3.0 INSTALLATION AND USE
3.1 BEFORE EACH USE:
Carefully inspect the Emergency Descent Device in accordance with Section 5 of this instruction.
3.2 PLANNING:
Plan your emergency escape system and how it will be used before starting your work. Consider all factors
that will affect your safety before, during, and after an escape. Consider the following when planning your system:
A. ANCHORAGE:
Select a rigid anchorage point that is capable of supporting the load as specified by Section 2.3 in this
instruction.
B. DESCENT PATH AND LANDING AREA CLEARANCE:
The planned descent path must be unobstructed. The
landing area must be clear of obstructions to permit safe landing of the user. Failure to provide an unobstructed
descent path and landing area may result in serious injury.
C. TEST THE SYSTEM:
3M Fall Protection recommends performing a test descent using a 120 lb (55 kg) test weight.
The descent speed should be uniform and allow the user to reach the landing area safely. The descent speed should
be approximately as stated in Section 1.2.B.
NOTE:
The Emergency Descent Device does not need to be returned to a service center after a test descent.
D. SHARP EDGES:
Avoid using this equipment where system components will be in contact with or abrade against
unprotected sharp edges. If working with this equipment near sharp edges is unavoidable, cover the sharp edge with
a heavy pad.
E. AFTER A DESCENT:
After use of the Emergency Descent Device, the auto retract function retracts the lifeline back
into the device under control. The Emergency Descent Device must be serviced by an authorized service center after
a descent as the result of an emergency.
3.3 CONNECT THE EMERGENCY DESCENT DEVICE TO ANCHORAGE:
Figure 3 illustrates connection of the Emergency
Descent Device to an anchorage. See Section 2 for compatibility and anchorage strength requirements.
DROPPED OBJECT PROTECTION:
The handle of the Emergency Descent Device can be connected to secondary
anchorage with a Tie-Off Adaptor to prevent dropping the device during installation on primary anchorage.

3.4 CONNECT THE EMERGENCY DESCENT DEVICE TO A GUIDE CABLE:
Some sloped angle descent applications may
require attaching the Emergency Descent Device to the guide cable. Use the Guide Cable Sleeve and Suspension Bar Kit
to attach the Emergency Descent Device to the Guide Cable as shown in Figure 5.
3.5 CONNECT TO YOUR BODY SUPPORT:
A full body harness
or other means of supporting the user must be used with the
Emergency Descent Device device. Do not use a body belt with the
Emergency Descent Device. Attachment of the Snap Hook to the frontal or
sternal D-rings on a full body harness is recommended (Figure 4). Ensure
the D-ring is positioned to hold yourself upright. See the full body harness
manufacturer’s instructions for more information.
WARNING:
Do not use a body belt with the Emergency Descent
Device. Body belts do not support your entire body, which may result
in serious injury.
