EnviroSmarte CO2 pH Control System ·

Installation Install the “CO2 pH Control Assembly” on a secure surface on the spa frame using the supplied or other screws. Assemble per the diagram, noting flow direction of the CO2 gas and water. Be sure to open valve on the “CO2 Tank”.




The initial settings should be between 4-6 seconds “On Time” and 2-3 hours “Off Time”. If pH is trending higher than 7.2, increase “On Time” and/or decrease “Off Time”. Reverse if pH is trending lower than 6.8.




Maintenance The “Plunger” on the end of the “Flow Regulator” can be observed and can indicate if the CO2 Tank has pressure. If there is pressure, the Plunger should stick out and when pushed, snap back out. Depending on usage, spa size and tank size, the CO2 Tank must be refilled at 1-6 month intervals. Turn the tank valve “off” and then unscrew the Flow Regulator from the tank.
