Assembly instructions
Assembly of the takes professional installers
about 2 hours. If this is the first time you have assembled this
type of equipment, plan to spend more time. It is strongly recom
mended to assemble the equipment by professional installers.
You may find it quicker, safer, easier to assemble this equipment
with the help of a friend, as some of components may be large,
heavy or awkward to handle alone. It is important that you asse-
mble your product in a clean, clear, uncluttered area. This will
enable you to move around the product while you are fitting com-
onents and reduce the possibility of injury during assembly.
As with any assembled part, proper alignment and adjustment
is critical. While tightening the fasteners, be sure to leave room
for adjustments. Do not fully tighten the fasteners until instructed
to do so. Be careful to assemble the components in the sequence
presented in this guide.
