What should be done to ensure clear and effective system operation?

To ensure clear and effective system operation, running the system with an open faucet is essential. When water treatment systems are commissioned or serviced, having an open faucet allows air to escape from the system, which helps to prevent air locks that can disrupt water flow and affect overall system performance. This practice enables the system to prime properly, ensuring that any particulate matter can be flushed out before normal operation begins, maintaining water quality and efficiency.

The other practices, such as installing the system with closed faucets or leaving all valves in a closed position, may hinder the system's ability to operate correctly by preventing water flow, leading to potential malfunction or incomplete system activation. Running without testing components overlooks the necessary verification steps that ensure each part functions as intended, which is crucial for optimal operation.
