surface. Doing so may result in the unit falling down and causing personal injury and / or property
damage.
• Install the unit only in location that can structurally support the weight of the unit and the mounting
bracket. Doing otherwise may result in the unit falling down and causing personal injury and / or
property damage.
• Since the unit is designed for indoor use, do not install it outdoors. If installed outdoors, the aging of
parts causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a
danger of electric shock.
• Owing to the unit's size and weight, be sure that at least two persons are available to install the unit.
Failure to do so could result in personal injury.
• Do not use other methods than specified to mount the bracket. If extreme force is applied to the unit,
the unit could fall off, resulting in personal injuries.

may cause the unit to fall, resulting in personal injury.
• Ensure that all screws are securely tightened. If they are not tightened or firmly secured after
installation, the unit could fall down, possibly resulting in personal injury.
• Use the specified mounting bracket in combination. Doing otherwise may cause the unit or
component to fall off, resulting in personal injury.

damaged by excessive vibration, potentially causing the unit to fall, which could result in personal
injury.
