1. Prepare lifting equipment and rigging.
a. Depending upon the model type, a unit-mounted
AFDH
can weigh up to 1400 pounds. Confirm the
weight of the AFDH drive. See Table 5, Table 6 and
Table 7.
b. Verify that the intended lifting device and rigging
has
the capacity to safely handle the load before
hooking up to the two factory provided lifting points
on top of the cabinet assembly.
c. Use the appropriate rigging techniques to ensure
that
the cabinet assembly will be balanced about its
center of gravity during lifting. Refer to
“Recommended Rigging and Lifting Procedures for
AFDH Drive Units,”.
2. Implement safe lifting practices, carefully lift the
cabinet
and position it over the mounting brackets on
the evaporator.Slowly lower the cabinet until the AFDH
panel flush and lineup with the motor terminal access
bolt pattern.

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
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings) may
not be of the same length. Adjust as necessary for even
unit lift.
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 equipment or
property-only damage. An AFDH cabinet assembly is
top heavy. 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
Unit Lowering!
Do not drop the drive cabinet assembly onto the
evaporator mounting brackets when setting it into
position! Dropping the cabinet onto the brackets could
result in damage to the drive cabinet, the brackets, and/
or the evaporator shell.
