This warranty is valid only to the original purchaser of the product, for two years from the manufacturing

day.  
Phason hereby warrants that should this product fail because of improper workmanship, Phason will 
repair the unit, effecting all necessary parts replacements without charge for either parts or labor. 

Conditions

The product must not have been previously altered, modified, or repaired by anyone other than 
Phason.

Except to the extent prohibited by applicable law, no other warranties, whether expressed or implied, 
including warranties of merchantability and fitness for a particular purpose, shall apply to this product. 
Any implied warranties are excluded.  
Phason is not liable for consequential damages caused by this product.  
Phason does not assume or authorize any representatives, or other people, to assume any obligations or

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.
