Phason controls are designed and manufactured to provide reliable performance, but
they are not guaranteed to be 100 percent free of defects. Even reliable products can
experience occasional failures and the user should recognize this possibility.
If Phason products are used in a life-support ventilation system where failure could result
in loss or injury, the user should provide adequate back up ventilation, supplementary
natural ventilation, or an independent failure-alarm system. The user's lack of such
precautions acknowledges their willingness to accept the risk of such loss or injury.
