The SmarterSpa DO easily drapes across the edge of the hot tub or spa and hangs into the water. The SmarterSpa DO is a revolutionary way to maintain your hot tub or spa. It is the first salt chlorine generator with a built-in chlorine detector, replacing the traditional timed cycle method to produce chlorine. The SmarterSpa DO has to be plugged into a GFCI 110V outlet 10 feet from the hot tub. It is recommended to have the hot tub cover off the spa for 15-20 minutes every few days to allow the chemical vapours to vent off if the hot tub is not used regularly.
The SmarterSpa is designed so that it can be mounted to the hot tub skirt for easy access. SmarterSpa DO can run on any type of hot tub heating system but it is recommended to have or eventually replace the heater element with a titanium heater element.
