OPERATING MANUAL AND USER GUIDE

WLA-12 Fly Frame
Only use the Wharfedale Pro WLA- with the WLA Flyframe. Ensure that only
rated, certified hardware such as turnbuckles, shackles and chains are used.
Ensure that all truss, structures and flying hardware are capable of suspending
the entire array, plus flying hardware, to a suitable safety factor.
Rigging, suspending and mounting should only be attempted by
experienced qualified professionals. Incorrect usage can result in
damage to equipment and property, injury and even death. Under
no circumstances should you attempt to rig, suspend or mount
these speakers unless you are fully qualified and certified to do
so by relevant local, state and national authorities. If you are not
properly qualified or do not know of pertinent regulations consult
qualified personnel for advice. Consult a structural engineer
before suspending a speaker system and ensure that the total
weight of your system can be held by the truss or mounting
surface.
Inspect all mounting hardware before your line array is flown. If there is any
damage or distortion to any mounting hardware do not fly the array until
any damaged hardware is repaired or replaced. Only use Wharfedale Pro
supplied Quick Release Pins, contact your Wharfedale Pro Distributor if any
Quick Release Pins are lost or damaged.
