age in transit, handling or installation; (iii) modifications, adjustments, repairs, or alterations made by unauthorized 

persons; or (iv) other causes not arising out of defects in workmanship or materials. Thermaco shall not be respon-

sible for damage to products resulting from vault flooding, sewer line back-up, pumping or lift station failure, ambient
