CONTOUR CT28 WALL & CEILING INSTALLATION
•
Using a 3 mm hex wrench, remove the two rear M5×25 mm
countersunk screws from the top of the CT28 enclosure.
Figure 97. Inserting the M5 swivel
hoist rings in the rigging points on
the top of the CT28 enclosure.
•
Thread the M5 eye bolts into the rigging points from which the
screws were removed and tighten them with your fingers.
Figure 98. Torquing the hoist rings.
•
Tighten the two hoist rings into the rigging points to the to
the torque specified by the manufacturer. The tools necessary
will be specified in the product literature provided by the
manufacturer of the third-party hoist rings.
Installing the Angle Bar
The Angle Bar combined with the Horizontal Mounting Bracket can be
installed horizontally on a ceiling to provide a tilt angle from -15° to -75°,
or vertically on a wall to allow a steeper downward tilt (down to -75°) than
would be possible with the Horizontal Mounting Bracket alone.
WARNING
Before beginning this installation, it is necessary to
ascertain the construction type, load-bearing capability
and durability of the wall or surface. Bear in mind that
the CT28 speaker enclosure weighs 20 kg (44 lb),
and can be positioned in such a way as to extends
the mass of the enclosure out to perpendicular from
the mounting surface. Therefore the increased forces
imposed on the fixings and wall must be taken into
account.
Careful thought must be given to ensure that the
wall structure is strong enough to safely support the
total load with the proper Factor of Safety required
by local, state and national norms or legislation. If
the facility or venue is open to the public and the
mount is within reach of the public, the installer should
take into consideration possible miscreant behavior or
tampering when determining the appropriate factor of
safety. If the wall structure is deemed incapable of
supporting the load, consideration should be given to
strengthening and/or stabilizing the wall or adopting
an alternative method of installation. In the case of
any doubt, architects, structural engineers or other
specialists should be consulted.
WARNING
Risk of Electric Shock
Drilling into hidden electrical wiring within walls can
result in serious injury or death, fires and property
damage.
BE AWARE OF WHAT YOU ARE DRILLING INTO.
Before drilling holes in any wall or surface, make sure
that it does not conceal electrical wiring or conduits.
Consult the wiring diagram of the facility or venue and
check for nearby outlets, switches or junction boxes
that could indicate concealed wiring, be it electrical
mains, network, telephone or other infrastructure.
