Always prevent a new heater or heater element from coming on (turn down the temp setting) until you have run the pump on high several minutes to get all the air out of the piping, BEFORE you even turn up the heat. This prevents 'dry-fire' which will damage any heater. Follow this whenever you drain and fill your spa, change a filter cartridge, etc. Tub owners do not realize when water level drops for any reason, evaporation, people getting out of the spa, etc., when the skimmer sucks in air and the heater is on, you are damaging the heater.

Unit is fully tested and certified for resistance and electrical values multiple times before packaging and shipping. Resistance value is Certified.

Also available in 5.5kW

Like any flothru spa heater it must never see a lack of flow or air in the system with the heater on, it will 'dry-fire' and burn out and test open for resistance and the Waterway warranty will not cover open, dry-fire abuse.
