Where must automatic chlorinators be installed in relation to the heater?

  1. Upstream of the heater

  2. Downstream of the heater

  3. Upstream of the filter

  4. Downstream of the filter

The correct answer is: Downstream of the heater

Automatic chlorinators must be installed downstream of the heater to ensure that the heated water does not cause any potential damage to the chlorinator itself. By placing the chlorinator in this position, it allows the water to first go through the heater where it is treated and then move to the chlorinator, where chlorine is introduced to sanitize the water effectively. If the chlorinator were positioned upstream of the heater, the heat could potentially degrade the chlorine and reduce its effectiveness for sanitization. Additionally, positioning it incorrectly could introduce unwanted reactions within the system that may compromise both the chlorinator's operation and the overall water quality. Understanding the proper placement of automatic chlorinators in relation to heaters is crucial for maintaining an effective and efficient water treatment system.
