CORRECT CHEMICAL LEVELS

545 – 550 mV Spa Boy Optimum Range.
(Optimum Range is the default factory setting, the user may adjust higher if preferred by contacting their dealer to have it adjusted. )
Depending on the water chemistry which will be effected by bather load and spa usage, at times the ORP value will overshoot or undershoot the Optimum Range.
Note: Using a Drop Test Kit, a 0.5ppm Chlorine reading = approximately 550mV
