IMPORTANT NOTE: This Smart Heater has 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. You will need to replace both the Smart Heater and Hi-Limit Sensor (SD6600-168) as a set.
Plastic Smart Heaters (6500-310 240V/5.5 kW, 6500-315 230V/2.7 kW, 6500-316 230V/5.5kW) 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 at the same time.

Tech Note: If replacing a discontinued heater such as E2550-0351ET you may need this adapter as well 425-1030. This part is 3/4 barb adapter fitting.
