WARNING
Heavy Objects!
Only attach cables (chains or slings) to the designated lifting points. Each of the cables (chains
or slings) 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.
Other lifting arrangements could cause equipment or property-only damage. Failure to properly
lift unit could result in death or serious injury.

WARNING
Improper Unit Lift! AFDH
An AFDH drive cabinet assembly is top heavy. Test lift unit to an approximate height of no
greater than 24 inches to verify proper center of gravity lift point. To avoid dropping the unit,
reposition lifting point if unit is not level. Failure to properly lift unit could result in death or
serious injury or possible equipment or property only damage.
1. Ensure that the section of floor or concrete pad that has been prepared as the installation
location for the remote floor-mounted AFDH drive unit is as level as is possible.
2. 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 unit to be installed. For D-Frame units refer to Table 4, p. 25 .
For E-Frame units refer to Table 5, p. 25 .
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,” p. 20 .
3. Using safe lifting practices, carefully lift the cabinet only as high as is necessary to provide
enough clearance to allow attaching the previously assembled corner brackets to the base of
the drive cabinet.
a. Secure the corner brackets to the base of the drive with the remaining hardware provided
in the bracket kit.
4. Carefully maneuver the drive assembly into position over the floor section or concrete pad it
is to be installed upon.
5. Slowly lower the cabinet and set it gently onto the pad, but do not detach the lift rigging at this
time.
a. Using the angle bracket foot at each corner bracket location as a template, mark the hole
locations for the locally supplied concrete anchor bolts that will be used to secure the entire
drive assembly to the floor. NOTE: The slots in the angle bracket feet can accommodate up
to a 0.625 in. diameter concrete anchor bolt.
b. Lift the cabinet up and temporarily move it out of the way so the anchor bolt holes can be
drilled.
c. Move the AFDH cabinet back into position over the pad and gently lower it into place with
the holes in the feet lined up with the drilled anchor bolt holes. Leave the lift rigging in place
until the cabinet is properly secured to the pad using locally supplied concrete anchor bolts.
d. Confirm that the drive cabinet is firmly anchored to the pad and is stable before detaching
the rigging from the lifting points.
