4. Installation of the CHEMTROL 250

1). CONTROLLER - Connect the controller to the 110 or 230V output of the Timer in parallel to the recirculation pump. This will prevent accidental feeding of chemicals when the pump is not running. Make sure to follow the electrical code.

2). SENSORS - Install the ORP and pH sensors on the recirculation line or on the optional bypass line. The two sensors can be mounted directly on the main recirculation line with 2" PVC tees, as shown on the schematic. For recirculation lines over 2" in diameter, the sensors should be mounted on a 1/2" bypass line.

3). CHEMICAL FEEDERS - Connect the chemical feeders to the 110 or 230V controller outputs, according to the manufacturer's instructions, making sure to inject the chemicals downstream of the sensors. For a bromine or chlorine erosion feeder, install a corrosion-resistant solenoid valve on the intake line of the feeder. The controller is compatible with most ozonators and electrolytic generators.
