The ChlorMaker requires no spa modification. Simply attach the control panel to the Spa skirt, add 1.5 pounds of salt per 100 gallons of spa water, drape over the cell into the spa water and plug it in.
It can be a challenge to to keep the water in your spa or hot tub crystal clear and odor free. If you forget to add chlorine or bromine for a single day or the chlorine feeder runs out and you don't refill it that could lead to spa problems. Due to the higher temperature of the water the chemical balance is critical to be continuously maintained to keep it safe. Proper spa maintenance leads to your spa being safe when you want to use it. Even if the water looks good you should measure the chemical balance before use. Spa chlorine generators can greatly reduce spa problems and spa maintenance as they continuously make chlorine (or bromine) every day so you don't have to.
The ChlorMaker makes chlorine on a 3 hour cycle. Every 3 hours it starts making chlorine, and based on the power level it will turn off at some point in that 3 hours and remain in standby mode, then at the next 3 hours it will start again. At power level 5 it will be on for 45 minutes out of every 3 hours. If you use the spa and let the ChlorMaker know by pressing the boost mode button, it will be put into boost mode and be on for 3 times the normal on time. Boost mode helps to add the chlorine back after the spa is used.
