  IMPORTANT NOTE: This Smart Heater has a slightly smaller dry well. When installing these heaters in spas manufactured before April 2007, you can no longer use the OEM Hi-Limit Sensor, as it is too large to fit in the new heater's sensor well. You will need to replace both the Smart Heater and Hi-Limit Sensor this is sold with the set.
