• Leave the installation of the unit to your TOA dealer because
the installation requires expert experience and skills. The unit
may fall off if incorrectly installed, resulting in possible personal
injury.

• Have the unit checked periodically by the shop from where it
was purchased. Failure to do so may result in corrosion or
damage to the mounting bracket that could cause the unit to
fall, possibly causing personal injury.
