Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
WARNING
When Installing the Unit
• Do not use any methods other than specified to mount the bracket. 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.
• Use nuts and bolts that are appropriate for the ceiling’s or wall’s structure and composition. Failure to do so
may cause the unit to fall, resulting in material damage and possible personal injury.
• Tighten each nut and bolt securely. Ensure that the bracket has no loose joints after installation to prevent
accidents that could result in personal injury.
• Avoid installing the unit in locations exposed to sea breeze or corrosive gas. Mounts may become corroded,
eventually causing the unit to fall off, which could result in personal injury.
• Do not mount the unit in locations exposed to constant vibration. The mounting screws and/or bolts may be
loosened by excessive vibration, potentially causing the unit to fall, which could result in personal injury.
• To prevent lightning strikes, install the unit at least five meters away from a lightning rod, and yet within the
protective range (angle of 45°) of the lightning conductor. Lightning strikes may cause a fire, electric shock
or personal injury.
• When installing the unit in the snowy area, take appropriate measures to prevent snow from lying on the
unit. If the snow lies on the unit, the unit may fall, causing personal injuries.
• Be sure that at least two persons are available to install the unit. Failure to do so could result in personal
injury.
• Avoid installing the unit at heights exceeding 16 meters above the ground since the unit could be exposed to
unexpected strong winds that might cause it to fall or result in other accidents.
When the Unit is in Use
• Do not touch the unit during thunder and lightning, as this may result in electric shock.
