• Each of the cables used to lift the unit

must be capable of supporting the

entire weight of the unit.

• When hoisting the unit into position,

use the proper rigging method, such

as straps, slings, spreader bars, or

lifting lugs for protection and safety.

See Figure 3.

• The air handler is not designed to be

lifted, rigged or ceiling suspended

from the top of the unit.

• Never lift units in windy conditions.

Personnel should be positioned

overhead and on the ground to guide

the crane or helicopter operator in

positioning the sections.

• Never stack the pipe cabinet and inlet

hoods on the unit as the unit is being

lifted.

• Do not attach the intake/exhaust

hoods to the unit prior to lifting the

unit. Doing so may damage the

equipment. Attach the hoods to the

unit only after all sections are in place.

• Remove all wooden blocks before

installing the unit to the roof curb.
