🔍 Key Concepts

• High head pressure in a refrigeration system usually relates to condenser problems (heat rejection side) • Corrective action should normally reduce pressure, not push limits of safety controls • Effect of condenser water flow (too little vs. too much) on condensing temperature and pressure

💭 Think About

• Ask yourself: what condition in the condenser would make the discharge (head) pressure rise and cause short cycling? • Which choice directly addresses improving heat rejection, rather than masking the symptom by changing a safety setting? • For each option, imagine what happens to the condensing temperature and pressure if you do that action.

✅ Before You Answer

• Verify which option improves heat transfer in the condenser and tends to lower head pressure • Be sure you are not selecting an option that defeats a safety device or increases risk • Check whether the action would be a first troubleshooting step (simple system check) before more invasive work like purging or opening equipment
