The low-level alarm on the holding tank must be set to operate in what manner?

The low-level alarm on the holding tank must be set to operate continuously to ensure the system’s safety and efficiency. A continuous alarm allows for immediate notification when the water level drops below a predetermined threshold. This is critical for preventing potential issues such as pump damage, system malfunction, or inadequate water supply in the dialysis process.

Having the alarm operate continuously means that it will consistently monitor the water level and alert the operators in real-time, enabling them to take prompt action if necessary. This proactive approach is essential in maintaining optimal water levels for proper system functioning and ensuring patient safety.

Other options, such as intermittent operation or function only during operational hours, would not provide the necessary level of monitoring and could lead to unsafe conditions if the alarm fails to activate during off times or periods of low activity. Additionally, requiring weekly checks does not provide the immediate feedback necessary for a critical system like this, where continuous adjustment and response to water levels are paramount.
