6500-310 Sundance 880/850 Smart Heater 2000-2015
Fits all Sundance 880 and 850 models from 2000-2015.
Important Note: Plastic Smart Heaters have a slightly smaller dry well. When installing these heaters into spas manufactured prior to April 2007, you can no longer use the OEM Hi-Limit Sensor since it is too large to fit into the new heater’s sensor well. We never recommend forcing a hi-limit sensor into or drilling out a sensor well for any reason since this practice can damage the heater and result in leaks. For this reason, we recommend replacing both the Smart Heater and Hi-Limit sensor (6600-168) as a set.
