the installation requires expert knowledge.
Improper installation may cause the unit to fall,
resulting in personal injury and/or property
damage.

• Install the unit in a location that can structurally
support the weight of the unit and its mounting
hardware. Doing otherwise may result in the unit
falling down and causing personal injury and/or
property damage.

• Do not use other methods than specified to mount
the unit. Extreme force is applied to the unit and
the unit could fall off, possibly resulting in personal
injuries.

• Attach the safety wire to the unit. If not attached,
the unit could fall off, resulting in personal injury.

• Tighten each screw securely. Ensure that the unit
has no loose joints after installation to prevent
accidents that could result in personal injury.

• Do not hold the diffuser as a handle to carry the
unit. If the diffuser breaks off, the unit falls off,
resulting in possible personal injury.

• Use the specified mounting hardware in
combination. Doing otherwise may cause the unit
or component to fall off, resulting in personal injury.

• Should the following irregularity be found during
use, immediately stop operating the unit and
contact your nearest TOA dealer. Further attempt

• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.

• Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.

• Avoid touching the unit's sharp metal edge to
