secured after installation, the unit could fall down, possibly resulting in personal injury.
• Do not use other methods than specified to mount the bracket. Extreme force is applied to the unit and the

• 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. The unit or its mounts may be
subject to corrosion, that might cause it to fall or result in other accidents.
• 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.
