WARNING: Consult your doctor if there is reason to doubt your fitness to safely absorb the shock from a fall arrest. Age

and fitness seriously affect a worker's ability to withstand falls. Pregnant women or minors must not use DBI/SALA self

retracting lifelines.

3.1 BEFORE EACH USE inspect this equipment according to section 5.0. Do not use this equipment if inspection

reveals an unsafe or defective condition. Plan your use of the fall protection system prior to exposing workers to

dangerous situations. Consider all factors affecting your safety before using this system.

A. Read and understand all manufacturer's instructions for each component of the personal fall arrest system. All

DBI/SALA anchorage connectors, harnesses, and connecting subsystems are supplied with separate user

instructions. Keep all instructions for future reference.

B. Review sections 1.0 and 2.0 to ensure system limitations and other requirements have been followed. Review

applicable information regarding system clearance criteria. Ensure changes have not been made to the system

installation (i.e. length) or to the job site that could affect the required fall clearance. Do not use the system if

changes are required.

3.2 SYSTEM INSTALLATION: Figures 1 and 2 show typical Single Span and Multiple Span Vacuum Anchor horizontal

lifeline installations. The horizontal lifeline system should be positioned at a level that will minimize free fall while

allowing ease of use. The horizontal lifeline should be positioned near the work location to minimize swing fall

hazards. The connecting subsystem length should be kept as short as possible to reduce the potential free fall and

required clearance distance. Both Vacuum Anchors must be installed at approximately the same elevation so the

horizontal lifeline system is not sloped more than five degrees.

Step 1. Determine the locations of the Vacuum Anchors and evaluate the Anchorage Structure strength in

accordance with section 2.3. Determine the span length and evaluate the required clearance using Figures 6

and 7 along with Tables 1 and 2. For Multiple Span Systems, use the length of the longest subsystem to

evaluate fall clearance.

Step 2. Attaching Vacuum Anchors: Refer to the Vacuum Anchor instruction 5902157 for complete installation

information.

Step 3. Secure each end of the horizontal lifeline to the Vacuum Anchors with the snap hook or carabiner. Loosen

and reposition the rope tensioner as required.

Step 4. Remove the slack from the horizontal lifeline by pulling the rope through the tensioner by hand. To tension

the horizontal lifeline, using a pointed bar or a 1-1/8 inch wrench, turn tensioning nut clockwise until

tensioning is no longer possible. Do not modify the rope tensioner to achieve greater lifeline tension. See

Figure 8. The final tension will be 300 to 450 lbs. (1.3 - 2.0 kN).
