Where should manual purging of a condenser occur when it is turned off?

• A. From the lowest point of the condenser
• B. From the highest point of the condenser
• C. From the side vent of the condenser
• D. From the compressor outlet

Answer: (B)

Manual purging of a condenser should occur from the highest point of the condenser because this is where any trapped air, non-condensable gases, or moisture would accumulate. In a typical hydronic or refrigeration system, the natural tendency of air is to rise due to its lower density compared to the refrigerant or fluid being used in the system. By purging from the highest point, the process ensures that these unwanted substances can be effectively removed, which helps maintain optimal efficiency and performance of the system. Additionally, purging from this location reduces the risk of liquid refrigerant or coolant escaping during the process, facilitating a safer and more efficient purging operation.
