IMPORTANT MESSAGE! Due to upcoming Department of Energy (DOE) Dedicated Purpose Pool Pump regulations and global supply chain constraints, the motor HP may have been substituted. Pentair has have replaced the pump/system ordered with a full-rated TEFC motor. TEFC motors are of higher quality and, typically, have higher efficiency than the pump ordered. The pump motor has been replaced with a comparable full-rated pump motor. The motor tag may reflect a lesser HP, however, Pentair has assured us that the performance curve for the replacement pump is the same or better than the ordered pump. Applies to skus #7675, #7676 and #7839.
